In findings just published in the journal Anticancer Research, scientists at the University of California (UC) San Diego School of Medicine and Creighton University School of Medicine in Omaha have reported that most people need a much higher intake of vitamin D. And that simple step added to your life could slash your risk of developing serious diseases — including cancer — by about 50 percent.

The new study involved a survey of several thousand volunteers who took supplements containing 1000 to 10,000 IU per day. The researchers ran blood tests to measure the level of 25-vitamin D, which is the form of almost all vitamin D circulating in the bloodstream.

‘We found that daily intakes of vitamin D by adults in the range of 4000 to 8000 IU are needed to maintain blood levels of vitamin D metabolites in the range needed to reduce by about half the risk of several diseases — breast cancer, colon cancer, multiple sclerosis, and type 1 diabetes,’ Dr. Cedric Garland, professor of family and preventive medicine at UC San Diego Moores Cancer Center, said in a statement to media.
