Researchers from the University of California at San Diego's rule of medicine in Creighton University School of Medicine have discovered that when much higher doses of vitamin D are consumed on a daily basis, the risks associated with developing several major chronic diseases are reduced by approximately 50%.
Dr. Cedric Garland, professor of Family and Preventive Medicine at the University of California, San Diego, and distinguished vitamin D researcher, said "we found the daily intakes of vitamin D by Delta 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, multiples sclerosis, in type I diabetes.
"I was surprised to find that the intakes required to maintain vitamin D status for prevention of disease or so. Much higher than the minimum intake of vitamin D of 400 IU/day that was needed to defeat rickets in the 20th century."
While current federal government daily recommendation of 400 or 600 international units (IU) of vitamin D are not enough to prevent the development of chronic serious illnesses, this study, published in the Journal Anti-Cancer Research has found are not enough to fit the development of serious diseases such as breast cancer.
The researchers reviewed several thousand volunteers taking between 1000 and 10,000 IU per day of vitamin D found that much higher daily intakes of the vitamin are needed to reach blood levels in the healthy range of 40 to 60 ng/mL. And those who take such high doses of vitamin D are less likely to develop serious disease.
Dr. Garland also noted, "Now that the results of this study are in, it will become common for almost every adult to take 4000 international unit a day. This is comfortably under the 10,000 IU per day that the Institute of medicine committee considers as the lower limit of rest, and the benefits are substantial. Now is the time for virtually everyone to take vitamin D to help prevent some major type of cancer, several other illnesses, and fractures."
