Overview
Magnesium + malic acid — favored for daytime energy and fibromyalgia-related fatigue.
- Whole foods (leafy greens, legumes, nuts, seeds, seafood, animal proteins)
- Fortified foods such as cereals, breads, plant milks, and table salt
- Mineral supplements as chelates, citrates, glycinates, or inorganic salts
- Chelated form (glycinate, bisglycinate, citrate, malate)
- Inorganic salt (oxide, sulfate, chloride)
- Liquid ionic solution
- Topical or transdermal preparation
Forms & variants of Magnesium
Different chemical forms of Magnesium behave differently. Browse each form's mechanism, bioavailability, and best-use context.
Essential cofactor in 300+ enzymatic reactions, from ATP production to muscle relaxation.
Chelated magnesium bound to glycine — best-tolerated form for sleep, calm, and muscle relaxation.
Highly bioavailable magnesium with a mild osmotic laxative effect — useful for constipation and repletion.
Magnesium bound to L-threonic acid — the only form shown to meaningfully raise brain magnesium.
Magnesium + taurine — gentle on the gut with cardiovascular and glycemic synergies.
Cheapest magnesium salt — poor absorption (~4%) but useful as a laxative or antacid.
Topical and oral magnesium with good absorption — commonly used in 'magnesium oil' sprays.
Magnesium + orotic acid — studied specifically in heart failure and athletic populations.
Reference IV form used in eclampsia and acute asthma.
Brain-penetrant Mg form combined with taurate for mood.
Mechanism of action
Malate enters the Krebs cycle, supporting mitochondrial ATP production; Mg is the cofactor for ATP itself.
- · TCA cycle (malate–aspartate shuttle)
- · Mg-ATP
Effects on the body
Organ system effects
Magnesium Malate supports mitochondrial ATP production and fatigue resistance.
