Protein powder can be roughly divided into plant protein and animal protein, among which plant protein includes soybean protein and peanut protein. Animal units include whey protein, beef protein, etc.
If it is only used for health care, Amway Nutrilite, a product containing plant protein, is enough. If it is exercise, of course, whey protein is chosen!
The reason why you are advised not to buy domestic miscellaneous brands is that the production technology and safety standards are not guaranteed! This protein extraction technology is not so mature in China, and the relevant supervision is not enough. Take Kangbite, which makes the loudest whey protein in China, for example, its raw materials from protein are directly imported from abroad! It is because the imported raw materials from protein are of high purity and there are no impurities harmful to human health! After all, foreign food safety standards are still very strict.
