Glycine is a non-essential amino acid, meaning that our bodies can produce it on their own. However, dietary sources and supplementation can significantly boost its levels, leading to a myriad of health benefits. Found in high-protein foods such as meat, fish, dairy, and legumes, Glycine plays a crucial role in the synthesis of proteins, hormones, and enzymes. It is also a key component of collagen, the most abundant protein in our bodies, which is vital for skin, joint, and bone health.
