Update on vitamin d. I just found out that moderate sun exposure can give you a vitamin d dose of between 10,000, and 20,000 units a day. And 4000 units a day causes prostrate cancer shrinkage. So taking more than I recommended earlier seems fine.

Food sources of vitamin d3 are fatty fish, sardines, cheese, and egg yolks.

So get a little sun. Get some in food. Take a supplement. I would stay under 4,000 units a day on the supplements. Take with fat.
