Collagen Powder is made from the hides of cattle raised in pastures in Germany. It contains 90% protein and provides both type I and type III collagen which are the major components in skin, hair, nails, muscles, tendons, ligaments, bones, gum, teeth, eyes and blood vessels. Our Collagen Powder is 100% pure and contains no fillers, preservatives or additives. Both our Collagen Powder and Granules are Grass-Fed and 100% pure products containing no additives, preservatives or fillers. The Collagen Powder is finer than the Granules and has a mild flavour. Dissolving the Collagen Powder requires some stirring and because of the fine texture of this product, it does well in baking. If you are looking for a tasteless and instantly dissolving collagen then our Collagen Granules is a better product for you.
