Whole Food Vitamin D is an essential nutrient that can be found in a variety of foods, including eggs, dairy products, and fortified breakfast cereals. It helps the body absorb calcium and phosphorus, which are important for strong bones, teeth, and muscles. Additionally, it aids in the body’s immune system, helps regulate mood and sleep, and may even help prevent some chronic diseases. Fortunately, it’s easy to get enough Vitamin D in your diet by eating a variety of whole foods; however, if you’re not getting enough, you may need to take a supplement. Consequently, talk to your doctor to determine the best way to meet your individual Vitamin D needs.
