BCAAs are a class of essential amino acids that the body can use for energy and muscle synthesis.

These essential amino acids are responsible for a large portion of blood sugar production during workouts. This is important to note if you work out in a fasted state or if you’re on a calorie restricted diet.

When you have a balanced carbohydrate, highprotein, and amino acid beverage during and postexercise, this can induce an insulin response. The insulin response helps transport aminos into cells to repair muscle damage and build muscle tissue.
