The Claim
Among adults with a prior history of stroke, replacing regular salt with a salt substitute containing 75% sodium chloride and 25% potassium chloride reduces the risk of recurrent stroke by 14% (rate ratio 0.86) and reduces the risk of death by 12% (rate ratio 0.88), with greater reductions observed for hemorrhagic stroke (30%) and stroke-related death (21%), without increasing the risk of hyperkalemia.
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 to a special salt that has less sodium and more potassium might help keep you from having another stroke or dying from one — and it doesn’t seem to cause dangerous potassium buildup in your blood.

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 instead of regular salt, and found they had fewer strokes and were less likely to die — exactly as the claim says.
