Product description

Natural Stacks was created from a desire to produce the best supplements without any fillers or unnecessary ingredients.
We only include the highest quality sourced ingredients in order to provide the best health supplements possible. Our standard
is built on the foundation that you have the right to know exactly what you put in your body, which is why we have an open
source policy.

Natural Stacks - Smart Caffeine.
Smart Caffeine is a better, safer way to get the energy you need without experiencing anxiety, jitters, or an afternoon crash. Our
ingredients are simple: caffeine and L-Theanine. That’s it! L-Theanine is a natural amino acid found in green tea that eliminates the
undesirable effects of caffeine so that you experience longer lasting energy and an increased attention span.

All Natural Coffee Alternative
Everyone enjoys a good cup of coffee every now and then, and we’ve all experienced the crash that undoubtedly comes right when
we actually need energy. Smart Caffeine is an energy supplement that prevents caffeine spikes and crashes, and helps keep you
focused and alert to improve your productivity throughout the day.

Increase Energy and Focus
Caffeine and L-Theanine combined together create long-lasting energy, a greater attention span, and increased ability to retain
information without the unwanted side effects of jitters and crashes.

One bottle contains 60 capsules that can be taken whenever energy or improved focus is needed

Serving size is 1-2 capsules and should not exceed six capsules per day.

Can be taken daily, but 1-2 days of rest per week from the product is recommended.

100% Satisfaction Guarantee
Natural Stacks provides a 100% satisfaction guarantee. If you aren’t completely satisfied with your experience with Smart Caffeine,
you can return the product for a full money back guarantee.
