Quercetin plus Vitamin C

Ultra Absorption – Immune Support Formula*

For optimal cellular and immune support, we’ve combined quercetin with GammaSorb®, a unique delivery system shown to increase the absorption of certain hard to absorb (fat soluble) dietary ingredients, in some cases by as much as 8 times.*

  • Supports cellular and immune health
  • Helps maintain healthy sinus, lung, and respiratory function
  • Provides bioflavonoid and antioxidant support
  • Supports a healthy histamine response*†

Synergy that Delivers for Immune Support*

When you are looking for effective and powerful immune support, Quercetin plus Vitamin C provides two of the most highly regarded nutrients that consistently deliver.*

Quercetin Working at its Fullest Potential

While quercetin is well-known for its potential to support a healthy immune response, respiratory function, and healthy histamine levels, the fat-soluble flavonoid can also be difficult for the body to absorb.*

Vitamin C is An Essential Immune Nutrient*

Vitamin C is a key nutrient for healthy immune function. While this critical vitamin is available from foods, getting a consistent amount—as found in this formula—is best for reliable support every day. Vitamin C can also aid in quercetin absorption, making it even more effective.*

The result is a synergistic combination that helps you support a healthy immune function every day.*
