Is Yu Kanglai protein powder effective? Can it really improve immunity?

Your good friend: When you ask whether the protein powder is effective, you can say that it is effective, but compared with what, the protein you mentioned is easily digestible animal protein. If it is not a special case, drinking milk directly is more nutritious than protein powder. The total amount of food we eat is counted. You ate a little protein powder, what did you eat the rest? Generally speaking, milk is better than protein powder!
