The vitamin D Council has just published new data that confirms the need for a high level RDA of Vitamin D.
"The vitamin D dosages only accounted for supplements, and excluded vitamin D intake from the sun and food. The researchers estimated that the intake from the sun and food amount to be around 3000 IU daily.
“Since an RDA, by definition, relates to intake from all sources, it is clear that total intake required to achieve 20 ng/mL in 97.5% of the cohort must be close to 7000 IU per day, not substantially different from that calculated by Veugelers and Ekwaru.”
