The research behind ONE.

Every ingredient is in the formula for a reason. Here's the science.

Why water alone isn't enough.

Water is essential. But it's only half the equation.

Your cells are surrounded by fluid that needs to maintain a precise balance of electrolytes — sodium, potassium, and magnesium — to function properly. Without these minerals, water can't cross the cell membrane efficiently. It moves through your system without fully hydrating you.

This is why you can drink eight glasses of water a day and still feel fatigued, foggy, or cramped. The water is there. The minerals aren't.

75% of Americans are chronically dehydrated — not because they aren't drinking enough water, but because they're missing the electrolytes that make hydration work.

Three ingredients. One job.

ONE is built around three clinically studied ingredients. Each one is included at a meaningful dose, for a specific reason. No filler. No padding the label.

Himalayan Mineral Salt

Fluid balance + thermoregulation

500 mg Sodium

Sodium is the primary electrolyte responsible for fluid balance outside your cells. Himalayan salt provides sodium alongside naturally occurring trace minerals stripped out of standard table salt.

Shirreffs & Sawka, Journal of Sports Sciences (2011)

Potassium Chloride

Muscle function + nerve signaling

200 mg Potassium

Potassium works in tandem with sodium to regulate fluid inside and outside your cells. It supports muscle contraction, nerve signaling, and healthy heart rhythm.

Magnesium L-Threonate (Magtein®)

Focus + memory + mental clarity

72 mg Magnesium

Most electrolytes use magnesium oxide or citrate — forms with poor brain absorption. ONE uses Magtein® — the only form clinically demonstrated to cross the blood-brain barrier.

Flavor from fruit. Nothing else.

Most brands use "natural flavors" — a legal catchall that can include carrier oils, solvents, and fillers you'd never knowingly consume. ONE uses only organic dried fruit for flavor. No natural flavor concentrate. No carrier oil. No filler. Just the fruit, dried and ground — the way it was before food manufacturing got complicated.

What we left out.

1. No added sugar.Zero grams of added sugar. Ever.
2. No artificial sweeteners.No sucralose, aspartame, or acesulfame potassium.
3. No artificial colors or dyes.No Red 40, no Blue 1, no synthetic colorants of any kind.
4. No natural flavor concentrates.Flavor comes from real organic dried fruit, fully disclosed.
5. No carrier oils or fillers.No maltodextrin, no silica, no gums, no anti-caking agents.
6. No gluten, no dairy.Gluten-free and dairy-free by formulation.
7. Non-GMO.Sourced from non-GMO suppliers, verified at every step.
8. Vegan.No animal-derived ingredients anywhere in the formula.

Why the magnesium form matters.

Not all magnesium is created equal. The form of magnesium in your electrolyte determines whether it actually reaches your brain — or gets stopped at the door.

Most brands use magnesium oxide (cheapest, lowest absorption) or magnesium malate (better, but no brain access). Neither crosses the blood-brain barrier. That means your body may absorb some magnesium, but your brain gets none of it.

ONE uses Magtein® — Magnesium L-Threonate. Developed at MIT. The only form clinically shown to cross the blood-brain barrier and measurably increase magnesium levels in the brain.
