Whey protein powder and muscle building powder can be used for primary fitness, and nutritional supplements such as creatine, nitrogen pump, glutamine, branched-chain amino acids, casein and n- nitrogen protein can be selected for intermediate and advanced fitness.

Food supplement is the best and does not affect the body. Protein powder can be used for a short time, but long-term consumption is not recommended. On the one hand, the high price is mainly the extract in food. As the saying goes, medicine is toxic in three ways, and long-term consumption will affect the body. Protein food is the main complementary food, and milk and eggs are the most economical. A catty of milk a day, two or three eggs is enough. You can't eat too many eggs. I wonder if you have seen the news that a young man eats about 10 eggs every day in order to keep fit. He'd better go to the hospital for treatment because he is not healthy after eating it. Everything has a certain amount. Less is useless, more is harmful. Some people say that people who exercise can only eat egg whites, not egg yolks. Don't listen to them. Most of the nutrition of eggs is in the yolk, and the main component of egg white is water. Of course, they only eat egg whites and eat seven or eight eggs a day. This is a waste.

I wish you success in fitness!
