Best Electrolyte tabs by Sodium
Electrolyte tabs ranked by sodium per tab, the headline number and the reason most people reach for one.
Tabs span from near zero to over 1,000 mg of sodium per serving, averaging around 310 mg across our catalogue. Your target is not an average: sweat sodium runs from roughly 300 to 1,500 mg per litre between athletes, and some test above 2,000, so hourly loss is your own sweat rate multiplied by your own concentration. Replacing 50 to 100 percent of it is the working target.
Two guardrails worth stating plainly. Chasing ever-higher sodium does not prevent cramps on its own, and drinking large volumes of low-sodium fluid over many hours is the classic route to exercise-associated hyponatremia. More is not safer, matched is safer. A tab is a fixed dose, which is exactly why picking the right one matters more than it does with a scoop.
