About





            

                
A fat-soluble vitamin with receptors in adipose tissue, skeletal muscle, and the pancreas. Mendelian randomization studies confirm a causal association between low vitamin D levels and higher BMI, and meta-analyses support supplementation for metabolic health in deficient individuals.

            

        

        

        
        
        

            

  
How It Works





            

                
Vitamin D receptors are expressed in adipose tissue, skeletal muscle, and the pancreas. Adequate vitamin D status supports insulin sensitivity, leptin signaling, and calcium-mediated fat oxidation. Deficiency (25(OH)D <20 ng/mL) is independently associated with obesity, insulin resistance, and increased visceral fat — potentially through impaired adipocyte differentiation and increased parathyroid hormone (PTH).
