A yet another study about vitamin D was published today in PLOS One showing that women with higher blood levels of vitamin D have a significantly lower risk for breast cancer.
The study included more than 5000 women with a wide range of vitamin D blood levels. The results showed that women with a vitamin D level in blood of >60 ng/ml had an 80 percent lower risk for breast cancer than those with levels of 20 ng/ml or less. This is quite a significant result showing that blood levels of vitamin D may need to be even higher than what is currently recommended for bone health.
