Replacement of dietary sodium chloride with a potassium-enriched salt substitute (75% NaCl, 25% KCl) reduces stroke incidence, major cardiovascular events, and all-cause mortality, while modestly lowering blood pressure.

Study: Effect of Salt Substitution on Cardiovascular Events and Death.

This study gave people a special salt that has less sodium and more potassium, and found they had fewer strokes, heart problems, and deaths compared to those using regular salt — without dangerous side effects.

Study: 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, and found they had fewer strokes and were less likely to die compared to those using regular salt — proving the salt swap works.

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

This study looked at replacing regular salt with a mix that has less sodium and more potassium, and found it lowered blood pressure and reduced heart attacks, strokes, and deaths — exactly what the claim says.

Study: The contribution of sodium reduction and potassium increase to the blood pressure lowering observed in the Salt Substitute and Stroke Study

This study tested a special salt with less sodium and more potassium, and found that people who used it had fewer strokes, heart problems, and deaths — just like the claim says. It also found that the extra potassium, not just less salt, was mostly responsible for the health benefits.
