Unless you get your levels tested twice a year, which I strongly urge you to do, then please check how much you are taking of Vitamin D on a daily basis. All the sources I know recommend no more than 5,000 iu's a day. It is different if you monitor your levels because you know exactly how much your body needs.
Another thing you need to bear in mind is your vitamin K2 consumption. Vitamin K2 engages in a delicate dance with vitamin D, and you need both in adequate amounts for optimal health.The problems of toxicity with vitamin D are now thought to relate to a deficiency of K2, so addressing this issue is very important.Just one example of how the two work so well together is that vitamin D provides improved bone development by helping you absorb calcium. Vitamin K2 directs the calcium to your skeleton, while preventing it from being deposited where you don't want it. This can happen in your organs, joint spaces and arteries. You will have heard the term "hardening of the arteries" and it is these calcium deposits that form a large part of it.
You can get K2 from some fermented foods, especially Natto (if anyone has tried it please let me know). Natto is the highest source and some cheeses, but unless you test your food you can't be sure you are getting enough. You can either supplement with K2 but my recommendation is to use Dr Mercola's Kinetic starter culture when you make your fermented vegetables. I have managed to source a fantastic supply of this by clicking the link above. Anyone coming on my Gut Health Workshop will see how easy it is to use.
