Optimum Nutrition Essential Amin.O Energy Key Features

ON Essential Amin.O Energy is a powder that you add to water in order to make an energy drink. According to the product information, it is suitable as a pre-workout supplement or as a way to give you an energy boost in the day. This supplement is going to appeal to bodybuilders but many people are using it for a range of purposes which are not muscle building related, including staying focused at work, doing cardio exercise, or taking part in any other activity where they feel they need a lift.

ON Essential Amin.O Energy contains a blend of micronized amino acids including Taurine, BCAA’s Valine, Leucine and Isoleucine, Beta Alanine (CarnoSyn), and L Citrulline, check out the ingredients tab for the full list.

Amino acids are the building blocks of protein and help numerous functions in the body, including building muscle and recovery. In addition, many of the components here increase nitric oxide levels in the blood that helps stamina and endurance by widening blood vessels. This part of the formula adds up to 5g. All the amino acids are micronized and this is a process that reduces the size of particles, so seems to lead to faster absorption in the body.

There is also a blend of stimulants in the Energy Blend. According to the label, this adds up to 160mg of which 100mg is caffeine. Ingredients include caffeine and green tea extract which can be an effective pairing for fat loss. Although the weight loss benefits of these ingredients are not really explained in the advertising, this combination may help increase metabolism and will suit most of us who have a few pounds to lose.

Does Optimum Nutrition Essential Amin.O Energy Work?

Yes, we think that Optimum Nutrition Essential Amin.O Energy will probably provide you with an energy boost that may feel similar to an energy drink. In addition, the amino acids do provide health benefits and may help boost physical energy and endurance as claimed. Many customers are satisfied that it provides a boost in the gym, and that it does not cause side effects. It is subjective but you may find some slight improvement to recovery time as well.

This supplement looks like a safe pre-workout for whatever type of sport you engage in and as the advertising claims, may help perk you up if needed throughout the day. We like that the caffeine is equivalent to a quick cup of coffee, and that it is combined with green tea which a combination is known to help weight loss. We like that you can make the supplement more powerful by simply doubling the serving size.

What Are The Ingredients of Optimum Nutrition Essential Amin.O Energy?

Serving size is equal to 2 scoops (9g). The information here refers to the 2 scoop serving.

Amino Blend (5g):

• Micronized Taurine: Best known as an ingredient of energy drinks, Taurine is present in the body in brain, eyes, blood, and heart, as well as derived from dietary protein, especially red meat and fish. In supplement form, Taurine may help boost some types of exercise performance where endurance is required such as long distance cycling.
• Micronized L Glutamine: Glutamine is a “free amino acid” meaning that it is used by the body where needed. It is produced by the muscles and sent to organs where needed, especially in the case of injury or trauma. In supplement form it may be effective for muscle building.
• Micronized L Arginine: L arginine helps produce nitric oxide, a natural chemical in the body that regulates blood flow by causing the blood vessels to dilate, so more can pass through. Source
• Micronized L Leucine: This is a Branched Chain Amino Acid so named for the molecular shape, and important for health and recovery and assist in muscle repair after exercise. L Leucine plays an important role in muscle protein synthesis.
• Beta Alanine as CarnoSyn: Beta Alanine is a modified version of the amino acid Alanine, which in turn is an amino acid (protein building block) of carnosine. Carnosine is concentrated in the muscles, although it is also found in other parts of the body including heart and brain. There is strong evidence that improving carnosine levels via supplement use can help improve athletic performance and endurance. CarnoSyn is a leading, some might say THE leading Beta Alanine powder on the market. Source
• Micronized Citrulline: Citrulline is an amino acid that is turned into L Arginine in the kidneys after ingesting. It helps the body improve blood flow and can improve athletic performance and endurance although for this purpose, serving size is usually around 7000mg.
• Micronized L Isoleucine: Branched Chain Amino Acid that induces glucose uptake into cells.
• Micronized L Valine: Probably the least important of the three BCAAs and never tested on its own. However, the 3 x BCAAs are important for body composition and energy.
• Micronized L Tyrosine: Amino acid which is made in the body as well as obtainable from diet. It helps the body convert fat into energy and is also important for mental functioning. It can boost alertness.
• Micronized L Histidine: Involved in numerous metabolic functions in the body and sometimes taken as a supplement in its own right to treat rheumatoid arthritis.
• Micronized L Lysine HCI: part of the general make up of whey protein isolate
• Micronized L Phenylalanine: Amino acid which seems to strengthen the chemical messengers in the body, although scientists have not discovered exactly how it works.
• Micronized L Threonine: Present in cottage cheese, poultry, fish, meat, and lentils, Threonine are used by the body to support connective tissue, the immune system and bone health. Source
• Micronized L Methionine: Can help protect the liver if taken in large amounts.

Energy Blend (160mg):

• Caffeine: Ideal for giving you a quick energy boost, caffeine can increase the speed of the metabolism so help weight loss too but the effects are often short-lived as you become accustomed to use. When used in combination with green tea it may enhance the fat burning effect. A cup of instant coffee contains around 100mg of caffeine.
• Green Tea Extract: Standardised for Epigallocatechin (EGCG): Clinical research has found that green tea has proven health benefits and the antioxidants (ECGC epigallocatechin-3-gallate and polyphenols) found to have anti-obesity and fat burning properties. When green tea and caffeine is taken together, as here they have, the potential to produce significant effects on metabolic targets such as thermogenesis, and fat oxidation.
• Green Coffee Bean: Research results indicate that slight weight loss may be caused by chlorogenic acid present in unroasted or green coffee beans but there is very little real evidence. Limited clinical testing used around 300mg a serving and even then there was very little effect.
• Other Ingredients: Flavourings and emulsifiers such as carrageen, xanthan gum, and Sucralose

Are There Any Customer Reviews For Optimum Nutrition Essential Amin.O Energy?

There are thousands of customer reviews posted on Amazon USA alone and overriding opinion is positive. The main bone of contention is around the taste, with some people enjoying certain flavours while others branding it undrinkable, and so on.

There are too many to mention and it is impossible to pick out a flavour that everyone loves.

Here is a selection of comments about the flavours,

It tastes like fresh pineapple! It’s a great alternative to coffee on hot days. I’ve tried the watermelon and apple flavors as well and they taste just like jolly ranchers. So good!

I absolutely love this product especially the grape flavor!

This customer bought Fruit Fusion and regretted it,

This flavor is awful and it gave me a bad stomach ache, now I love this product and it works really well for me on other flavors, Example: Pineapple and lemon lime. But there was something wrong with this flavor and I returned it and purchased a different flavor, now I am back to liking this product.

The very next comment told a different story,

My first jar was Fruit Fusion which was good and did as expected. I wanted to try another flavor so I ordered Grape.

Huge Mistake

Many people are using as a pre workout supplement,

I really like this product and always use it as a pre-workout. I do increase my amount of scoops depending on how much energy I actually need but I stay between 2-3 scoops and I always feel great. Definitely would recommend!

I love this stuff so much. It’s a quality product that is very versatile and can be used in a variety of ways. I’ve used it as a pre workout, post workout, morning coffee substitute, or for anytime you just need a quick energy boost. Plus, the amino acids help keep muscle atrophy from happening when you’re unable to work out for a while. I’ve been using this stuff for several years now and will continue to do so.
