I initially started with 1000 IU of Vitamin D3, Costco brand, and eventually settled on 5000 as I noticed improvements in energy level as I took more.

I am at 43 latitude so I only start taking it in mid-November and start weening myself off it in late March (you never really know if/when spring will happen up here in Toronto :)
