About





            

                
Biotin (vitamin B7) is a water-soluble B-vitamin serving as a cofactor for carboxylase enzymes essential for fatty acid synthesis and amino acid metabolism. Biotin deficiency clearly causes dermatitis, brittle nails, and hair loss. However, systematic reviews have found limited evidence that supplementation above adequate intake levels improves skin health in non-deficient individuals.

            

        

        

        
        
        

            

  
How It Works





            

                
Water-soluble B-vitamin (B7) serving as a cofactor for carboxylase enzymes essential for fatty acid synthesis and amino acid metabolism; supports keratin infrastructure in skin, hair, and nails through lipid metabolism in the stratum corneum.
