Customer Reviews

Here are some of the postivie feedback this product has received from Amazon verified customers:

“But Amino Energy replaced my morning coffee routine about 3 years ago and I’ve never looked back. It’s an excellent morning pick-me-up for both workdays and weekends. And because it’s a powder, you can easily fine-tune how much caffeine you’re looking for on any given day. I’d never recommend taking as much as the label recommends though, anything more than 2~2.5 scoops gives me caffeine jitters. Start slow and figure out your ideal serving size through trial and error.

It’s also an excellent pre-workout before the gym. Definitely helps pumping iron, and I clearly feel better lifting weights on the days when I remembered to bring some versus the days I’ve forgotten my energy boost. The lemon-lime is delicious (like a non-fizzy 7-Up) and doesn’t leave any unpleasant after-tastes to worry about.” – Peter Sawka

“I’m an avid runner and this product has been a serious game changer for my routine. It hasn’t just helped me with my workouts, it’s also so beneficial for helping me start my day. I run a congressional campaign and as you can imagine, I drink a lot of coffee throughout the day to keep me going. But this mix has helped me reduce my coffee intake because it doesn’t just keep me going, it truly does help me work with more focus and mental energy. I also enjoy the flavor. Initially, two scoops was all I needed to kickstart my day on a strong note but if I want a really want a hardcore workout, I’ll have 4 scoops. For reference, I’m a 30 year old female, 5’5 and 135lbs.” – Zodak

“DONT BUY ANYTHING ELSE!! this is the real deal!! I have tried several others, more expensive and NONE OF THEM compare to this one!! The price is great, the taste is great and the ENERGY!!!!!!! omg the ENERGY you get from this drink is REAL! It says you can use 4 – 8 scoops, I couldnt imagine me with EIGHT scoops! I use 4-5 scoops in a bottle right before my workout and then it is ON!!!” – Kimberly

“This is the second container I have purchased. I have tried the fruit punch and the watermelon. In my opinion, I like the fruit punch better, however both are good flavors. I like to use less water so it is more sour. I usually have 2-3 scoops before I workout. RARELY, I do feel a slight tingly sensation which I’ve heard happens with heavy duty pre workouts. However, this really occurs very rarely. Sometimes if I feel the need for some energy, this does the trick instead of reaching for another cup of coffee!” – Laci Ryan

“This product was recommended to me by a co worker and now all of us are hooked. Although I LOVE coffee, it’s been nice to have found something to replace the expense. Doesn’t give you the jitters. You can drink however much you want-2,3,4, or 6 scoops it doesn’t matter! I like that I could drink just enough for a pick me up in the afternoon but it won’t keep me up late. (Im sensitive to caffeine) I also use this as a preworkout supplement because everything else Ive tried is too strong. Oh and of course the BCAA’s are an added bonus for muscle recovery. Love the fruit fusion flavor. Been drinking it for a while and I’m still not sick of it.” – Anna

On the flipside, here are some of the negative reviews Optimum Nutrition Essential Amino Energy has received.

“This product is very acidic on the stomach and way too sweet. It tastes like a Jolly Rancher. Over time the acidity worsened. I attempted getting ingredient details from the company and they refused. I am now trying Legion Pulse and it is much cleaner and easier on the acid. All ingredients are also listed out without being hidden in some “proprietary” blend.” – Amazon Customer

“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.” – El Lobo

“Orange doesn’t taste good.” – Christina

“This was not for me … didn’t notice any noticeable change in energy.” – Keyana Womack

“I have been drinking this same drink for going on three years. I ordered two of the larger canisters from amazon and received them both with the powder all over the outside of the conister. I made a drink with it and it had a much different taste almost like cardboard/stale. I’d like to have them both replaced.” – Killian Fischer
