product info

This answer depends on a lot of factors such as, what's your caffeine tolerance? How much do you weigh? How fast does your body normally metabolize things? To give a general answer, Cumulus takes approximately 40 minutes to kick in.

Great question! Most caffeine pills are encapsulated with gelatin derived (usually) from animal byproducts. Cumulus is encapsulated with vegetable cellulose which has been deemed vegan. The only other ingredients are caffeine, theanine, and vitamins C, D3, B6 & B12. That's it!

This answer also depends on factors like your caffeine tolerance, weight, lifestyle, etc. Generally speaking it should last 4+ hours.

Cumulus is manufactured in the US with ingredients sourced locally and globally.

Cumulus is just the capsule and caffeine, theanine, & vitamins C, D3, B6, & B12 - which means there aren't any fillers or other ingredients that contribute to carbs or calories. All that to say - no calories, carbs, fat or sugars.
