About BCAA Supplements

BCAA Supplements contains the three branched amino acids, which are leucine, isoleucine and valine. This is three of the nine essential amino acids. They are called essential because it is crucial that we obtain them from our diet, as they can not be synthesized by the body and play vital roles in human health. If we don’t consume enough essential amino acids, our muscle and tissue stores are eventually depleted, resulting in low lean body mass and poor health. This typically takes many months and depends on the amount of muscle mass we have to begin with. The largest storage area for essential amino acids, including the BCAAs, is muscle tissue.  


BCAA supplementation is often used during exercise, as an intra-workout. Muscle protein synthesis (or muscle building) is decreased during strenuous exercise, while protein breakdown actually increases, resulting in a catabolic state. Part of the reason for this is an increase in stress hormones, such as cortisol. Based on this, it might seem counterintuitive that resistance exercise can result in larger and stronger muscles. However, once re-feeding with quality protein (or essential amino acids) occurs after exercise, an anabolic or muscle-building environment is created.


It is the leucine in BCAAs that increase the rate of protein synthesis, via mammalian target of rapamycin (mTOR). This amino acid create a more anabolic environment, thus reducing skeletal muscle protein breakdown, as long as there are sufficient other essential amino acids to support muscle tissue anabolism.


BCAAs are naturally found in whey protein, and constitute approximately 15-20% of the amino acids. This is one of the reasons why whey protein is so useful for supporting muscle mass and preventing losses. The leucine in BCAA supplements can also stimulate fatty acid oxidation (fat-burning) and glucose uptake by the cell.


This means that leucine may also improve stamina and improve the rate at which fat stores are used for energy. BCAA supplements help to reduce delayed onset muscle soreness, perhaps due to their ability to stimulate muscle healing. The Journal of Exercise Nutrition and Biochemistry reported in 2013 that BCAA supplementation could reduce creatine kinase and lactate dehydrogenase, which are both markers of muscle tissue damage and general metabolic disruption.


BCAA supplements are best taken immediately before exercise, or towards the first half of your session. Alternatively, they can be sipped on throughout the day, preferably between meals, or with a low protein meal.
