This says it all.

You want to know why you need a little UV exposure?

First, here is a chart by Dr. C. F. Garland showing the various diseases that we KNOW are affected by vitamin D levels.

According to Dr. Robert Heaney, a rule of thumb for vitamin D supplements is for every 1ng/ml you want to raise your serum 25(OH)D levels, you will need a daily dose of 100IU. So, a dose of 400 IU (the daily recommended intake currently) will increase your levels by 4ng/ml. If you are at a level of 25ng/ml, that puts you at 29ng/ml. If you look at the chart above, breast cancer risk is most effected by levels of 65ng/ml and above. That means, in order to get from 25ng/ml to 65ng/ml, you need 10 times the currently recommended dose (4000 IU).

Or, you could use a tanning bed 3 or 4 times a week.
