Optimum Nutrition Amino Energy provides the essential amino acids (EAA’s), including the branched chain amino acids (BCAA’s) requried for muscle protein synthesis and initiating muscle building. In fact, this is not just some erroneous statment being made to help sell products.


EAAs have been studied for decades now, with a particular focus on muscle protein synthesis. Perhaps the foremost leader in this field is Dr Robert Wolfe, who has undertaken research for NASA on how to reduce muscle wasting in astronauts. Interested yet? Dr Wolfe has authored numerous research papers on the effects of essential amino acid blends.


What Does Essential Amino Energy Do?

Optimum Nutrition Amino Energy combines the EAA’s with beta alanine to reduce lactic acid build-up in the muscle thereby increasing muscle endurance for a hard-hitting gym session. Beta alanine is an amino acid that supports the synthesis of carnosine, a dipeptide (composed of two amino acids) that is found in high concentrations in skeletal muscle tissue and exerts an antioxidant effect, as well as buffering acids1,2

With the addition of nitric oxide precursors Optimum Nutrition Amino Energy dilates blood vessels to supply oxygen and nutrients to the working muscles at a more rapid pace whilst potentiating the all-important muscle pump. This formula contains citrulline, a specialised amino acid that elevates blood arginine levels more rapidly than arginine itself. Just to be safe, optimum nutrition have also added arginine to the equation. These amino acid are used as "raw materials" or "building blocks" to support the synthesis of nitric oxide.


Optimum Nutrition Amino Energy prevents catabolism and ensures you have all the nutritional support for quality lean muscle gains. This is achieved by including eight of the nine essential amino acids. Why only eight? Tryptophan is not required for muscle protein synthesis. This amino acid is not incorporated into muscle protein.

Optimum Nutrition Essential Amino Energy incorporates a natural energy blend into the mix from both green tea extracts and green coffee. And naturally sourced caffeine makes all the difference. Instead of just taking your typical caffeine or caffeine anhydrous, naturally sourced caffeine contains natural antioxidants and other synergistic ingredients, like L-theanine. L-theanine increases alpha brain waves, which help to offset some of the side effects of taking caffeine, as caffeine can sometimes lead to jitteriness or anxiety3.


Essential Amino Energy provides a versatile product that can be used any time during the day for a no nonsense pick-me-up or just increase the dosage for a potent pre-workout energy supplement.
