Out of the nine essential amino acids which all have their place, purpose and role in muscle growth, there is none more important within the amino acid family than leucine.

Over the last fifteen years, biochemistry has only first started to wedged its place in the gym scene. Before you know it supplementation suddenly became a lot more complicated.

It’s understandable why people would be hesitant when trying to wrap their head around the complex terminology being thrown around in modern day gym jargon and it’s become common that when you do get around to do some research, you are bombarded by complicated information which leaves you questioning its accuracy.

Let’s break down the basics of the most talked about amino acid and cover it’s purpose for weight trainers using as simple language as possible.

So first, what is Leucine?

As explained briefly before, Leucine is an essential amino acid which is also one of the three branched chain amino acids. It’s used in the synthesis of proteins.

What is the role of Leucine?

Leucine is the lead amino acid responsible for the stimulation of protein synthesis. Protein synthesis is the process of metabolising and delivering protein properties to muscle tissue. This process is responsible for the repair and growth of skeletal muscle tissue.

The simple and unchallenged analogy used for leucine is to think of this essential amino acid as a lightswitch for muscle growth. You can consume as much protein but having the essential amino acids, in this case, leucine to stimulate protein synthesis and muscle growth is of equal importance in trying to achieve results in the gym.

A study conducted by Massey University in Wellington, New Zealand showed that ingesting protein with five grams of leucine achieved near maximal muscle myofibrillar protein fractional synthetic rate (FSR).

When explained like that, it’s understandable why the bodybuilding community has this fascination with leucine and other amino acids.

Can you receive the necessary amount of Leucine from your average whey, casein protein supplement?

That answer isn’t as complicated as you think. Quality whey protein is considered one of the best sources to get the necessary serving of leucine. That’s not just due to it’s naturally high amount but also the method of which the protein and amino acids are ingested, in shake form, which allows for a much quicker release. Does your whey protein contain as much leucine as you need? That simply comes down to the quality of your whey protein. Unfortunately many protein supplements are clogged with unnecessary fillers which provide no nutritional value whatsoever. This is especially crucial for anyone trying to achieve muscle growth.

Natural Protein Powder’s Whey Protein Isolate offers up to 11.6g of Leucine per 100g which will maximise your ability to develop and build muscle. For those of you looking to cut weight for summer whilst keeping lean muscle tone, this ratio is incredibly important. It is not a result you will get from you average protein supplement. Hopefully, this information doesn’t go astray and will help you  in being able to create a more suitable diet for the results you desire.
At Natural Protein Powder, we urge you to make a conscious decision on which protein supplement is right for not only a better performance in the gym, but the everyday performance of your well being as it copes with the pressures of work, daily activities and everyday life.
