Magnesium threonate (magnesium L-threonate) capsules

Magnesium threonate, spelled T-H-R-E-O-N-A-T-E and also called magnesium L-threonate, is one of the many forms of magnesium sold as a supplement. As with any supplement, the basics come first: light-viewing behavior, then nutrition, then activity, and only then supplements, after checking with your doctor. The capsules here are magnesium L-threonate made with Magtein, a branded form of the ingredient.
