Vitamin C
for Cold & Flu
Regular vitamin C supplementation (200mg+ daily) for prevention, or high-dose during illness.
How it works
Vitamin C supports multiple immune functions including neutrophil and lymphocyte activity. During infection, plasma vitamin C is rapidly depleted by the metabolic demands of immune response.
What to watch for
Regular supplementation reduces cold duration by about 8% in adults (14% in children). Does not prevent colds in the general population. May reduce severity.
