This study doesn't mean much to me. I started taking Vitamin D as soon as I heard about it being of benefit ... early last year.

My reading of the literature showed that Vitamin D is useful for so many health effects due to its many interactions. Being low in general isn't a good idea. I'm in direct sunshine for around 2 hours a day. White skin with a tan. So I chose a dosage that shouldn't cause imminent death and then a few weeks after I got a full blood test. Mainly to confirm that side effects of too much vitamin D weren't taking hold. Surprisingly even with taking the capsule once a day I found I was still low. So the doctor upped my amateur considered dose to his recommendation.

Get your own blood tested and confirm for yourself. Leave the anti-vitamin people to themselves. I got repeatedly criticized for supplementing. People quickly shut up when you show your blood results.

I realise anecdata is fun to mock, but in my sample size if I'd seen a study like this and fully believed it then maybe I wouldn't have done the blood test. I wonder how many other people are low in vitamin D and have no clue.
