The Claim
The methodological quality of the evidence supporting potassium’s effect on blood pressure is limited, with 7 out of 10 included randomized trials rated as having a moderate to high risk of bias, primarily due to unclear blinding and selective outcome reporting.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Most of the studies that looked at whether potassium lowers blood pressure aren’t very reliable—many didn’t properly hide who got the potassium or only reported the results they liked.

What the research says
1 studyThis study looked at how adding more potassium to your diet affects blood pressure, and it found it helps—especially if you already have high blood pressure. It also says we don’t have a lot of strong studies, which matches the claim that the evidence isn’t super solid.
