It is recommended to supplement it every day. Not to grow muscles, but to increase immunity. China is a country lacking in protein. More than 20 years ago, it advocated a bag of milk every day. This makes a group of sickly and cramped post-80s grow up. But it still doesn't change the fact that protein is not enough. Especially after fitness. After strenuous exercise, immunity will decline within 24 hours. It is easy to get sick at this time, and protein and vitamins need to be supplemented. People who don't drink protein powder often go to the gym and love to get sick. Didn't you find this problem? So protein powder is recommended to drink some every day. It is always good to increase immunity.
