What's the best way to cycle vitamin D? Month - on, month - off? 3 months - on, 3 months - off? 6 months - on, 6 months - off?
Assuming northern country with little sunshine exposure in summer (office work) and almost no sunshine in autumn/winter/spring?
Would it be better to let the levels drop naturally in winter and not to supplement this time while helping to keep them even higher in summer with supplements? Or is it better to supplement in winter and get it naturally in summer (less variance in this case)?

You are presuming that it is good to cycle vitamin D. Why?
I try to keep my levels constant at 45ng/ml. That means I "cycle off" only when I get significant amounts of summer sun.
There is some evidence (based on work by Vieth) that periodic drops in serum vit D are very bad.
