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.
