Quercetin is a naturally occurring flavonoid found in a multitude of foods such as fruits, vegetables, grains, legumes, tea & wine. It possesses many potential health benefits including antioxidant, Anti-Inflammatory, Anti-Histamine, Anti-Microbial & Immune Modulating effects.
Quercetin is usually well tolerated & is often used in allergies, viral infection, neurocognition, cardiovascular disease and diabetes mellitus.
Dosage: 200-1500mg/day. Talk to a health care practitioner about the recommended dose for your condition.
On its own, quercetin has a low bioavailability, which means your body absorbs it poorly, so taking it with other compounds such as vitamin C and bromelain may help to increase it’s absorption.
Other immune enhancing & antiviral supplements include – vitamin C, zinc, vitamin D, vitamin A, astragalus, echinacea & medicinal mushrooms.
While there is generally little to no side effects, some may experience mild symptoms like headaches, stomach aches, or tingling sensations when taking more than the recommended therapeutic dosage. Avoid if you are pregnant or breast feeding.
