Quercetin Complex Supplement

Quercetin Complex can be taken at any time of day that fits your routine.† Because some of the ingredients, like quercetin and bromelain, are better absorbed with food, it’s recommended to take the supplement with a meal.† Taking it consistently each day helps support antioxidant and overall wellness benefits.† If you are sensitive to supplements on an empty stomach, taking it with a larger meal may help reduce the chance of mild stomach discomfort.†

Quercetin is a plant flavonoid that may help support a healthy immune response by stabilizing mast cells†, which play a role in the body’s response to environmental triggers.† Vitamin C is included in the Quercetin Complex to further support immune health.†

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.  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 recommend taking Quercetin Complex separately from iron-containing supplements, such as standalone iron or multivitamins with iron.

Quercetin Complex Supplement was added to the physician-formulated line of Cooper Complete Nutritional Supplements to support immune health.† 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.

Quercetin has been studied for its antioxidant properties and cellular protection, which may support overall eye health.†

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

Quercetin may interact with digoxin, a prescription heart medication. If you are taking digoxin, consult your physician before using this product.

While some research has explored the effects of quercetin on blood pressure, results have been mixed. 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.† Our product is not intended to diagnose, treat, cure, or prevent any disease.

Cooper Complete Quercetin Complex contains Quercefit® Quercetin Phytosome, a phytosome-formulated quercetin shown in a small study to result in higher plasma quercetin levels compared to standard quercetin.† Quercefit® is formulated with the proprietary Indena Phytosome® technology, providing optimized quercetin solubility, proving up to 20-fold more bioabsorbed than unformulated quercetin, remaining in line with a diet rich in vegetables and fruits.†
