Vitamin C’s role in preventing colds explained by immunology expert

What happened: Professor Dan Davis discussed the effectiveness of Vitamin C in stopping colds in a recent BBC Health interview. He provided insights into how Vitamin C interacts with the immune system.

Why it matters:

  • Many people take Vitamin C supplements hoping to prevent or reduce cold symptoms.
  • Understanding its actual benefits can guide better health choices and supplement use.

MNN Take: While Vitamin C is important for immune function, current evidence does not strongly support it as a guaranteed way to prevent or cure colds. It may help in some cases but is not a standalone solution.
