Yes, vitamin D is well-known to be harmful in excess [0] and to be fat-soluble, meaning that it can build up gradually over time. You might not hear of such conditions very often, though, since getting excess vitamin D usually takes effort.

- teilo 6y agoIt takes a LOT of effort. Like in excess of 50K UI a day for months. And then it needs co-factors to do harm, like excess calcium intake along with a K2-MK7 deficiency and/or a potassium deficiency (both of which are, unfortunately, very common). All in all, it's a very complex system that interacts with the body's buffering mechanisms.
