[ 58 ] On the other hand, the EU Commission defined nutrition labelling for foodstuffs as regards recommended daily allowances (RDA) for vitamin D to 5 μg/day (200 IU) as 100%.
Doses greater than 40 000 IU (1000 μg) per day are generally required before high blood calcium occurs. [12] Normal doses, 800–2000 IU per day, are safe in pregnancy. [5] Cholecalciferol was first described in 1936. [13] It is on the World Health Organization's List of Essential Medicines. [14]
Based on risk assessment, a safe upper intake level of 250 μg (10,000 IU) per day in healthy adults has been suggested by non-government authors. [ 5 ] [ 6 ] Blood levels of 25-hydroxyvitamin D necessary to cause adverse effects in adults are thought to be greater than about 150 ng/mL, leading the Endocrine Society to suggest an upper limit ...

In that study, the compliance calculation could be questionable since only random samples of the returned medications were counted. In a study by De Niet et al., [72] 60 subjects with vitamin D deficiency were randomized to receive 2000 IU vitamin D3 daily or 50 000 IU monthly.
