I take 4000 IU of Vit D a day - I hate the sun, even though I know it's superior to supplementation.
I also take a prenatal vitamin b/c I'm pregnant. When I wasn't pregnant I took half a dose of the pre-natal most days...my nutrition is pretty good but I feel like this helps cover my bases for times when I go off the rails a bit.
Take Natural Calm most nights b/c it really does help me sleep. Before I got pregnant I just did the magnesium...now I take the mag/calc combo on the recommendation of my midwife. It has helped with my restless legs quite a bit.
