SynerG contains Glucosamine, which helps repair and build healthy joint cartilage. It also contains MSM, Bromelain, Boswellia Serrata Extract and Alfalfa, which act collaboratively to reduce pain, inflammation, tenderness and swelling, all common symptoms of osteoarthritis, rheumatoid arthritis and cartilage erosion. What does SynerG target? Osteoarthritis is the degeneration of joint cartilage and the underlying bone, often due to wear and tear. Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. Healthy cartilage in our joints allows the bones to glide over each other with very little friction. Symptoms of osteoarthritis include joint pain, tenderness, stiffness and sometimes local inflammation.
