synergistic. Glycine lowers core body temperature via NMDA receptors in the SCN while magnesium blocks excitatory NMDA receptors and supports GABA; optimal sleep combination
synergistic. Glycine and cysteine from NAC are 2 of 3 glutathione amino acids; GlyNAC supplementation reverses oxidative stress and multiple aging hallmarks in clinical trials
synergistic. Glycine is the most abundant amino acid in collagen (~33%); supplemental glycine provides additional substrate beyond dietary intake for collagen synthesis
