Roll Call does not check drug interactions or assess personal safety.
An essential mineral electrolyte, most familiar as part of table salt, that regulates fluid balance and nerve signaling.
Why it’s used
Rarely taken deliberately as a supplement for a benefit; when it appears on a label it is usually part of an electrolyte blend or a mineral salt form of another ingredient.
What the evidence is for
maintaining fluid balance and nerve/muscle function.
What the evidence says
NIH ODS and major health bodies describe sodium's physiological role as well established, but public health guidance generally focuses on typical intake being higher than needed rather than on any benefit from adding more.
Dose studied
1500–2300 mg — adequate intake to Chronic Disease Risk Reduction intake for adults, per NIH ODS.
Context
Population intake data and dietary guidelines are based on total sodium from food, not supplement sodium specifically, so there is little dedicated research on sodium as a standalone supplement ingredient.
