The real RDA for vitamin D

Friday vitamin trivia: What does ‘RDA’ really stand for? The Recommended Daily Allowance (RDA) for vitamin D was set by the IOM at 200-600 IUs a day. But new calculations published in the journal Nutrition calls for closer to 9,000 IUs a day for most people just to obtain optimal blood levels of vitamin D. Even really healthy people generally need about 2,400 IU per day to maintain their levels. So, RDA (according to the IOM) must mean ‘Ridiculously Deficient Amount’.

The best form of D comes from 30 minutes of sun a day!
