I am also a sophomore in physical education. I want to drink protein powder, but I don't know when to eat it. I usually start training after four o'clock and eat after lunch or before training.
Take it half an hour after training or before training. Our biochemistry teacher said that supplementing nutrition is like adding water to a pool. First, you fill the pool with a lot of water, and then you can add a small amount of protein every day, because at that time, the body has absorbed a lot of nutrients, no matter how much you eat, people can't absorb it, which is easy to waste resources. Add more protein powder when you start eating it.
