Meta-analysis finds reduced mortality among breast cancer patients with sufficient vitamin d levels.

Anticancer Research published the results of a meta-analysis conducted by a team from the Naval Health Research Center and the University of California, San Diego. The research reveals a protective effect for higher levels of vitamin D against the risk of dying from breast cancer.*


Cedric F. Garland and associates selected five observational studies conducted between 2009 and 2013 that included a total of 4,443 women, among whom there were 471 cases of breast cancer. For women whose serum 25-hydroxyvitamin D levels were among the highest categories, a lower risk of dying from breast cancer was observed. In a pooled analysis of all participants, subjects whose vitamin D levels were classified as high at an average of 30 nanograms per milliliter experienced a 44% reduction in breast cancer mortality risk when compared to those whose levels were low at 17 nanograms per milliliter.

Editor's Note: Dr. Garland stated that, "There is no compelling reason to wait for further studies to incorporate vitamin D supplements into standard care regimens since a safe dose of vitamin D needed to achieve high serum levels above 30 nanograms per milliliter has already been established."
