What are Amino Acid Supplements?

At the forefront of health debates, nutritional supplements have remained a popular choice of many who lack in one or more vitamins and minerals. Found online, in stores and on infomercials, people have purchased amino acid supplements with their health in mind.        

About Amino Acids

Behind protein production, amino acids play an important role in building cells, tissue repair, enzyme production and mental health.

The body requires 20 amino acids for protein creation, or protein synthesis, to occur naturally. The human body provides 12 “non-essential” amino acids naturally, leaving eight “essential” acids required from either diet or from supplementation. With one missing “link,” the synthesis process can slow down or come to a complete halt. Proper synthesis requires the right quantity of all amino acids, presented simultaneously.

Complete Versus Incomplete Proteins

Protein classification falls under two categories, complete and incomplete. Complete protein contains all essential amino acids the body needs. Sources of complete proteins include fish, chicken, eggs, milk and cheese. Conversely, fruits and vegetables contain incomplete proteins, each deficient in one or more essential acid(s).

Amino Acid Supplementation

For those lacking in essential amino acids or for those who want to boost their diet with additional essential acids, such as vegetarians, individuals with food sensitivities and bodybuilders, they now have the option of taking an amino acid supplement to fill in the gap. Supplementation comes in the form of concentrated pills and fortified meal replacement and protein shakes.  

Warning

Most manufacturers maintain that their products contain all eight essential acids, including tryptophan, valine, threonine, methionine, phenylalanine, leucine, lysine and isoleucine. However, the Food and Drug Administration (FDA) does not regulate such supplements and warns individuals of the potential dangers of taking such, thus urging a cautious approach.
