The Claim

A potassium intake of 90–120 mmol/day is associated with the greatest reduction in systolic blood pressure (7.16 mm Hg) and the lowest stroke risk, with no additional benefit observed at higher intakes.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Eating the right amount of potassium—between 90 and 120 millimoles a day—seems to lower your blood pressure the most and cut your risk of stroke the most; eating more than that doesn’t help any further.

What the research says

1 study

  1. Study: Effect of increased potassium intake on cardiovascular risk factors and disease: systematic review and meta-analyses

    This study found that eating more potassium — especially between 90 and 120 mmol per day — lowers blood pressure the most and reduces stroke risk, and eating even more doesn’t help any further. That’s exactly what the claim says.
