Eggshell Membrane, that protective barrier that remains in the shells of raw broken eggs, has been shown to significantly reduce joint pain and improve joint function. According to Dr. Karen Becker, eggshell membrane contains a number of natural substances for today’s pets, including:
• Collagen - A fibrous protein that supports cartilage and connective tissue strength and elasticity.
• Elastin - A protein that supports skin, cardiovascular, cartilage, and spinal health. Elastin gives tissue its elastic tension and ability to resume its shape after stretching.
• Desmosine and isodesmosine - Two little-known amino acids responsible for elastin’s elastic or “rubbery” properties.
• Glycosaminoglycans (GAGs) - Includes glucosamine, chondroitin, and hyaluronic acid - vital polysaccharides that are structural components of connective tissue, interstitial fluids and skeletal structure.
• Transforming growth factor-b - A protein that plays a crucial role in cellular differentiation and immune function.”
