The worldâ€™s leading independent vitamin D advocacy group is reporting on its web site that 6,000 IU of vitamin D daily would be required to get 98 percent of the population up to vitamin D levels it now considers â€œsufficientâ€ â€” a dosage that is 15 times higher than the current median recommendation and is only naturally consistent with getting regular sun exposure.
GrassRootsHealth.org â€” the organization the rounded 41 of the worldâ€™s leading vitamin D researchers into supporting the same vitamin D recommendations â€” is now reporting that data collected from more than 1,000 people show that current vitamin D recommendations wonâ€™t do anything to solve the vitamin D deficiency epidemic.
According to GrassRootsHealth.org, at 1,000 IU daily â€” more than double the current recommendation â€” vitamin D levels in test subjects still range from a low of 15 ng/ml to 85 ng/ml. The group considers 15 ng/ml â€œsevere deficiencyâ€.
â€œ6,000 IU/day would get 98 percent of the group above 40 ng/ml,â€ GrassRootsHealth.org reported on its web site. â€œAt 10,000 IU/day, no one was above 200 ng/ml (a level considered to anticipate toxicity).â€
GrassRootsHealth promotes that it has the worldâ€™s largest ongoing testing project, with more than 1,000 subjects conducting vitamin D tests twice annually. The organization was founded by breast cancer survivor Carole Baggerly, who supports regular vitamin D testing for all and vitamin D production from all sources.
The numbers reported by the organization are concerning, because new vitamin D recommendations from a government panel are anticipated to be out later this month and there is already widespread speculation that the panel making the recommendations will settle for a number around 1,000 IU. The GrassRootsHealth numbers indicate that would not seriously address the problem.
Vitamin D is called â€œThe Sunshine Vitaminâ€ because it is made naturally when skin is exposed to sunlight â€” the only vitamin made naturally without ingesting dietarily. A single tanning session in summer sun or in a sunbed with both UVB and UVA light (more than 90 percent of sunbeds meet this criteria) will make more than 10,000 IU of vitamin D in the skin, according to independent research. No dietary source comes anywhere close to UV-induced vitamin D from sunlight. An 8-ounce glass of vitamin D fortified whole milk contains 100 IU of vitamin D. Fresh salmon from the stream might contain up to 1,000 IU, but that amount is not present in store-bought fatty fish, according to vitamin D expert Dr. Michael Holick.
