Vitamin D

Vitamin D is a crucial nutrient that plays a significant role in the body. It helps regulate the absorption of calcium and phosphorus, which are essential for maintaining strong bones and teeth. Vitamin D also supports the immune system, muscle function, and cell growth. The primary source of vitamin D is sunlight, as the skin synthesizes it when exposed to ultraviolet (UV) rays. Additionally, vitamin D can be obtained through certain foods and supplements. Deficiency in vitamin D can lead to health problems, including weakened bones (osteoporosis), increased risk of infections, and muscle weakness. It's important to maintain adequate levels of vitamin D through a combination of sensible sun exposure, a balanced diet, and, if necessary, supplementation under medical guidance.
