The Claim

Chronic consumption of red beetroot juice has no significant effect on endothelial cell NADPH oxidase protein expression in middle-aged and older adults with overweight or obesity.

How it works
1 study reviewed
In plain English

Drinking red beetroot juice regularly does not change the levels of NADPH oxidase protein in the lining of blood vessels in middle-aged and older adults with overweight or obesity.

See the scientific wording

In middle-aged and older adults with overweight or obesity, chronic consumption of red beetroot juice does not reduce endothelial cell NADPH oxidase protein expression, indicating no significant effect on vascular oxidative stress pathways.

Why this might work

Drinking beetroot juice daily increases nitrate in the blood, which turns into nitric oxide through bacteria in the mouth and chemical reactions in the body. This nitric oxide relaxes blood vessels, but it does not reduce the amount of NADPH oxidase protein in the lining of blood vessels. Because NADPH oxidase keeps producing harmful molecules that destroy nitric oxide, the nitric oxide levels rise but the underlying oxidative stress stays the same.

  1. Study: Impact of Red Beetroot Juice on Vascular Endothelial Function and Cardiometabolic Responses to a High-Fat Meal in Middle-Aged/Older Adults with Overweight and Obesity: A Randomized, Double-Blind, Placebo-Controlled, Crossover Trial

    People who drank beetroot juice daily for four weeks didn't show any improvement in blood vessel function, even though their bodies had more nitrate — which is supposed to help. This suggests the juice didn't reduce the harmful oxidative stress in their blood vessels.
