Glycine

Glycine is the simplest amino acid and one of the building blocks of proteins. It is important for various functions in the body, including the synthesis of proteins, antioxidants, and nucleic acids (the building blocks of DNA and RNA). Glycine is involved in brain function, acting as a neurotransmitter that helps regulate nerve impulses. Additionally, it may support muscle growth and recovery, as well as improve sleep quality. Glycine can be found in protein-rich foods like meat, fish, dairy, and legumes, and is often used as a dietary supplement for its potential health benefits.
