Product Description

L-Leucine is an amino acid with powerful muscle building properties, due mainly to the role it plays with mTOR. Leucine is one of the three branched chain amino acids and sometimes referred to as the 'main' amino acid due to the most popular benefit of BCAAs (muscle building) being mostly due to leucine. Supplementing Leucine on its own is still beneficial and may be cheaper than BCAA mixes. It still tastes bitter however.

Our microencapsulated L-Leucine powder are available with instant, granular and taste masking, sustained release formula, which can provide a better solubility, fluidity, taste and absorption respectively.

Product Feature and Application

Leucine is one of the 3 branched chain amino acids. These amino acids can be used by skeletal muscle to give energy during exercise. Results of studies have not been reliable in showing that taking supplements of these amino acids improves exercise performance, or builds muscle mass, or helps you recover from exercise. Leucine may help healing of skin and bones. It may increase muscle growth and lean body mass. It may increase production of human growth hormone (HGH). It may help control blood sugar.

Owing to a better better solubility, fluidity, taste or absorption, L-Leucine powder have a versatile application. It is widely used in solid beverage, premix powders, milk powders, shakes and bars, sports nutrition, capsule, tableting, etc.
