500,000 IUs of vitamin D in one day is a massive dose but spread over a year it is very little. The paper shows that all participants in this trail had suboptimal vitamin d levels most of the time, except for the treatment arm who once a year were give what I would have assumed was a toxic dose. The most impressive thing is that a dose 2500 times the RDA is safe except for a small increased risk in falling.
For safety, do not attempt to drink a years requirement of water in one day.
