Natural Factors Quercetin 500 mg with Zinc & Copper is a synergistic formula that combines the antioxidant benefits of the bioflavonoid quercetin with essential minerals for enhanced support of the immune system. 

Quercetin is a potent antioxidant bioflavonoid found in small amounts in many plant foods, including herbs, fruits, and vegetables. Supplemental quercetin helps support cellular health throughout the body by counteracting unstable free radicals, and may provide seasonal allergy relief. Quercetin also helps zinc enter cells where the mineral supports the formation of antioxidant enzymes, such as superoxide dismutaste, to fight free radicals.

Zinc and copper are essential minerals needed by the body to support hundreds of enzyme reactions involved in the synthesis of proteins and other aspects of general health. Zinc is particularly important for healthy immune function as it is needed for both innate and adaptive immunity. As copper and zinc are antagonistic, supplementing these minerals together helps prevent imbalance.

Natural Factors Quercetin 500 mg with Zinc & Copper is an effective source of antioxidants and is specially developed to maintain immune health. It contains no preservatives, sweeteners, gluten, or GMOs, and is suitable for vegetarians and vegans. Quercetin is a great choice for anyone who wants to take a plant-based approach to self-protection and is a key addition to any health defence toolkit.
