According to Harvard Medical School, supplements are the safest and easiest way to boost vitamin D levels. Though their recommendation, which appeared in a recent article in the Harvard Heart Letter, is for a mere 800 to 1,000 IU a day, this is a big step for acceptance of the importance of vitamin D supplementation by mainstream medical institutions. http://www.stopagingnow.com/news/news_flashes/7267/Harvard-Gives-Vitamin-D-Supplementation-the-Thumbs-Up ハーバード医科大学、サプリメントがビタミンDレベルを上げるのにもっとも安全かつ簡単な方法であると認める 800-1000IU/dayのサプリメント摂取を勧める

It was found that high levels of vitamin D cut back the risk of developing cardiovascular diseases by 33 percent, type 2 diabetes by 55 percent, and metabolic syndrome by 51 percent. http://www.themedguru.com/20100223/newsfeature/vitamin-d-linked-reduced-heart-disease-diabetes-risk-86132425.html In Tests, Vitamin D Shrinks Breast Cancer Cells Within a few days, half the cancer cells shriveled up and died. Welsh said the vitamin has the same effect as a drug used for breast cancer treatment. http://abcnews.go.com/GMA/OnCall/study-vitamin-kills-cancer-cells/story?id=9904415 intake of an additional 1,000 international units (IU) (or 25 micrograms) of vitamin D daily reduced an individual's colon cancer risk by 50%, and breast and ovarian cancer risks by 30%. The vitamin D hormone, calcitriol, has been found to induce death of cancer cells in vitro and in vivo. The anti-cancer activity of vitamin D is thought to result from its role as a nuclear transcription factor that regulates cell growth, differentiation, apoptosis and a wide range of cellular mechanisms central to the development of cancer. The Canadian Cancer Society was the first to recommend, in 2007, that all of its adult citizens begin taking 1,000 IU per day of vitamin D. Using information from the National Health and Nutrition Examination Survey a group of researchers concluded that having low levels of vitamin D (<17.8 ng/ml) was independently associated with an increase in all-cause mortality in the general population. http://en.wikipedia.org/wiki/Vitamin_D
