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.

Overview
Vanadium is a hard, silvery-grey transition metal with atomic number 23 that can exist in several oxidation states, a property central to both its chemistry and its biological behavior [3]. People take in only small amounts from food, and it is poorly absorbed from the gut, so systemic exposure from a normal diet is low [1]. Regulatory bodies have not confirmed vanadium as an essential nutrient for humans, and no recommended intake has been set, although a tolerable upper limit has been defined [1].
Vanadium plays clearer roles in some non-human organisms; certain marine algae use vanadium-dependent enzymes, and sea squirts and some mushrooms accumulate the metal to striking concentrations for reasons that remain unclear [3]. In mammals its physiological role is uncertain, though experimental deficiency has been linked to impaired growth in animals [3]. Much of the scientific interest stems from the observation that vanadium compounds can imitate or amplify the effects of insulin in cells and animals [3].
As a dietary supplement, vanadium is sold mainly in the forms vanadyl sulfate and sodium metavanadate, and researchers have also studied organic complexes such as bis(maltolato)oxovanadium [3]. It has been promoted for improving blood-sugar control in type 2 diabetes and, in the fitness world, for building muscle, yet the supporting human evidence is limited and generally of poor quality [1]. A systematic review of oral vanadium for glycemic control concluded that no adequately rigorous trials existed and that routine use for this purpose could not be recommended [1]. Animal reviews report effects on glucose and blood-lipid measures but likewise call for well-designed clinical trials before any therapeutic use [2][3].
Safety is a significant concern, because vanadium compounds are generally regarded as toxic, and the higher-dose supplementation used in trials has often caused gastrointestinal side effects [1]. Occupational exposure to vanadium dust and fumes mainly affects the respiratory tract, and the metal has been examined for a range of other toxic effects [3]. In the United States vanadium is sold as a dietary supplement rather than as an approved medicine, and its promotion for diabetes or athletic performance is not supported by strong clinical evidence [1][3].
Mechanism
Interest in vanadium's biological activity rests largely on its ability to act as an -mimetic, meaning it can reproduce or strengthen several of the cellular effects of insulin [3]. At the molecular level, vanadium compounds inhibit protein tyrosine phosphatases, including protein tyrosine phosphatase 1B, an enzyme that normally switches off -receptor signaling; by blocking this off switch, vanadium prolongs activation of the insulin signaling cascade and can promote glucose uptake through pathways involving the glucose transporter GLUT4 [3].
Through related actions it has produced hypoglycemic and lipid-lowering effects in diabetic animal models [2][3]. The metal's several oxidation states, chiefly the vanadyl and vanadate forms, shape how it is absorbed, distributed and how it acts in the body [3]. These same reactive properties also underlie its toxicity, so the amounts needed for metabolic effects in studies have often approached or exceeded doses considered safe, and a clear clinical benefit in humans remains unproven [1][3].

Safetyrisks and cautions, not medical advice
At supplement doses vanadium commonly causes GI upset, cramping, and diarrhea; higher intakes can cause green tongue and are linked to kidney and other organ accumulation. It has a narrow window between any possible benefit and toxicity, so megadosing is a bad idea. People with kidney issues or on diabetes medication should stay away without medical supervision.

Interesting mineral, not something actually worth supplementing; the risk-to-payoff just is not there for most people.

FAQ
Does vanadium give you energy?
There is no real evidence for that. Its studied effect is on blood sugar, not on subjective energy.
Is vanadium safe to take daily?
The doses used in glucose studies are high enough that chronic daily use raises toxicity concerns. Not something to do without a doctor.
Is it an essential nutrient?
Its essentiality in humans is not firmly established. You get trace amounts from food regardless.
Can it replace diabetes medication?
No. The human effect is weak and it is not an approved treatment.
