I take a multivitamin on a daily basis. I do this despite knowing that the evidence shows that it’s unlikely to do me any good, though I’m healthily sceptical of the evidence that suggests it’s actively harmful (I think that this effect might reasonably be explained by confounders). I suppose my own behaviour is more of a habit than anything.
With that in mind, I was delighted to come across an article discussing this very topic in The Atlantic, written by none other than Professor Paul Offit, a well-respected paediatrician. In fact, as it turns out, the article is an extract from his book. In the extract, he gives a little of the history of the vitamin supplement history, and sets out the research evidence on the topic. But, more than that, he tells a truly engaging story, and leads one through it almost by hand. It’s a really great read!
