Glycine and the Alpha-Gal Friendly Diet

Glycine is a non-essential amino acid that plays a role in protein synthesis and various metabolic processes in the body. It is naturally found in high-protein foods such as meat, fish, dairy, and legumes. In the food industry, glycine is used as a flavor enhancer and can also act as a buffering agent to maintain acidity levels.
