What are Amino Acids?

All amino acids are found in the food we eat, in the form of protein. Protein is made up of chains of amino acids strung together, and when eaten they get digested and absorbed into the system as single units called amino acids. Once in the body, these amino acids are used predominantly for building body tissue such as muscle development, though there are other uses for amino acids such as for energy (~5%) and enzymes. Under certain condition there is a greater requirement for protein and amino acids, such as during periods of rapid growth like in teenagers, while undertaking resistance training, and when there is tissue repair such as after an injury or illness.

Is it true certain amino acids stimulate growth hormones in teenagers?

Some research on certain amino acids has shown a benefit to weight gain and muscle growth, though there is very little evidence to prove that any amino acid supplement works in these ways. There are three amino acids that have been claimed to increase the release of growth hormone in children and teenagers; they are arginine, lysine, and orthinine. An injection of arginine is used to stimulate growth hormone release in children with a deficiency, working for only a short period of time. However, there is no evidence that an oral dose of these amino acids has the same effect. Supplements with these amino acids contain very low doses. Teenagers will get the greatest benefit out of increasing their total energy intake, which will in turn increase their protein intake to assist with muscle growth.
