Vitamin D is a crucial nutrient that helps the body absorb calcium, promoting healthy bones and teeth. It can be obtained through sunlight exposure, certain foods like fatty fish and fortified dairy products, or supplements. Deficiency in Vitamin D can lead to health issues such as osteoporosis and weakened immune function. In addition to bone health, Vitamin D plays a role in regulating mood and may help reduce the risk of chronic diseases. It's important to maintain adequate levels of this vitamin, especially in regions with limited sunlight. Regular testing can help ensure you are within the optimal range.
