Genetic Variants For Skin Color In African Americans Linked To Vitamin D Deficiency


“One day, physicians may be able to look at an African American’s skin color, and, with the help of other determinants, know if prescribing vitamin D supplements would lower that person’s risk of getting cancers of the prostate, colon, rectum, or breast.” [Source:]


In the United States, African Americans bear a disproportionate share of the cancer burden, having the highest death rate and lowest survival rate of any racial or ethnic group for most cancers.

Significantly, therefore, vitamin D insufficiency is more prevalent among African Americans than other Americans. In North America, most young, healthy African Americans do not achieve optimal vitamin D levels at any time of year. This is primarily due to the fact that pigmentation reduces vitamin D production in the skin.

Many studies have found a protective relationship between sufficient vitamin D status and a lower risk of cancer. Evidence suggests that efforts to improve vitamin D status via supplementation could therefore help reduce cancer incidence and mortality.

To learn how science-based micronutrient approaches developed at the Dr. Rath Research Institute have been shown to block all key mechanisms that make cancer a deadly disease, read the groundbreaking book authored by Dr. Rath and Dr. Aleksandra Niedzwiecki, ‘Victory Over Cancer’.
