Overview

What is Leucine and why should I take it?

Leucine plays a vital role in the development of lean muscle mass, repair and recovery post exercise. It is considered as the most important of the three branched chain amino acids (BCAAs) and should be a key addition to any athlete or gym enthusiast's supplement programme.

Leucine should be taken by anyone who takes part in intense exercise. It has a wide range of benefits regardless of your sports or training goals. These include, encouraging lean muscle growth and repair, and increase energy levels. As an essential amino acid, leucine cannot be synthesised by the body and therefore a dietary source is required. It is naturally found in meat, fish and dairy and is present in high amounts in whey and casein protein. Leucine is the most heavily researched of the three BCAAs (leucine, isoleucine and valine) and has some profound scientific studies supporting its ability to increase protein synthesis. It has also been shown to prevent muscle breakdown and increase energy and endurance.

What are the performance benefits of Leucine?

By promoting protein synthesis, leucine helps to encourage growth and repair of lean muscle. In terms of performance it can improve power and strength and reduce recovery times. During exercise leucine can be used directly by the muscle as energy and can improve endurance performance. Furthermore leucine can promote glucose uptake to increase glycogen replenishment making it a great choice for endurance athletes.

Leucine can be taken any time of day. We recommend one serving in the morning, one pre-workout and one post-workout. As Leucine is not fully soluble some powder will settle on top of the water, this is perfectly normal. To improve mixability we recommend mixing Leucine with your protein shake.
