Myth-buster
Sodium-based solutions reduced cramp susceptibility in exercise and cirrhosis — but the same meta-analysis found no effect on cramp frequency.
This is one of the first systematic reviews to look at sodium for cramps, so the finding is intriguing but far from settled — especially since the benefit was limited to susceptibility, not how often cramps actually occur.
A meta-analysis of electrolyte studies found that sodium-based solutions made people less likely to experience muscle cramps during exercise or in cirrhosis, but the effect was moderate and didn't carry over to reducing how many cramps people actually had. The review was designed to explore potential treatments for jaw muscle pain (TMD), so the sodium finding is a side observation, not the main focus — and the overall evidence on sodium for cramps is still thin.
Where this fits in the evidence
This is among the first studies we've indexed on Sodium for Reduced Cramp Susceptibility — treat it as an early signal until more research accumulates.
