About





            

                
A group of eight essential B vitamins that serve as coenzymes in energy metabolism pathways. Cross-sectional studies show an inverse association between B vitamin intake and obesity prevalence, with benefits primarily seen when correcting deficiency states.

            

        

        

        
        
        

            

  
How It Works





            

                
B vitamins serve as essential coenzymes in energy metabolism: thiamine (B1) for pyruvate dehydrogenase, riboflavin (B2) for FAD-dependent enzymes, niacin (B3) for NAD+ in glycolysis and beta-oxidation, pantothenic acid (B5) for CoA formation, and B6 for amino acid transamination. Deficiency in any B vitamin impairs mitochondrial energy production, fat oxidation, and may contribute to fatigue-driven physical inactivity.
