I am still taking prenatal vits (which include Vit D) as and when I can, they have always made me feel ill. Anyone else get that? It was the same last time around to, they just make me feel really queazy and I've tried a few brands.
I tend not to worry (maybe wrongly so) about the whole vit D thing as we live in the south and spend an awful lot of time outside, regardless of season. My general understanding is that, if you spend a ton of time outside over the summer, and a reasonable about of time outside over the rest of the year, you should have reserves enough to deal with the winter. Of course if, for whatever reason, you can't get out much and/or you live in the north of Scotland where you really do get next to no light during the winter, supplements could well be necessary. I did read that they were thinking of adding more vit D to foods in Scotland because of that.
