Vitamin C with Flavonoids: A Synergistic Formula for Immune and Antioxidant Support*

Thorne’s Vitamin C with Flavonoids is a foundational supplement that combines pure ascorbic acid with citrus-derived bioflavonoids. This synergistic blend is designed to support a robust immune response, promote collagen production, and provide potent antioxidant protection. The bioflavonoids work in concert with Vitamin C, enhancing its benefits and utilization in the body. It is an ideal choice for daily immune support and for promoting the health of skin, blood vessels, and connective tissues.*

How It Works: The Antioxidant Synergy

This formula leverages the complementary actions of Vitamin C and citrus bioflavonoids to provide a broad spectrum of health benefits.*

Enhanced Immune and Antioxidant Function
Vitamin C is a powerful antioxidant that is essential for the healthy function of white blood cells, which are the front line of the immune system. It helps to neutralize damaging free radicals throughout the body. The added Citrus Bioflavonoids are potent plant-based antioxidants themselves. They also help the body to regenerate and utilize Vitamin C more effectively, creating a powerful antioxidant duo.*

Support for Collagen, Skin, and Vessels
The body requires Vitamin C for the synthesis of collagen, the primary structural protein in skin, tendons, ligaments, and blood vessels. Adequate Vitamin C is therefore crucial for maintaining healthy skin elasticity, promoting efficient wound healing, and supporting the integrity of capillaries and blood vessels. Bioflavonoids further support this process by promoting healthy circulation.*

  • Combines Vitamin C with citrus bioflavonoids for synergistic benefit*
  • Provides potent antioxidant protection against free radical damage*
  • Promotes a healthy and responsive immune system*
  • Essential for the body’s natural production of collagen
  • Supports skin health and healthy blood vessel function*
