Vitamin D is a star nutrient these days, as research links it to numerous health benefits. Studies suggest vitamin D may go beyond its well-established role in bone health and reduce the risk of cancer, heart disease, stroke, diabetes, autoimmune diseases, and more.
What makes vitamin D unique is that it is a vitamin and also a hormone your body can make from the sun. Despite the ability to get vitamin D from food and the sun, an estimated 40%-75% of people are deficient.
Why? Vitamin D is not abundant in our food choices and the sun is not a reliable source for everyone.
