It takes a while for levels to go up, so give it some time to re test. What's astounding to me is, some do require injections of 100K + IUs for a time to get those levels up, then an oral dose to keep them there. I know a few people that had to go that route to get their levels up to where they should be per chart in the article. Me, 5k IU per day and I'm GTG, and the majority seem to be similar, but there's only on way to actually know. There's genetic differences too it seems as African Americans and Asians seem to have more difficulty with that. The doc mentioned before is Korean.
Will,
Any particular liquid D3 you would recommend?
(Preferably a 10,000 IU dose.)
I had one brand that worked for me but for some reason it is no longer produced.
