Magnesium
What it is
Magnesium is an essential mineral involved in many enzyme reactions, including those related to muscle and nerve function and energy metabolism. Foods such as legumes, nuts, seeds, whole grains, and leafy vegetables contribute to intake. Supplements pair magnesium with different compounds; the compound weight is not the same as the amount of elemental magnesium.
Why people look for it
Sleep, dietary adequacy, and supplement format are common reasons for looking it up. This page provides orientation; the sleep article and comparisons address those more specific decisions.
What research generally looks at
Research considers magnesium status, absorption, and outcomes such as sleep measures. Studies differ in population and preparation, so the existence of an essential physiological role is not proof that extra magnesium improves sleep.
Important context
Magnesium glycinate is not interchangeable with isolated glycine used in sleep trials. Kidney function, medicines, and total supplemental intake can change suitability. Compare labels by elemental magnesium, not by the number of magnesium forms advertised.

Advanced Mitochondrial Formula Review: Many Ingredients, Which Dose Matches?This two-capsule formula discloses individual amounts, including CoQ10 50 mg, acetyl L-carnitine 190 mg and PQQ disodium salt 5 mg. That supports a label audit, but several ingredient studies use different doses or populations and do not establish an energy benefit from this combination.

Yu Sleep Review: A Known Melatonin Dose Inside an Undisclosed BlendYu Sleep’s owner-confirmed formula provides 0.9 mg melatonin in a 2 mL serving, plus a 637 mg blend whose seven ingredient amounts are hidden. Its liquid format is a preference feature; the disclosure cannot establish how much magnesium, theanine, apigenin, GABA or other blend constituents a serving supplies.

CircO2 Review: What the 420 mg Blend Reveals—and HidesCircO2’s lozenge discloses vitamin C 100 mg, B12 1,000 mcg and a 420 mg total blend. It does not disclose individual beetroot, hawthorn, citrulline or sodium-nitrite amounts, nitrate content, or a separate elemental-magnesium dose. That prevents the dose comparisons central to its nitric-oxide positioning.

Magnesium Breakthrough Review: The 500 mg Decision Before the Seven FormsThe regular Magnesium Breakthrough label supplies 500 mg elemental magnesium per two capsules, above the U.S. adult supplemental/medication UL of 350 mg/day. The seven forms are named but their individual contributions are hidden. Dose suitability comes before paying for form variety, whose clinical superiority remains unverified.
