(NaturalNews) The correlation between serum blood levels of circulating vitamin D and lower risk from many cancer lines has been well documented over the past two decades. Scientists have revealed the mechanism used by this powerful pro-hormone to guide healthy DNA replication and cellular division and to dramatically reduce the incidence of potentially deadly mutations. Publishing in the journal Anticancer Research, researchers at the University of California, San Diego School of Medicine and Creighton University School of Medicine have found that much higher levels of the sunshine vitamin are necessary to prevent or markedly reduce the incidence of breast cancer and other chronic conditions.
The study included nearly 5,000 men and women with an average age of 51 over a period of 5 years. Participants answered dietary questionnaires every six months to ascertain vitamin D levels, vitamin D intake, and health status. Researchers found that the vast majority of adults need to supplement with 4,000 to 8,000 IU per day of vitamin D3 (taken with food or as an oil-based gel cap) to maintain sufficient levels of vitamin D metabolites and to lower disease risk by 50%.
The study demonstrated that the risk of developing a number of chronic diseases including breast cancer, colon cancer, multiple sclerosis, and type 1 diabetes was cut in half by raising the blood saturation level above 50 ng/ml. One of the lead authors Dr. Cedric Garland noted: "I was surprised to find that the intakes required to maintain vitamin D status for disease prevention were so high - much higher than the minimal intake of vitamin D of 400 IU/day that was needed to defeat rickets in the 20th century."
Recommended Daily Allowances for vitamin D were recently bumped up to 600 IU per day for most adults. This study is the first to clearly demonstrate that this small increase is still placing the health of millions of Americans in jeopardy. A report from the National Academy of Sciences Institute of Medicine indicates that 4,000 IU is a safe dosage for everyday use by those nine years of age and older. Many factors including age, race and body weight determine the correct amount of vitamin D needed to raise blood levels, and blood testing is the only reliable method to determine the correct supplemental dose.
Most researchers believe that supplementing to establish a blood saturation level between 40 and 60 ng/ml is needed to provide maximum protection from many cancer lines, diabetes and heart disease. This study found that less than 10% of the population has blood levels that fall within this range and supplementation is essential for optimal health and longevity.
