Vitamin C

[Updownupdown]

This is worth reading:

To much anecdotal 'evidence' surrounding this subject but no hard evidence. As far as I'm concerned the only way to build immunity to a virus is through exposure i.e. catch it and get better.

Still, it's worth peddling the vitamin C myth if it means we get threads like this. I've just read it all: it's hilarious.

Nice link, you've got a few contributors thinking now Cotswoldrunner, see glucosamine thread. The thread on cramp is possibly funnier than vit C though, more unsubtantiated opinion and anecdote than you'd believe possible. Nothing I like better than an uncontrolled unblinded scientific trial N=1.

These health and injuries fora are worrying, do they reflect the hopelessness of education in science, poor health and science journalism or a failure of the healthcare profession? Perhaps the population are just desperate to believe semi mythical twaddle dressed up as fact, rather than current science. It sits easier in the mind than the reality of many uncertainties, unprovens and don't knows.

Sorry, I've probably offended a number of contributors in one fell swoop there.
