I tried lemon, apple, and grape. Everything tastes great! And it makes me focused and energized for my workouts everyday.

Amino Energy better than the rest

I was introduced to Amino energy by some fitness friends years ago and have used it ever since! Great taste with the Blueberry Lemon gives me a boost without making me shaky or feel weird. My son uses the other products and its all he likes, and has tried them all!

Review by Mike on Dec 24, 2022
The Amino Energy from Optimum Nutrition has been fueling me for over a decade. I don't drink coffee so this gives me that burst of energy I need in the morning and then again in the late afternoon. Some days, Amino Energy gives me the energy and focus I need to make it home in LA traffic.

Good product

Review by Kristin Erickson on Nov 30, 2022
I love the watermelon flavor. It gives me the boost for energy I need for a workout, day with the kids or mid night shift to get me through. So good! I just wish you had the individual sticks back in Watermelon

LOVE the grape!

Review by Jackie on Nov 30, 2022
I’ve been using the grape for years and I love it as my midday perk up!
