Shark cartilage is naturally rich in chondroitin, calcium, and glycosaminoglycans. Chondroitin is a building block of cartilage that supports growth and slows deterioration. Calcium is highly beneficial for people with osteoarthritis and is essential for many physiological activities. Glycosaminoglycans and chondroitin work together to stimulate cartilage repair and prevent cartilage deterioration through structure-modifying effects. This results in less joint space narrowing and healthier synovial joints. Shark cartilage has also been known to relieve pain by reduction of inflammation, prevent macular degeneration and improve skin for people with psoriasis.
