Scientists Confirm Institute of Medicine Recommendation for Vitamin D Intake Was Miscalculated and Is Far Too Low
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.I'm currently taking 2500 IU of Vitamin D3 (5 days/week), to ward off the flu; I haven't gotten a cold or the flu in a year and one month. Parents of babies should know that Vitamin D administered in the first year of life reduces the risk of Type I Diabetes by 90% according to a Finnish study.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.”
Intake of vitamin D and risk of type 1 diabetes: a birth-cohort study.
Vitamin D supplementation was associated with a decreased frequency of type 1 diabetes when adjusted for neonatal, anthropometric, and social characteristics (rate ratio [RR] for regular vs no supplementation 0.12, 95% CI 0.03-0.51, and irregular vs no supplementation 0.16, 0.04-0.74. Children who regularly took the recommended dose of vitamin D (2000 IU daily) had a RR of 0.22 (0.05-0.89) compared with those who regularly received less than the recommended amount.
