## Features

- About this item
- LIKE COFFEE BUT WITHOUT THE JITTERS: Start your day with a joy-filled burst of energy. OPTML Boost combines Caffeine and L-Theanine to energize you and put you in a great mood. L-Theanine neutralizes the anxiety-inducing side effects of Caffeine, so you can fully enjoy its benefits.
- BRAIN-STIMULATING CAFFEINE: Aside from raising energy levels, Caffeine stimulates your brain by inhibiting the neurotransmitter adenosine. This leads to an increase in other neurotransmitters, like norepinephrine and dopamine, which improve your overall cognitive performance. Studies have shown that Caffeine improves various aspects of mental functions, such as memory, mood, vigilance, and reaction time.
- RELAXING L-THEANINE: The amino acid L-Theanine is derived from the tea plant Camellias sinensis. L-Theanine promotes feelings of calm and relaxation, which balance Caffeine’s anxiety-inducing side effects. Often used as a nootropic, L-Theanine also amplifies alpha brain waves, activating a state of calm alertness and improving your creativity.
- CLINICALLY EFFECTIVE, NON-PROPRIETARY FORMULA: OPTML Boost utilizes scientifically-backed doses of Caffeine and L-Theanine. Don’t be fooled by blends that hide their cheap, ineffective, underdosed ingredient amounts within a proprietary blend.
- LIFETIME SATISFACTION GUARANTEE: We’re so confident you’ll be blown away by Boost that we’ll give you a full refund at any time if you’re unsatisfied. Simply contact us, and we’ll take care of the rest.

    Crash free alternative to coffee
  

*by A***A on Reviewed in the United States on July 14, 2018*

Have been using this since last month. Rarely need coffee anymore and it's enough to last me till afternoon and I have no crash at all or any stomach upset which I usually have with coffee.

### ⭐⭐⭐⭐⭐ 







  
  
    Very content
  

*by J***Z on Reviewed in the United States on July 15, 2018*

First time buyer and couldn't be happier. I ordered it last night and came the next morning. I tried out one capsule and I feel really positive and energized. I'm glad I took the plunge on this product. I love how much you get for the price. Best price/quality around. They got me as a repeat buyer for sure.

### ⭐⭐⭐⭐⭐ 







  
  
    Great Balanced Pick Me Up
  

*by S***N on Reviewed in the United States on January 30, 2018*

Have had a great experience with enjoyergy. I've used a variety of caffeine products, and this has given me the best pick me up of anything I've used. What I found to be the best about the product has been the fact that I don't have any form of jitters using it, which frankly was very surprising
