Of course, after your training, blood reflux and muscle congestion are no longer so obvious. At this time, after you supplement protein powder, creatine and glutamine, these supplements are relatively easy to absorb, and your stomach will start to work, and a large amount of blood will be supplied to your stomach to help you digest and absorb.
In this way, the blood supply to the brain will be more or less insufficient, so people will feel sleepy. After a period of time, you will be almost digested, and most of the blood in your muscles will flow back, and you will be fine.
These supplements should help you recover. Muscle synthesis is done when you are resting. Of course, it can't be completely supplemented. Food supplement is still very important.
Of course, everyone's system is different, and the reaction after taking supplements is also different. I will feel sleepy after eating, but I will be fine after a while. Unless you train a lot, the muscles from excitement to rest will definitely make people tired and sleepy.
