"Formerly Bone-Sil"This superior plant-based silica plays a key role in bone formation and the production of collagen, the protein used to form ligaments and tendons. A proprietary extraction process produces silica with enhanced absorption.Healthy bones need silica, but they need a form that is best utilized by the body. Silica-20 is the right choice. It provides silica gently extracted from horsetail (Equisetum arvense) blended with trace minerals from the sea and healthy marine lipids to enhance absorption.For calcium utilization, Silica-20 can make a big difference it boosts calcium absorption into the bone by an average of 50% Plus, it supports healthy bone density in two ways: it helps your body build the collagen framework for healthy bones, and it helps calcium collect on that framework. The result is strength from within for your bones and teeth. Because of its positive benefits for collagen, Silica-20 also supports healthy hair, skin, and nails.Bone Mineralization: boosts bone absorption of calcium up to 50%Supports healthy bone structure and densityBoosts collagen production up to 50% for healthy skin, hair and nailsDietary ConsiderationsWheat FreeDairy/ Milk FreeGluten FreeSoy FreeYeast FreeSugar FreePreservative FreeSalt FreeCorn FreeFree of Artificial Colors/FlavorsServing Size:2 TabletServings Per Container:30 Amount Per ServingVitamin D3 (cholecalciferol) 200IU Horsetail (Equisetum arvense) Aerial Extract standardized to 20 mg of Silica, with naturally occurring flavonoids 800mg Other ingredientstricalcium phosphate, magnesium hydroxide, coating (hydroxypropyl methylcellulose, titanium dioxide, stearic acid, microcrystalline cellulose, chlorophyll), silica, fish (dogfish) oil, vegetable source magnesium stearate, trace minerals (from the sea), maltodextrin, ethylcellulose Suggested Use1-2 tablets daily, or as recommended by your healthcare practitioner.No sugar, salt, yeast, wheat, gluten, corn, soy, dairy products, artificial coloring, artificial flavoring, or artificial preservatives.
