The Claim
Among adults aged 60 or older with a history of stroke or hypertension, replacing regular salt with a salt substitute containing 75% sodium chloride and 25% potassium chloride reduces the rate of stroke from 33.65 to 29.14 events per 1000 person-years, corresponding to a 14% lower risk (rate ratio 0.86).
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're over 60 and have had a stroke or high blood pressure, switching to a special salt that has less sodium and more potassium might help you have fewer strokes.

What the research says
1 studyStudy: Effect of Salt Substitution on Cardiovascular Events and Death.
This study gave older adults with high blood pressure or past strokes a special salt that has less sodium and more potassium, and found they had fewer strokes than those using normal salt—exactly as the claim says.
