How it works
BCAAs are effective for reducing muscle soreness and perceived exertion during exercise. They are less effective than whole protein for muscle growth because they lack the full spectrum of essential amino acids.
Leucine activates the mTOR pathway to signal muscle protein synthesis. BCAAs also compete with tryptophan for transport into the brain, potentially delaying central fatigue during long workouts.
