Immune Support and Healthy Histamine Response Formula with Vitamin C*†
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.*
More Quercetin + Superior Absorption = Optimal Benefits
Quercetin Extra Strength features even more immune-supporting quercetin compared to our original formula.* This amazing nutrient is combined with GammaSorb, which has been shown to increase the absorption of certain hard to absorb (fat soluble) dietary ingredients, in some cases by as much as 8X.
