Dr. Cedric Garland, Dr.P.H., F.A.C.E.:
Well, my name is Cedric Garland. I am a professor in the Department of Family and Preventive Medicine, University of California, San Diego School of Medicine. And I work on a lot of subjects, including the role of vitamin D in reducing the risk of chronic diseases.
Well, 25-hydroxy vitamin D is the form of vitamin D that circulates in our blood, and there are about 15 studies now of humans that suggest the people who have high levels of vitamin D in the blood have lower risk of cancer, although there are clinical trials that suggest that just taking oral vitamin D in the typical dose, 400 international units, has no effect on the incidence of cancer.
