Vitamin supplements 'do us no good and may be harmful'

By Jeremy Laurance, Health Editor
Wednesday, 16 April 2008

We swallow them by the bucketload at great expense but there
is no evidence vitamin supplements do us any good, and they
may even be doing us harm, scientists have concluded. In a
blow to the multimillion pound dietary supplement industry,
a review of 67 randomised trials of vitamin pills has found
that far from prolonging life, they may actually shorten it.

These clowns wouldn't know evidence if it bit they in the arse.
A review based of poorly run trials results in poor conclusions.

The best thing one can do is to boycott items or services
that purchase adverts in the so-called "Independent."

What, you're saying the study is legitimate, therefore vitamins are useless?
Get a grip.
Merck did studies for their Vioxx.
These studies are engineered to produce the outcome they want.

They say,

"We found no evidence to support antioxidant supplements for primary
or secondary prevention. Vitamin A, beta-carotene, and vitamin E may
increase mortality."

But they didn't say they'd *found evidence* of the latter (that those
vitamins actually do increase mortality), just that they "may," without
explaining why they say so.

So is this newsworthy? Three authors did a meta-analysis and didn't
find evidence of anything, but they do advise the world that more
research is needed, and for the full article, they want money.

One of the ugly aspects of academic publishing is that in
order to get their work published, the authors have to
sign over copyright. They don't get a dime from reprints,
and in fact can't even reprint their own work for classes
or on their websites.

It better to publish in a journal that frees up the articles
after a year or choose an free e-journal. I'd say each
University should have its own it e-journals for it
professors with later maintaining some connection
to the articles with them retaining some rights of use,
rights to edit and improve, so on.

That might be changing soon. I think it's "Physics Review Letters"
(maybe not) which is reconsidering its policies right now.

That's why they reviewed 67 trials -- to average out
any particular studies with poor methodology.

A study isn't bad just because it reaches a conclusion
you don't like. Science often reveals information
that is surprising or disturbing.

If you disagree about that, please explain what error
was consistently being made in these 67 studies.
Reaching a conclusion you disagree with is not
an error.

This is a rehashed/republished meta-analysis that hand picks 67
out of some 7 or 8 hundred studies to reach to the
conclusion they want. It is a meaningless editoral,
the morons in the press seem think of as science.

Nor do we see any discussion of confidence intervals
and significant figures.

Maybe they say they do not work, but when I take them, I have more energy.

Great response everyone :-)

I bet those "researchers" will be visiting the soup kitchens
soon.

Likely a placebo effect. Feelings of "energy"
are not associated with any vitamin, unlike
something like candy bars which directly
contribute toward blood sugar.

That depends on how much you need them -- and at least two vitamins
(thiamine and cyanocobalamin) are generally considered "tonics," which
means they do make you feel like you have more energy.
