Vitamin D is one of the most important nutrients. While people associate with Vitamin D with happiness and sunshine, it actually plays a critical role in sustainable energy. Vitamin D is fat soluble but created with hormones/other nutrients found on the surface of skin. It is then absorbed through fat in the skin and eventually absorbed through the blood stream. As a powerful nutrient, it works by maintaining energy converted from food, supporting your blood pressure regulation (helpful & necessary during stressful times) and promoting your immune system. Vitamin D isn't just for happiness- it is a form of preventative health that requires little other than your presence outside.
