6 fruits that help control blood pressure

Watermelon contains an amino acid called citrulline.

The body converts citrulline into arginine, which produces nitric oxide that relaxes blood vessels, enhancing arterial flexibility.

These effects help blood circulation, which can lower high blood pressure.

A previous study found that adults with obesity and mild hypertension or prehypertension drank watermelon extract containing 6 grams of L-citrulline/L-arginine.

After 6 weeks, the participants recorded a decrease in blood pressure in the ankles, arm arteries.

In a small 2019 study, 27 volunteers drank watermelon juice or another beverage before exercising.
