Best Electrolyte tabs by Magnesium
Electrolyte tabs ranked by magnesium per tab, for athletes who want more than the sodium-and-water minimum.
Sodium does the heavy lifting in sweat replacement; magnesium and potassium are the secondary minerals, and tabs carry less of them than powders do. Across our catalogue tabs average about 48 mg of magnesium per serving against roughly 72 mg for powders, so a tab is the lighter mineral load by design.
That lighter load is a feature when all you need is salt and fluid without extra calories. If you specifically want meaningful magnesium - long events, a history of cramping, heavy losses - this ranking shows which tabs carry the most, and it is worth checking a powder as well before you settle.
