Glycine Interactions

When magnesium is bound (chelated) to two glycine molecules as magnesium bisglycinate, the amino-acid carrier protects the mineral from binding with phytates and oxalates in the gut and shuttles it across the intestinal wall more efficiently, producing higher bioavailability and less GI upset than inorganic salts like magnesium oxide. Glycine itself is also an inhibitory neurotransmitter that may lower core body temperature and shorten sleep latency, so the pairing supports relaxation as well as absorption.
