So which is best? The three-ounce chicken breast wins hands down. So instead of an amino acid supplement, try real food first and save your money! Additionally, dietary supplements are not regulated in the United States, so what is on the label may not be what is in the product.

Creatine is a supplement that works for explosive sports and has been tested and studied in adults.[1] According to Dr. Joe Chorley in Sports Medicine at Texas Children's Hospital there are no long-term studies showing safety of this product for growing adolescents and until those are available this product should be avoided in young people under 18.[2]
