Hair, skin, and nail supplements are formulated to support the growth and health of these tissues by providing essential nutrients that may be lacking in the diet. Common ingredients include biotin (vitamin B7), which supports keratin production for stronger hair and nails; collagen, which promotes skin elasticity and hydration; and vitamins C and E, powerful antioxidants that protect skin from environmental damage and aid in collagen synthesis. Other components like zinc, silica, and omega-3 fatty acids are often included to enhance skin radiance, reduce inflammation, and improve nail strength. While these supplements can help improve the appearance of hair, skin, and nails, their effectiveness depends on individual nutritional needs, and results may take time to show. It’s important to pair them with a balanced diet and proper skincare.
