80-hr weeks require a calm and steady energy source, not just caffeine. bool's nootropic blend helps me ride out the tough weeks (yes, even at 2AM...)

Hangovers fear bool. Took one before passing out and woke up feeling dangerous. The only way to survive the weekend...

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

Swapped my afternoon cold brew for bool. The brain fog lifts quickly without the caffeine jitters. Game changer and pure flow state.

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

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.

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.
