Vitamin D Supplement: Forms, Benefits, and Recommendations
Vitamin D sits at a curious intersection: it is a nutrient we can make from sunlight, yet deficiency remains common. In the United States, data from the National Health and Nutrition Examination Surveys (NHANES) covering 2001–2014 suggest that 22% of people had moderately low blood levels. That number reflects a mix of modern indoor lifestyles, widespread sunscreen use, and the simple fact that few foods naturally contain much vitamin D. For many, the gap between what we get from sun and diet and what we need leads to the need for supplementation.
