What is Smart Caffeine?

Smart Caffeine is simply a combination of two natural ingredients (Caffeine Anhydrous and L-theanine) which have been carefully sourced for purity.

What is caffeine anhydrous?

Caffeine is the energizing compound typically found in many popular drinks like coffee, tea, and soft drinks.  Caffeine Anhydrous is the pure powdered form of caffeine extracted from natural sources.  Its absorbed faster by the body compared to caffeinated drinks and has been shown to give a bigger boost of energy. Another benefit of Caffeine Anhydrous is that you can accurately track your dose.  Smart Caffeine contains 100 mg of Caffeine Anhydrous in each capsule.

Is Smart Caffeine vegan or vegetarian?

Yes, Smart Caffeine is vegan.

I’m very sensitive to caffeine. Can I take Smart Caffeine?

Most likely. We're not doctors and you should talk to your doctor about this. Everyone responds differently to caffeine, but research has shown that the L-Theanine in our Smart Caffeine reduces “jitteryness”. The caffeine dose of one capsule is also pretty low (100mg).

Can I open the Smart Caffeine capsules and mix with my BCAA Drink?

Yes you can open the SC capsules and mix the contents into a drink.  However, caffeine powder is very bitter and it may not taste good.

Is there a money-back guarantee?

Yes! All orders purchased through are backed by our 30-day 100% money back guarantee from the date of purchase. If in the unlikely event you are not completely satisfied with Smart Caffeine, you can email our support desk for an RMA form and Natural Stacks Inc will refund your order after bottles are returned (shipping & handling charges are not refundable).
