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.

Trash until something changes
Wish this did not have artificial food dyes. I will not be buying again until the ingredients change. I do not care if Grape flavored is purple looking, or if Strawberry flavored is red looking, etc.

  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.
