1. Introduction Vitamin D is an essential fat-soluble steroidal hormone that can either be obtained from dietary sources, such as mushrooms or fish, or synthesized within the epidermal skin layers upon exposure to UVB rays [1,2]. Epidemiological research indicates that a significant proportion of the world’s population lacks adequate levels of vitamin D3, the active form of vitamin D [3,4]. Vitamin D deficiency affects over a billion individuals worldwide, making it increasingly prevalent [5,6,7].
