what do bcaa supplements do
Branched Chain Amino Acids (BCAAs) refers to three amino acids: leucine, isoleucine, and valine. For people with low dietary protein intake, BCAA supplementation can promote muscle protein synthesis and increase muscle growth over time. Supplementation can also be used to prevent fatigue in novice athletes.
BCAAs also work in your favor by reducing the rate of protein breakdown. They do this (primarily) by decreasing the activity of the components of the protein breakdown pathway, and also by decreasing the expression of several complexes involved in protein breakdown.
