Formulation Notes

Direct keratin protein Body Kitchen uses a clinically studied and patented form of direct keratin that is readily bioavailable and easily absorbable. To make this process highly-effective, we've included black pepper extract to improve absorption rate of all nutrients in the formula by 30% Full-cycle keratin We've added 3,000 mcg of biotin! This combination allows a constant cycle of keratin production - while keratin is ready for quick absorption, biotin engages in a break-down process that stimulates more keratin production in later stages. Backed by minerals such as zinc and copper, keratin enrich is an excellent choice for improving nail strength as well.
