We investigated whether a daily vitamin C supplement could reduce the risk of catching colds. Over two months, 168 people took either the supplement or a placebo. Results showed that those taking vitamin C experienced significantly fewer colds and shorter durations of severe symptoms compared to the placebo group.

This supplement was well-tolerated with minimal side effects, and participants were notably satisfied with it. Overall, it seems that vitamin C may not only help prevent colds but also assist in faster recovery from them.

Ester C may reduce cold frequency

Van Straten M, Josling P. Preventing the common cold with a vitamin C supplement: a double-blind, placebo-controlled survey. Adv Ther. 2002;19:151.

We conducted a study involving 168 volunteers who were given either a placebo or a vitamin C supplement for 60 days during the cold season. Participants recorded their cold symptoms in a diary, and those on the vitamin C showed promising results.

The groups taking the active treatment reported significantly fewer colds and experienced fewer days of viral illness. Additionally, their severe symptoms lasted less time than those in the placebo group. Most volunteers experienced few side effects and enjoyed using the supplement, finding it more effective than prior vitamin C forms.

Overall, this vitamin C supplement could help prevent colds and ease symptoms, offering hope for better winter health.

Strengthens immunity

Most Useful Review

I bought these vitamins for my daughter, and despite the capsule size, she finds them easy to swallow. This is a repeat purchase as they effectively help with common colds. The Ester-C formula provides 1000mg of vitamin C, alongside other immunity boosters like vitamins A, D3, B-6, B-9, and B-12. The combination of ingredients also includes elderberry and echinacea, making it a great option for preventing colds. I give my child one capsule daily, while I take two for overall health.
