What is Keratin and Why Supplement?
Many people today try to cover up damaged, dull, dry skin, nails, and hair. But wrinkles, brittle nails, and dry hair go deeper than just external cosmetic issues. These are symptoms of aging connective tissue throughout our body. Connective tissue provides support for hair, nails and skin. As we age, production of structural proteins in hair, skin and nails may become depleted. Fortunately, supplementing with keratin can help restore the loss of these structural proteins in hair, skin and nails.
Keratin is a protein. This protein is one of the largest components of our hair, nails and skin. Because keratin is such a large part of hair, nails and skin, it’s noticeable when depleted or damaged (dry, brittle, frizzy hair; thin, easily broken nails, fine skin wrinkles). Clinical studies show reversals in markers of superficial aging after replenishing the body’s structural proteins. These improvements are observable as more lustrous hair, stronger nails, and more vibrant skin.
However, not just any keratin will do since keratin is not soluble and is poorly absorbed in the body. Hydrolyzed keratin is keratin that has been broken down into smaller molecules that are readily absorbed in the body when consumed orally. KeraGLO features thoroughly hydrolyzed keratin peptides that are better assimilated than other keratin supplements. Many other keratin supplements are either not hydrolyzed at all or are only partially hydrolyzed and are thus poorly absorbed and of limited value.
Keratin for Healthy Hair
Our hair is comprised of about 80% keratin. Keratin can strengthen all 3 layers of our hair (i.e. Cuticle, Cortex and Medulla). Age-related decline in keratin synthesis can result in less stable and flexible hair, leaving hair prone to dryness and breakage with brushing and use of styling products and tools.
Keratins are intermediate filament proteins. In humans about half of all keratins are found only in hair follicles. Keratins are important for mechanical stability and integrity of hair cells and tissues. Some keratins also regulate intracellular signaling pathways, providing protection from stress, repair, healing, and apoptosis. Supplementing with thoroughly-hydrolyzed keratin can help restore lustrous-looking hair.
Keratin for Nail Health
Like human hair, human fingernails are made almost entirely of keratin. As we age, we tend to produce less keratin and fingernails can become brittle, resulting in splitting and fissuring. Nails may also become yellow, gray, dull or opaque. Supplementing with Doctor’s Best Keratin may help restore nail health and appearance.
Keratin for Glowing Skin
Keratin makes skin strong, flexible and maintains a water-retaining skin moisture barrier. As we age, our skin cells tend to produce less keratin. This can result in skin that looks dry and dull. Age-related decline in keratin production makes supplementing important for maintaining healthy skin.
