What is Essential Amino Energy plus Electrolytes?

Optimum Nutrition Essential Amino Energy + Electrolytes is the evolution of the tried and tested Essential Amino Energy, with one big advantage: HYDRATION. This product contains 4 key electrolytes so easily lost during exercise. This product from Optimum Nutrition Gold Standard delivers 8 of the 9 essential amino acids, which are all the EAAs needed to slow muscle breakdown and enhance muscle recovery. In addition, they have added integral conditionally-essential and non-essential amino acids to assist with exercise performance and recovery.

What Does Essential Amino Energy + Electrolytes Do?

This product is designed to energise your exercise or competitive sessions. The key electrolytes sodium, potassium, chloride and magnesium, when mixed with water, ensure that your energy levels and mood—which affect performance—do not take a nose-dive. Dehydration is on the of the fastest ways to hit the brakes when it comes to exercise performance.


Dehydration can make everything you lift seem heavier and any distance you need to cover that much further away. Keeping hydrated, particularly in hot and humid conditions when sweat is lost from the body, ensures that you can make the most out of the time you commit to exercise.


The essential amino acids are important stimulators of muscle protein synthesis. This process is actually the laying down of new muscle tissue, or the replacement of old and worn muscle proteins. Free form essential amino acids are the most effective way to stimulate this process, and have been researched for decades now throghout the world, shwoing great scientific reproducability of results1.


The BCAA leucine is an important trigger of mTOR, while 8 of the EAAs, excluding tryptophan, are required to generate the follow through effect ensuring that the mTOR trigger leads to muscle repair or growth2.

Optimum Nutrition Gold Standard product contains key conditionally and non-essential amino acids, such as taurine, arginine and glutamine. When essential amino acid demands are high, supplying specific conditionally-essential and non-essential amino acids can support healthy metabolic activity and exercise performance. Arginine is required for the synthesis of nitric oxide, which helps to keep blood circulating to the peripheries, and muscle.


This amino acid may enhance the muscle pump sensation eagerly anticipted by so many bodybuilders during their sessions. Glutamine has been shown to boost glycogen accumulation post-workout, and assist with the generation of peak torque during training3,4. Additionally, it may help to reduce delayed onset muscle soreness.

The caffeine found in this product is naturally occuring within Green Tea Leaf and Green Coffee Bean, which are also fantastic sources of antioxidants. Given that we generate more oxygen-based free-radicals during aerobic exercise, this is not such a bad idea at all!


Furthermore, these two natural ingredients also deliver theanine and chlorogenic acids, respectively, which may assist with mental calm and thermogenesis, again with respect.


Optimum Nutrition Essential Amino Energy + Electrolytes is a superb way to power through your session with new-found energy. Try it pre-workout, intra-workout, during intense work-related activity, or any time of the day for a supreme boost. Make sure to give it a go on iced-water for a refreshing drink like nothing your palate has ever experiened!
