What is Instant Leucine?

BULK POWDERS™ have taken it to the next level with Instant Leucine. This an improved form of Leucine, as it has gone through a patented micro-encapsulation process which allows for a rapid dispersion and solubility in water. This means, that unlike many other sources of Leucine, it has an almost neutral taste without any foaming or insolubility when mixed. This unique micro-encapsulation process now offers a more satisfying and convenient way of adding Leucine into your diet. It can be mixed simply with water on its own or with your other supplements.

Leucine is one of the most important essential amino acids required through our dietary intake. Leucine is also one of the three Branched Chain Amino Acids. The increasing popularity of Leucine can be put down to the abundance of strong, credible research demonstrating its effectiveness.

Research has shown that Leucine plays a vital role in the stimulation of the mTOR (mammalian target of rapamycin) pathway. Leucine also contributes to the growth and maintenance in muscle mass, as it is high in protein. 

Leucine can be found in most high-protein foods, particularly red meats such as beef and pork. Supplements such as Whey and Egg Protein are also good sources of Leucine. Instant Leucine now offers an easier way to get Leucine in supplemented form. Due to the improved taste and improved mixing qualities, you can simply consume Instant Leucine on its own or even added to your existing supplements.

Leucine is one of the 3 components of BCAA. Research does suggest that they are best supplemented together to enhance benefits, in which case, take a look at Instant BCAA. Leucine can be added to Instant BCAA to increase Leucine content, or combined with other amino acids such as Glutamine. Post-workout, Leucine should ideally be used in conjunction with carbohydrates such as Waxy Maize Starch or Vitargo and a high quality protein source, such as Pure Whey Protein™.
