I just take a vitamin D supplement. It's not always sunny where I live and I don't have a lot of free time during the daylight hours to expose myself. lol
I take a regular multivitamin that has vitamin D in the morning. At night I take a calcium-magnesium supplement and take an additional vitamin D supplement with it. I think the calcium is like 1000 mg in that pill, the magnesium is like 400 mg, and the vit D is 400 mg as well.
I'm probably peeing most of all that out, but whatever.
No flu shot or H1N1 shot for me and so far, so good.
