Customers review summary

The Optimum Nutrition Amino Energy watermelon powder stands out for its refreshing, candy-like flavor and easy mixing that makes it simple to prepare without special tools. Many customers appreciate the balanced caffeine level, electrolytes, amino acids, and noticeable boost in energy and recovery for workouts. A minority report minor mixing or packaging issues and occasional jitteriness, yet most say it enhances workouts and daily energy with a pleasant taste.

Great in taste and efficiency!
This review was collected as part of a promotion
The smell and flavor of the amino energy is great! I do hope they make other flavors as watermelon isn't my favorite. Not a large aftertaste which is a huge plus!

Delicious pre workout
This review was collected as part of a promotion
I loved this pre workout. Flavor is delicious, but male sure to put a lot of water. It's easy to mix and gives you a boost of energy. It is also good after a workout.

Great Taste
This is a very tasty beverage. It helps me after a run to rehydrate. The only downside is that it's a little clumpy, but I would purchase it again.

Watermelon wave of energy!
This review was collected as part of a promotion
My husband loves this brand of aminos so when I saw this brand was an option for my campaigns I knew it was the perfect opportunity to try it out myself. This product incorporates energy and hydration making it a great value as it combine what would normally be two products. The watermelon flavor is delicious and mixes well. My husband even tried it and likes this upgraded version from the brand.

Not the worst but not my favorite
This review was collected as part of a promotion
This hydration and energy mix is pretty good. I find it mixes really well without leaving chunks of powder. You can tell it has caffeine because it definitely perked me up after drinking it. Nothing crazy but noticable. Flavor wise I was not a huge fan, if you like that sweet overly fake watermelon flavor this may be for you. Reminded me of a watermelon jolly rancher flavor.

Super tasty, easy to mix and gives me great workou
This review was collected as part of a promotion
What is in this magic drink?! I mean there is definitely a list of things (ingredient list pictured), but none of it specifies that it's basically pre-workout without the weird skin crawling itch. Taste is so good and it mixes in super easy (I just use a straw, no fancy mixer required). I will definitely be purchasing again!!

Good product bad packaging
This review was collected as part of a promotion
This loses a store because of the packaging. That is why this picture is what I have submitted. The container was almost impossible to screw shut. Powder went everywhere.But now to talk about the product itself. I used it several times before my strength workout. I found that it gave me energy and kept me hydrated. I would purchase this again in the future.

Good for hydration
This review was collected as part of a promotion
Optimum nutrition, amino, energy, watermelon, splash hydration powder is great for those super hot days when water doesn't feel like it's doing enough. Having the added green tea, extract and green coffee, bean extract really helps with some added energy.
