Concord Grape flavor

Looking for the perfect pre-workout boost or anytime pick-me-up? ESSENTIAL AMIN.O. ENERGY by Optimum Nutrition supports muscle recovery before, during, and after exercise with 5g of micronized free-form amino acids—plus 100mg of caffeine to promote energy and focus.

Frequently Asked Questions

What are essential amino acids?

Essential amino acids (EAAs) are amino acids that your body can’t produce enough of on its own, including leucine, isoleucine, valine, histidine, lysine, methionine, phenylalanine, threonine, and tryptophan. EAAs support muscle growth and recovery.

What are micronized free-form amino acids?

Micronized free-form amino acids are single amino acids that are already in a pre-digested form for faster absorption by the body.

Why is nitric oxide important?

Nitric oxide plays a key role in exercise endurance because it’s a vasodilator. A vasodilator is a substance that supports the dilation of blood vessels for increased blood flow.

Directions

Mix two scoops of ESSENTIAL AMINO ENERGY in 10-12 oz of cold water. FOR AN AMINO ACID BOOST: Consume one or more servings first thing in the morning and/or between meals. FOR PRE-WORKOUT ENERGY: Take 1-3 servings 20-30 minutes before training. FOR POST-WORKOUT RECOVERY: Take 1-2 servings immediately after training. TIPS: ESSENTIAL AMINO ENERGY contains 50 mg of caffeine per scoop, so do not consume after 5:00 PM if you have difficulty sleeping. ESSENTIAL AMINO ENERGY also contains beta-Alanine and may cause a temporary tingling sensation on your skin. This is normal. With continued use, the intensity of the sensation will decrease or disappear.

Not sealed properly

Received with seal broken and powder all inside the shipping box. I'm afraid it's not safe to use.
Very disappointed. I have used this brand many times with no problems.

Wonderfully tasting pre-workout!!!!

Absolutely LOVE the grape optimum nutrition amino pre-workout. If it didn't have the caffeine, I would drink it as water! It gives me the boost I need to either work out harder (heavier or longer) or stay up and do chores. And the amino make it even healthier in my opinion. I used to buy the same product in cans, but I prefer the powder more. If you are on the fence of trying it, don't hesitate and BUY IT! You will not regret it.

Energy, recovery and focus

I usually have this drink after a workouts/runs for energy, recovery and focus. For me, this product helps. I also try to ensure I exercise, take daily supplements and have a good diet in my daily routine. Grape Concord tastes great.
