About This Product

  • Essential amino acid delivery
  • Supports energy, focus, and muscle recovery
  • Promotes nitric oxide production
  • Caffeine derived from natural sources
  • Watermelon 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.

Great Pre-Workout Drink
Excellent source for essential amino acids as a pre-workout drink. Amount of caffeine can be adjusted, and watermelon is the best flavor.

Taurine definitely affects the heart rate. With this product my heartbeat was as strong as a drum inside my chest. It's not for me

Best flavor.
Watermelon is my favorite flavor. Tastes just like a watermelon jolly rancher.

I drink it before working out or for a pick me up at work.

Totally recommend it.

Great taste, no jittery feeling, and gives a great pump for my workout!

Joy S

If they don’t have the big tubs I’ll take 4 small ones

Wesley C

I don't drink coffee, so this gives me a little pick up before I go about my day.

A shopper

Best Answer:  two scoops has 10 calories and 2g carbs (sugar)

Susan R
Will this make you gain weight?
A shopper

Best Answer:  Absolutely not. If anything it’ll help you lose weight by increasing your energy to be able to workout harder. Plus it decease my appetite when I drink it, so you’ll want to eat less.
