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.

Effective treatment

When I start to feel unwell with a common cold, I follow nutritionist Katie Young's regimen: Ester C (500mg) four times daily, Zinc picolinate (50mg), and a probiotic (50 billion). This unusual method works remarkably well, helping us feel better in just two days. Vitamin C boosts immunity, Zinc replenishes what we lose during illness, and the Probiotic creates a protective barrier in the digestive tract. We have tested this scheme with the entire family, and I highly recommend it.

I found that taking this vitamin at the onset of a common cold stops it in its tracks. A physician suggested taking 2000 mg on the first day, which worked for me, as the symptoms faded the next day. I'm glad I discovered this supplement.
