KeraGLO® Hydrolyzed Keratin (Food Grade)

Hydrolyzed Keratin, Food Grade

Animal Health; Hair, Skin & Nails; Women’s Health

Keratin is a structural protein that connects epithelial (skin) cells together and protects them from environmental damage. However, keratin itself is insoluble and is poorly absorbed in the body. Hydrolyzed keratin is keratin protein that has been broken down into smaller molecules and is readily absorbed in the body when consumed orally.

Our KeraGLO® Hydrolyzed Keratin is from poultry feathers and is extensively hydrolyzed to improve absorption. Other forms of hydrolyzed keratin are only partially hydrolyzed and are poorly absorbed and thus may be of limited benefit when used in Beauty from Within products.

NutriScience offers other Beauty from Within ingredients including ElastaGLO®, DNActive® and many others.
