The electrolyte database
Every honest way to
hit your electrolytes.
Sodium, potassium, magnesium — every product ranked by cost per 1,000 mg of the actual mineral, dosed to its real label, not the marketing. Pick the cheapest, the tastiest, or whatever's already in your cupboard, and mix and match across the three. The point isn't one right answer; it's that you can see the whole board.
The branded way for contrast
What you're actually comparing against — priced per serving, not per gram, because that's how they sell it. A stick of any of these is a few cents of the minerals above; the rest is flavour, the wrapper, and not having to scoop. Sometimes worth it. Just know the ratio.
Note the last one: Liquid I.V. contains no magnesium at all, despite the "hydration multiplier" name. The 1,000 mg of sodium in an LMNT stick is about 4 cents of the table salt at the top of this page. That gap — a few cents versus $1.50 — is the whole reason this site exists.
Two things the ranking can't show you. First — the elemental trap: "magnesium malate 2,500 mg" on a tub is the compound; the magnesium in it might be 400. Every mg/g below is the elemental mineral read off the panel, which is the only number that doses you right. Second — cheapest isn't always best: magnesium oxide is the cheapest per mg on paper and you absorb almost none of it; potassium chloride is dirt cheap and genuinely bitter. Cost is one axis. Absorption and whether you'll actually drink it are the others.
Prices drift; the mineral math doesn't. The elemental mg/g comes from labels and chemistry and is stable. Prices were checked in mid-2026 and move constantly — every row links out so you can see today's. Nothing here is sold by us; we hold no stock and take no payment. Own something not listed? Scan its label and we'll dose to it, or read how much you actually lose.
