What Is Vitamin ?
Vitamin D is a fat-soluble vitamin that exists in two primary forms: Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol). Vitamin D2 is synthesized by yeast and fungi, while Vitamin D3 is produced in the skin through sunlight exposure. Both forms can enhance calcium absorption in the gut and maintain adequate serum calcium and phosphate levels, which are vital for bone formation. Therefore, understanding what Vitamin D is helps in recognizing its critical role in various bodily functions.
Sources of Vitamin
Vitamin D can be obtained through several sources, including sunlight, dietary intake, and supplements.
Sunlight Exposure
Sunlight exposure is the most natural way to obtain Vitamin D. When skin is exposed to UVB rays from the sun, it synthesizes Vitamin D3. The key characteristic of sunlight exposure is its ability to provide high levels of Vitamin D quickly and free of charge. However, utilization hinges on factors such as geographic location, skin pigmentation, and time of year. The unique feature here is the body’s capability to store Vitamin D, leading to sustained levels even in less sunny months. Nonetheless, overexposure can pose risks to skin health, including skin cancer.
