10 electrolytes reviewed

Electrolyte products, compared on the numbers

Electrolyte products are built to replace sodium, not carbohydrate — most carry next to none — so the price that matters here is cost per 1000 mg of sodium, not per gram of anything. That number varies more than the marketing suggests: some tablets carry triple the sodium of others at a similar price, and box size changes the per-dose math more than flavor does. Potassium, calcium and magnesium are shown too, when a product declares them — the gel and drink mix pages on this site set electrolyte content aside for exactly this category to cover. Sort the table by sodium dose, by cost, or by score to see the field from whichever angle actually matters for your race.
