More information about pure quercetin powder

The best dietary source of quercetin is onions. Eating one large onion, raw or cooked, is enough to significantly increase quercetin levels in the body within a few hours. Apples also contain quercetin, but the body cannot absorb it effectively. We can absorb about half of the quercetin in onions, but only 30% of the quercetin in apples.

A study from the Maastricht University School of Medicine in the United States conducted a double-blind intervention experiment on two groups of patients with nodules of similar age and sex, non-smoking and never received related treatment, and found that:

Quercetin supplementation improved the body's antioxidant defenses, indicating an increase in total plasma antioxidant capacity. In addition, quercetin supplementation reduced markers of oxidative stress and inflammation in the blood of patients with sarcoidosis. And the higher the levels of oxidative stress and inflammatory markers, the more pronounced the effect of quercetin supplementation.
