Eating a little more nitrate-rich food each day—like beets or spinach—can help your blood vessels work better, making them more flexible, and this happens even if your blood pressure doesn’t drop.

Eating more nitrate-rich vegetables for 16 weeks doesn’t lower blood pressure or make arteries stiffer in people with early high blood pressure—so it doesn’t help these heart health markers in the short term.

Taking nitrate supplements for 16 weeks doesn’t seem to change cholesterol, good/bad fats in the blood, or inflammation markers in people with early high blood pressure—so it doesn’t help those things in this group.

Taking nitrate-rich supplements every day can lower blood pressure just as much in people who aren't on blood pressure meds as in those who are—meaning it might help even more on top of their regular medicine.
