Key Benefits

  • Promotes optimal immune function.

  • Supports collagen production and liver detoxification.

  • With flavonoids for superior antioxidant benefits.

Vitamin C is essential for immune function, collagen synthesis, and liver detoxification, making it a cornerstone of overall health. As the body cannot produce vitamin C on its own, it must be obtained through diet or supplementation.

Thorne's Vitamin C with Flavonoids combines ascorbic acid with naturally occurring citrus flavonoids, enhancing its antioxidant properties. This powerful duo effectively scavenges free radicals, offering superior protection against oxidative stress. By incorporating Thorne’s Vitamin C with Flavonoids into your daily routine, you can support your immune health and overall well-being with a potent, synergistic formula.

Thorne sets the standard for excellence in the supplement industry. Recommended by over 100 professional sports teams and U.S. National Teams, Thorne offers a curated bundle of clean, science-backed supplements and treats designed to fuel your body naturally and effectively. With more than 30 years of dedication to quality, Thorne's commitment to purity and potency begins with sustainably sourced ingredients and rigorous testing. Every supplement undergoes four rounds of testing to ensure optimal absorption, safety, and efficacy, making Thorne the trusted choice for both health-conscious individuals and professionals.
