Keravita Pro is a nutritional supplement made entirely of natural ingredients. Although this supplement focuses on hair and nail health, it can also be used as a general dietary supplement. It contains a variety of essential minerals and nutrients, as well as numerous other supplements for personal health. The blend, or complex if you will, is known as the KeravitaPro proprietary formula. Some people associate the term proprietary with secrecy, but that is not the case here. All active ingredients, both primary and secondary, are listed on the product label and can be researched on independent websites. You might be surprised at how much information is available for each ingredient.
