Vitamin d deficiency: why one large dose per week instead of easier to remember smaller doses every day?

No Reason. In vitamin d deficiency many physicians prefer a daily dose of 5, 000 iu of vitamin d3 rather than 50, 000 iu once weekly due to poor absorption of a single dose of 50, 000 iu. Once 25 hydroxy vitamin d levels reach 60 - 80, the daily dose is usually cut in half and the patient followed to ensure the new dose is able to maintain therapeutic vitamin d levels.
Vitamin D. You can take vitamin d 1000 units daily which is the recommended normal dose. If your vitamin d lievel is low despite taking that dose, you may double or triple it and have your level checked back in 3-6 months to make sure that there is no overdosage.
