What is the upper vitamin d limit?
A doctor has provided 1 answer
Upper limit: If you have a very low level before treatment your doctor will prescribe a high dose for a month or two. When you levels are back to normal you should do well with 1000 or 2000 units a day. Unless advised otherwise by your doctor don't "overdose".
