What is Leucine?



Of the three amino acids that make up BCAAs (leucine, isoleucine, valine), more and more research is showing leucine to be the driving force behind most of its key mass gain benefits.  Leucine has been identified as a critical nutrient for its role as one of the essential amino acids to stimulate increases in muscle protein synthesis.  In this respect, leucine is thought to play even greater roles in stimulating the process of hypertrophy in skeletal muscle. Consequently, high quality protein powders that contain significant amounts of essential amino acids, in particular, leucine are preferred for use as a supplement.  Leucine may also play an important role in helping to maintain glycemic and insulinemic status, in normal ranges.  Currently, a great deal of research is being completed using amino acids with many studies reporting that this nutrient alone may be responsible for optimal adaptations associated with resistance, particularly increases in muscle mass and improvements in body composition.
