The vitamin primarily obtained from sunlight and important for bone health is vitamin D. This fat-soluble vitamin helps facilitate calcium absorption in the gut, which is critical for maintaining strong bones and preventing osteoporosis. Sunlight exposure enables the skin to synthesize vitamin D, making it essential for overall health. In regions with limited sunlight, dietary sources or supplements may be necessary to maintain adequate levels. Ensuring sufficient vitamin D intake plays a key role in supporting skeletal health and overall well-being.
