Optimum Nutrition, or ON as it is usually called is a well known USA brand that is available worldwide.
Optimum Nutrition Essential Amin.O Energy is a powdered supplement that you add to water in order to make an energy drink/pre-workout supplement to drink any time. It contains 5g of amino acids per serving plus caffeine and green tea, and looks like a safe and effective way to boost energy while delivering some health benefits as well. If you are looking for a little kick and are trying to keep fit and lose weight, it looks to tick these boxes. Optimum Nutrition Essential Amin.O Energy is not a hardcore pre-workout supplement but certainly has a general appeal, making it popular with customers.
Optimum Nutrition Essential Amin.O Energy looks safe for most people. If you do have any issues with ingredients such as Beta Alanine or caffeine you should read through the ingredients list before you buy.
According to customers, potential side effects may include stomach aches, headaches, and feelings of muscle weakness.
Common side effects of caffeine include jitteriness, insomnia, and anxiety.
Optimum Nutrition Essential Amin.O Energy is not expensive. Buy from the official site and it costs $19.99 for a tub of 30 servings and $37.99 for a tub containing 65 servings.
If you use as a pre-workout you should be aware that serving size is 4 scoops rather than the default 2 scoops mentioned here.
You choose your flavour at the point of sale. It is also on sale from a wide range of outlets so you may be able to shop around for price.
We like Optimum Nutrition Essential Amin.O Energy as a safe energy drink that may suit some people as a pre-workout supplement, or as something to drink before engaging in sport. We like the wide choice of flavours and the money-back guarantee. The high level of customer feedback is impressive with most people extremely favourable and enjoying this drink for various reasons. Yes, there are some issues with the various flavours but that is the penalty one pays for plenty of choices!
In our opinion, if you double up on the serving size, this will be an effective pre-workout supplement with very few side effects, and all with the added advantage as functioning as an energy drink.
What’s not to like! This is certainly not the strongest pre-workout supplement in the world and nor does it claim to be, but if you are just starting out or are fed up with the stimulant side effects of other pre-workouts, we think that Optimum Nutrition Essential Amin.O Energy could be one to try.
We recommend Optimum Nutrition Essential Amin.O Energy to our readers.
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.
ON Essential Amin.O Energy comes with a wide choice of flavours: Blue Raspberry, Blue Lemonade, Blueberry Mojito, Conchord Grape, Cotton Candy, Fruit Fusion, Grape, Green Apple, iced Cafe Vanilla, Lemon Lime, Mocha Cappuccino, Orange, Peach Lemonade, Pineapple, Strawberry Lime, and Watermelon.
If you are trying to avoid artificial flavourings, ON Essential Amin.O Energy Naturally Flavoured is available in Fruit Punch, Peach tea, and Raspberry Lemonade.
Optimum Nutrition was founded in 1986. There are three manufacturing bases across the USA where the supplements are manufactured to strict standards of quality. ON is part of Global nutrition group Glanbia which is headquartered in Ireland and listed on the Irish and London Stock Exchange. ON supplements are on sale worldwide from thousands of retailers and is a well-known brand.
According to the advertising, Optimum Nutrition Essential Amin.O Energy is a “Unique Combination of Aminos and Caffeine”.
You can take it any time you need it and increase the strength if necessary,
“Mix up ESSENTIAL AMIN.O. ENERGY™ anytime you want a fruit flavored or coffeehouse inspired boost of energy and alertness.”
“You can determine what’s appropriate for any situation, adding a 2-scoop serving to water for an afternoon pick-me-up or increasing the amino acid matrix to 10 grams with a 4-scoop pre-workout energy supplement that delivers 200 mg of caffeine from green coffee and/or green tea extracts.”
The three key features are as follows:
Other important points:
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.
Serving size is equal to 2 scoops (9g). The information here refers to the 2 scoop serving.
There are literally thousands of customer reviews for the various Optimum Nutrition Essential Amin.O Energy flavours and while there are negative reviews, very few customers mention side effects. There were a couple:
However, if you have issues with caffeine or beta Alanine you may notice:
Not suitable for individuals under 18. Avoid if you are pregnant or breast feeding. If you do notice adverse effects cease use and take medical advice if necessary.
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.
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.
