Thats actually a pretty interesting finding! I was surprised it was only 2000IU/d too. I think someone on SI (Maybe Ian?) posted a video a while back about some doc claiming Vitamin D was more of a super Vitamin and how he would increase his intake when sick. I think he took much higher doses too. I take Vitamin D but thought the doc was a bit of a quack but maybe he is really on to something?
