Thorne Bestseller

Free of Additives

Thorne’s Vitamin C with Flavonoids does not contain corn starch, as many other vitamin C supplements do.

Bioflavonoids spare vitamin C, providing greater antioxidant capacity.*

Unique Formula

Vitamin C with Flavonoids contains ascorbic acid and citrus flavonoids replicating the way these nutrients are found in nature.

Trusted Manufacturer

For more than 30 years, Thorne has been trusted by health-care practitioners who prescribe our products to their patients. Thorne products are a testament to Thorne's mission to provide high-quality supplements that are tested for quality, safety, and efficacy.

Immune Support

Proper nutrition keeps the body's defenses healthy.

Sourcing Exceptional Ingredients

Thorne cares deeply about where our ingredients come from. We partner only with suppliers whose practices emphasize quality, science, and responsibility. Better ingredients means better potency, absorption, and digestibility - and ultimately better health.

Manufacturing the Right Way

We manufacture our own products to ensure full supply chain transparency. For more than 30 years, we have invested in clean manufacturing practices. We refuse to use ingredients that can inhibit absorption. We perform our final production in the United States.

Four Rounds of Testing

We run four rounds of testing for each of our products. We have invested in two state-of-the-art in-house laboratories that allow us to conduct four rounds of testing, while most competitors test only one or two times. We test our raw materials, in-process batches, finish products, and product stability for each product.

Thinking Sustainably

We're thinking sustainably to protect our environment. We believe the environment should never be compromised for the sake of business gain.
