Vitamin D

I thought this was interesting, given that the WAPF recommended dosage of CLO provides "about 500 IU vitamin D for children, 1000 IU vitamin D for adults, 2000 IU vitamin D for pregnant and nursing women" (source: WAPF web site), and I've read that some people are concerned that's too much vitamin D.

Finally, we need to worry about our bones. At least 1.5 million “fragility fractures” occur annually in the United States. These are breaks that result when someone falls from a standing height or less, trips over the cat or lifts something heavy, and they affect men as well as women, Dr. Laura Tosi, an orthopedic surgeon at Children’s National Medical Center in Washington, D.C., said at the New York event.

“A history of a fragility fracture is far more predictive of future fractures than a bone density test,” Dr. Tosi said, adding that a major cause is a shortage of vitamin D, which lets calcium into bones.

“The current standard for vitamin D is not adequate,” she said, and predicted it would soon be raised to perhaps 1,000 International Units a day. Vitamin supplements are crucial, because adequate amounts of vitamin D cannot be absorbed through diet and sunshine alone.

It's not true in general that one cannot make adequate Vit D on sunshine alone. At extreme Northern latitudes, at northern latitudes for those with very dark skin, or for those who cover and/or go out of their way to avoid the sun, vit D is needed in the diet. Traditional diets at far-Northern latitudes that relied heavily on sea mammals and cold water fish (and for the Scandinavians, raw dairy) had PLENTY of Vit D, and the life of a peasant involved plenty of sunshine. Vit D deficiency is by and large a disease of industrial urbanization and the Western Industrial diet.

Relatively few people really need vit D supplementation, and except for young bf infants of vit D deficient mothers, most can get it thru dietary therapies such as cod liver oil.
