The Claim

The antiviral effect of sodium chloride requires intracellular chloride ion transport rather than sodium ion transport, as chloride channel inhibition with NPPB reverses viral inhibition while sodium channel inhibitors (ralfinamide, benzyl amiloride) do not affect NaCl-mediated antiviral activity.

Source: Antiviral innate immune response in non-myeloid cells is augmented by chloride ions via an increase in intracellular hypochlorous acid levels

What the research says

Roughly balanced

Support and challenge are close. The picture may shift as more studies come in.

Supports
5score
Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Salt's ability to fight viruses depends on how chloride moves inside cells, not sodium. When chloride movement is blocked, salt can't stop viruses, but blocking sodium movement doesn't change salt's virus-fighting power.

See the scientific wording

The antiviral effect of sodium chloride requires intracellular chloride ion transport rather than sodium ion transport, as chloride channel inhibition with NPPB reverses viral inhibition while sodium channel inhibitors (ralfinamide, benzyl amiloride) do not affect NaCl-mediated antiviral activity.

What the research says

1 study

  1. Study: Antiviral innate immune response in non-myeloid cells is augmented by chloride ions via an increase in intracellular hypochlorous acid levels

    The study shows that salt's antiviral effect relies on chloride ions moving into cells, not sodium ions, because blocking chloride channels stops the effect but blocking sodium channels doesn't—just like the claim says.
