Latest vitamin research: a tough pill to swallow

skitched-20080419-151335.png



Thanks to Crabby for enlightening me to the latest drama around vitamins. Guess what: they might do us more harm than good.

The folks at Chochrane Systemic Review scrutinised 67 randomised trials but could “find no evidence to support taking antioxidant supplements to reduce the risk of dying earlier in healthy people or patients with various diseases.”

No wonder all that vitamin C I’ve been taking to squash my spring sniffles seems to be doing no good.

Says Chochran researcher, Goran Bjelakovic: ““The findings of our review show that if anything, people in trial groups given the antioxidants beta-carotene, vitamin A, and vitamin E showed increased rates of mortality. There was no indication that vitamin C and selenium may have positive or negative effects…The bottom line is that current evidence does not support the use of antioxidant supplements in the general healthy population or in patients with certain diseases.”

The news has sparked the expected outrage from the supplement industry, but journalists, too, are raising an eyebrow. The Times was quick to point out that studying the effect of antioxidants is incredibly hard due to our ever-changing diet patterns and unreliability as witnesses.


So what does this latest review mean for us? It certainly doesn’t mean that those of us taking multivitamins are going to suffer an early death – they were not covered in the review. For those of us who take supplements of individual antioxidants, the picture is still far from clear. What we can say is that if there are benefits in taking single antioxidant supplements, they are very small indeed.



I agree with the Guardian’s Sarah Boseley:


In the end, maybe the safest thing is just to eat a better diet.



I’m not about to give up my daily multivitamin, but it does make me think twice about all the £££’s I’ve spent on vitamin C. Next time I’ll spend my money on cauliflower and oranges, which are far more pleasant to eat than nasty pills!

    While I agree with eating a healtheir diet in general, go check out the information at the http://supplementinfo.org/index.php?src=blog&submenu=Blog&srctype=detail&blogid=23“ rel=”nofollow”>Dietary Supplement Information Bureau… they’re a good source of balanced information. For example, no just *any* supplement company can join, they’re very careful about their membership. Likewise, part of the information they provide is all about healthier nutrition, and which foods contain the best vitamins and minerals.

    The truth about the study in question is that they SELECTIVELY chose the 67 trials out of over EIGHT HUNDRED. Want to take a guess what the results of the OTHER 700+ trials were, as compared to these results?!?

    Nothing but more bias as far as I’m concerned
