Tirzepatide is a dual GIP and GLP-1 receptor agonist developed as a once-weekly injectable treatment for type 2 diabetes and obesity. It is a synthetic 39-amino-acid peptide that activates two gut incretin hormone receptors at the same time, and it is marketed under the brand names Mounjaro for diabetes and Zepbound for chronic weight management. First approved in the United States in 2022, it has since been authorized for obstructive sleep apnea and studied across a range of cardiometabolic conditions.
Retatrutide (development code LY3437943) is an investigational once-weekly injectable peptide that activates three gut and pancreatic hormone receptors at once: the GIP, GLP-1, and glucagon receptors. Developed by Eli Lilly, it is being studied for obesity, type 2 diabetes, and fatty liver disease. In a Phase 2 obesity trial it produced substantial weight loss, and it has advanced into Phase 3 testing.
ATX-304 is a direct, pan-AMPK activator, a small molecule that switches on AMP-activated protein kinase, the cell's master energy sensor and central regulator of metabolism. In preclinical studies it reprograms cellular metabolism toward fat oxidation and away from lipid synthesis, reducing body fat, cholesterol, and fatty liver, and it protects the kidney from injury by shifting energy metabolism [1][2]. As a next-generation metabolic activator it is an investigational compound of strong interest for obesity, fatty liver disease, and tissue protection, though it remains preclinical [2].
Alpha-lipoic acid (ALA), also called lipoic acid or thioctic acid, is a naturally occurring organosulfur compound that serves as an essential cofactor for several mitochondrial enzymes involved in energy metabolism. It is soluble in both water and fat and is widely marketed as a dietary antioxidant supplement, while in some countries a pharmaceutical form is used to treat the symptoms of diabetic neuropathy.
American ginseng (Panax quinquefolius) is a slow-growing perennial herb of the ivy family, native to the hardwood forests of eastern North America and prized for its aromatic root. It has been harvested and traded for centuries, especially for export to East Asia, where it is used in traditional medicine and valued as a tonic distinct in character from Asian ginseng. Its roots contain ginsenosides, and modern research has examined it for effects on blood sugar, cognition, cancer-related fatigue, and the common cold [1][2].
Benfotiamine is a synthetic, fat-soluble derivative of thiamine (vitamin B1), created to be absorbed more efficiently than ordinary water-soluble thiamine. Once in the body it is converted to thiamine and raises tissue levels of the active cofactor, which boosts the enzyme transketolase and helps steer excess glucose away from the biochemical pathways that damage tissues in diabetes. It is used, chiefly in Europe, for diabetic nerve pain and is sold elsewhere as a dietary supplement.
Berberine is a bright-yellow isoquinoline alkaloid found in several plants, including barberry, goldenseal, and Chinese goldthread, and used for centuries in traditional Chinese and Ayurvedic medicine. Modern research has focused on its ability to lower blood sugar and improve cholesterol and other lipids, effects that work largely by activating the cellular energy sensor AMPK. It is widely sold as a dietary supplement, though its absorption is poor and it is not an approved drug in Western countries.
Chaga is the common name for Inonotus obliquus, a fungus that grows as a hard, blackened mass on birch and other trees in the cold forests of the Northern Hemisphere [1]. Although its charred-looking growth resembles burnt wood, it is actually a sterile mass of fungal tissue rich in melanin, and it has a long history in folk medicine across Russia and northern Europe, where it is often brewed as a tea [1][2]. Modern laboratory research has examined chaga extracts and their polysaccharides for antioxidant, immune, and anticancer activity, but strong clinical evidence in people is lacking, and its very high oxalate content raises safety concerns with heavy or prolonged use [1][2][3].
Chromium picolinate is a coordination compound of trivalent chromium and picolinic acid that is sold as a dietary supplement. It is promoted mainly for blood sugar control, body composition, and weight management, on the premise that chromium supports the action of insulin. Systematic reviews of clinical trials have generally found the supporting evidence weak and inconsistent, and no chromium deficiency state is recognized in otherwise healthy people.
Cinnamon is a spice obtained from the dried inner bark of several evergreen trees in the genus Cinnamomum. It has been used since antiquity as a fragrant flavoring and in traditional medicine, and it owes its characteristic aroma largely to the compound cinnamaldehyde. Commercial cinnamon falls into two broad groups, the milder Ceylon or true cinnamon and the more common, stronger cassia, which differ markedly in their content of the compound coumarin.
Citrus bergamot refers to the bergamot orange (Citrus bergamia), a Mediterranean citrus fruit best known for flavoring Earl Grey tea and for the essential oil used in perfume. As a supplement it is standardized to the bergamot polyphenolic fraction, a mixture of flavonoids studied mainly for lowering cholesterol and improving cardiometabolic markers. The clinical evidence is encouraging but comes largely from small trials.
Cyanidin is a naturally occurring flavonoid pigment belonging to the anthocyanidin class, responsible for many of the red, purple, and magenta colors seen in fruits, flowers, and leaves. It is widespread in plants and especially abundant in berries, red cabbage, red grapes, and other deeply colored produce, usually present as sugar-bound forms called anthocyanins such as cyanidin-3-glucoside. Like other anthocyanidins its color shifts with acidity, and it is studied for antioxidant and other biological activities. In food it is recognized as the natural colorant designated E163a.
Dulaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist, a type of injectable medicine used to treat type 2 diabetes and to lower cardiovascular risk. Marketed by Eli Lilly under the brand name Trulicity and approved in 2014, it is a long-acting drug given as a once-weekly injection under the skin. It mimics a natural gut hormone that prompts the pancreas to release insulin when blood sugar is high, while also curbing appetite. In addition to improving blood sugar control, it has been shown to reduce the risk of major cardiovascular events such as heart attack and stroke.
EGCG (epigallocatechin gallate) is the most abundant and most studied catechin in green tea, a flavonoid polyphenol that accounts for much of the leaf's reputation for health. It is a strong antioxidant and metabolic modulator that shows up in the research on fat oxidation, cardiovascular and metabolic health, inflammation, and longevity. Most of its effects are hormetic (a mild stress the body adapts to), and the honest catch is that isolated high-dose EGCG on an empty stomach carries a rare liver-injury signal, so it is best taken with food.
Empagliflozin is an oral medication of the sodium-glucose cotransporter-2 (SGLT2) inhibitor class, used to treat type 2 diabetes, heart failure, and chronic kidney disease. It acts in the kidneys, causing the body to pass excess glucose out in the urine, and in large trials it has reduced cardiovascular death and hospitalizations for heart failure. It is taken once daily and is sold under the brand name Jardiance.
Fenugreek (Trigonella foenum-graecum) is an annual legume whose aromatic seeds and leaves are used worldwide as a spice and in traditional medicine. Its seeds, which carry a maple-like aroma, are taken as a dietary supplement marketed for blood sugar, cholesterol, testosterone and milk production in nursing mothers. High-quality clinical evidence for most of these uses is still limited.
Leucine is an essential branched-chain amino acid that the body uses to build proteins but cannot make on its own. Along with valine and isoleucine it belongs to the branched-chain group, and it is best known for switching on the cellular machinery that drives muscle protein synthesis. It is obtained from protein-rich foods and is a common ingredient in sports and clinical nutrition supplements.
Liraglutide is an acylated glucagon-like peptide-1 (GLP-1) receptor agonist given by once-daily subcutaneous injection, marketed as Victoza for type 2 diabetes and as Saxenda at higher dose for weight management. By activating GLP-1 receptors it augments glucose-dependent insulin secretion with low hypoglycemia risk, and its weight-lowering effect is attributed mainly to central appetite suppression rather than the more transient slowing of gastric emptying, which is subject to desensitization. Beyond glycemic control, the LEADER cardiovascular outcomes trial showed that liraglutide reduced major adverse cardiovascular events and cardiovascular death in high-risk patients with type 2 diabetes, and further study demonstrated histological resolution of non-alcoholic steatohepatitis. These extra-pancreatic actions across the cardiovascular, hepatic, and central nervous systems have positioned it as a foundational agent in the incretin therapeutic class.
Mazdutide (IBI362, LY3305677) is an investigational once-weekly peptide that simultaneously activates the glucagon-like peptide-1 (GLP-1) and glucagon receptors, a dual-agonist design intended to combine appetite suppression and improved glycemic control from the GLP-1 arm with increased energy expenditure and hepatic lipid handling from the glucagon arm. In Chinese phase 3 obesity trials it produced substantial, dose-dependent weight loss, with the GLORY-2 study reporting roughly 16 percent mean body-weight reduction at the 9 mg dose, alongside favorable changes in blood pressure and lipids. In type 2 diabetes it lowered glycated hemoglobin and body weight more than the GLP-1 monotherapy dulaglutide, and it improved fatty liver and cardiometabolic markers. Gastrointestinal effects such as nausea, vomiting, and diarrhea are the most common adverse events, consistent with its incretin mechanism.
Nigella sativa is an annual flowering plant of the buttercup family (Ranunculaceae), native to parts of western Asia and southeastern Europe and best known for its small black seeds, sold under names such as black seed, black cumin, and kalonji. The seeds have served for millennia as a culinary spice and as a fixture of traditional medicine across the Middle East, North Africa, and South Asia. Their most studied constituent is thymoquinone, a compound concentrated in the seed's volatile oil. Laboratory work has documented antioxidant and anti-inflammatory activity, though high-quality clinical evidence that the seed or its oil treats human disease remains limited.
Nobiletin is a polymethoxylated flavone, a type of plant flavonoid distinguished by several methoxy groups attached to its ring structure. It occurs naturally in the peels of citrus fruits, being especially abundant in tangerines and related species. Laboratory and animal research has examined it for anti-inflammatory, metabolic, and neuroprotective activity, and more recently for its ability to influence the body's circadian clock. It is a dietary constituent and research compound rather than an approved medicine.
R-alpha-lipoic acid is the naturally occurring form of alpha-lipoic acid, a sulfur-containing compound that the body uses as an essential cofactor in energy metabolism and that also acts as an antioxidant. Alpha-lipoic acid exists as two mirror-image forms, and only the R version is made and used by living cells, whereas most synthetic supplements contain an equal mixture of the R and S forms. Sold as a dietary supplement and, in some countries, as a medicine for diabetic nerve pain, the R form is often promoted as the more biologically active and better absorbed of the two.
Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist, a class of drug that mimics a natural gut hormone to lower blood sugar and reduce appetite. Developed by Novo Nordisk, it is used to treat type 2 diabetes and, at higher doses, obesity and overweight, and it has been shown to lower the risk of major cardiovascular events. It is marketed as Ozempic and Rybelsus for diabetes and as Wegovy for weight management, given as a weekly injection or, in one form, an oral tablet.
Curcumin is a bright yellow polyphenol, the principal curcuminoid of turmeric, the spice ground from the rhizome of Curcuma longa in the ginger family. It has long been used as a food colouring and flavouring and is widely sold as a herbal supplement, but it is chemically unstable and very poorly absorbed by mouth. In medicinal chemistry it is regarded as a difficult, likely misleading lead compound, and despite extensive study no rigorous clinical trial has established it as an effective medical treatment [1][2].
Inositol is a naturally occurring sugar alcohol, most abundant as the isomer myo-inositol, that serves as a building block for cell membrane phospholipids and for intracellular signaling molecules. It was once grouped with the B vitamins as vitamin B8, but because the human body synthesizes it, inositol is not considered a true vitamin or an essential nutrient. It occurs in foods such as fruits, beans, grains, and nuts, and myo-inositol together with its isomer D-chiro-inositol has been studied for use in polycystic ovary syndrome and related metabolic conditions.
Vitamin D3 (cholecalciferol) is a fat-soluble secosteroid synthesized in the skin under ultraviolet B light and obtained from a few foods, becoming biologically active only after sequential hydroxylation in the liver and kidney to calcitriol (1,25-dihydroxyvitamin D). Beyond its classical control of calcium absorption and bone mineralization, calcitriol acts through the nuclear vitamin D receptor to regulate hundreds of target genes and to epigenetically program monocytes, macrophages and dendritic cells; immune cells can generate the active hormone locally to induce antimicrobial peptides such as cathelicidin and to trigger autophagy against intracellular pathogens including Mycobacterium tuberculosis. In the large VITAL randomized trial, several years of supplementation modestly reduced the incidence of autoimmune disease and of advanced or fatal cancer, while showing largely neutral effects on major cardiovascular events. Prolonged deficiency causes rickets in children and osteomalacia in adults, and the vitamin appears on the World Health Organization list of essential medicines.
Canagliflozin is an orally active sodium-glucose cotransporter-2 (SGLT2) inhibitor, marketed chiefly as Invokana, and in 2013 it became the first agent of its class approved in the United States for glycemic control in type 2 diabetes. It lowers blood glucose by promoting urinary glucose excretion in the kidney, and the landmark CANVAS and CREDENCE trials established that it also reduces major cardiovascular events, hospitalization for heart failure, and progression of diabetic kidney disease. Beyond its renal target, canagliflozin uniquely activates the cellular energy sensor AMP-activated protein kinase by mildly inhibiting mitochondrial complex I and raising intracellular AMP, a mechanism that other gliflozins show only weakly. This off-target activity has drawn attention in aging research, where the compound extended lifespan in genetically heterogeneous male mice and was later found to enhance immune clearance of senescent cells. Its recognized risks include the lower-limb amputation and fracture signals observed in the CANVAS Program.
Dapagliflozin is a prescription medication of the SGLT2 inhibitor, or gliflozin, class, sold under brand names such as Farxiga and Forxiga. One of the first drugs in its class, it is used to treat type 2 diabetes, chronic heart failure, and chronic kidney disease. It works in the kidney by blocking a transporter that reabsorbs glucose, so that more sugar is passed out in the urine, and it also produces benefits for the heart and kidneys that reach beyond blood sugar control. It is taken once daily by mouth.
Glimepiride and metformin is a fixed-dose combination medication used to treat type 2 diabetes mellitus, pairing two oral glucose-lowering drugs with complementary actions. Metformin is a biguanide that lowers blood sugar chiefly by reducing glucose production in the liver and improving insulin sensitivity, while glimepiride is a sulfonylurea that stimulates the pancreas to release more insulin. Combining them in a single tablet is intended to improve blood-sugar control and simplify treatment for people whose diabetes is not adequately managed by one agent alone.
Insulin aspart is a rapid-acting insulin analog used to control blood sugar in people with type 1 and type 2 diabetes. It is a laboratory-modified form of human insulin in which the amino acid proline at position B28 is replaced by aspartic acid, a change that makes the insulin absorb and act more quickly than regular human insulin. Developed by Novo Nordisk and sold under names such as NovoLog and NovoRapid, it is taken at mealtimes and is listed by the World Health Organization as an essential medicine.
Insulin glargine is a long-acting, or basal, insulin analog used to provide a steady background level of insulin in people with type 1 and type 2 diabetes. It is a modified human insulin engineered to dissolve slowly after injection, releasing insulin at a relatively flat rate over roughly a day so that a single daily dose can cover the body's baseline needs. First approved in 2000 and originally sold as Lantus, it is now available in several brands and biosimilars and appears on the World Health Organization list of essential medicines.
Biphasic human insulin 30/70 is a premixed insulin that combines a short-acting and an intermediate-acting insulin in a single fixed formulation, containing 30 percent soluble regular human insulin and 70 percent protamine-bound isophane (NPH) insulin. This blend delivers both a mealtime and a background insulin effect from one injection, which is why it is often used in type 2 diabetes to simplify treatment. It is a cloudy suspension given once or twice daily and is a long-established, widely used insulin preparation.
Regular insulin, also called soluble or short-acting insulin, is human insulin with its natural, unmodified amino acid sequence, used to lower blood sugar in diabetes. Given by injection before meals or into a vein in the hospital, it begins working in about half an hour and lasts several hours, and it is a standard treatment for diabetic emergencies such as ketoacidosis and for dangerously high blood potassium. Modern regular insulin is produced by recombinant DNA technology, and it appears on the World Health Organization list of essential medicines.
Isophane insulin, better known as NPH (Neutral Protamine Hagedorn) insulin, is an intermediate-acting insulin used to provide background blood-sugar control in type 1 and type 2 diabetes. It is regular human insulin combined with the protein protamine and zinc, which slows its absorption so that a single injection acts over much of a day. Developed in the 1930s and 1940s, it is a cloudy suspension that must be gently mixed before use and is listed by the World Health Organization as an essential medicine.
Insulin lispro is a rapid-acting insulin analog used at mealtimes to control blood sugar in type 1 and type 2 diabetes. It was the first insulin analog to be developed, created by swapping the order of two amino acids, lysine and proline, near the end of the insulin B chain so that the hormone is absorbed and acts faster than regular human insulin. Introduced by Eli Lilly in 1996 under the brand name Humalog, it is listed by the World Health Organization as an essential medicine.
Pioglitazone is an oral antidiabetic medicine of the thiazolidinedione class, used to improve blood sugar control in type 2 diabetes. Marketed as Actos, it works as an insulin sensitizer, activating a nuclear receptor called PPAR-gamma to make the body's tissues respond better to insulin. Effective at lowering blood glucose and with additional effects on fat and the liver, it is nonetheless used carefully because of side effects that include fluid retention, weight gain, and a debated association with bladder cancer.
Pioglitazone plus metformin is a fixed-dose combination tablet that unites two oral diabetes medicines with complementary actions: pioglitazone, a thiazolidinedione that makes tissues more sensitive to insulin, and metformin, a biguanide that mainly reduces the amount of glucose released by the liver. It is used to improve blood sugar control in adults with type 2 diabetes whose condition is not adequately managed on metformin alone. Combining the two drugs in a single pill is intended to lower blood sugar more fully while simplifying treatment, and it is marketed under names such as ACTOplus Met and Competact.
Sitagliptin is an oral antidiabetic drug of the dipeptidyl peptidase-4 (DPP-4) inhibitor class, often called a gliptin, used to improve blood-sugar control in adults with type 2 diabetes. It works by prolonging the action of the body's own incretin hormones, boosting insulin release and curbing glucagon after meals. Developed by Merck and approved in 2006 under the brand name Januvia, it is frequently combined with metformin.
Voglibose is an oral antidiabetic medication of the alpha-glucosidase inhibitor class, used to control the rise in blood glucose that follows meals in people with type 2 diabetes. It works within the small intestine by slowing the digestion of complex carbohydrates, which blunts the post-meal glucose peak rather than stimulating insulin. Developed in Japan and introduced there in the 1990s, it is used mainly in parts of Asia and belongs to the same class as acarbose and miglitol.
Survodutide is an investigational once-weekly glucagon receptor and GLP-1 receptor dual agonist positioned at the frontier of next-generation metabolic therapeutics. By engaging two complementary pathways, it pairs powerful appetite suppression with increased energy expenditure to drive substantial weight reduction and striking improvements in liver health. In phase 2 and phase 3 trials it delivered double-digit body weight loss and reversed steatohepatitis in a majority of treated participants, marking it as one of the most closely watched dual agonists in development.
Metformin is an oral antidiabetic medication of the biguanide class and the first-line drug for type 2 diabetes. Derived originally from a compound in the French lilac plant, it lowers blood sugar chiefly by reducing the amount of glucose the liver releases, without causing the weight gain or low blood sugar seen with some other agents. Beyond diabetes it is used in polycystic ovary syndrome and prediabetes, and its apparent effects on metabolism and aging have made it a subject of ongoing longevity research.
MOTS-c is a mitochondrial-derived peptide that acts as one of the body's own regulators of metabolism, energy, and healthy aging. Encoded inside the mitochondrial genome and released during exercise, it switches on the master energy sensor AMPK to improve insulin sensitivity, glucose handling, and physical performance. Backed by a fast-growing body of research from its discovery at USC, it sits at the leading edge of longevity and metabolic science.
Telmisartan is an orally active angiotensin II receptor blocker (ARB) of the benzimidazole class, used mainly to treat high blood pressure and to lower cardiovascular risk by blocking the angiotensin II type 1 (AT1) receptor. Unusually for its class it also behaves as a partial agonist of the nuclear receptor PPAR-gamma, the same target as the diabetes glitazones, which underlies its interest in metabolic disease; it also has the longest plasma half-life and highest lipophilicity of the marketed ARBs, giving persistent blood-pressure control and central nervous system penetration that has prompted study of cognitive and neuroprotective effects. It is given once daily.
Adiponectin is a protein hormone secreted mainly by fat cells that helps regulate blood sugar and the breakdown of fatty acids. Encoded by the ADIPOQ gene, it is one of the most abundant hormones in human blood and improves the body's sensitivity to insulin while exerting anti-inflammatory effects. Unusually for a fat-derived hormone, its levels tend to fall rather than rise with obesity, and low levels are linked to type 2 diabetes and metabolic disease.
Akkermansia muciniphila is a common bacterium of the human gut that lives in the protective mucus layer of the intestine, where it feeds on mucin. Discovered in 2004, it typically makes up a few percent of the gut microbes in healthy people, and its abundance tends to be lower in obesity and type 2 diabetes. It has drawn intense research interest as a next-generation probiotic, with early human studies suggesting that supplementing it may improve markers of metabolic health.
Albiglutide is an injectable glucagon-like peptide-1 (GLP-1) receptor agonist that was used to treat type 2 diabetes. Given once weekly under the brand names Tanzeum and Eperzan, it mimics the natural incretin hormone GLP-1 to lower blood sugar. Developed by GlaxoSmithKline, it was approved in 2014 but withdrawn from the market worldwide in 2018 for commercial reasons rather than safety concerns.
Aloe vera is a succulent plant of the genus Aloe (family Asphodelaceae) whose fleshy leaves yield two distinct materials: a clear inner gel and a bitter yellow latex. The inner gel is used widely in topical skin and wound products, in cosmetics, and as an ingredient in beverages and foods, while the latex has historically served as a stimulant laxative. Evidence is strongest for topical use on minor burns and skin healing; oral uses, including effects on blood glucose, are studied but less consistent.
Amylase is a digestive enzyme that catalyzes the hydrolysis of starch into simpler sugars such as maltose and glucose. It belongs to the glycoside hydrolase family and is produced chiefly by the salivary glands and the pancreas in humans, where it begins the breakdown of dietary carbohydrate. Related forms are made by plants, fungi, and bacteria, and the enzyme is widely used in food processing, brewing, and laboratory work.
Ashitaba is the common name for Angelica keiskei, a perennial flowering plant in the carrot family (Apiaceae) native to the Pacific coast of Japan. Its Japanese name means "tomorrow's leaf," a reference to how quickly it regrows after being cut. The plant is eaten as a vegetable and used in Japanese folk medicine, and its yellow sap is notable for containing distinctive chalcones, chiefly xanthoangelol and 4-hydroxyderricin, which are the focus of most laboratory research.
Banaba leaf extract is a botanical extract from the leaves of Lagerstroemia speciosa, a flowering tree of the family Lythraceae native to tropical Asia, also known as giant crepe-myrtle or pride of India. Long used as a leaf tea in Southeast Asian folk medicine for lowering blood sugar, the extract is valued for two main constituents, the triterpene corosolic acid and a group of ellagitannins. It is marketed as a dietary supplement for blood-sugar and metabolic support, with most supporting evidence coming from animal studies and small human trials.
Bitter melon extract is a herbal preparation derived from Momordica charantia, a tropical and subtropical vine of the gourd family (Cucurbitaceae) whose warty, intensely bitter fruit is both a vegetable and a traditional medicine. Long used in Asian, African, and Caribbean cooking and folk remedies, the plant and its extracts have been studied mainly for a possible blood-sugar-lowering effect in type 2 diabetes [1]. Clinical evidence for this use is mixed and generally of low quality, with some trials and analyses suggesting a modest benefit and others finding no clear effect [2][3]. It is sold as a dietary supplement in the form of capsules, powders, teas, and juices.
CagriSema is an investigational fixed-dose combination medicine that pairs cagrilintide, a long-acting amylin analogue, with semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist. Developed by Novo Nordisk and given as a once-weekly subcutaneous injection, it is being studied as a treatment for obesity and type 2 diabetes. In late-stage trials the combination produced substantial weight loss and improved blood-sugar control, and as of 2026 it remains under regulatory review rather than approved.
Chlorogenic acid is a natural polyphenol, formed as an ester of caffeic acid and quinic acid, that is found in many plants and is especially abundant in coffee [1][2]. Despite its name it contains no chlorine; the term refers to the light green tint it forms when oxidized [1]. It is one of the main phenolic compounds in the human diet, obtained from coffee, fruits, and vegetables, and standardized green coffee extracts rich in it are sold as supplements for weight and metabolic health [1][3]. Laboratory work points to antioxidant activity, and some clinical studies suggest modest effects on blood pressure and metabolism, but the overall evidence remains preliminary [1][3][4].
Cinnamon extract is a concentrated, standardized preparation made from the bark of Cinnamomum trees, intended to deliver the spice's active compounds in supplement form. It is used mainly for blood sugar and metabolic support, and depending on the extraction method it may concentrate the water-soluble polyphenols while reducing the fat-soluble compound coumarin. Clinical results for glucose control are modest and inconsistent.
CinSulin is a brand of water-extracted cinnamon supplement marketed for blood sugar support. It is produced by steeping cinnamon bark in water to concentrate the water-soluble compounds believed to influence glucose metabolism while leaving behind most of the fat-soluble coumarin. Small trials of this style of aqueous cinnamon extract have reported modest reductions in fasting blood glucose, although the broader evidence for cinnamon in diabetes remains mixed.
D-chiro-inositol is a stereoisomer of inositol, a naturally occurring sugar alcohol, and it functions as part of the signaling system through which insulin regulates blood glucose. In the body it is made from the more abundant myo-inositol by an insulin-dependent enzyme, and the balance between the two isomers is finely tuned and tissue-specific. It has been studied and used, often alongside myo-inositol, as a supplement for insulin resistance and polycystic ovary syndrome (PCOS).
E-6837 is a selective, high-affinity serotonin 5-HT6 receptor ligand developed at Laboratorios Dr. Esteve that behaves as a partial agonist at the rat receptor and a full agonist at the constitutively active human receptor. Unlike the cognition-focused members of its class, E-6837 is best known for a metabolic action: in diet-induced obese rats, chronic dosing produced sustained hypophagia and weight loss with an improved metabolic profile. Its weight-loss efficacy exceeded that of the reference drug sibutramine while causing less rebound weight regain. It remains a preclinical compound illustrating the appetite-regulating role of central 5-HT6 signaling.
Exenatide is a glucagon-like peptide-1 (GLP-1) receptor agonist, an injectable medication used to improve blood sugar control in type 2 diabetes. It is a synthetic version of exendin-4, a peptide first identified in the saliva of the Gila monster, and is sold under the brand names Byetta and Bydureon. By mimicking the gut hormone GLP-1, it prompts insulin release when glucose is high while curbing appetite and slowing digestion.
Fucoxanthin is a natural orange-brown pigment of the carotenoid family, found in brown seaweeds and in the microscopic algae called diatoms. In these organisms it is a light-harvesting pigment, capturing light energy for photosynthesis and giving brown algae their characteristic colour. It has been studied for a variety of possible health effects, most notably antioxidant activity and a role in fat metabolism, and it is sold as a dietary supplement made from brown seaweed. Its usefulness in people is limited by its low absorption from the gut.
Genistein is a naturally occurring isoflavone, a type of plant polyphenol that behaves as a phytoestrogen. It is found chiefly in soybeans and other legumes and was first isolated in 1899 from dyer's broom, the plant from which it takes its name. Because its structure resembles the hormone estradiol, it can interact with estrogen receptors, and it is also a well-studied inhibitor of tyrosine kinase enzymes [1][2].
Ginsenosides are a class of natural steroid glycosides and triterpene saponins found almost exclusively in plants of the genus Panax, the source of ginseng. They are regarded as the principal active constituents behind ginseng's biological effects, and more than a hundred distinct ginsenosides have been characterized. Structurally most belong to the dammarane family and are divided into protopanaxadiol and protopanaxatriol types, with individual members such as Rb1, Rg1, and Re studied for antioxidant, anti-inflammatory, and neuroprotective activities.
Gymnema sylvestre is a woody climbing plant in the family Apocynaceae, native to tropical parts of Asia, Africa, and Australia, and long used in Ayurvedic medicine. Its Hindi name gurmar, meaning "sugar destroyer," points to the plant's best-documented property: chewing the leaves temporarily blunts the perception of sweetness. The leaves contain a group of triterpenoid saponins called gymnemic acids, which are the focus of research into taste modulation and blood-sugar control.
Horny goat weed is the common name for Epimedium, a genus of flowering plants in the barberry family, Berberidaceae, most species of which are native to China. Known in Chinese medicine as yin yang huo, it has been used for centuries as a tonic and reputed aphrodisiac, as well as for fatigue and bone and joint complaints. Its principal active compound is the flavonoid icariin, which has been studied for effects on erectile function and bone.
Insulin-like growth factor 1 (IGF-1), also called somatomedin C, is a peptide hormone that is structurally close to insulin and serves as the principal mediator of growth hormone action. Produced chiefly by the liver but also locally in tissues, it signals through the IGF-1 receptor to drive cell proliferation, differentiation, and protein synthesis, and it feeds back on the hypothalamus and pituitary to help regulate the growth hormone axis. A notable feature is the alternative splicing of the IGF-1 gene in skeletal muscle to yield mechano growth factor, a variant rapidly induced by mechanical loading or injury that is associated with satellite (stem) cell activation and repair, though its distinct peptide activity remains debated. A recombinant form, mecasermin, is an approved therapy for children with severe primary IGF-1 deficiency, and the hormone remains a central focus in research on aging, longevity, neuroprotection, and cancer risk.
INT131 (also written INT-131, formerly T131 and AMG131) is an experimental oral drug for type 2 diabetes, developed by InteKrin Therapeutics as a selective PPAR-gamma modulator (SPPARM). Unlike the older thiazolidinedione insulin sensitizers, it only partially activates the PPAR-gamma receptor, a design intended to keep the blood-sugar benefits of that drug class while avoiding side effects such as weight gain and fluid retention. It reached mid-stage clinical trials but is not an approved medicine.
Jiaogulan is a climbing vine in the gourd family, Cucurbitaceae, whose scientific name is Gynostemma pentaphyllum. Native to parts of South and East Asia, its leaves are brewed as a herbal tea and used in traditional Chinese and other folk medicine, where it has earned nicknames such as southern ginseng and five-leaf ginseng [1]. Its notable constituents are saponins called gypenosides, some of which are structurally close to the ginsenosides of true ginseng [1][2].
Lactase is a digestive enzyme, a type of β-galactosidase, that breaks the milk sugar lactose into the simpler sugars glucose and galactose so they can be absorbed. In mammals it is produced by cells lining the small intestine and is most active in infancy. In many people its activity falls after weaning, leading to lactose intolerance, and the enzyme is manufactured commercially as a supplement and used to make lactose-free dairy foods.
Lipase is any of a broad class of enzymes that break down fats by splitting triglycerides into fatty acids and glycerol. In the human body, lipases produced mainly by the pancreas carry out much of the digestion of dietary fat, and the enzyme occurs throughout the living world in animals, plants, and microbes. Beyond digestion, blood lipase levels are used to diagnose pancreatitis, and lipase preparations are taken as digestive aids and used widely in industry.
M617 is a synthetic chimeric galanin analog that acts as a galanin receptor 1 preferring agonist and is used as a subtype-selective research tool. Built from the galanin N-terminus fused to a bradykinin-derived segment, it engages GalR1 to produce antinociception in central pain circuits and to improve glucose handling in diabetic rodents by enhancing insulin signaling and glucose-transporter activity in muscle. As one of the more GalR1-selective agonists available, M617 has been valuable for isolating GalR1-specific functions in pain and metabolism. It is a preclinical peptide with no clinical use.
Maitake (Grifola frondosa) is an edible and medicinal mushroom native to temperate forests of East Asia and North America, where it grows in large clustered fruiting bodies at the base of trees. It is valued both as a culinary mushroom and as a source of bioactive polysaccharides, especially beta-glucans, that have been studied for immune-modulating and antitumor effects [1][3]. A partially purified extract known as maitake D-fraction has been the focus of much of the medicinal research [2][3].
Myricetin is a naturally occurring flavonoid of the flavonol subclass, a plant pigment found in many fruits, vegetables, berries, teas and wines. Closely related in structure to quercetin, it is studied chiefly for antioxidant and anti-inflammatory activity and a broad range of other effects observed in the laboratory. It is not a drug but a dietary compound, consumed in ordinary foods and sold as a supplement.
NAX-5055, also known as Gal-B2, is a systemically active, metabolically stable galanin analog engineered to cross the blood-brain barrier by combining cationization with position-specific lipidization. It is a GalR1-preferring agonist with low-nanomolar receptor affinity and potent anticonvulsant activity in multiple rodent seizure models, including models of pharmacoresistant epilepsy. It was positioned as a potential first-in-class antiepileptic neuropeptide therapeutic. NAX-5055 also engages peripheral GalR1 to raise blood glucose, which shaped subsequent development toward GalR2-preferring successors.
Oleuropein is a phenolic compound of the secoiridoid class and one of the main polyphenols of the olive tree. It is found in olive leaves, in olives, and in smaller amounts in olive oil, and it is chiefly responsible for the bitter taste of unprocessed olives. Structurally it combines the antioxidant hydroxytyrosol with elenolic acid and a sugar unit. It has been studied for a range of biological activities, including antioxidant, anti-inflammatory, and cardiovascular effects, and is regarded as a dietary and research compound rather than an approved medicine.
Oxaloacetate is a four-carbon organic acid that occupies a central place in cellular metabolism. Best known as a key intermediate of the citric acid cycle, also called the Krebs cycle, it combines with acetyl-CoA to form citrate at the start of the cycle and also feeds gluconeogenesis, the making of new glucose, and the synthesis of several amino acids. Beyond its metabolic role, a stabilized supplement form has been studied for effects such as lowering blood glutamate levels reaching the brain and mimicking aspects of calorie restriction, though these uses remain investigational.
Phloretin is a dihydrochalcone, a naturally occurring plant phenol found in apples, apple tree leaves, and the Manchurian apricot. It is the aglycone of phlorizin, meaning the sugar-free core of that better-known apple compound, and it is studied chiefly as an antioxidant and as an inhibitor of glucose transport across cell membranes. Phloretin appears as an ingredient in some skincare products and is a subject of laboratory research, but it is not an approved medicine.
Piceatannol is a stilbenoid, a naturally occurring plant polyphenol closely related to resveratrol, from which it differs by a single extra hydroxyl group. It is found in grapes, red wine, passion fruit seeds, and other plants, and the body can also form it from resveratrol. Studied mainly in the laboratory, it has drawn interest for antioxidant, anti-inflammatory, and anticancer activities and as an inhibitor of the enzyme Syk kinase, but it remains a research compound rather than an approved medicine.
Piperine is the principal pungent alkaloid of black pepper (Piper nigrum) and long pepper (Piper longum), responsible for the spice's biting taste through activation of the capsaicin receptor TRPV1; structural studies show it occupies the same ligand-binding pocket as capsaicin but adopts a distinct binding pose, acting as a comparatively weak agonist. Its most exploited pharmacological property is bioenhancement, since it inhibits hepatic and intestinal glucuronidation as well as cytochrome P450 3A4 and the efflux transporter P-glycoprotein, thereby slowing first-pass metabolism and raising systemic exposure of co-administered compounds; the classic demonstration reported a roughly 2000 percent increase in curcumin bioavailability in humans. Piperine also inhibits monoamine oxidase and has shown antidepressant-like, anticonvulsant, and neuroprotective activity in animal models, with anti-seizure effects mediated through TRPV1. It is widely marketed as a standardized extract for use alongside poorly absorbed nutraceuticals.
Pramlintide is a synthetic analogue of amylin, a peptide hormone released by the pancreas alongside insulin after meals. Given by injection at mealtimes, it is used together with insulin to improve blood-sugar control in people with type 1 or type 2 diabetes, chiefly by blunting the sharp rise in glucose that follows eating. Marketed as Symlin, it was approved by the United States FDA in 2005 and was the first new agent for lowering blood sugar in type 1 diabetes since insulin itself.
Rehmannia (Rehmannia glutinosa), known in Chinese as dihuang, is a flowering plant traditionally counted among the fundamental herbs of Chinese medicine. Its root, used fresh, dried, or steam-processed, is a staple of many classical herbal formulas. Modern chemical work has identified iridoid glycosides such as catalpol among its main constituents.
Rhoifolin is a naturally occurring flavone glycoside, chemically apigenin 7-O-neohesperidoside, belonging to the flavonoid group of plant compounds. It was first isolated from the leaves of Rhus succedanea, which gave it its name, and is found in a range of plants including citrus species. Laboratory research has reported antioxidant, anti-inflammatory, and other bioactivities, though it has not been developed into a medicine.
The first CB1 cannabinoid-receptor blocker; a withdrawn anti-obesity drug (Acomplia) that curbed appetite and cleaned up metabolic markers, but was pulled worldwide for serious psychiatric risk.
Saxagliptin (brand name Onglyza) is a once-daily oral DPP-4 inhibitor, a 'gliptin,' approved for type 2 diabetes. It contains an adamantyl group in its structure. By blocking the enzyme dipeptidyl peptidase-4 (DPP-4), it lets the gut incretin hormones GLP-1 and GIP last longer; those hormones prompt the pancreas to release insulin when blood sugar is high and to cut back glucagon, so blood sugar falls in a glucose-dependent way. It lowers HbA1c with a low risk of hypoglycemia and is generally weight-neutral.
Somatostatin, also called growth hormone-inhibiting hormone, is a cyclic peptide that acts as a widespread inhibitory signal, dampening the release of growth hormone, insulin, glucagon, and gastrointestinal secretions. It operates through five G-protein-coupled receptor subtypes (SSTR1 to SSTR5) that couple mainly to inhibition of adenylate cyclase and cyclic AMP, with additional signaling through ion channels and downstream kinases; notably, some subtypes such as SSTR3 exert constitutive, ligand-independent suppression of growth hormone synthesis. Its very short half-life in the circulation spurred the development of longer-acting analogues such as octreotide and lanreotide, which selectively target SSTR2 and SSTR5 to treat acromegaly and neuroendocrine tumors. The same gene also yields the related peptide neuronostatin, underscoring the system's role as a finely tuned regulator of endocrine and metabolic tone.
Spexin, also called neuropeptide Q, is a small 14-amino-acid peptide discovered by bioinformatics and later shown to be an endogenous ligand of galanin receptors 2 and 3, part of a shared spexin, galanin, and kisspeptin family. It is broadly expressed across endocrine and nervous tissue and functions as a regulatory adipokine, with circulating levels reduced in obesity and linked to metabolic and inflammatory markers. Spexin also stimulates gastrointestinal motility through galanin receptor 2 and has been associated with appetite, cardiovascular, reproductive, and mood-related functions. It is an endogenous peptide of growing translational interest.
Trigonelline is a plant alkaloid, the N-methylated betaine of niacin (vitamin B3), that exists as a zwitterion. It is found in many foods, notably fenugreek seeds, from which it takes its name, and coffee beans, where roasting breaks it down into niacin and aroma compounds. Trigonelline has drawn research interest for effects on blood sugar and, more recently, as a natural precursor that can raise cellular NAD levels [1][2].
Vanadium is a chemical element and transition metal (symbol V) that is present in the diet in trace amounts. It is not established as an essential nutrient for humans, and interest in it as a supplement centers on vanadium compounds such as vanadyl sulfate, which imitate some actions of insulin in laboratory studies. Marketed forms have been promoted for blood-sugar control and, among bodybuilders, for muscle gains, but human evidence for these uses is weak and all vanadium compounds are considered potentially toxic at higher intakes.
Vildagliptin (brand name Galvus) is an oral DPP-4 inhibitor, a 'gliptin,' used for type 2 diabetes; its structure includes an adamantyl group. Like other gliptins it blocks the enzyme DPP-4 so the gut incretin hormones GLP-1 and GIP persist longer, improving the pancreas's insulin and glucagon responses to glucose and lowering blood sugar. It reduces HbA1c with little effect on body weight and a low risk of hypoglycemia. It is marketed in many countries but is not FDA-approved in the United States.
Xanthohumol is a prenylated chalcone, a type of flavonoid, and the principal such compound in the female flowers of the hop plant (Humulus lupulus). Because hops are used to brew beer, xanthohumol is a natural constituent of beer, usually at very low concentrations. It has been widely studied in the laboratory for antioxidant, anti-inflammatory, and anticancer activities, and it is sold as a dietary supplement rather than an approved medicine.
