What is Quercetin?

Quercetin is a bioflavonoid widely distributed in the plant kingdom.

Quercetin can inhibit tumor, fight free radicals, fight oxidation, inflammation, anti-allergy, reduce blood pressure, reduce blood lipids, prevent diabetes complications and immunomodulatory functions, and has important significance for the treatment and prevention of cancer, aging and cardiovascular diseases.

The food source of Quercetin
The best dietary source of Quercetin is Onions. Eating just one large onion, raw or cooked, is enough to significantly boost Quercetin levels in the body within a few hours. Apples also contain Quercetin, but the body does not absorb it effectively. We can absorb about half of the Quercetin found in Onions, but only 30 percent of the Quercetin found in apples. If you want Quercetin to help prevent disease,
The amount required is quite high, so Quercetin supplements should be taken.

Quercetin and pulmonary nodules
A study conducted at The Maastricht University School of Medicine in the US conducted a double-blind intervention in two groups of patients with nodules of similar age and sex, who were non-smokers and had never been treated.

Quercetin supplementation improved antioxidant defense, indicating an increase in total plasma antioxidant capacity. In addition, quercetin supplements 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 greater the effect of quercetin supplements.

Quercetin and chronic pulmonary obstruction

A randomized, double-blind, placebo-controlled trial conducted by the lung disease institute at the university of Michigan divided patients with chronic pulmonary obstruction who had smoked for 10 years or more into placebo, 500mg quercetin, 1000mg quercetin, and 2000mg quercetin for 6 months.

There were no serious adverse events or significant adverse changes in lung function in any group. Quercetin supplementation was effective in reducing disease severity in subjects with chronic obstructive pulmonary disease. Patients with chronic pulmonary obstruction are advised to take quercetin supplements as a first step in their treatment.

Quercetin and cancer

Quercetin has shown great promise in the treatment and prevention of cancer. Quercetin has shown value in the treatment of leukemia, lung, breast, colon and ovarian cancer.
Several studies in mice have shown that:
Protective effect of Curcumin and quercetin mixture on the development of lung cancer in mice.
Another study on lung cancer showed:
Morphological and histological analysis of lung tumor nodules confirmed that the prophylactic treatment of Curcumin and quercetin induced apoptosis of lung tumor cells by regulating p53.

Quercetin usage and dosage

Take 300 to 600 milligrams of quercetin a day as a basic preventive dose to prevent heart disease and cancer. Additional doses should not exceed 600mg in a single session or 1200mg throughout the day when needed.
