Brief Summary

Vitamin D regulates various physiological functions, including calcium homeostasis, bone health, and potentially reducing cancer risks. Its primary source is Ultraviolet B radiation, but factors like aging, skin type, and modern lifestyles limit sun exposure, leading to widespread deficiency. This study explores using a daily Ultraviolet B Light Emitting Diodes device to improve vitamin D levels while assessing the potential for skin inflammation.
