No Difference between the Efficacy of High-Nitrate and Low-Nitrate Vegetable Supplementation on Blood Pressure after 16 Weeks in Individuals with Early-Stage Hypertension: An Exploratory, Double-Blinded, Randomized, Controlled Trial

Randomized Controlled Trial

Human

2024 Sep 6

The study gave people either lots of nitrate-rich veggies or very few for 16 weeks and found that neither group had better artery flexibility than the other—so the claim that it doesn’t help is backed up.

Eating a little more nitrate-rich food each day—like spinach or beets—might help keep your arteries more flexible as you age, making your blood flow a bit easier.

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-rich supplements every day for a month can help people with high blood pressure have healthier blood vessels—making them more flexible and better at opening up to let blood flow smoothly.

If you have slightly high blood pressure and aren’t taking medicine, taking a daily supplement with a lot of nitrate from veggies doesn’t lower your blood pressure any more than taking a tiny amount — so more nitrate doesn’t help here.

If you have slightly high blood pressure and aren’t taking medicine, taking a high dose of nitrate from vegetable powder for 16 weeks doesn’t lower your blood pressure any more than taking a low dose—so more nitrate doesn’t help here.
