23. IMPORTANT PSA on relying on sun for D...

 

Windows don't work. UV light doesn't pass through glass, so we can't synthesize D by sitting in front of windows (unless they're made of plastic).

Also, for those of us in the northern hemisphere, the sun is too low in the sky at this time of year for UV light to pass through the ozone layer (unless maybe you're under a hole in the ozone!).

So glass windows, northern exposure means inadequate D without oral supplementation!
