Magtein® is a patented form of magnesium L-threonate with a fixed composition and standardized quantity.
L-threonate is a compound formed from vitamin C (ascorbic acid) and is used to bind magnesium.
The difference is in the substance to which magnesium is bound. In the case of L-threonate, that's a vitamin C derivative, while other forms are bound to, for example, citric acid (citrate) or amino acids (bisglycinate).
Magnesium is found in foods such as green leafy vegetables, nuts, seeds, whole grains, and cocoa.
Elemental magnesium is the amount of pure magnesium within a compound, separate from the substance it is bound to.
No, magnesium L-threonate as a compound does not naturally occur in foods. It is synthetically bound in supplements.
Intake with a light meal, such as at dinner, is recommended, especially if you have a sensitive stomach.
