Put some in your head please

Recommendation for vitamin D intake was miscalculated, is far too low, experts say
Researchers are challenging the intake of vitamin D recommended by the National Academy of Sciences Institute of Medicine saying their Recommended Dietary Allowance for vitamin D underestimates the need by a factor of ten.
...
The recommended intake of vitamin D specified by the IOM is 600 IU/day through age 70 years, and 800 IU/day for older ages. "Calculations by us and other researchers have shown that these doses are only about one-tenth those needed to cut incidence of diseases related to vitamin D deficiency," Garland explained.
Robert Heaney, M.D., of Creighton University wrote: "We call for the NAS-IOM and all public health authorities concerned with transmitting accurate nutritional information to the public to designate, as the RDA, a value of approximately 7,000 IU/day from all sources."
