Heaven Sent Purvana Hair Skin Nails Description: Beauty From Within The way we feel about ourselves relates to the appearance of our hair, skin and nails. Accordingly, we tend to give these tissues a great deal of attention when they are on the outside of your body, but this formula makes more sense, supporting healthy growth of these tissues at the only time it can be done-when they are on the inside. Understanding Hair, Skin and Nails The structures of the hair, skin and nail tissue are very similar, requiring almost identical raw materials to grow and remain healthy. Collagen is the most abundant protein in the integumentary system, while elastin allows your skin to stretch like a spring and return to its original shape. These specialized proteins owe their unique properties to the sulfur bonds holding these tissues together. Because sulfur is so vital to their structure, we include a great source of organic sulfur, Methylsulfonylmethane (M.S.M). We also include silicon to help overcome silicon's limited solubility and to better meet the need for silicon in supporting the structural integrity and healthy development of these vital tissues. Purvana also provides Vitamin A (as Palmitate) and all of the B vitamins, and most importantly, very high levels of biotin because it is absolutely essential for the growth of healthy hair, skin and nails.
