    Kera's provides biotin and essential minerals in their patented TRAACS® forms – which are the only true, scientifically-validated chelated minerals available. These chelated mineral supplements include the TRAACS designation on the label, which stands for The Real Amino Acid Chelate System.


    We believe that true beauty starts from within, and our Kera's Hair, Skin and Nails products are designed to support your beauty goals by providing essential nutrients that your body needs to thrive. Whether you're looking to boost hair growth, encourage skin radiance, or strengthen your nails, Kera's is here to enhance your natural beauty from the inside out.


    Kera's contains a unique, orally-bioavailable form of the keratin – the most common form of protein in your hair, skin and nails – called Cynatine®. Research shows that Cynatine® enhances the strength and resilience of hair and nail tissue. It has also been shown in clinical trials to reduce wrinkles and improve skin moisture and elasticity.
