What this means
This study showed that vitamin D levels in the blood correlated with a lower risk of developing Colon Cancer and Colorectal cancer. While it doesn’t say whether vitamin D is causing a benefit, it does show that those who have lots of vitamin D tend to have a lower risk.
Why This Matters
Similar to the Colon Cancer data, this research further demonstrates that those who have high vitamin D levels in their blood have a significantly lower risk of developing cancer.
Clinical trials have not shown benefits to vitamin D supplements.
Supplements may not work
While having high blood levels of Vitamin D shows clear benefits, taking vitamin D supplements may not show benefits for cancer risk as shown by the study below.
Blood levels of Vitamin D have consistently shown a correlation with a lower risk of developing cancer. However, clinical trials show that taking supplements may not reduce your risk of developing cancer. This suggests that the benefits of vitamin D cannot be obtained by taking supplements. Rather, vitamin D levels may be an indicator of a healthy lifestyle. As always, diet and exercise are a safe bet.
