Can't tell here: Some people, especially with malabsorption, may need to stay on vitamin d; 50k iu/wk likely is d2 dosing; some may do better with d3 (different dose schedule and amount). Need follow up. Start with a smart internist, then specialists as needed.

Try cholecalciferol: Some people don't respond as well to the ergocalciferol (50k formulation of vitamin d). Cholecalciferol is more potent and seems to stay in the body longer. 2-4k daily is typical for a level as low as yours.
