Hi Zygridh, I agree with you that amino acids are essential components that are derived from the breakdown of proteins in the digestive system. The body manufactures the non-essential proteins, so there is no need of ingesting them. Natural sources of amino acids include eggs, dairy products, meat and buckwheat. Indeed, supplemental amino acids are useful, but I believe that they are not as effective as the God-given natural sources of amino acids. I believe that we should try to get most if not all of our amino acids requirements from the diet and desist from using supplements (Berry, 2019). Reference Berry, J. (2019).
