Why Leucine Enriched?

We know that the amino acid Leucine is the most affective out of them all for muscle building and athletic recovery.  Leucine supports these processes in a number of ways:

  • It helps to stimulate the release of insulin, which in turn then enhances the uptake of other amino acids as well as suppressing muscle protein breakdown. 

  • The mTor pathway is modulated-this is the cell survival pathway that monitors the availability of nutrients, cellular energy, and oxygen levels, triggering muscle hypertrophy.

In multiple studies, the research has shown that leucine enriched amino acids provide even greater gains in lean muscle mass, reduced post workout muscle sources and faster recovery than just taking a standard formula of EAA’s.

What do the Studies say?

2011 randomized controlled trial

In a 2011 randomized controlled trial, eight adults completed two separate bouts of cycling for 60 minutes for 13 days. 10 g of LEAAs (3.5 g leucine) were consumed during one bout, and 10 g of a standard EAA supplement (1.87 g leucine) during the other. The results showed that LEAAs increased MPS by 33% more than traditional EAAs (though both were effective).

2018 randomized controlled trial

Another randomized controlled trial from 2018on post-stroke patients with sarcopenia (a condition characterized by loss of skeletal muscle mass and function) showed that supplementation with as little as 3 g of LEAAs resulted in increased muscle mass, strength, and physical function.

2019 Journal of Physical Therapy Study

In terms of athletic recovery, the research is also very promising. A 2019 study in the Journal of Physical Therapy Scienceexamined the effects of LEAA supplementation (3.6 g, 3x/day) on post-exercise muscle damage in 10 young, healthy males. The results of the study showed that LEAAs significantly suppressed exercise-induced muscle tissue damage, suggesting that LEAAs can aid in muscle recovery.

April 2022 randomized, double-blind, placebo-controlled,parallel-group design study

In April 2020, a randomized, double-blind, placebo-controlled,parallel-group design study(whew, say that five times fast) was published in which 20 active young men on a controlled diet (1.2 g/kg/d of protein) were given either 4 g of LEAAs (1.6 g leucine) or a placebo three times a day for four days following an acute bout of lower-body resistance exercise. LEAAs were shown to preserve muscle force production and attenuate muscle soreness more than placebo, even when combined with an already high protein diet.

How can Amino Acid Supplementation Help me?

While an essential amino acid formula can help with cognition, sleep, gut health, metabolic function & general wellbeing. A main benefit of EAA's is to increase our exercise performance, provide more cellular energy & promote muscle building, maintenance & repair.


EAA's for Optimal Performance & Recovery.

  • Repair, Build & Recover.

    No matter what sport you are in, or how you like to train - we can all benefit from better muscle recovery & repair. EAA's stimulate Muscle Protien Synthesis. This is the system your body uses to repair, maintain & build lean muscle tissue. The amino acid Leucine is the signal for this to take place.

  • Workout Crushing Energy.

    The Amino Acid Isoleucine promotes glucose uptake in the muscle cells where it is broken down by the body into an efficient fuel source. This cellular energy is the key to  enhancing athletic performance & daily energy.

  • Stalve Fatigue & Improve Cignition.

    Physical and mental fatigue can hold you back. During activity & exercise, energy is quickly depleted from our muscles and brain, resulting in fatigue, weakened performance, slowed reflexes, and poor decision making.

    Improve both focus and concentration. Our EAA formula helps the body produce an optimal balance of neurotransmitters during exercise, which then permeate the blood-brain barrier and deliver rapid effects.

  • Leucine, Valine & Isoleucine.

    Three of the essential amino acids: Leucine, Valine & Isoleucine work quickly to repair muscle, resulting in reduced recovery time & improved performance. 

    These are known as BCAA's, but when taken without the other six essential amino acids in an optimal formula with a similar breakdown to that of lean muscle, they can have detrimental effects.

    Studies prove that Leucine, Valine & Isoleucine are only effective when consumed in an optimal formula of all nine essential amino acids.

Here's why you should supplement with EAA's.

  • Extremely Fast Absorbtion

    Amino acids' are potent because they are rapidly absorbed by the body and then used to trigger and support muscle protein synthesis.

    In clinical trials, essential amino acids generated more than 4x the peak muscle response of either direct injections of testosterone or human growth hormone (HGH).

  • Leucine Enriched.

    Just 2g of Leucine stimulates Muscle Protein Synthesis as much as 20g of Whey Protein. To be effective, Leucine needs to be combined with the other 8 Essential Aminos.

  • Poor EAA Extraction

    Muscles become less sensitive to protein & aminos as you age, which means the older population will most likely need time as much protein & amino acids when compared to younger people.  On top of this, digestive issues & depleted enzymes related with older age can result in even lower extraction of amino acids. 

  • Varying Amino Acid Profiles

    Amino Acid profiles vary depending on the dietary source, supplementation of EAA’s makes Sure you’re getting all of them in the optimal amounts.

  • The more we use, the more we need

    Like water, our bodies can’t store protein and it needs to be replenished or topped up daily. The more you use, the more you need. 

  • Digestion

    Even if your protein consumption is high, only around 50% of amino acids are absorbed due to digestive processes, metabolism and the gut microbiome. 

  • Dietary Protein

    Dietary protein contains high amounts of None essential Amino Acids - the ones our bodies can produce without supplementation or diet. This puts strain on the liver and kidneys, where as EAA supplementation requires less processing.

  • Pre-workout & Fasting

    Nobody wants to eat a chicken breast right before they workout, and a protein shake doesn't always sit well - especially in the early morning. EAA's make for a great tasting pe-workout & don't break an intermittent fast.
