Individuals who have the highest levels of vitamin D3 have a significantly reduced risk of breast and colon cancer, a new study has found.
Researchers at the
The researchers determined that, in
With universal attainment of a serum vitamin D3 level of greater than or equal to 55 ng/ml, the researchers projected that in North America alone at least 60,000 cases of colorectal cancer could be avoided per year and another 85,000 cases of breast cancer if vitamin D3 intake were increased.
In adults, vitamin D3 deficiency, may lead to osteopenia, osteoporosis, muscle weakness, fractures, common cancers, autoimmune diseases, infectious diseases and cardiovascular diseases.
The researchers called for increased vitamin D intake among the general population and recommended that vitamin D2, which is less bioactive, be replaced in favor of vitamin D3, which is more bioavailable and is the same type produced in the body from sunlight.
