High blood pressure

Blood pressure that stays high, which studies report as the change in the systolic and diastolic numbers.

Strongest evidence: Potassium, Fish oil and Omega-3 fatty acids.

What high blood pressure covers

One benefit that studies measure, and the supplements with the strongest evidence for each.

Blood pressure

The pressure of blood against the artery walls, written as systolic over diastolic in millimetres of mercury. Trials report the change in each number, and a few millimetres sustained over time is a meaningful change at the population level.
