Effects of salt substitutes on clinical outcomes: a systematic review and meta-analysis

Surprising Findings
The blood pressure-lowering effect was consistent across all subgroups — including those with normal baseline blood pressure.
Most interventions only help people who are already high-risk, but this worked even in healthy people — suggesting prevention works better than we thought.
Practical Takeaways
Switch your table salt to a potassium-enriched salt substitute (like 75% NaCl, 25% KCl) to potentially lower your blood pressure.

If you swap out regular table salt for a special salt that has less sodium and more potassium, it might help you have fewer strokes, heart problems, and even live longer — plus it could gently lower your blood pressure.
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.
If you replace some of the regular salt in your food with a salt substitute that has less sodium, your blood pressure might drop a little — about 1.5 points for the top number and 1 point for the bottom number for every 10% less salt you use.
Using salt substitutes instead of regular salt might help adults live longer and have fewer heart problems like heart attacks or strokes.
Using salt substitutes helps lower blood pressure in pretty much everyone—no matter how old they are, whether they're male or female, how high their blood pressure started, or where they live.
