L-Leucine is one of the nine essential amino acid's that cannot by created by the human body and must be taken in as part of a well-rounded diet.


Leucine is found in protein, and like the other BCAA's (Branched-Chain Amino Acids), it is important in energy production during exercise. Recent studies have also shown Leucine to be the most needed of the BCAA's during exercise, while L-Isoleucine and L-Valine are needed slightly less.


As a dietary supplement, Leucine is the only amino acid that has the ability to stimulate muscle protein synthesis as well as slowing the degradation of muscle tissue.


It is estimated that up to 90% of our dietary intake of L-Leucine can be used for energy during athletic performance and muscle exercise.


Nutrition Bulk's L-Leucine helps to reduce caloric intake and increase energy through the production of growth hormones, and helps burn the lower layers of human fat that aren't always removed with regular exercise and weightlifting.


Leucine may also stimulate the release of insulin, which increases protein synthesis within the body.


A diet rich in Leucine -- along with healthy eating and regular exercise -- has the potential to decrease the chance of type II diabetes, heart disease, high cholesterol, heart attack and stroke with it's highly-effective fat burning qualities.
