BCAAs are chained of three essential amino acids, including leucine, iso-leucine, and valine. These three amino acids that make up protein account for 35% of the essential amino acids in muscle. Since your body cannot synthesize BCAAs, foods and supplements are the only ways for the body to obtain this kind of nutrition.
Many scientific studies and practical experience have shown BCAAs can help reduce muscle inflammation after exercise. BCAAs can help repair the tears when you have to suffer some terrible muscle tears caused by training. Working out at high intensity can cause a lot of muscle damage, causing muscle aches. But don't worry because BCAA can improve the situation. Besides, BCAAs are proved to reduce the ability of muscles destroyed during and after workouts. For example, people who take BCAA before squat exercises have less fatigue.
The muscle will digest BCAA directly while other amino acids come to the liver. This is the reason why you should take BCAAs during exercise. They prevent you from the risk of damage, reduce fatigue, and increase your exercise performance. To be specific, a study in 2006 revealed that BCAAs enhanced muscle recovery after every session.
