Keratin is also a protein that can be extracted from animals (alpha
keratin) and birds (beta keratin).  Given its natural composition, keratin is highly resistant to water as well as digestive acids. Human digestive tracts cannot break down keratin. Thus, historically its use was limited to topical shampoos and other hair treatment products. Well, at least until now.

Keratin converts dietary collagen into the correct forms of collagen and puts the right type of collagen in the right place. Keratin has a close working relationship in particular with collagen IV and VII. So what does it do?

· By putting the right collagen in the right place, it helps
strengthen and anchor the hair thus reducing shedding.

· By boosting the protein structure of hair and nails, it helps support strengthening and repair.

· It also supports the dermal-epidermal layer reducing the appearance of fine lines and wrinkles.

After persistent multi-decade research and development, a New Zealand company has managed a world-first innovation, making a particular variety of alpha keratin from sheep’s wool, both digestible and functional in the human
body. It is also ethically sourced, traceable, certified vegetarian and made from renewable sources.

Extracted from New Zealand sheep wool, this keratin is 91% homologous to human keratin and contains 18 essential amino acids. It protects our bodies against oxidative stress and promotes glutathione and cysteine production. Glutathione is the master antioxidant and helps protect our bodies from damage to cells caused by pollution, poor diet, stress and free radicals. It is essential for immune function and is vital for building and repairing connective tissue. Cysteine is a non-essential amino acid that helps in the production of glutathione and promotes protein production – thus assisting the body with collagen production.
