Glycine is the smallest of amino acid molecules, yet extremely important in liver detoxification pathways, production of glutathione, DNA, and hemoglobin. It is an inhibitory neurotransmitter which has recently been shown to support healthy neurological function. It is an important component necessary for healthy REM and delta sleep patterns. Glycine is especially helpful in improving the taste of Custom Amino Acids and Custom Vitamin/Mineral Formulas. It has a sweet taste and can be used to sweeten drinks or powdered supplements without altering blood glucose levels.
