Dr. Mercola had an article a couple months ago on the importance of supplementing with Vitamin K2 if you’re going to supplement with Vit D3. Some studies showed that K2 helps keep calcium from being leached from your bones by the D3 and being depositied, among other places, in your arteries. So, that might explain the heart health issues that this study was finding.

FWIW, here's Dr. Cannell's formula: Purity Products. It contains K2.

Thanks! That is the correct form of K. Dr. Mercola claims we actually need about 200 mcg per day. Maybe I missed it, but I didn’t see the source of the K2, and I’m always interested in the source of each vitamin. I’m a skeptic on the safety of GM food and since soy (Natto) is a source of K2 I’d be afraid that they’re using conventional soy, which is probably GM. At this point foods aren’t allowed to be called organic if they’re GM.

Hmmm. Looks like a nice supplement but I’ve read not to take D and K at the same time of day as K inhibits D uptake.
