HELPFUL IF COMPLETE: For Amino Acid supplements, you want to have them all in right proportions. Some are essential; some are non-essential. However, they will only be as good as the one you have in least amount. Many otc products are less expensive because they keep the more expensive Amino Acids (e.g., l-tryptophan) to a minimum. You need Amino Acids to build protein and muscle. Whey is usually non-allergenic.
