The calculator gives you your exact number. The kit is designed to make it a thing on your shelf: a blending jar, a calibrated scoop, and your personal recipe card — printed waterproof from your saved formula. Mix a month once. Scoop it daily. Dosed to one body: yours.
A wide-mouth blending jar sized for ~30 sessions of your blend — pink salt, potassium chloride, magnesium — at your ratio, locked in once so no session needs a scale.
See your jar recipe →One level scoop = one session. The card tells you your scoop size; the ratio inside the jar makes it accurate without weighing. The math is the product.
Why ratios beat tabs →Printed from your saved formula: your Na · K · Mg, your jar blend, your per-session scoop, your reorder list. Gym-bag-proof. No two cards are the same.
Preview a card →Your minerals arrive sealed from the brands you already trust — Skratch, Redmond, NOW — via the links on your card, about $1.50–2 a session at bulk. Nothing repackaged, nothing scooped by strangers, nothing with our label where a supplement label should be. That's not a limitation; it's the design: the personalization lives in the math and the vessel, and the ingredients stay exactly as their manufacturers sealed them.
Nothing is for sale on this page. Everything the kit would print is already yours today: run the calculator for your number, then follow the jar recipe to mix a month at your ratio.
Sweat sodium varies tenfold between people. Every pre-mixed tub is someone else's average. Your jar is blended to your concentration — that's the whole point.
The primary sources →Your blend at bulk beats pre-mixed tabs on cost AND completeness — potassium and magnesium included, which most tabs skip.
