Amino Acids, Basic

Building Blocks of Life Amino acids are the building blocks of proteins, and proteins are essential to life. They make up the structure of every living organism and make many of the chemical reactions that keep us alive possible. Amino acids are essential for the health of our cells, tissues, organs, and bodily systems. They are also necessary for growing and repairing tissue, and for producing hormones and enzymes. Many foods, including meat, eggs, fish, nuts, and dairy, contain amino acids. Supplementing with amino acids can help people maintain optimal health and prevent disease.
