The energetic feeling and focus from the Caffeine is harnessed and smoothed over with L-theanine. Caffeine users often complain about jitters, but Smart Caffeine supplies enjoyable energy.

How it works

Caffeine is consumed by millions worldwide. It's an efficient natural stimulant that is well tolerated by many people, and Caffeine can make you feel more energetic and focused. But it's not the type of energy and concentration you want for productivity.

On its own, Caffeine is not a great enhancer of mental performance. Users often experience a jittery mental state followed by a crash. Drinking a sugary coffee or energy drink doesn't provide the type of energy and concentration you need to get things done.

That's why we include L-theanine (L-tay ah neen) in SMART CAFFEINE™. It's a naturally occurring amino acid with benefits that include mental relaxation, alertness and perhaps most importantly, increased alpha brain wave activity. This Natural Stacks product provides a clear and focused energy feeling, rather than the short-lived stimulant rush of Caffeine by itself.

Brain waves are weak electrical impulses emitted by your brain that can be measured on the surface of the head. The predominant frequency of these electrical impulses correlates with different types of mental states.

Brain waves are classified into four categories (Delta, Theta, Alpha, and Beta), each with an associated mental state. Stimulants, like Caffeine, promote Beta waves and suppress the others. It can be very difficult to focus and concentrate when you are emitting Beta waves.

Delta waves are only seen in the deepest stages of sleep and Theta waves are seen in light sleep and drowsiness. Alpha waves are present during wakefulness where there is a relaxed and effortless alertness. Alpha waves create a calm and productive state of mind. Studies have shown that L-theanine, an amino acid stimulates the production of Alpha brain waves.

Suggested use:

take a serving of 1-2 capsules whenever focused energy is desired. Avoid use in the evening. Total daily dosage should not exceed 6 capsules. SMART CAFFEINE™ can be taken daily, however we advise taking 1-2 days off per week (weekends for example). U.S.A manufactured in a GMP facility.
