Amino Acids are the simplest form of protein that exists. They are the literal building blocks of every protein structure in the body. Tissues such as muscle, skin and tendon have a complex blend of amino acids building their core structure. Hormones such as insulin and growth hormone are formed from chains of amino acids.

Many people find they are unable to maintain a sufficient supply of amino acids for their own body’s requirements. It could be that their diet is restricted, such as through vegetarianism or a stressful lifestyle. Possibly their needs are much higher than can be met by an average diet, as can be the case for serious athletes.
