A member asked:

The recommended dosage of vitamin d is kept at 400-600 and many seems to recommend more than 1000iu/day ? why such a different ?

Old ideas die hard: Current clinical data suggest that 2000 iu is probably the best daily dose.

Specializes in Endocrinology

Individual: The 400-600 is for normal people. If your vitamin d is low, you will need more to replace it.

Dr Sparacino and another doctor agreed
