Sarcosine also known as N-methyglycine, is an intermediate and byproduct in glycine synthesis and degradation.

This product is metabolized to glycine by the enzyme sarcosine dehydrogenase, while glycine-N-methyl transferase generates from glycine. It is a natural amino acid found in muscles and other body tissues.

In the laboratory, it may be synthesized from chloroacetic acid and methylamine. It is found naturally as an intermediate in the metabolism of choline to glycine. This amino acid is sweet to the taste and dissolves in water. It is used in manufacturing biodegradable surfactants and toothpastes as well as in other applications.

It is ubiquitous in biological materials and is present in such foods as egg yolks, turkey, ham, vegetables, legumes, etc.

Formed from dietary intake of choline and from the metabolism of methionine, and is rapidly degraded to glycine, which, in addition to its importance as a constituent of protein, plays a significant role in various physiological processes as a prime metabolic source of components of living cells such as glutathione, creatine, purines and serine.


A daily 2 gram administration of this amino acid based supplement has been shown to boost NMDA receptor activity. This stimulates the natural production of testosterone for hormone elevation . It also makes for the perfect testosterone booster/performance enhancer
