Thanks for your reply, chiron :) Yeah, all my info comes from getting to know the vitamindcouncil webpage good and well, and it doesn't deviate from what we're told here on Curezone one whit. There are folk who can't do vitamin D3 because of major mineral imbalances and long-existing toxicities (like heavy metals.. they get bad pains when they go high on D3), and beyond that, folk who can't even absorb it, because they are low on CoQ10 from quality red meats and organ meats.
I second your suggestion of a himalaya salt bath, that is an excellent way to ease things.
