Extra Strong Dual-Action Immune Support^*
Quercetin and vitamin C are two of the most important immune-supporting nutrients in the world. With this formula, we’ve made them even more effective to help fortify your immune defenses every day.^*

Quercetin is highly regarded for immune support.^* However, quercetin is fat-soluble and very difficult for the body to absorb, which is why we’ve combined it with our unique GammaSorb^® delivery system. With GammaSorb, quercetin lives up to its fullest potential.

Vitamin C is a key nutrient for healthy immune function, so getting consistent levels is best for reliable, everyday support. As a bonus, vitamin C also aids in quercetin absorption, making it even more effective.^*

Frequently Asked Questions

How does GammaSorb^® work?

GammaSorb (gamma cyclodextrin) has been shown to improve the absorption of certain fat-soluble nutrients by enveloping them in a water-soluble shell. To be more specific, the gamma cyclodextrin plant-derived molecules surround fat-soluble ingredients in an open-ended microscopic structure, the exterior of which is water soluble. This exterior structure escorts the ingredients through the walls of the intestines and allows their fat-soluble contents to be more efficiently absorbed.

What is the source of quercetin in this formula?

Quercetin is widely available from many foods, including onions, apples, tea, berries, and grapes. However, there are other rich botanical sources, such as the flower buds from the Japanese Pagoda Tree (Sophora japonica), which provide the quercetin used in this formula.
