Vitamin D Research

Researchers to study effects of high doses of vitamin D.
The New York Times (2/1, Parker-Pope) "Wellness" blog reported that relatively "little is known about what the ideal level of vitamin D really is, whether raising it can improve health, and what potential side effects are caused by high doses." To that end, a "nationwide clinical trial is recruiting 20,000 older adults, including men 60 and older and women 65 and older, to study whether high doses of vitamin D and omega-3 fatty acids from fish-oil supplements will lower risk for heart disease and cancer." Researchers plan to use "one-gram supplements of omega-3 fish oil, about five to 10 times the average daily intake."
