A new study of 3,299 persons has shown that those with higher levels of vitamin D cut their risk of dying from cancer in half. Another recent study shows that ample intake of vitamin D, about 2,000 IU per day, can cut breast cancer incidence by half. Still more research found that inadequate Vitamin D is "associated with high incidence rates of colorectal cancer" and specifically urges that "prompt public health action is needed to increase intake of Vitamin D-3 to 1000 IU/day."
Vitamin D's anticancer properties are so evident, and so important, that the Canadian Cancer Society now recommends supplementation with 1,000 IU of Vitamin D per day for all adults in winter, and year-round for persons at risk.
