L-Leucine Powder is a very anabolic essential amino acid supplement that helps to stimulate protein synthesis. This allows the body to synthesize protein at a higher rate which in turn will help you to increase muscle mass. Aside from increasing muscle size, another main benefit is that it helps to increase natural energy levels in the body. Read the full product description for more information.

What is L-Leucine?

L-Leucine is an essential amino acid, which means that, due to the fact that it is essential, the body needs it, but cannot synthesize it by itself, meaning it has to come from a dietary source, which in this instance, is a supplement. Studies have found that Leucine helps to trigger protein synthesis, making it essential for the growth and repair of muscle tissues. Leucine however, also helps the muscles to generate more energy, which means that they work harder than usual, and you will therefore be able to get more muscle built and have a more productive workout in the gym. Leucine is actually one of three Branch Chain Amino Acids, or BCAAs, for short, and is vital for protein synthesis, making it a very beneficial post-workout supplement.

How does it work?

Leucine works by activating a primary muscle building anabolic pathway known as mTOR, which functions almost like a sensor for amino acids, within muscle cells. mTOR is very sensitive to leucine, and as a result, if leucine levels are low, this forces the mTOR to signal to the cells and tell them that not enough leucine is present to allow the body to synthesize new proteins. Put simply, low leucine levels result in less protein synthesis taking place, so less muscle can be built.

What are the main benefits of Leucine?

Some of the main benefits associated with Leucine supplementation, include the following:

Increased muscle mass

As mentioned previously, Leucine helps to stimulate protein synthesis, making it an extremely anabolic supplement. The higher the rate of protein synthesis, the more muscle proteins the body will be able to synthesize, meaning the more muscle you will be able to build.

Increased energy production

As well as helping to stimulate protein synthesis, Leucine has also been found to help increase natural energy levels within a person, making it ideal for individuals looking to stay active and get the most out of their workouts. The more energy they have, they more productive their workouts will become, making it a win-win.

Fat loss

On top of the aforementioned benefits, experts have also found that Leucine can help to boost a person’s metabolism and can therefore help them to burn off more calories and lose weight. This increase in energy means that not only are you burning more calories and converting them into energy, but the extra energy is also allowing you to push yourself harder than usual, meaning that you will burn even more calories.

Other benefits include:

  • Increased muscle mass
  • Increased strength and power
  • Increased energy levels and endurance
  • Increased rates of weight loss
  • Improved post-workout recovery
  • Reduced LDL cholesterol levels
  • Reduced blood pressure levels
  • Improved immune system function
  • And more...

How and when should it be consumed?

Health Canada Recommended Dose (powder): Adults: 1 Scoop(s) 1 time(s) per day. Mix product well in 1-2 cups of liquid (water, juice, etc.) immediately before consumption. Store in a cool, dry place.

Leucine VS BCAAs

Leucine is one of three BCAAs, the other two being: Valine, and Isoleucine, and so for that reason, you may simply wonder why people don’t just consume BCAA supplements instead of leucine by itself. Well, the main reason for this is that the concentrations of leucine in BCAA supplements, are obviously dulled down because of the other two amino acids, so the effects of leucine will be less pronounced.

What can you stack it with?

As leucine provides such amazing anabolic benefits in terms of muscle growth and repair, naturally, a great deal of bodybuilders often include leucine as part of their muscle-building supplement stacks. It stacks extremely well with supplements including: Creatine Monohydrate, whey protein, L-Glutamine, and Dextrose. Some people will also include it with BCAAs, providing they sip on their BCAAs during their workouts. Combining BCAAs and leucine together at the same time, will basically be a waste of leucine.

My Thoughts on L-Leucine

2-Amino-4-methylpentanoic acid (also known as leucine) is a branched chain amino acid. The molecule has two chiral centers, and the L form is that which can be utilized by humans in protein synthesis. It is an essential amino acid; humans require dietary leucine for continued health.

I am a doctor - but not that kind of doctor. I make no comment on whether or not you should buy this.
