10 Questions
Ask a Question
Q:

Could quercetin help prostatitis?
A:

A small double-blind study of men with inflammatory or non-inflammatory chronic prostatitis found that 67% of the men who took quercetin (500 mg twice daily, for a total of 1,000 mg per day), had a significant overall improvement in their symptoms compared to the men in the placebo group.
Q:

Is it true that quercetin can impair iron absorption?
A:

Quercetin is a polyphenol found in abundant quantities in apples, citrus, onions, green leafy vegetables, coffee, and tea. Studies show coffee and tea can inhibit iron absorption, particularly the non-heme form of iron found in plants and grains. Plant forms of iron are as easily absorbed by the body as animal forms of iron. The recommendation for coffee and tea drinkers taking supplemental iron is to avoid these beverages for an hour before and after taking iron supplements. For this reason, we suggest Iron supplements (including multivitamins with iron) and Quercetin Complex be taken separately.
Q:

Do Cooper Clinic Physicians recommend Quercetin Complex?
A:

Yes. Emily Hebert, MD, Cooper Clinic Platinum Physician suggests daily supplementation of quercetin supplements to support a healthy immune system.
Q:

Why was Quercetin Complex Supplement added to the Cooper Complete line of dietary supplements?
A:

Quercetin Complex Supplement was added to the physician-formulated line of Cooper Complete Nutritional Supplements to support immune health function. The suite of Cooper Complete Immune Health Supplements also includes multivitamins, omega-3 fatty acids, vitamin C, vitamin D3, Turmeric Curcumin Complex, and the mineral zinc.
Q:

Does Quercetin Complex affect vision?
A:

Studies suggest Quercetin may support healthy vision by mediating sorbitol production†.
Q:

Where does the Quercetin in Quercetin Complex come from?
A:

The Quercetin in Cooper Complete Quercetin Complex is derived from seeds and pods of the dimorphandra mollis deciduous tree.
Q:

Can this product be taken in conjunction with the prescription digoxin?
A:

No. You should not take Quercetin Complex if you take the prescription medication digoxin.
Q:

Are there any potential drug interactions with Quercetin Complex?
A:

The Quercetin in Quercetin Complex may react with estradiol, immune-suppressive drugs, and calcium channel blocks. You must discuss this, and other supplements you take, with your physician or health care provider.
Q:

Could Quercetin Complex Supplement help my blood pressure?
A:

Research regarding the impact of quercetin has not been conclusive. A review and meta-analysis of seven trials found that taking 500 mg to 1,000 mg of quercetin daily reduced systolic blood pressure by approximately 3.04 mm Hg and diastolic blood pressure by 2.63 mm Hg, in people with and without high blood pressure.
Q:

I’ve heard quercetin can be poorly absorbed. How well is Cooper Complete Quercetin Complex absorbed?
