Vitamin D-3 Inhibits Liver Cancer

A study looked at the effect of vitamin D-3 on the proliferation of a number of types of human and rat liver cancer cells, as well as the rate of growth of liver cancer cell grafts in mice. Vitamin D-3 significantly inhibited the proliferation of three different cell types, while two were more resistant to the inhibitory effects of the vitamin. Thus, the treatment of tumor bearing mice with different doses of vitamin D-3 significantly retarded tumor growth without the development of hypercalcemia (excess of calcium in the blood).
