Hyaluronic acid occurs throughout the body, but especially in nerve, skin and connective tissue. It is a vital ingredient to synovial fluid, which is found in the skin, joints and eyes. Hyaluronic acid lubricates the joints and helps to improve their mobility. Making hyaluronic acid a part of your daily diet may help boost synovial fluid quality in both the skin and joints. It helps to reduce swelling and inflammation. This formula also includes MSM (methylsulfonylmethane) for its additional joint-relieving benefits. MSM has been demonstrated by studies to be able to relieve inflammation and pain that is associated with rheumatoid arthritis and osteoarthritis. It helps to heal tendons and joints.
