Green mussel powder contains protein, chondroitin and glucosamine sulfate, complex carbohydrates and a unique combination of fatty acids not found in any other form of aquatic or plant life. The concentration of Omega-3 is very high, and is said to be over 200 times more potent than the Omega-3 found in salmon oil. The combination of arachidonic acid (a type of Omega-3 fatty acid) and glucosamine plays an important role in reducing inflammation and pain, and improves mobility in dogs affected by arthritis. Green mussel extract powder added to food has been shown to significantly improve inflammation, swelling and mobility in just six weeks of treatment. It is an effective supplement for the management of osteoarthritis and rheumatoid arthritis. It has also proved effective in the management of degenerative joint diseases.
