All seven of the ingredients in this product have a synergistic relationship with other components. The high quality vitamin K (MK-7) helps with the absorption of the vitamin D3 (entirely from lichen). Meanwhile, the quercetin acts as an ionophore for the zinc. Zinc has 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.
Immune Support Ingredients
One needs only Google ‘Zinc Immune Support’ or ‘Zinc immune Oxford’ etc to see all the research done on it. 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). This product is not intended to diagnose, treat, cure, or prevent any disease.
