Quercetin benefits

The purpose of 7EN is to combine multiple synergistic ingredients known for their antiviral properties. Each component in E7 relies on other components. The goal is to create a food-based immune support multivitamin with proven ingredients. We want to provide consumers with the best vitamin for the current time.


Quercetin has been shown in early studies to block viral replication. It is a flavonoid, found in several vegetables. Studies suggest that Quercetin supplementation may have antioxidant and anti-inflammatory effects. Quercetin has been studied in various types and models of viral infection due to its promising antiviral effects in inhibiting polymerases, proteases, reverse transcriptase, suppressing DNA gyrase, and binding viral capsid proteins. Quercetin has also been shown to inhibit in vitro production of cyclooxygenase and lipoxygenase which are typically induced by inflammation. So the hypothesis is that is can work for viral replication similarly to how it works for inflamation. Quercetin was initially selected as the main ingredient to act as an ionophore for zinc.

Roles of Zinc and Other Key Ingredients

Zinc can help protect us from viruses in two ways. The first way is by blocking viral entry via the lungs. It can also protect the inside of cells from viral replication. A main purpose of quercetin is to act as an ionophore and assist zinc in passing through cell walls. The NIH writes about these antiviral benefits as well.

Just as zinc needs quercetin, quercetin needs several of E7’s ingredients in order to be absorbed by the body. Both vitamin C and bromelain increase quercetin absorption. Our bromelain comes from pineapples and vitamin c has health benefits by itself.

A similar synergy comes from the amounts of vitamins D and K found in our Essential 7 multivitamin. These two vitamins make each other more effective in the body according to several articles on the NIH website. We use MK-7 which is the most absorbable form of vitamin K. All of our vitamin D3 comes from lichen. VItamin D is also a well known anti viral vitamin shown in several studies to protect against covid-19 illness.

Japan has the oldest population on Earth yet still have one of the lowest Covid death rates. Japan also consumes as much iodine via diet as anyone else. The Japanese consume a lot of kelp. This product contains 100% RDA of iodine via kelp. Iodine is one of the main building blocks of hormones in the thyroid. The thyroid gland is a vital hormone gland. It plays a major role in the growth, development and metabolism of the human body.

Quercetin and zinc studies for covid-19

I created this product to provide an immune support supplement containing many anti viral ingredients. Doctors and pharmacists were among the first to order it due to its strong combination of ingredients. This website does not make medical claims, but a search of any ingredient produces endless data on the benefits of these components.
