Magnesium vs. Magnesium Glycinate: What's the Difference?

Edited by Harlon Moss || By Janet White || Published on December 10, 2023
Magnesium is a chemical element essential for human health, while magnesium glycinate is a magnesium salt used for better absorption and tolerance.

Key Differences

Magnesium is a chemical element, represented by the symbol Mg, essential in human biology for various physiological functions. Magnesium glycinate, however, is a compound formed by combining magnesium with glycine, an amino acid, enhancing magnesium's bioavailability and absorption.
In its elemental form, magnesium is involved in over 300 biochemical reactions in the body, including energy production and protein synthesis. Magnesium glycinate is specifically designed to be more easily absorbed by the body and is often used as a dietary supplement.
Magnesium, in its various forms, is crucial for muscle and nerve function, blood glucose control, and bone health. Magnesium glycinate, by being bound to glycine, is less likely to cause gastrointestinal issues, a common side effect with other magnesium supplements.
The body requires magnesium in significant amounts, which is usually obtained through diet. Magnesium glycinate is often recommended for individuals with magnesium deficiency or for those who need a supplement that is gentle on the stomach.
Magnesium is available in many foods, such as nuts, seeds, and green leafy vegetables, while magnesium glycinate is specifically formulated for supplemental use, often recommended for its calming and relaxing effects on the body and mind.

A light, silvery-white, moderately hard metallic element that in ribbon or powder form burns with a brilliant white flame. Obtained chiefly from magnesite, dolomite, and bodies of salt water, it is used in structural alloys, pyrotechnics, flash photography, and incendiary bombs. Atomic number 12; atomic weight 24.305; melting point 650°C; boiling point 1,090°C; specific gravity 1.738 (at 20°C); valence 2. See Periodic Table.


The chemical element (symbol Mg) with an atomic number of 12. It is a light, easily flammable, silvery-white alkaline earth metal.


A light silver-white metallic element of atomic number 12, malleable and ductile, quite permanent in dry air but tarnishing in moist air. It burns, forming (the oxide) magnesia, with the production of a blinding light (the so-called magnesium light) which is used in signaling, in pyrotechny, or in photography where a strong actinic illuminant is required. Its compounds occur abundantly, as in dolomite, talc, meerschaum, etc. Symbol Mg. Atomic weight, 24.305. Specific gravity, 1.75.


A light silver-white ductile bivalent metallic element; in pure form it burns with brilliant white flame; occurs naturally only in combination (as in magnesite and dolomite and carnallite and spinel and olivine)
