I take 8000 to 10,000 units of vit D daily and have for about three years now. I haven't had a cold - not even the winter sniffles for the last two years. Had a physical this year and my vit D level was right in the MIDDLE of the healthy range.

So that's how much it took to get to that level. I also avoid the sun because I hate age spots. Wrinkles and gray hair are ok but age spots are gross :)

I too have to take 10,000 or more to keep my levels as high as I want them. Anyone with anything chronic may well need to get closer to 80 on the blood test. If I had cancer I would want it just under 100. Yes, D fights cancer. No one on with cancer should go without supplementing D.
