Vitamin C May Be Effective Against Common Cold Primarily in Special Populations
I tried scanning the article but no luck - so who are in the special populations they are referring to?
Prophylactic vitamin C had no effect on common cold incidence:
Of 11,350 subjects, 6135 subjects used vitamin C for 2 weeks to 5 years.
Pooled RR for cold infection was 0.96 (95% CI, 0.92 - 1.00).
Subgroup analysis of 6 studies showed decreased cold incidence in subjects with extreme physical or cold stress or both (marathon runners, skiers, soldiers in subarctic exercise; RR, 0.50; 95% CI, 0.38 - 0.66).
Prophylactic vitamin C decreased duration of common cold:
In 7242 illness episodes in adults, pooled decrease in duration was 8.0% (95% CI, 3.0% - 13.1%).
In 2434 illness episodes in children, pooled decrease in duration was 13.6% (95% CI, 5.6% - 21.6%).
Prophylactic vitamin C slightly and inconsistently decreased severity of common cold:
Severity measured as days confined indoors or off from work or school decreased (P = .02).
Severity measured as symptom severity score did not decrease.
Pooled severity, measured as days off and symptom score, decreased (P = .004).
Treatment with vitamin C after onset of common cold did not decrease duration of symptoms in data from 3294 illness episodes:
In 1 study, illness duration of only 1 day was more common with vitamin C at 8 g/day vs 4 g/day (46% vs 39%; P = .046) and illness duration was shorter if treated with vitamin C within 24 hours of illness vs with other medications (3.6 vs 6.9 days).
Treatment with vitamin C after onset of common cold did not decrease severity of symptoms in data from 2753 illness episodes.
The effects of oral prophylactic vitamin C on the common cold include decrease in duration, especially in children; slight decrease in severity; and no decrease in incidence, except for a subgroup of persons exposed to extreme cold or physical stress.
Vitamin C treatment of the common cold has no significant effect on duration or severity of illness.
