Vit D helps with UC and your levels are probably low if your doctor wants to prescribe it to you. I will assume that yours is like most prescriptions: 50,000 IU of vitamin D2 taken once a week. Some people believe that vitamin D3 that is easily bought OTC is better because it is the natural form of D.
Consult with your doctor of course but taking daily 7,000 IU of D3, or 10 capsules of 5,000 IU taken over the course of the week without a prescription, is about the same as taking 50,000 of prescription D2 once a week. Maybe it would be easier on your stomach to spread it out over a few days. And it should be much cheaper.
