In case you live in a northern climate and want to catch some rays through a window. Glass filters >90% of the rays that cause vitamin D production.

- zamfi 6y agoNot only that, but a large fraction of the English-speaking northern hemisphere does not receive enough sunlight in winter months for the skin to produce Vitamin D.

I take 10k IU's of vitamin D per day. Absent that, my natural (un-supplemented) vitamin D tests come back with a level about 20+ (30-100 being the desired range).
- HelenePhisher 6y agoWhat are your levels when you use supplements?
- wyldfire 6y agoThat's interesting, I was just wondering whether we get any benefit from ambient sunlight indoors. So you're saying 'yes' (a limited / very modest benefit). But how much sunlight do you need in order to saturate your vitamin D production? If I'm indoors in a room with a lot of windows all day, is that good enough?
