Glycine has a calming effect on the brain – it helps you wind down and prepare for sleep. Its role as an inhibitory neurotransmitter has been unfolding over many years of ongoing research efforts.

Easily one of the most versatile amino acids, glycine serves as a building block to proteins (collagen, the most abundant protein in our body, is one-third glycine), and is heavily utilized for the production of heme, DNA and RNA synthesis, glutathione formation, and for enriching the body’s capacity for methylation reactions [1] [2].

The Connection Between GABA & Sleep Disturbances

Posted by Dr. Allison Smith on Wednesday, 20 June

Gamma-aminobutyric acid, better known as GABA, is the neurotransmitter known for its affinity for GABA receptors throughout the central nervous system (CNS). It acts to inhibit excitatory processes – whether they be normal or pathological.

It's synthesized from the excitatory neurotransmitter glutamate in a process that requires vitamin B6 as a cofactor. The delicate balance in the brain between GABA and glutamate is orchestrated by shuttle systems from the Krebs Cycle, the presence of NMDA and GABA receptor modulators, enzyme cofactors, and reuptake mediators.
