Overview

This chelated magnesium glycinate capsule delivers 500mg per serving, positioned for sleep, muscle, bone and heart support. The 120-capsule bottle is vegan and non-GMO.

Glycinate is a chelated form of magnesium, bonded to the amino acid glycine, which is why it's marketed for high absorption rather than a cheaper oxide form. The listing bundles several benefit areas, sleep, muscle, bone and heart, under one product rather than positioning it narrowly around a single use.
