Researchers at The George Institute for Global Health estimate that switching to potassium-enriched salt, which partly replaces sodium chloride with potassium chloride, could prevent 2.96 million deaths annually worldwide. The study assessed 193 countries and projects 10.17 million fewer new cases of cardiovascular and chronic kidney disease each year.
Why it matters
Around 1.4 billion adults worldwide have hypertension, and cardiovascular disease caused 19.2 million deaths in 2023. Excess sodium and insufficient potassium are established causes of high blood pressure, and the World Health Organization endorsed potassium-enriched salt in 2025 as a way to reduce that risk.
The modeled estimate of 2.96 million deaths prevented annually is compared against 19.2 million cardiovascular deaths recorded in 2023, but the figures assume full adoption that would require scaling up potassium chloride supply. Outcomes for people with advanced kidney disease or on certain medications, who may face hyperkalaemia risk, remain unaddressed in the projections.
The players
The George Institute for Global Health
A global health research organization that led the study estimating the mortality and disease impact of potassium-enriched salt across 193 countries.
World Health Organization
The United Nations agency for international public health that endorsed potassium-enriched salt in 2025 as a measure to reduce blood pressure and cardiovascular disease risk.
The details
The alternative looks, tastes and cooks like ordinary table salt, and the researchers examined scenarios covering household cooking salt, processed and restaurant food salt, and people already treated for high blood pressure. In Europe and North America, more than 70% of dietary salt intake comes from processed foods and restaurant meals, making industrial and food-service salt a major lever.
Timeline
- 2023: Cardiovascular disease caused 19.2 million deaths globally.
- 2025: The World Health Organization endorsed potassium-enriched salt to reduce cardiovascular risk.
- Every year: A global switch could prevent 2.96 million deaths annually.
Big Picture
The study builds on the World Health Organization's 2025 endorsement of potassium-enriched salt by putting numbers on the potential mortality benefit of wider adoption. It also shows that the largest gains would come from reformulating salt used in processed and restaurant foods, not only from household substitution.
For people managing blood pressure, a potassium-enriched salt may eventually offer a familiar-tasting way to reduce sodium intake without changing how food is cooked. Anyone with advanced kidney disease or taking certain medications should check with a clinician before switching, given the risk of hyperkalaemia.
The takeaway
Swapping regular salt for a potassium-enriched version is a simple change that could meaningfully lower blood pressure for many people, but it is not appropriate for everyone. Those with kidney problems or on certain medications should consult a doctor before making the switch.
