The Claim
Salt substitutes containing reduced sodium and increased potassium reduce systolic blood pressure by an average of 4.61 mm Hg and diastolic blood pressure by 1.61 mm Hg in adults, and this reduction is associated with a lower risk of cardiovascular events and death.
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.
Using salt substitutes that have less sodium and more potassium can lower your blood pressure a little, which might help you avoid heart problems and live longer.

What the research says
1 studyStudy: Effects of salt substitutes on clinical outcomes: a systematic review and meta-analysis
This study looked at salt that has less sodium and more potassium, and found it lowers blood pressure by the exact amounts claimed—and also reduces heart attacks and deaths. So yes, it supports the claim.
