DEVA is proud to offer its new high-quality product that contains 500 mg of Quercetin + 25 mg of zinc along with Elderberry, Echinacea, and Oregano herbal extracts. Quercetin is a flavonoid pigment that is present in many fruits and vegetables. Quercetin appears to have the ability to chelate zinc ions and act as a zinc ionophore in the body. Zinc is an essential mineral that is involved in various aspects of cellular metabolism. It is also required for the catalytic activity of approximately 100 enzymes. A daily intake of zinc is required to maintain adequate levels because the body does not have a specialized zinc storage system. Deva Vegan Quercetin 500 MG is available for those who seek a quality Quercetin product that is combined with 25 mg of Zinc and, various botanical extracts such as Elderberry and Echinacea for their perceived benefits. DEVA Vegan Quercetin 500 MG is 100% animal-free, and guaranteed for purity, freshness, and labeled potency. Remember all DEVA Products are 100% vegan, vegetarian and are registered by the Vegan Society, the non-profit organization that actually invented the word "vegan".
