Magnesium Supplements: a simple buying guide

Magnesium supplements in capsules, tablets, powders, gummies, sprays, bath flakes and drinks, in forms such as magnesium glycinate (bisglycinate), citrate, malate, taurate, L-threonate and oxide, plus combinations such as ZMA and magnesium with B6. Brands include NOW Foods, BetterYou, Osavi, Doctor's Best, Life Extension, Jarrow Formulas, Natural Vitality, Apollo's Hegemony, Skill Nutrition and more.

Magnesium contributes to a reduction of tiredness and fatigue, to normal muscle function, to electrolyte balance and to normal functioning of the nervous system. The form affects how much actual magnesium each serving provides: labels usually list the elemental magnesium per serving, which is the number to compare. Glycinate and citrate are popular everyday forms; citrate in higher amounts can have a laxative effect. Topical sprays and bath flakes are used on the skin rather than swallowed. Excessive consumption of magnesium supplements may have a laxative effect, so follow the label directions. Our magnesium guide compares the forms.
