Vitamin D May Help Prevent Colon Cancer

High levels of vitamin D may be linked to lower risk of colorectal cancer, the fourth most common cancer in the United States.

In a new study, researchers found that participants with the highest levels of vitamin D in their blood had up to a 40 percent reduced risk of colorectal cancer (compared to study members with the lowest vitamin D levels). The study included 1,248 people diagnosed with colorectal cancer, as well as 1,248 people who were free of the disease.

In previous research, scientists discovered that vitamin D may help prevent colon cancer by aiding the body in eliminating a highly toxic substance known as lithocholic acid. Since it's difficult to obtain your recommended daily intake of D solely through dietary sources, many medical experts recommend increasing your vitamin D levels by taking a dietary supplement.
