Review of amino energy naturally flavored

Review by Casie on Sep 6, 2023
Verified purchase
I have fruit punch flavor. Flavor is pretty good.

Bought this because it was free of dyes and sucralose / other additives and love it! Please bring the juicy strawberry burst line over to this!

Review by Josh on Jul 19, 2023
Bought this because it was free of dyes and sucralose / other additives and love it! Please bring the juicy strawberry burst line over to this! I'd love to see the lemon lime also. I had to switch over to this because sucralose is a negative impact to metabolism and inhibits insulin production which could cause diabetes in the long term.

nice flavor

i loved the flavor and how i got better while lifting

Have an older container of this product and just now trying.

Review by Anita on May 31, 2023
I just tried a product I bought approx a year ago and was going to website to suggest lower sodium. I love the watermelon taste and now see it is naturally flavored and much lower sodium. That is a good move!!!


Review by Josh Bachelder on Apr 24, 2023
I left Optimum Nutrition when I discovered what surcalose, acusulfame potassium, and other artifical sweeteners were and how bad they were for you. Thank you guys SO MUCH for bringing me back to you with your naturally sweetened product line. The peach lemonade tastes like peach rings. I WILL be buying your amino again, finally, from here on out. It’s the best amino complex there is and helps insanely with pre and post workout and the amino acids help your mood like crazy! Highly recommend and so happy for this. Please please please make this in cans and sell at speedway!

Senior morning drink

Review by Nicole Patti on Apr 8, 2023
one scoop a day in 10 oz water helps senior mom maintain mental alertness, energy for daily activity, positive social interactions, and daily regular bowels, also curbs appetite from snacking junk food to choose healthy fresh options for meals win win overall, budget is less than a dollar a day for one scoop a day bc she is under five ft tall weighing under 140

Please bring this back

Review by Nitti on Feb 2, 2022
Please make more products with stevia.

Exactly what I've been searching for!

Review by Ashley on Jan 23, 2022
THANK YOU for finally making a naturally flavored pre-workout sweetened with stevia that taste great and actually works. My boyfriend and I were drinking the other version for a long time but had to stop because we didn't want to consume a product with Sucralose & artificial flavors everyday so we were SO happy to see this clean version at our local sprouts. Please make more flavors!!
