Glycine
amino_acidAlso known as: Aminoacetic acid
About
Glycine is a non-essential amino acid that serves as an inhibitory neurotransmitter in the central nervous system. Research suggests supplemental glycine may support sleep quality by lowering core body temperature through its action on NMDA receptors in the brain's circadian control center.
How It Works
Acts on NMDA receptors in SCN to lower core body temperature; also an inhibitory neurotransmitter in brainstem.
