BCAA's are the most crucial when it comes to your muscles. They make up around 35 % of your muscle mass. The 3 BCAA's are.... Leucine, Isoleucine, and Valine.
BCAA's are metabolized in the muscle not the liver like other amino acids. They spare muscle tissue from being used for energy during intense exercise.
You should supplement with all of them. However, leucine is the most crucial of the 3. Leucine is key to protein synthesis. Leucine is 10 x more potent in protein synthesis than other aminos.
So that is the reason that some take extra leucine.
