People who practice well basically drink tonics, but it is not because they drink tonics that they practice well. To put it bluntly, protein powder is a source of protein, and you don't need to eat enough protein in the basic diet. What really uses this is just a convenient way to ingest it. Calculate whether your daily average intake of carbohydrates, lipids and protein is up to standard, and then consider whether you need protein powder. By the way, if you consider buying protein powder, be careful not to mistake it for domestic plant protein powder. This protein powder contains incomplete essential amino acids and is not suitable as a sports supplement. Whey protein is absorbed quickly, and the absorption time of slow-release protein is long. Besides, I haven't eaten any protein isolate, so it's not easy to evaluate. But as far as bodybuilding is concerned, in fact, protein's intake can still be counted as a whole. In the final analysis, protein powder is just protein, so is no matter how it is publicized. Your diet is so bad that it's useless to eat a spoonful or two. Your diet is good enough, and it's not much better to eat one or two spoonfuls more.
