Useful is useful, but not the most appropriate. As far as I know, its main component is plant protein (although animal protein will also be labeled, but the amount is not large), which is not as good as pure whey protein. The simple understanding is that the utilization rate of the body, especially the muscles, is different. Can meet the needs of ordinary people for protein, but whey protein is the first choice for fitness. There are mainstream products for bodybuilders in the market, and the whey protein content ranges from 50% to over 90%. The higher the content, the more expensive it is.
