The Power of Vitamin D: How to Get Enough and Why It Matters

TLDRVitamin D, known as the sunshine vitamin, is crucial for overall health. It is not a vitamin but a hormone produced by the body when exposed to sunlight. Vitamin D helps with calcium absorption, muscle function, immune system activation, and more. While the sun is the primary source of vitamin D, it can also be obtained from certain foods like fatty fish, eggs, and mushrooms. Supplementation with cod liver oil is another option. Adequate levels of vitamin D are essential for optimal health.
