Question: Which diseases are you most confident about vitamin D being able to prevent
Grandmothers around the world have been using cod-liver oil for a long time
TB sanitariums hundred years ago knew to get the patients out in the sun
Dr. Holick: Vitamin D toxicity is one of the rarest medical conditions in the world
Level by the IoM (when Dr. Holick served) in 1997 was only 10 ng – which was 2X too low, still might be off by 2X ( so might be 60 ng next time around?)
Dr. Holick: 1950 Naval personnel who worked indoors more likely to die of cancer than those who worked outdoors
Dr. Holick: Vitamin D2 was grandfathered by the FDA, and was cheap to make
Dr. Manson IoM found there was enough data to support levels for bone health
Dr. Manson: The levels were established only for healthy people
Obeservation by Henry Lahore: Seems that IoM established that 600 IU was enough, THEN determined that 20 ng would result.
Dr. Manson’s vitamin D RCT: Vitamin D and Omega 3 trial = VITAL 20,000 2,000 IU added, anticipate 35-40 ng www.vitalstudy.org
Dr. Manson noted Difficult to get even 600 IU vitamin D via food

Observation by Henry Lahore: Data cutoff for IOM was about mid 2008 – and there has been a lot learned since then – over 6,000 studies published as of Feb 2012
US level 20ng will probably be raised. Much better than the UK level which is 10 ng as of Feb 2012

Vitamin D has long been recognized as critical for preventing rickets in the bones of young children. Research over the past decade or so has also established that it is essential for warding off osteoporosis in older adults.
There is a mystery as to why so many different cells in the body have vitamin D receptors. How does this vital nutrient affect arthritis, blood pressure, diabetes, cognitive function, psoriasis and muscle weakness? Learn how much vitamin D you need, and whether vitamin D2 or D3 is better. How can we avoid toxicity?
