Make sure not to take more than that without consulting with ahealth professional. Bottom line:Vitamin D intake is recommended at 400–800 IU/day, or 10–20 micrograms. However, some studies suggest that a higher dailyintake of 1000–4000 IU (25–100 micrograms) is needed to maintain optimal bloodlevels.
