“This study supports the hypothesis that higher serum 25(OH)D levels reduce the risk of breast cancer”… Department of Family and Preventive Medicine, University of California San Diego

“Colorectal cancer mortality was inversely related to serum 25(OH)D level, with levels 80 nmol/L or higher associated with a 72% risk reduction”… Division of Cancer Epidemiology and Genetics, National Cancer Institute

“…we conclude that higher plasma levels of 25(OH)D are associated with a lower risk of colorectal cancer in older women, particularly for cancers at the distal colon and rectum” … Channing Laboratory, Department of Medicine, Brigham and Women’s Hospital and Harvard Medical School

“Improving calcium and vitamin D nutritional status substantially reduces all-cancer risk in postmenopausal women”… Osteoporosis Research Center, Creighton University, Omaha, NE

“Intake of 2000 IU/day of Vitamin D3, and, when possible, very moderate exposure to sunlight, could raise serum 25(OH)D to 52 ng/ml, a level associated with reduction by 50% in incidence of breast cancer, according to observational studies”… University of California, San Diego, Department of Family and Preventive Medicine… Harvard School of Public Health

“The evidence to date suggests that daily intake of 1000-2000 IU/day of vitamin D(3) could reduce the incidence of colorectal with minimal risk”… University of California San Diego, Department of Family and Preventive Medicine, School of Medicine

“In two U.S. cohorts, higher intakes of vitamin D were associated with lower risks for pancreatic cancer. Our results point to a potential role for vitamin D in the pathogenesis and prevention of pancreatic cancer”… Department of Preventive Medicine, Feinberg School of Medicine, Northwestern University … Harvard School of Public Health, Harvard Medical School, Dana-Farber Cancer Institute

“We conclude that low levels of 25-VD associated with an increased risk for subsequent earlier exposure and more aggressive development of prostate cancer, especially before the andropause”… University of Tampere, Medical School, Finland

“Studies over the past several decades have tended to support that higher levels of vitamin D may decrease risk of colorectal cancer”… Channing Laboratory, Department of Medicine, Harvard Medical School and Brigham and Women’s Hospital

“It is projected that raising the minimum year-around serum 25(OH)D level to 40 to 60 ng/mL (100-150 nmol/L) would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, and three fourths of deaths from these diseases in the United States and Canada, based on observational studies combined with a randomized trial. Such intakes also are expected to reduce case-fatality rates of patients who have breast, colorectal, or prostate cancer by half”… Department of Family and Preventive Medicine, University of California San Diego

“From multivariable models, an increment of 25 nmol/L in predicted 25(OH)D level was associated with a 17% reduction in total cancer incidence (multivariable relative risk [RR] = 0.83, 95% confidence interval [CI] = 0.74 to 0.92), a 29% reduction in total cancer mortality (RR = 0.71, 95% CI = 0.60 to 0.83), and a 45% reduction in digestive-system cancer mortality (RR = 0.55, 95% CI = 0.41 to 0.74)”… Channing Laboratory, Department of Medicine, Harvard Medical School and Brigham and Women’s Hospital

“In this prospective study, plasma 25(OH)D levels and common variation among several vitamin D–related genes were associated with lethal prostate cancer risk, suggesting that vitamin D is relevant for lethal prostate cancer”….
