Has anyone proved his belief false, or have they merely shown poor support for his beliefs? I’d certainly say that Vitamin C SEEMS to help me cut a cold short, but I have to recognize that my own anecdotal experiences are far short of a well-controlled experiment.
With Vitamin C, a cold only lasts a week. Without it, a cold lasts 7 days.
My observations are anecdotal, but there is NO doubt that taking goodly quantities of Vitamin C cuts a cold short with my wife. The moment she starts feeling the scratchiness coming on, she doses up. The vast majority of the time, it never goes any further.
With me, it's not as effective as it is with her, but it does help some.

I’d take Barrett’s criticisms with a huge grain of salt (or Vitamin C).
