Participants consumed two 2.3-ounce bottles of concentrated beet juice, followed by one bottle every morning for 7 days. After several weeks, they consumed beet juice menu without nitrate.
To measure vascular function, researchers analyzed blood vessel expansion. When participants were and were not drinking the beet juice with nitrate.
Results showed that drinking the beet juice with nitrate daily improved blood flow in comparison to the nitrate-free UFABET
However, the researchers found that neither treatment stopped the decline in blood vessel function. After tissue damage had occurred in postmenopausal women.
The results also suggest that certain protective benefits nitrate on blood vessels disappear within 24 hours after the last dose. Consistent daily or even more frequent intake of nitrate-rich beetroot juice might be necessary to maintain the protective effects on endothelial function.
This was a small, short-term study. Larger, long-term studies are needed to find the best dose. And timing of nitrate intake to promote blood vessel function and heart health in postmenopausal women.
“Postmenopausal women have a higher risk of cardiovascular disease. Because they lose the protective effect of estrogen on vascular function and nitric oxide production. Which normally keeps the arteries flexible, fluid, and resistant to plaque formation.” said Higgins. “Other effects of age include postmenopausal women [who] are less active in general and gain weight, both of which are unhealthy.”
