BCAA supplements can provide an energy boost during workouts, but they are not a direct source of energy. BCAAs can help prevent fatigue during exercise and improve mental focus, which can help to increase energy levels indirectly. However, BCAAs do not contain calories, so they will not provide a significant energy boost on their own. It's important to note that BCAAs should not be relied upon as a sole source of energy, and a well-balanced diet is crucial for overall energy levels.
