On reading this chapter on calcium, it looks like oral vitamin D toxicity begins in the liver, although serious effects take considerable time to develop.

There's a table that shows that someone was taking 300,000 IU for six years!

Even this ultraconservative assessment of vitamin D requirements (AI estimate at 200 IU for adults) does not show toxic effects at 20,000 IU. The determination of vitamin D need is solely on the basis of not having rickets.
