Does taking daily vitd supp is better than weekly??(same quantity in total) cz told me that daily is better cz more vit gets in my body! is it true?

Not Necessarily: We usually prescribe high doses of Vit D. for individuals who are Vitamin D deficient. The doses could be as high as 50,000IU weekly or 2 times a week depending on how low their levels are. Normal daily doses depending on where you live should be about 500 to 1000 iu daily.

Either is fine: Total dose is what matters. Ok to take weekly if more convenient.
