QUALITY

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.

This is my go-to amino acid supplement for morning workouts. It really gets me through the whole workout without feeling hungry or fatigued. Grape and fruit fusion are the only ones I like though, so I switch back and forth. If you like really sweet jolly rancher flavors, then you might like some of the other flavors like watermelon and orange. I've tried BCAA Energy from Evolution Nutrition and it is comparable in effect, but the flavors are much worse in comparison, as well as the mixing ability in water. Make sure you look at the caffeine content, as this might not be the best for you if you work out mostly in the afternoon and are sensitive to caffeine. This is great for pre, intra, and post workout.

The Naturally Flavored Simply Fruit Punch is by far the worst I have ever tasted. Very little fruit flavor and not sure if I can force anymore down before throwing the container in the trash. All other flavors tried have been good and easy to drink.

Awful. Both have a bitter taste and strong like a bad pre workout. I even double my water and it’s still terrible. I am completely disappointed because the regular ones are so good but the natural is so bad.

I love the taste and how I feel after I drink it. No jitters, just good energy! I drink it every morning with my breakfast and I have a noticeable amount of energy from it.

Skip the natural stuff! It was bitter and has a chemical after taste. Ironic for a 'natural' line. All other flavors were easy to mix and tasted like jolly ranchers.

Love the Concord grape. I tried the Naturally flavored Fruit punch because of the sale and I think I may have received a bad batch. It tastes like no sweetener was ever added. Like drinking unflavored Alka-Seltzer. Absolutely disgusting. Been looking for other reviews but so far haven't seen any.

Hey everyone! I’ve tried different Amino energy products such as: “Amino Lean,” “EVL,”& “BPI.” Of all these I think this product is the best. It gives you a good amount of energy to get through a workout or a long work day, but not overkill to the point where you’re itchy & giddy. I am a huge fan of this product because it works & the taste is great. I do not recommend the café series. I’ve tried mixing it with cold/hot water, cold/hot milk, and even a blend of water & milk, but the taste was unbearable. Aside from the café series, any other flavor is perfect, if not, at least drinkable. There is also another flavor called “blueberry lemonade” sold at Costco, which is so good 10/10. As you guys can see I’ve tried a lot of flavors. Why? Because it tastes so **** good. Honestly, I think some flavor reviews are a bit harsh, but everyone has their own flavor profile.

When I ordered this back in September, I was just getting back into working out again, so I tried this to give me an early morning kick, keep me motivated on days where I drag. I did a lot of reading about amino acids, caffeine etc and this just happen to be my first try with a pre-workout. I don’t require a strong dose of caffeine so this gets the job done without crazy jitters. I have tried other pre-workouts since but I still purchase ON as well. Also several flavors mix quite well with vanilla protein powder to make tasty drinks.

My favorite BCAA's. The energy is not overwhelming but it will keep you up through your entire workout. I've liked all of the flavors I've tried but the juicy Strawberry Burst is ridiculously good. It is literally the exact flavor of a pink starburst. Freezing it into a Popsicle is a nice healthy way to knock out cravings for sweets.
