RE: VIT D at least 800 IU daily: Please read this article from the New England Journal of Medicine. The article does a wonderful job pulling together and summarizing the numerous studies that have been done on the subject. I really think you must read this article, especially pages 273-274. "Above about 35 degrees north latitude (think Atlanta to LA), little or no vitamin D3 can be produced from November to February." Most tissues and cells in the body have a Vit D receptor. Many physical maladies are linked to Vit D deficiency. The studies saw no change in conditions until patients took 800 IU or more daily. I'm taking 5000-6000 IU of D3 a day. When my D3 ran out I tried the D2 the boys were taking and it really was ineffective. They are now on my D3, and I'm back to it. I really think they were seriously under supplemented.
