Amino acids are divided into three main types: essential, non-essential, and semi-essential. The essential amino acids are tryptophan, lysine, methionine, phenylalanine, threonine, valine, leusine, and isoleucine. Arginine and histidine are semi-essential.

Non-essential amino acids are tyrosine, glycine, serine, glutamic acid, aspartic acid, tuarine, cysteine, proline, and alanine. Each can help to balance chemicals in the brain known as neurotransmitters and to help in muscle maintenance, tissue repair, and immunity.

Studies show that amino acids can provide the body with a variety of long and short term benefits, including general metabolic advantages and better cell synthesis and operation. Supplements with amino acids is beneficial for individuals who are interested in enjoying a greater sense of personal well-being and especially for individuals who are physically active, such as athletes and bodybuilders.

Amino acids help fight against unwanted fat buildup in the body and help improve overall metabolic function in the body. Amino acids are also known to improve the immune system's operation, resulting in a stronger line of defense against common diseases and illnesses.

Amino acids also stimulate mental development, in addition to muscular development. A healthy supply of amino acids every day is one of the best ways to help with maintaining healthy cognitive function.
