The science.

Five mechanisms behind the formula, each tied to published research on the ingredient itself.

How each one works.

  1. Potassium first

    3.3 : 1 potassium to sodium

    Inside your cells, potassium far outnumbers sodium. In the fluid around them, it's the other way round. Most electrolyte drinks pile on sodium and add very little potassium, which pushes things further toward salt. MNRL flips that: 3.3 parts potassium for every part sodium, based on research into the benefits of getting more potassium.

  2. Magnesium, with active B6

    100 mg magnesium + 5 mg B6

    Vitamin B6 comes in a few forms. We use P5P, the one your body can use straight away without converting it first. It's paired with magnesium because B6 helps your body put magnesium to use, and the two have been studied together.

  3. Taurine

    1,500 mg taurine

    Taurine is an amino acid your body already makes. One of its jobs is helping your cells keep the right amount of water inside them, which matters most when you're losing fluid. Most hydration drinks leave it out entirely.

    Lambert IH, et al. Acta Physiol 2015;213(1):191-212

  4. Boron, a supporting nutrient

    3 mg boron

    In a controlled study, about 3 mg of boron a day was linked to people losing less magnesium and calcium in their urine. That study was small and specific (postmenopausal women on a low-boron diet), so we treat boron as a supporting ingredient that helps you hold on to minerals, not a headline benefit.

    Nielsen FH, et al. FASEB J 1987;1(5):394-397

  5. Why there's glucose in it

    3 g glucose

    Your gut absorbs sodium and glucose together, through the same doorway, and water follows them in. It's the same principle behind the oral rehydration solutions used in hospitals. That's why there are 3 g of glucose in each stick: enough to open that doorway, not there as a sweetener.
