About this study

Vitamins are essential micronutrients required for maintaining normal physiological functions and metabolism in humans. Among them, fat-soluble vitamins (FSV) such as vitamins A, D, E, and K are absorbed in the intestines in the presence of fat. Both deficiencies and excesses of these vitamins can affect health. Current global studies on FSVs in healthy populations are often limited to specific types or regions, and comprehensive data on all four FSVs in the healthy Chinese population are lacking. This study aims to fill this gap by collecting and analyzing FSV levels from healthy adults across multiple regions in China, establishing a reference range for clinical evaluation and early disease intervention.
