BCAAs can be used by muscle cells as an energy source which may help offset muscle breakdown during endurance exercise and help support recovery and repair after weight training.* As a result BCAAs are a popular and relevant supplement among those who exercise regularly*. Amino acids are the building blocks of protein and therefore the building blocks of lean muscle.* Branched Chain Amino Acids (BCAAs) refer to three specific amino acids - Leucine Isoleucine and Valine - that the body must obtain from either food or BCAA supplementation. These are called essential amino acids as they are not produced by our bodies naturally and are obtained from external sources. Wild Buck BCAA helps drive performance in the intra-workout phase. It has added muscle activators like L-Glutamine that helps in reducing muscle fatigue and boosts energy during workout.
