Many BCAA products emphasize the dosage of leucine, because leucine alone can activate the mTOR pathway of other growth signals, and it also has a great effect on muscle repair and fat burning. But the more leucine is not the better. A study from Baylor University found that men of the right age were supplemented with 2:1:1 BCAA, and the other two groups were given a placebo and leucine to exercise one leg. It was found that BCAA had the most effect in increasing protein synthesis. Well, surpassing the leucine and placebo groups.
Numerous studies have shown that BCAA helps reduce fatigue, which can be attributed to the role played by valine, and the three amino acids of BCAA must be taken in at the same time to be fully absorbed by the body. So it's not that simply supplementing leucine can maximize the effect. Moreover, some studies have shown that isoleucine can promote 35%-70% glucose uptake in muscle tissue.

Someone will say
BCAA comes from food
Why do you have to choose supplements?
Food processing tends to reduce meat
And many other protein rich in protein content
This is why most people
