Using salt with more potassium might lower blood pressure the most in people who usually eat very little potassium but a lot of salt—like some adults living in rural China.

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

Computational/Algorithm Study
2024 Apr

The study gave people a special salt with more potassium and found that their blood pressure dropped mostly because of the extra potassium—not less salt—and this worked best in people from rural China who usually eat too much salt and not enough potassium.

Similar Assertions

When people who don’t eat much potassium switch to salt with extra potassium, their blood pressure drops mostly because they’re getting more potassium—not because they’re eating less salt, since they’re still eating plenty of salt.

If you eat less salt but add more potassium to it, your blood pressure might drop more if you usually don’t get much potassium in your diet—because your body gets a bigger boost from the potassium than it loses from the sodium.

If people eat less salt and more potassium-rich salt, the extra potassium might lower their blood pressure more than cutting back on salt alone — and most of that drop seems to come from the potassium.

When mice eat a lot of salt, adding a moderate amount of potassium lowers their blood pressure, showing that potassium's main benefit might be fighting high blood pressure caused by salt.

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.
