21st Century Hair Skin & Nails is a blend designed to support the appearance and structure of hair, skin, and nails, while also providing a foundational set of vitamins and minerals. It includes a good array of B vitamins, antioxidants like Vitamin C and E, and minerals such as zinc and iodine, all of which contribute to general well-being and cellular health that can impact external appearance.
Beyond the standard vitamins and minerals, this product stands out with ingredients like Biotin, Cysteine Hydrochloride, Soy Protein, and a "Proprietary Herbal Support Blend." Biotin is a popular component for nail strength and hair health, while Cysteine and Soy Protein provide amino acid building blocks. The inclusion of these additional elements aims to offer more targeted support beyond a basic multivitamin.
While the formula is extensive, some ingredient amounts, such as the 25mcg of Biotin, are on the lower end compared to many dedicated hair, skin, and nail formulations that often feature significantly higher doses. The "Proprietary Herbal Support Blend" also means the specific components and their individual quantities within that 310mg are not disclosed, which can make it harder to assess their individual contributions.
