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 death from any cause from 44.61 to 39.28 events per 1000 person-years, corresponding to a 12% lower risk (rate ratio 0.88).
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 live longer — it could lower your chance of dying from any cause by about 12%.

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 that fewer of them died compared to those using normal salt. The numbers match the claim perfectly.
