Why ONE
Magnesium L-Threonate
Most electrolytes skip the brain. We didn't. Magtein® is the only form of magnesium clinically shown to cross the blood-brain barrier — supporting focus, memory, and mental clarity alongside hydration.
Real Organic Fruit. Nothing Else.
Our flavor comes entirely from organic dried fruit. No carrier oils. No fillers. No natural flavor catchall. Just the fruit — the way it should be.
Mineral Salt Done Right.
We use Himalayan mineral salt — rich in trace minerals, not stripped down sodium. Proper cellular hydration starts with the right salt.
