According to The Studies Show, there is no solid evidence that Vitamin D supplements do anything good for you, the only exception being if you have a condition which causes you to have an actual deficiency. So no magic after all, not even a little bit. They were very approving of the large RCT (N=26,000) still being reported and published after a null hypothesis finding. It is the one separate vitamin I have been taking, and I likely will continue to the end of the bottle, because why not?
I admit I'm a bit disappointed.
But there are new claims every day!

Vitamin D supplements stopped my doctor telling me that my Vitamin D levels are slightly low when I get my blood labs done...
ReplyDeleteNot sure that's worth the cost of the supplement bottle.
12-16 nanograms per milliliter is normal, but some people get excited by higher levels and consider anything below 20 "insufficient." But it isn't.
ReplyDeleteHaving your doctor not bother you is a positive that is worth a few bucks, yes.
Like no kidding, every day.

Grim, I looked at both of those superficially and it seemed they did not make all the connections in the chain. There seemed to be assumptions that were unsupported.
ReplyDeleteI could be dead wrong on that. Those assumptions might be universally greed upon by other researchers, so they didn't bother to put forward the evidence here. You could try the transcript of the podcast on my sidebar and see what you thought.
I looked at the transcript. They have a good point about the xkcd cartoon, which often is helpful and clever. And no doubt there are many places where claims have been made that aren't true. I just raise the issue of the frequency of findings in a kind of 'where there's smoke, there's fire' sense. All the claims may not be true; most of them may not be. Maybe only two or three will turn out to be out of the hundreds that are made. But it continues to be of interest, and continues to produce new suggestive findings of benefits on a regular basis.
