Vitamin C

Alternative Names: Emergen-C 1,000mg Vitamin C Supplement, Super Orange, Nature Made 1000 mg Vitamin C Tablets, Nature's Bounty Vitamin C 1000 mg

Vitamin C (ascorbic acid) is a water-soluble vitamin and antioxidant commonly used for immune support during the common cold. While it does not reliably prevent colds in most people, regular daily use may slightly shorten the duration and reduce the severity of symptoms, typically by about half to one day. Starting vitamin C after symptoms begin has limited benefit. It is taken orally (tablets, capsules, chewables, or powders), commonly at doses of 200–1,000 mg daily, and is generally well tolerated, though higher doses can cause stomach upset or diarrhea. Vitamin C is best considered a low-risk, supportive treatment, not a cure.

The evidence for vitamin C in upper respiratory infections is mixed, with most studies showing minimal overall benefit, particularly when started after symptoms begin. That said, it is low cost, widely available, and has a strong safety profile at typical doses. For patients looking for a low-risk option that may provide a small reduction in symptom duration or severity, vitamin C is reasonable to consider as an adjunct during a URI, with appropriate expectations.
