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.*

Features Our Exclusive GammaSorb® Delivery System
GammaSorb is a proven delivery system which consists of gamma cyclodextrin. GammaSorb has been shown to increase the absorption of certain hard-to-absorb (fat-soluble) dietary ingredients. A plant-based oligosaccharide, the gamma cyclodextrin surrounds hard-to-absorb and fat-soluble ingredients in an open-ended microscopic structure, the exterior of which is water-soluble, helping to escort the nutrients through the lining of the intestines and into the bloodstream.*

FAQ
Frequently Asked Questions
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.
