Importance of Amino Acids and Polypeptides
According to studies[iii], amino acids play a vital role in helping the body function properly. Since they help build protein chains in the body, amino acids benefits include assisting in the growth of muscles, maintaining muscle and tissue strength, promoting healing and repair, providing energy to the body, and maintaining healthy skin and hair.
Currently, scientists are performing extensive amino acid and polypeptide research to gain a fuller understanding of their effects on the human body. Amino acids in medicine are continually being explored in clinical research and in animal studies for more information on their functions. While not FDA approved, you can buy polypeptides and amino acid proteins for your research studies.
