Vitamin D, better than you thought?

Vitamin D

Vitamin D has long been associated with bone health in women.

A new study in the Journal of the National Cancer Institute found that higher circulating Vitamin D levels appear to be associated with a lower risk of colorectal cancer.

Here are some of the findings in that study:
-25(OH) D or 25-hydroxyvitamin D is the measurement that is made to establish circulating Vitamin D levels
-the level of 25(OH) D that is sufficient for bone health is considered to be around 55 nmol/L
-Vitamin D levels less than 30 nmol/L appear to be associated with an increased risk of colorectal cancer
-Vitamin D levels of 75-87.5 nmol/L seems to be associated with a 19% reduced risk of colorectal cancer
-Vitamin D levels of 87.5-100 nmol/L seems to be associated with a 27% reduced risk
-Vitamin D levels above 100 did not seem to reduce the risk even more.

Of course, more studies are needed to arrive at the proper Vitamin D guidelines but you should discuss these new findings with your health care providers.
