Hair, Nails, Skin FormulaUltra HNS by Douglas Laboratories supplies high dose biotin, methylfolate, vitamin C, zinc, and Cynatine® HNS, a patented, solubilized keratin for the health of hair, nails, and skin. Cynatine® HNS has demonstrated that it can improve the strength, brightness and appearance of hair, nails and skin as well as reduce hair loss associated with washing.Keratin is a protein found throughout the body and has an important structural role in skin, hair, nails. This intriguing protein also has one of the highest proportions of the amino acid cysteine, a natural reservoir of sulphur and an antioxidant used in many biological reactions. Much of the structural strength of keratin comes from cysteines, which bridge to form a cystine link. The ability to convert natural keratin into a functional form that is bio-available to the body is a recent breakthrough. A patented process now enables the intact keratin molecule to be solubilized, therefore making it both bioactive and bio-available to the body.Cynatine® HNS is a natural bioactive keratin extracted from premium quality pure New Zealand wool using a unique patented process. Cynatine® HNS has demonstrated that it can improve the strength and appearance of hair as well as reduce hair loss associated with washing. It has also been shown to be capable of supporting healthy skin aging as well as improving the strength and luster of nails. A major component of the skin moisture barrier is cysteine-rich keratin. Damage to the keratin in this barrier can also result in increased skin wrinkles. In vitro studies show Cynatine® HNS supports cell proliferation and protein synthesis of human skin keratinocytes. Cell proliferation is used as a marker of cell growth and turnover. A clinical study was performed on Cynatine® HNS which showed that after 90 days, hair loss from washing was reduced by 30%, hair strength was improved by 12%. Additionally,participants reported improvements in bo
