Vitamin C is perhaps the most popular vitamin known to man. It is consumed in a supplemental form by millions of people across the world for its antioxidant properties, which are well-documented in medical research. C-1000 provides a potent dosage of this key vitamin and is blended with Rose Hips and Bioflavonoids, which are natural synergists to Vitamin C.*

From the FDA's website: "Some scientific evidence suggests that consumption of antioxidant vitamins may reduce the risk of certain forms of cancer. However, FDA has determined that this evidence is limited and not conclusive."
