Surprising Findings
All three metabolites inhibited VCAM-1 surface expression at 2 μmol/L, despite being less effective overall.
Most people assume metabolites are inactive waste products — but here, even the weakest forms still blocked one critical signal at a realistic body concentration.
Practical Takeaways
Eat more quercetin-rich foods like apples, onions, capers, berries, and green tea daily.

Flavonoids, which are natural compounds in fruits and veggies, help keep your arteries clean by stopping white blood cells from sticking to artery walls and turning bad cholesterol into plaque.
When your body breaks down quercetin (a plant compound in foods like apples and onions), the resulting molecules aren’t as good at calming down inflammation in your blood vessels as the original quercetin — but they still work a little bit, especially at stopping one specific inflammation signal at a common dose.
A natural compound called quercetin, found in foods like apples and onions, may help calm down inflammation in blood vessels by reducing the stickiness of the vessel lining, which could prevent white blood cells from sticking and causing damage.
A natural compound found in foods like apples and onions, called quercetin, might help calm down inflamed blood vessels by reducing a signal that attracts immune cells — potentially helping to prevent artery damage.
