What is L-Leucine?
Pure Nutrition L-Leucine Powder is an essential amino acid supplement suitable for all active individuals, regardless if you’re an athlete, a weekend warrior, a bodybuilder, or casual gym-goer. L-leucine is arguably the most important essential amino acid for stimulating muscle protein synthesis, with scientists referring to it as the “master switch” of muscle building. Our L-Leucine Powder contains pure L-leucine in its free form, allowing for rapid absorption and utilization by muscle tissue.
Benefits of L-Leucine Powder
Branched-chain amino acids (BCAAs) are comprised of three essential amino acids: leucine, isoleucine, and valine. These particular amino acids must be obtained through diet since humans don’t synthesize them endogenously. Research has found that the BCAAs, especially L-leucine, are crucial essential amino acids that regulate muscle protein synthesis (MPS).1 Therefore, supplementing with L-Leucine Powder helps stimulate muscle growth, inhibit muscle tissue breakdown, promote recovery after training, and may even enhance fat loss on calorie-controlled diets.3, 4
While most animal protein and animal-derived protein sources contain some L-leucine, the body has to digest and breakdown the peptide bonds so that it can actually utilize the individual amino acids present in food. Thus, supplementing with free-form L-leucine means the body absorbs this essential amino acid much quicker and doesn’t require the digestive enzymes that are usually necessary for breaking down proteins. This is generally why gym-goers and athletes prefer free-form amino acid supplements before, during, and immediately after training for igniting the muscle recovery process.
This makes L-leucine is a superb option for those who are serious about building lean muscle mass and taking their results to the next level.
Evidence-Based benefits of L-Leucine include:
- Enhance muscle protein synthesis and inhibit muscle protein breakdown
- Promote recovery during and after your workout
- Support fat loss while protecting lean body mass
- Encourage healthy insulin function and glucose metabolism
What Makes Pure Nutrition L-Leucine the Best L-Leucine Supplement?

Suggested Usage
Mix one tablespoon (5 g) of L-leucine in 8 oz of water or juice and consume immediately before and after exercising (i.e. pre- and post-workout). Taking 5 g of L-leucine between meals spaced 5-6 hours apart may also help increase muscle protein synthesis.
