Sunshine the most important natural source of vitamin D

A recent paper published in Clinical Nutrition on Vitamin-D, showed that “UVB-induced dermal synthesis can meet 80–100% of vitamin D requirements, making sunshine the most important natural source of vitamin D for many.”

The study concluded that UVB exposure was strongly associated with vitamin D levels. The increase was most obvious among Whites, at 35%, compared to 20% and 15% for Black and Asian participants, respectively.

Vitamin D is produced in the skin following exposure to ultraviolet B (UVB); however, the amount of vitamin D produced through this process depends on the individual’s skin colour and age, as well as the intensity of incident solar radiation.
