Description

There are times when you want a hefty dose of caffeine for pre-workout performance. But on other occasions, like first thing in the morning or a late afternoon pick-me-up, what you’d get from a cup of coffee is more appropriate. ON’s Essential Amino Energy offers the best of both with a formula that delivers 100mg of caffeine from natural sources per 2-scoop serving. Decrease or increase the energy level as the occasion demands. Each serving provides 5 grams of micronized amino acids.

    • Excellent product for me 10/10
Flavor Name: Concord Grape Size: 9.5 Ounce (Pack of 1)
I love the taste, it gives me the energy I need to train and good muscle recovery.

    • Great taste and Smooth Energy
Flavor Name: Concord Grape Size: 9.5 Ounce (Pack of 1)
Great Taste and Smooth Energy" I love this product! The Concord Grape flavor is refreshing without being overly sweet, and it mixes easily with water. It gives me a nice boost of energy from the green tea and green coffee extract without the jitters or crash I get from some pre-workouts. I also like that it has BCAAs and amino acids to help with muscle recovery, so it works both before and after workouts. Light, clean energy, great taste, and keto-friendly — it’s now a regular part of my routine. ... show more

    • Better than coffee on mini levels and essential
Flavor Name: Concord Grape Size: 1.29 Pound (Pack of 1)
This is absolutely a must have for everybody. I actually supplement my coffee with this. I used to drink coffee every morning, but this is so delicious and it’s so easy on my stomach, even if I’m feeling a little nauseous or I haven’t eaten any food. This never upsets my stomach and gives me tons of energy just like I drink coffee, but it lasts longer and it’s good for my health. It’s not tricking my brain like coffee does. I literally drink this every single day and I’m on my third container. Sometimes I don’t feel like doing anything especially paying bills or doing tedious monotonous work on the computer but as soon as I take this, I’m good to go. Next thing you know the dishes are done. The laundry is done. The floor is clean and my bills are paid. ... show more

    • First Single Serving, Good Little Energy Boost, Good Taste, Good Presentation *UPDATE
Flavor Name: Watermelon Size: 1.29 Pound (Pack of 1)
So, for right now, I'm going to leave a 4-star review, only because I've just received it, and I haven't had a chance to use it for the reason I bought it for, which is to replace sugar-free Monster energy drinks that I would buy everyday before clocking in at work. I'm testing out a single serving of it now, and will update at the end of this upcoming work week. I'll leave a few initial thoughts, for now: 1. I like the presentation of the bottle; clean and precise, informative. 2. The powder, itself, is very fine and dense. I had to give it a little shake to loosen it up a bit. Reaching in to pull the scoop out left a couple finger tips covered in the super fine powder. Not a big deal, just don't spill it on accident. 3. Because of it's density it takes a short bit to get it all dissolved and mixed in, maybe 20 seconds for a couple scoops. The taste is a mild, refreshing flavor. It's not too tart, not too watered down, and easy to swig down. I'm not noticing an overpowering artificial flavor, it's pretty nice, and it doesn't give much of an aftertaste. EDIT: For this particular flavor, there is a very funky aftertaste; almost like morning mouth, or something, lol. 4. I'm getting a bit of an energy pep that isn't making me jittery, or ramping up my heart rate, but I've only taken a single serving of it (100 mg). It's probably good for a small pick-me-up, here and there. EDIT: Energy boost was good. It took my body a while to adjust to using it, after using popular energy drinks. I usually took about 150mg per serving, which is about one can of Monster, and the energy felt a bit cleaner, healthier. It's okay. So far, it's not bad. As I stated, I'll make an update after a week of using more of it before and during work. EDIT: I'm going to stick with the 4-star review, for now, and try out the Blue Raspberry flavor. I certainly saved more money, per day, as compared to what I'd spend on other energy drinks. ... show more

    • It works for me and is inexpensive.
Flavor Name: Orange Size: 9.5 Ounce (Pack of 1)
It tastes good and doesn’t give me energy drink jitters but definitely gives me energy. I have noticed a definite improvement in recovery after starting to use this product. Way better than store bought energy drinks and hell of a lot cheaper.

I love the flavor of the blue raseberry. I use it as a prework on and love it, look forward to it. Do not give me the jitters after. Mixes really well in a shaker bottle. Will countiue to buy more, bought twice already!

    • Mixes well and gives energy - can't say how well the other claims are.
Flavor Name: Blueberry Mojito Size: 9.5 Ounce (Pack of 1)
I don't know how effective supplements like this really are, but it gives me energy and has a good flavor. It doesn't get gritty if you stick with 2 scoops (one serving) per 16~ ounces (a bottle of water is usually 16.9 or so). I wouldn't say it hydrates you more - caffeine is a diuretic. I don't consume anything else, but I always find myself returning to this when I crave energy. ... show more
