Sweat Chloride Replacement
Sweat chloride replacement tracks chloride lost with sodium—usually covered by salt and sports drinks unless lab panels guide medical follow-up.
Sweat chloride replacement addresses chloride lost alongside sodium in sweat—relevant for salty sweaters and some medical sweat tests that measure chloride as a proxy for sodium loss. Table salt is sodium chloride; most sports drinks cover chloride when sodium is adequate.
Rare cystic fibrosis screening uses sweat chloride; athletes should not self-diagnose from DIY tests.
Common questions

Do you need separate chloride supplements?
