Best Quercetin Supplement 100mg (30 Veg Capsule)

Quercetin is a plant pigment (flavonoid). It's found in many plants and foods, such as red wine, onions, green tea, apples, and berries.

Quercetin has antioxidant and anti-inflammatory effects that might help reduce swelling, kill cancer cells, control blood sugar, and help prevent heart disease.

Quercetin is most commonly used for conditions of the heart and blood vessels and to prevent cancer. It is also used for arthritis, bladder infections, and diabetes, but there is no strong scientific evidence to support most of these uses.

The flavonoid Quercetin is not the same as CoQ10. As mentioned above, quercetin is a dietary flavonoid found in numerous fruits and vegetables, particularly onions, kale, and chilli peppers. Coenzyme Q10 (CoQ10) is a biologically active quinone that plays a vital role in the mitochondrial electron transport chain.

Quercetin is found in many fruits and vegetables and is safe to consume. As a supplement, it appears to be generally safe with little to no side effects. In some instances, taking more than 1,000 mg of quercetin per day may cause mild symptoms like headaches, stomach aches, or tingling sensations.

Studies have found that taking quercetin for at least 5 consecutive days can minimise instances of sneezing, and significantly reduce nasal itching, helping sufferers to live a more comfortable life.

Quercetin is an antioxidant found naturally in onions, apples, and other produce. Research has demonstrated the antihistamine effects of quercetin. A 2007 study found that it even lessened the respiratory side effects of allergies in rats by reducing the inflammatory response in the airways.

Quercetin has been safely used in amounts up to 500 mg twice daily for 12 weeks. It is not known if longer-term use or larger amounts are safe. Quercetin can cause headaches and tingles in the arms and legs. Very high doses might cause kidney damage.
