High levels of vitamin D have been related to lower levels of breast cancer, report scientists from the University of California San Diego. Expanding on epidemiological studies relating higher cancer levels in individuals with vitamin D deficiency,  the current study published in PLOS One utilized data from two randomized  and one prospective clinical trials. Postmenopausal women with levels of at least 60 ng/ml vitamin D had one fifth the incidence of breast cancer. This level is three times the 2010 recommendation by the National Academy of Medicine. Findings indicated a dose-response relationship — the higher the vitamin D level, the lower the breast cancer level.

Dietary supplements and sunshine provide the body with vitamin D. Different people require different amounts of supplements to reach target levels, so monitoring by a medical professional may be necessary. Keep in mind that very high levels of vitamin D are associated with serious side effects.
