“Don’t waste clean thinking on dirty data.”
For decades we have been trying to understand the effects of vitamin C on the immune system. Linus Pauling wrote Vitamin C and the Common Cold in 1970, and sometimes it feels like we haven’t made any progress.
The best and most comprehensive analysis of the data at hand, collected from decades of research studies, shows that vitamin C has some effect on the common cold – but it is very limited.
This has led many to conclude that taking vitamin C to ward off a cold just isn’t worth it. Is this the final word on the subject?
Short answer: not even close.
