Clean Caffeine from Whole-Leaf Green Tea

Natural energy without the jitters or crash

Where Our Caffeine Comes From

Our caffeine comes from organically grown whole-leaf green tea, harvested at peak freshness to preserve natural antioxidants and nutrients.

Why It's Cleaner Than Coffee

Lower caffeine per serving, no acidity, naturally paired with L-theanine, and absolutely no synthetic additives or artificial ingredients.

No Jitters. No Crash.

L-theanine slows caffeine absorption for smooth, sustained energy. It promotes calm focus and mental clarity while preventing energy crashes.
