Optimum Nutrition Amino Energy: An In-Depth Review

Amino Energy

Amino Energy by Optimum Nutrition is an amino acid energy drink available in a variety of different flavours. The product itself has zero sugar and contains 100 mg of caffeine per serving. The caffeine content can be a nice way to boost your morning cardio session, something that Brainflow says Dwayne ‘The Rock’ Johnson uses for his.

It also has 5 g of amino acids per serving, however, we’ll get into the full amino acid profile later. The main benefits of this product are that it aids efforts in the gym whilst also giving you boosts in your day-to-day life with its energy-boosting and mental focusing qualities.

One final highlight of the product is that it contains 30% of your daily recommended dose of Vitamin C per serving, with 24 g per two scoops.

Amino Acid Profile

Amino acids, often referred to as the building blocks of proteins, are compounds that play many critical roles in your body. They’re needed for vital processes like the building of proteins and synthesis of hormones and neurotransmitters.

Amino acids are organic compounds composed of nitrogen, carbon, hydrogen and oxygen, along with a variable side chain group. There are nine essential amino acids.

The three branched-chain essential amino acids are widely used to alleviate fatigue, improve athletic performance and stimulate muscle recovery after exercise. In a study in 16 resistance-trained athletes, branched-chain amino acid supplements improved performance and muscle recovery and decreased muscle soreness, compared to a placebo.

Amino Vital says that you should aim to get around 12 g of BCAA’s per day if you are a male, and 9 g per day if you’re female.

Whilst we can go in-dept with every amino acid, we’re going to give you an overview of the amino acids that are most important to an exercise regime: L-Glutamine, L-Arginine and Beta-Alanine. 

According to Healthline, L-Glutamine is an important amino acid to your body. It helps replenish your body’s glycogen stores as well as helping to reduce fatigue and muscle soreness. L-Glutamine is also a critical part of the immune system, as well as playing a special role in intestinal health. The amino acid is naturally produced in the body but for optimal health you may need to supplement it. 

Eurekalert states that L-Arginine is a brilliant amino acid for exercise. Firstly, it is a precursor to nitric oxide. Nitric oxide is known for helping improve your blood flow through vessels easier, which helps aid the delivery of nutrients to working muscles. Not only this, but it also helps with metabolic waste product removal. Something else than Eurekalert mentions is that L-Arginine has also been shown to increase the levels of growth hormones in your blood. 

A study by the National Library of Medicine has shown evidence that the amino acid beta-alanine positively affects body composition. When supplementing beta-alanine, the study showed that lean muscle increased when supplemented for three weeks. It does this by increasing your ability to improve exercise volume which in turn promotes muscle growth.

Other Ingredients

As well as the amino acid profile listed above, Optimum Nutrition’s Amino Energy also features another 3 key ingredients which make it one of the best amino acid powders around. 

It features 100 mg of caffeine, which is used for energy-boosting purposes. It means that this product can be used to give your body a boost before exercise, or a pick-me-up during your day to day life. 

As well as the caffeine, it also contains 100 mg of green tea extract. Again, according to Healthline, green tea has many benefits. It has been shown to improve your blood flow whilst lowering cholesterol. It has also shown qualities to benefit your heart such as lowering blood pressure. It can also help aid fat burning and fat loss. 

Vitamin C is an important vitamin needed for your day-to-day life. Information extracted from the NHS website says that it serves several, important functions. These include things such as protecting and keeping cells healthy as well as maintaining healthy skin, blood vessels, bones & cartilage. A lack of Vitamin C can also lead to scurvy, however, you would need to be deficient for a long period of time.

Taste

An indicator of whether a product is any good is its taste. Optimum Nutrition Amino Energy has multiple flavours, making flavours that will suit everyone’s taste. The flavours that we sell are Blueberry, Cherry, Cola, Fruit Fusion, Iced Tea, Lemon & Lime, Lime Mint Mojito, Orange, Peach Cranberry, Pineapple, Strawberry & Lime and Watermelon. 

Nick from Barbend said in his review of Amino Energy that he rates the taste of the amino acid powder at 7/10. When commenting on the taste, he mentioned the fruity note of the product but did mention that the Blue Raspberry flavour he tasted was a little sour. When Fighting Report did their own review of the product, they noted how the wide variety of flavours was satisfying, but a con to that is that some can taste a little sweet. However, they do state that many people love the flavours and that they taste the way that they’re supposed too.
