Amino Acid Supplements

Amino acids are the building blocks of protein and are utilized by every cell in the body for a variety of crucial functions. Normally we obtain amino acids from our food sources, particularly those high in protein; the body breaks these proteins down into their constituent parts and our cells use these to build the specific types of protein each of them needs.

Amino acids are critical to our body's proper functioning. Their role includes repairing muscles, organs, nails, hair, skin, ligaments, and glands. A deficiency in even one of them will severely compromise one's health. Deficient people, however, are not the only ones who choose to supplement with amino acids; some people opt to increase their intake simply for therapeutic benefits.

The most common essential amino acids include:

Meats and other animal products (eggs, cheese, milk) are excellent natural sources of amino acids. is a great consumer resource that collects user reviews for amino acid products.

Recommended dosage: Proteins should account for approximately 15 of the daily diet. Athletes generally need more. Before supplementing, check with a health professional to see which specific proteins are necessary.
