You can't absorb vitamin D through glass, so even having an office window won't help.
I had my Vitamin D levels plummet a few years ago, right before I was diagnosed with Breast Cancer. There's a correlation, but they aren't sure what causes what. I take a daily supplement along with Calcium as I have minor osteoporosis (thanks chemo!) unless I've gotten an hour or so of midday sun.
I believe in supportive medicine like vitamins, in moderation, mainly because I grew up in farm country, where I saw land repeatedly cropped so much that stepping onto a field could be like stepping into a ditch. That much soil (and nutrents got hauled out with the crops) was missing. I rarely saw a farmer fertilize unless it improved yields substantially, which normally it didn't. farmers don't get paid for a nutritionally superior crop.
In the northeast US, where land was also deforested, the effects can be quite bad. If you think back to your earth science, a tree falling and decomposing releases all the nutrients it captured in its lifetime back to the soil. Harvest and haul off all the trees, farm it for 200 or 400 years without adequately fertilizing the land, and the soil gets very depleted.
