This pathway involves a molecule called Nrf2, which plays a crucial role in protecting your body from oxidative stress and DNA damage – two factors that are commonly linked to the development of cancer.3 Overall, evidence continues to accumulate showing that vitamin D is a strong ally to combat cancer.4

Worldwide, cancer is the number 2 cause of death, behind only cardiovascular disease.5 Meanwhile, the global prevalence of vitamin D deficiency (defined as a level of less than 20 ng/ml) and insufficiency (defined as a level of 20 to less than 30 ng/ml) is 40% to 100%.6 Although increasing vitamin D levels may help to reduce cancer deaths, health officials rarely recommend optimising levels for this purpose.
