What is in one serving of ON Essential Amino Energy Drink?
A 12 fl.oz serving of Optimum Nutrition Essential Amino Energy Drink has 100mg of caffeine, 10 calories, and 5g of Amino Blend. It has no sugar and fat.

Caffeine
Amino Energy Drink contains 100mg of caffeine per serving.
The caffeine content of ON Essential Amino is on amoderatelevel. It’s only aquarter of the caffeine limitset by the FDA, which is400mga day. For a more accurate comparison,it’s equivalent to just one cup of coffee.
There will be nothing to worry about for healthy adults as long as you keep your intake toonly one or two servingsfor the whole day. I recommend going forone servingmax.
People with caffeine sensitivity, however, should still avoid this to avoidside effectslike:
- Restlessness
- Shakiness
- Insomnia
- Irregular Heartbeat
- High Blood Pressure
You also shouldn’t have energy drinks in general if you’re under 18, pregnant, or have underlying health conditions. If you want to, you can look for brands withno caffeine.
Artificial Sweeteners
Amino Energy Drink used Sucralose as its primary artificial sweetener. The Grape Flavor has an additional content of Ace-K.
Optimum Nutrition Essential Amino Energy Drink is asugar-freedrink. It used the said artificialsweetenersto give a refreshing taste to its content still.This means you won’t have to worry about going through sugar-related risks if you drink one can.
For an overview,Sucraloseis common sugar alcohol present in most sugar-free foods and drinks. Despitebeing 400 to 600 times sweeter than table sugar, it has no calories.
Ace-Kor Acesulfame Potassium, on the other hand, is only present in theGrape flavor; this is also commonly used in energy drinks. Same with Sucralose,it doesn’t have calories and is 200 times sweeter than sugar.
The drink used only one to two sweeteners in most flavors. I don’t think drinking this will give way to any risks considering that the said types are deemed safe by theFDA.
Calories
Optimum Nutrition Essential Amino Energy Drink has ten calories per 12 fl.oz serving.
The recommended calorie intake for healthy adults amounts to2,000per day. This is as per the guidelines of the FDA, but it will still vary depending on your current bodily conditions.
Nevertheless,you won’t have to make severe adjustments in your dieteven if you take ON Essential Amino energy Drink.
Note that you will also getelectrolytes, specificallyPotassium ChlorideandMagnesium Phosphate, along with the said ingredients above. These will aid in the hydrating effects of the drink.
Overall, Amino Energy Drink is moderate in terms of caffeine. It’s also a low-calorie drink. This makes it a good choice for those looking for a quick energy boost without the usual risks.
Does Amino Energy Drink actually work?
Amino Energy Drink actually works. On a scale of 1 to 10, I’ll give its effectiveness a 7.5.

There’s no doubt thatAmino Energy worksin terms of increasing energy levels. Its100mgof caffeine and its amino blend are enough to make this work. The effects, however, may not last as long as you may expect. This is most especially for those with high caffeine tolerance.
Enhancing musclerecoveryis also aguaranteed benefit. Again, this is because of theexcellent amino blendprovided.
I think it lacked in terms of the drink’s hydrating properties.Amino Energy Drink’s electrolyte content is already good, but you can find other brands with more electrolytes, and thus, better and more practical effects.
