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.
