Question 1: Protein powder is mostly a dietary supplement, so its ingredients are not as good as food. General sports nutrition supplement manufacturers have their own recommended methods of use, and the fitness industry also has recognized methods of public use. It's just a spoonful or two after training and a spoonful before going to bed. You can use it accordingly, and at the same time, you can find a more suitable way to use it in retraining, which may not be strictly followed.

Question 2: Protein powder is different. At present, there are many classifications in the market, such as whey protein, soybean protein and egg white protein. And ordinary protein, classified protein, etc. Others are classified according to additives, branched-chain amino acids, glutamine and vitamins. There's nothing magical about it. Generally, what we see is classified according to raw materials. Soybean protein belongs to plant protein, whey protein and egg white protein belong to animal protein. Plant protein, also known as incomplete protein, contains incomplete essential amino acids, while animal protein is relatively comprehensive. Therefore, most body-building nutritional supplements use animal protein. At present, the overwhelming whey protein on the market is good. I suggest you use whey protein.

Question 3: Is this for the sake of fitness? According to your needs, the amino acids needed for muscle synthesis are generally comprehensive, so people who exercise generally use animal protein, but if you are a vegetarian or allergic to milk, many eat vegetable protein. According to their own actual situation, from the general experience, the effect of animal protein is still relatively good.

Supplementary question: Is protein powder normal or not, as I said just now. First of all, I appreciate that you can use sports nutritional supplements, which is a good habit. If I lift it, you can use whey protein.

There are individual differences for reference.
