    Increase lean muscle mass

    Uptake glucose into cells

      What is L-Leucine?

      Leucine is one of the threeBranched 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. Leucine is an activator of the protein known as mTOR, which then induces muscle protein synthesis via S6K; the other two BCAAs may also activate mTOR, but are much weaker than leucine in doing so

      What are the benefits?

      By itself L-Leucine can stimulate muscle protein synthesis; the process responsible for muscle growth and recovery. This is why it is often referred to as the “main” amino acid.
      Supplementation with leucine has been shown decrease muscle soreness, lessen recovery time between workouts, and increase lean muscle mass. Howatson et al. (2012) discovered that leucine (combined with isoleucine and valine) administered before muscle damaging resistance exercises reduced indices of muscle damage and accelerated recovery in resistance-trained males.

      Recommended dose:

      2.5-3 grams taken two to three times daily between meals and with a carbohydrate snack

      Any Side Effects?

      There have not been any reported side effects with BCAA supplement intake: excess BCAAs are usually converted to other amino acid forms, used up as energy, or stored up as fat. However, if you have liver or kidney disease, you should not take in high doses of amino acids without asking your doctor. It is crucial that you always speak to a knowledgeable healthcare provider before taking any dietary supplements, including glutamine. This advice is also recommended for anyone suffering from a health condition.


      As an adult dietary supplement, take one serving (2.8g) two to three times daily with water or as an addition to a protein shake. This product may be consumed immediately post-training.

      Very convenient

      Easy way to stimulate protein synthesis and prevent muscle breakdown

      Great Product & Experience

      I’ve been using Muscle Feast L-Lucine for about 1 year now. It has been a great experience doing business on this website, and results have been even greater. Especially for anyone on a Ketogenic / low carb diet. It has enabled me to burn the fat needed without burning the hard earned muscle.

      Good Product for Protein Synthesis.

      Leucine is an mTor activator, and Directly stimulates Protein Synthesis. So I take it several times per day, and have noticed a difference in Muscle Mass while taking it.

      Awesome product again

      No BS, straight forward quality. Thank you!
