Vitamin D: The Sunshine Nutrient and Who Needs It Most

Vitamin D is a fat-soluble vitamin, meaning the body's fat cells absorb and store it. In individuals with a high Body Mass Index (BMI), fat cells "trap" large amounts of Vitamin D, preventing it from entering the bloodstream to reach target organs. Because of this, blood levels of Vitamin D in people with obesity are typically lower, and these individuals often require higher doses of supplements compared to people with a normal weight to achieve healthy blood levels.
