Amino acids are organic compounds that serve as the building blocks of proteins. Proteins are essential for nearly every structure and function in the body, including muscles, skin, hair, enzymes, hormones, and immune support. Amino acids help with tissue repair, muscle recovery, energy production, metabolism, digestion, and overall cellular function. Some amino acids are made by the body, while others, called essential amino acids, must come from food or supplementation. Because they support repair, recovery, and performance, amino acids are often used in wellness, fitness, and medical optimization plans to help the body function more efficiently.
