MrsD,
I struggled through the Thread, one-eyed, some interesting stuff in there. I checked my meds Patient Info Sheet - no contraindications with D from them, BUT increases absorbtion of Atorvastatin - Aaargh!

Kitt,

A good article which made me dig deeper. Some (about 35-40%) of UVA can penetrate plain window glass. This, I assume, is reduced by thickness, double glazing.

And Fortified foodstuffs and Supplementation are not as widespread over here as one would like to think. So figures are probably worse for us in general.

Dave.

I've been supplementing with D3 since end of 2006 when my sis brought this to my attention, she is challenged with MS....at that time I was feeling a lowness never thinking it was D deficiency. My lab came in at about 16 as I remember....got it up to 80 over a few years time and felt GOOD at 80, then went thru hip replacment in 2010 and that level dropped 40 pts with this surgery. I had read it could happen and sure enough it did. I have been working ever since to maintain 60+ Vit D.

Best to take K2 with D3 as this is the latest research...both are needed.

^^Vitamin K2? Hmm. I do not believe that that has popped up on my radar before. Thanks.

Here is a monograph on Vitamin K:

Thanks for the link, mrsD.

This is an interesting and thorough article, and I especially like the section on vitamin K and cardiovascular disease.

I also like the way this Institute formats their publications, so that you can check out the original studies that are mentioned via the footnotes.

It seems to me that the reviews on this site are fairly unbiased, but I believe you also said the same thing on a different thread.
