Stacked provides 36 essential nutrients, protein and nootropics for your brain and body to get you focused and productive.

How much caffeine is in Stacked?

Each serving of Stacked contains 100 mg of caffeine, equal to a small (8 oz) cup of drip coffee. Stacked also contains 200mg of L-Theanine, which helps to balance some negative effects of caffeine (like jitters). Many coffee drinkers are happy with a full serving of Stacked, while those who consumer lower amounts of caffeine (like in tea) may benefit from less than a full serving.

If I have blood sugar issues, can I drink Stacked?

While we always recommend you first consult your physician, our product is lower sugar, 3g to be exact,  than many caffeinated drinks.

If I already take supplements, can I drink Stacked, too?
