L Leucine overview

L-leucine is one of the three essential amino acids used in BCAA supplements and intra-workout drinks, suggesting just how important it is to anyone wanting to build muscle, retain lean mass and optimise body composition. It makes up almost 10% of the total amount of amino acids in our bodies and is the fourth most concentrated amino acid in the human body.

Like all essential amino acids, leucine can not be created by the body and must be ingested through food sources or through quality l-leucine supplement choices. 

Leucine is currently thought to be the most important amino acid for encouraging better protein synthesis and is best taken between meals when protein is scarce. Experts talk of leucine "pulsing", referring to a regular intake throughout the day to keep levels of this important amino acid topped up to prevent muscle catabolism.

Of all the three branched chain amino acids, only leucine encourages the creation of protein within muscle cells and therefore contributes directly to muscle development and size.

Consuming leucine alongside protein means our bodies can take up more of the protein itself. Using a leucine supplement between meals ensures the body is kept anabolic and decreases the risk of losing muscle tissue whilst dieting or recovery from high intensity training. 

L Leucine benefits

Branched chain amino acid, essential amino acid, muscle development, hypertrophy, lean tissue protection

Leucine is one of the three branched chain amino acids and can not be created by the human body, so must be taken in via food or an l-leucine supplement. It is the only amino acid which directly boosts the creation of protein in muscles, contributing to hypertrophy (muscle size and development). It will help protect lean tissue, particularly whilst dieting, and is useful as a supplement throughout the day to keep the body in an anabolic state.

L Leucine Suggested use

As a dietary supplement. mix 2.5g leucine with water or non acidic juice (grapefruit juice) and drink 1 to 2 times daily or as required. 1 flat 5ml scoop provides an estimated 2.5g serving. Scoop included in package. Consider creating your own BCAA supplement by also purchasing isoleucine and valine and mixing in a 2:1:1, 4:1:1 or 8:1:1 ratio.

Summary: Must have
Stack well with: Any protein powder
Leucine is a must have to properly spike your MPS and boost the effectiveness of any protein powder. 100% recommended, even though it does not mix well and does not taste good, do not try to drink it on it's own.

Summary: hubby's choice
Stack well with: pre/post workout
Use this to help support intestinal health primarily, and then secondary to that to support the uptake of protein. It also helps with lactic acid build up if you are on your push days. I have it both post and pre with the rest of my preworkout stack.

Summary: Reduces recovery time after exercise.
Stack well with: L Leucine
At the age of 65 I was finding that after hard exercise my recovery time had been increasing for some time, so about a month ago decided to add some BP Leucine to my usual protein supplement. It took a few weeks but I'm definitely beginning to notice a decrease in recovery time after a hard run or work-out. I will certainly continue with the leucine as it's not expensive.

Summary: Increase protein synthesis... Cheaply!!
Stack well with: BCAA or whey
Tastes terrible on their own. But ok in flavoured BCAA's... Enables you to tailor your own ratios. I also add a couple grams to whey protein post workout and take a small amount before bed... Cheapest and most effective supp to increase protein synthesis!!
