Glycine

Glycine is an amino acid that contributes to muscle and bone structure; heart, brain, and nerve function; and good quality sleep.

While your body does naturally produce glycine, it is also available through protein-rich foods, particularly meat. Glycine can also be found as a dietary supplement in capsule form or as a powder that can be added to various dishes. 

You can also find glycine in collagen supplements, where it is the primary amino acid. This method actually may help your body absorb the glycine. When glycine is bound to other amino acids, such as in collagen, it has to compete for absorption less.

Magnesium glycinate is the mineral magnesium combined with the amino acid glycine. It is needed to produce energy within the human body, as well as form our DNA and bones.
