Whey protein powder is easily absorbed by the human body, so after the fitness training, when the muscle cells are just beginning to repair, drink it at last, usually about two hours after the fitness training. Because when your training is effective, the muscle cells have been destroyed. When your training is over, your body begins to slowly cool down to normal body temperature, and those muscle cells that have achieved results due to fitness training begin to recover. It is best to drink whey protein powder at this time.

Whey protein is mainly used to supplement protein, so general training does not need to supplement protein. Only people who are doing muscle training need to supplement protein, so you need to know whether you need to drink protein powder. Protein powder is not a beneficial and harmless thing. Drink enough water after drinking protein powder, otherwise it will harm your body, especially your kidneys. Because protein powder needs a lot of water to participate in the reaction in the process of supplementing protein to muscles. Otherwise, your body can't absorb these protein powders, so it will do harm to your kidneys.

According to this logic, it is best to carry out muscle building training during the day, preferably in the morning and noon. After your training, you can drink enough water after drinking the protein powder, so that the protein powder can be better absorbed by your body without hurting your body. If you exercise at night and drink protein powder after exercise, you can't replenish enough water, because you are asleep and you can't drink too much water when you sleep, otherwise it will affect the quality of sleep.
