The Claim

A linear dose-response relationship exists between increased potassium intake and reduced blood pressure in individuals with hypertension, with no evidence of a threshold or plateau effect within the studied range of 10–50 mmol/day.

Source: Effect of changes in potassium intake on blood pressure: a dose–response meta-analysis of randomized clinical trials (2000–2024)

What the research says

Supports is higher

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

Supports

Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

If you eat more potassium-rich foods, your blood pressure goes down in a straight-line way—more potassium means lower blood pressure, and this keeps happening all the way up to a pretty high amount, at least for people with high blood pressure.

What the research says

1 study
  1. Study: Effect of changes in potassium intake on blood pressure: a dose–response meta-analysis of randomized clinical trials (2000–2024)

    This study found that when people with high blood pressure eat more potassium, their blood pressure goes down in a steady way—more potassium means more drop, with no sign that the benefit stops even at the highest dose tested.
