Magnesium acetate is the magnesium salt of acetic acid, with the formula Mg(CH3COO)2. It forms white, water-soluble, moisture-absorbing crystals and is used as a food additive, a laboratory buffer, and a source of magnesium. As a dietary ingredient its role is simply to deliver magnesium, an essential mineral, in a soluble form.
Magnesium chloride is a highly soluble inorganic salt of the essential mineral magnesium, made of one magnesium ion and two chloride ions (MgCl2). It is used as a dietary supplement to raise or maintain magnesium status, and it is also the magnesium form behind topical "magnesium oil," a concentrated MgCl2 solution applied to the skin [1][5]. Because it dissolves and ionizes fully, the chloride form is absorbed on par with other soluble magnesium salts and better than magnesium oxide, though the fraction taken up is still modest like every magnesium supplement [1].
S107, also called ARM036, is a member of the Rycal class of small molecules that stabilize ryanodine receptors (RyR), the calcium release channels of the sarcoplasmic and endoplasmic reticulum. By preserving the binding of the stabilizing subunit calstabin to leaky RyR channels, S107 reduces pathological intracellular calcium leak implicated in heart failure and arrhythmia [1][2], muscle fatigue and reduced exercise capacity [3], muscular dystrophy [4], and stress-related cognitive dysfunction [5].
