When I see my doc (an endocrinologist) in 3 weeks, I plan to explain all this and ask if the Vitamin D dose can somehow be split into
weekly doses or doubled up to 50,000 IU
weekly. (The lab order he gave me for use a week or so before this coming appointment includes a Vitamin D blood test, so he'll have the info he needs to make this judgement.)
By the way, isn't the recommended daily dose 400 IU, not 40,000?
