Once your body uses up carbohydrates as a fuel source during exercise, it switches to other nutrients, including amino acids. BCAAs are highly efficient at providing energy for muscle cells, leading to less fatigue and more mental focus during workouts.
BCAAs activate the pathways in your body that build new muscle. Scientific studies have found that having a BCAA drink after resistance training leads to increased muscle growth.
BCAAs protect muscles from damage during exercise. Taking BCAAs with your workout leads to less soreness, getting you to your next workout sooner and in better shape.
