Quercetin was discovered by the Nobel Prize winner Albert Szent-Gyorgyi. Quercetin, a zinc ionophore, is known for its antioxidant activity, antiviral activity, and more.

Quercetin has a number of great health-promoting benefits. Peer reviewed literature shows potential benefits of Quercetin include the ability to help reduce inflammation and to improve the immune system.

The scientific community has published a significant amount of research on quercetin, including clinical trials.

Zinc is found in cells throughout the body. It helps the immune system fight off invading bacteria and viruses. Zinc is essential for our immune system because it affects how our cells respond to infections. It can also help keep inflammation under control.

Zinc increases the activation of cells in the body that are responsible for fighting infection. It also activates enzymes that break down proteins in viruses and bacteria to reduce the chances of spreading.

Due to its direct antiviral properties, it can be assumed that safe zinc administration is likely beneficial for most of the population, especially those with suboptimal zinc status.

Vitamin D is essential to a healthy immune system as it initiates the adaptive immune response. It promotes the expression of a protein called cathelicidin which can promote the stimulation of T cells to help support an immune response. The link between vitamin D and viral infections was observed during winter months when vitamin D levels are generally lower.

Vitamin C, or ascorbic acid, is a water-soluble vitamin well known for its role in supporting a healthy immune system. Vitamin C contributes to immune defense by supporting various cellular functions of both the innate and adaptive immune system. Because our bodies cannot make vitamin C, it must come from the foods you eat every day.
