All seven of the ingredients in this product have a synergistic relationship with other components. For example, the high quality vitamin K (MK-7) help with the absorption of the vitamin D (entirely from lichen) while the quercetin acts as an ionophore for the zinc. Zinc has been shown in many studies to be beneficial to the immune system and in treating colds and viruses. In order for the Quercetin to help as much as possible with the zinc, it needs the bromelain which makes it many times more absorbable into the body. The vitamin C also helps with Quercetin absorption, but it fills many other functions in the overall process due in large part to its antioxidant properties.
As a supplement website we are not permitted to make health claims but one needs only Google ‘Zinc Immune Support’ or ‘Zinc immune Oxford’ (and other world renowned schools) etc to see all the research done on this crucial element. We also sell a very similar product that contains Organic Elderberry Extract rather than Quercetin but it too includes Vitamin C, Zinc, Iodine and Vitamin D (slightly lower amounts of vitamins C and D but a higher level of Zinc as the majority of this other supplement is elderberry). The statements made regarding these products have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.
