If vitamin D is a problem for you (as it is for nearly everyone in a northern climate), take the pills. It's impossible to overdose, you could down an entire bottle of vitamin D and be fine, if that's what you want. I'll continue to wear sunscreen at the beach and not be the guinea pig hoping decades of research on skin cancer is wrong, thank you very much!

You know how I know you didn't read it?

Yet vitamin D supplementation has failed spectacularly in clinical trials. Five years ago, researchers were already warning that it showed zero benefit, and the evidence has only grown stronger. In November, one of the largest and most rigorous trials of the vitamin ever conducted—in which 25,871 participants received high doses for five years—found no impact on cancer, heart disease, or stroke.
How did we get it so wrong? How could people with low vitamin D levels clearly suffer higher rates of so many diseases and yet not be helped by supplementation?
