The Claim
In adults with a prior stroke, the use of a salt substitute containing 75% sodium chloride and 25% potassium chloride is associated with a mean reduction in systolic blood pressure of 2.05 mm Hg compared to the use of regular salt.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you've had a stroke before, switching from normal salt to a special salt that has less sodium and more potassium might lower your blood pressure by about 2 points — not a lot, but maybe helpful.

What the research says
1 studyStudy: Salt Substitution and Recurrent Stroke and Death: A Randomized Clinical Trial.
This study gave people who had a stroke a special salt with less sodium and more potassium, and found their blood pressure went down by about 2 points — just like the claim said.
