Glycine is a non-essential amino acid involved in various biological processes, including the synthesis of proteins, collagen, and neurotransmitters. It is also crucial in the production of creatine and supports detoxification in the liver.
In the context of supplementation, glycine is popular for its calming effect on the nervous system and its role in improving sleep quality—both of which contribute to recovery and overall athletic performance. It also plays a key role in collagen production, which benefits joint and connective tissue health.
Because of its multi-functional nature, glycine is sometimes included in sleep aids, collagen supplements, and post-workout recovery blends.
