Building on a long-standing observation linking vitamin D deficiency to increased risk of colorectal cancer, a new study from UCSD has found countries where people experience lower levels of UVB light often report higher rates of colorectal cancer.
-
Fascinating new research has found a link between opioid addiction and vitamin D deficiency. The research indicates subjects with low vitamin D levels may experience heightened euphoric effects from opioids, making them more susceptible to addiction.
