I usually take 2000iu's a day of vitamin D. I just got 10,000iu's and it says to take once a week. Do any of you take a large dosage at once instead of daily? I am not sue if the benefits woule be the same or not, but it alleviates taking another supp daily. Had mine tested last year and it was 37 ng/ml and the reference ranges said 32-100 was optimal.
