Has anyone tried these?
Seems like a great way to boost your levels without having your liver do so much work. A lot of us have compromised livers anyway, and perhaps that's tied into why we have low Vit D levels to begin with, even though we're supplementing. Wishclean, these may work for you, if you can't tolerate oral supplements at all. I'm going to get my levels tested soon and then try these, if I find that I'm deficient(and I most likely am). Getting sufficient Magnesium(organic/chelated) and Vitamin K2(MK4) could also be a huge part of this puzzle too.
I think it's interesting that when we're deficient in Vit D, we're given large amounts of Vit D2 to correct the deficiency, but this still leaves us with low Vit D3, which is what really matters in the end. So almost everyone who is diagnosed as deficient... is still deficient in the end. I'm interested in seeing what kind of results we'd be getting if our Vit D3 and blood Magnesium levels were up to snuff, while we supplemented with a bit of MK4 and Zinc(just a little) to properly utilize the D3.
I think there really is something to the Vitamin D3, but I think we should be more dilligent about how we go about raising our levels, making sure they're actually getting raised, and making sure we have other vitamins and minerals that we need to use the D3 to begin with.
