Magnesium lysinate glycinate is double bonded to both lysine and glycine, which the body easily recognizes and absorbs. Because it’s 100% chelated, it is one of the most absorbable forms of magnesium with a 90% absorbability rate (compared to magnesium oxide, which is less than 5%.) Both lysine and glycine are amino acids that help support sleep, a calm mood, and focus.
