80-hr weeks require a calm and steady energy source, not just caffeine. bool is the difference between staring at a contract and actually understanding it at 2AM.

- Kiyon Hahm, Big Law Associate @ Cravath

I never go out without making sure I have a bool back at home. Absolutely love bool and it helps me feel 100% the next morning.

- Ethan Kovar, Professional Party Animal

Finally, an electrolyte that doesn't taste like ass.

- Zain Yousef, Unemployed (made all his money on crypto)

The 2pm slump is real. I swapped my third cold brew for bool and the brain fog just vanished. No jitters, just pure flow state.

- William Laast, PM @ Zillow

Half Marathons in Singapore humidity are brutal. This is the only electrolyte that keeps me hitting PBs without that heavy, sugary stomach feeling.

It’s not just a science word.
It’s our business model.

Your cells have borders. While water waits in line, bool creates a cellular vacuum. Using a precise hypotonic ratio, our formula pulls water and minerals directly into your bloodstream — skipping digestion entirely.

think: An IV drip for your pocket.
