Keratin Protein that's Solubilized, Not Hydrolyzed: Keratin protein plays a very important structural role in hair, nails and skin. Much of the strength of keratin comes from the amino acid cysteine, which is a large component of keratin. Many keratin ingredients in supplements have little nutritional value because they can't be easily broken down and absorbed and used by the body. One solution to this challenge was to "hydrolyze" the keratin, or chemically chop up the protein into small pieces (often using harsh methods) so they can be absorbed. The problem with this is the keratin loses key aspects of form and function. The Cynatine HNS keratin retains its biological activity because it's solubilized, meaning the keratin is made digestible by gently breaking down sulfur bonds that make it indigestible – while leaving the keratin molecule intact. This is a key reason why Cynatine HNS is the superior keratin choice for improving hair, skin and nail appearance as shown in published research. Biotin From Plants, Not a Lab: Vitamins from food have greater nutritional potency because they're surrounded by nutritional co-factors and co-nutrients that help make absorption easier and support activity in the body. Instead of using a synthetic, isolated source of biotin made in a lab. TrueHNS is made with a plant-based biotin from the sesbania plant. This extract, called RGen-Bio, is 0.5 biotin and the other 99.5 contains supporting co-factors and co-nutrients found in the sesbania plant. A recent research study with RGen-Bio found it was superior to synthetic biotin for many aspects of hair health and appearance (study is awaiting publication). Silica from Organic Bamboo Shoots: Hair strands with higher silica (silicon) content are typically stronger and exhibit greater shine. Silica also helps with collagen formation to help skin look its best, and a greater concentration of silica in nails can make them less brittle and increase luster and appearance. Since many of us fall short on getting adequate silica intake from food alone, TrueHNS includes natural silica from a food source, organic bamboo shoots. This extract is called Orgen-Si, and it is 75 silica. Better yet, this silica is water soluble, which allows for easier digestion and greater hair, skin and nail benefits.TRUSTED USA BASED SUPPLMENT BRAND FOR OVER 20 YEARS – For 22 years, NatureCity has been making premium quality nutritional supplements that put science and nature to work for you. Every NatureCity product is manufactured in the USA by cGMP certified manufacturers using the best of nature from around the globe. No cheap substitutes are used in any products. BAMBOO SILICA HELPS COLLAGEN FORMATION – Bamboo shoots are naturally rich in silica and silicon, which helps improve hair strength and shine and helps make nails less brittle. Silicon also helps with collagen formation to help support better skin appearance. PLANT BASED BIOTIN – Instead of using a synthetic source of biotin made in a lab. TrueHNS is made with a plant-based biotin from the sesbania plant. This biotin is naturally surrounded by nutritional co-factors that support biotin's activity in the body, including helping you produce keratin for better looking hair, nails and skin. KERATIN WITH BENEFITS – Cynatine HNS helps improve hair strength, reduce breakage, and increase shine. It also helps reduce nail breakage and improve nail luster and appearance. For skin, the Cynatine HNS in TrueHNS can increase skin moisture, elasticity and reduce the appearance of wrinkles. Your joints may feel better too. BEAUTIFUL LOOKING HAIR, GLOWING SKIN, AND STRONG NAILS – TrueHNS contains Cynatine HNS, a keratin protein that's solubilized so you can digest it while leaving the keratin intact.
