WHAT PEOPLE ARE SAYING
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.

Himalayan Salt
We use Himalayan mineral salt — rich in trace minerals, not stripped-down sodium. Proper cellular hydration starts with the right salt.

Frequently asked questions
What is ONE?
ONE is a single-serve electrolyte stick pack designed for people who care about what they put in their body. Every stick contains a clinical dose of Magnesium L-Threonate (Magtein®), Himalayan mineral salt, and organic dried fruit. No sugar, no "natural flavors," no fillers. Built for daily use.
What makes ONE different?
Three things. First, we use Magnesium L-Threonate (Magtein®) — the only form of magnesium proven to cross the blood-brain barrier. Most electrolytes ignore the brain. Second, our flavoring is 100% organic dried fruit, not "natural flavors." Third, we publish every ingredient and every dose — no proprietary blends, no marketing fog.
What is Magtein® (Magnesium L-Threonate)?
Magtein® is a patented form of magnesium developed at MIT. It's the only magnesium form clinically demonstrated to elevate magnesium levels in the brain, which is why it's been studied for working memory, attention, focus, and sleep quality. Most magnesium forms (oxide, citrate, malate) reach your muscles but not your central nervous system. Magtein® does both.
When should I take ONE?
For most people: first thing in the morning with 12–16 oz of water. For training: 30–60 minutes before, or sip during. For travel, heat, or recovery from a hard night: 1–2 sticks throughout the day. There's no wrong time — it's just clean hydration.
How do I store it?
Keep it cool, dry, and out of direct sunlight. The single-serve sticks are stable for 24+ months unopened. Once opened, mix and drink within an hour for best flavor.
