For pigmented skin, it can be up to 45 minutes initially.
Right now, we are experiencing an epidemic in Vitamin D deficiency due to our avoidance of the sun, working indoors, and use of sun blocks/sunscreens that prevent production of Vitamin D in our skin. Low Vitamin D levels have been associated with an increased incidence of many significant diseases. Low D is associated with an increased risk for the following cancers: melanoma, breast cancer, prostate cancer, colon cancer. Low D is also associated with Metabolic Syndrome, chronic inflammation, autoimmune diseases, and increased cardiovascular disease.
