Glucosamine and Chondroitin Sulfate are compounds that promote joint cartilage repair and alleviate the symptoms of arthritis. You can go for Marine lipids such as cod liver oil or salmon oil since they contain Omega-3 fatty acids. They possess anti-inflammatory properties and provide substantial amounts of vitamin D (required for bone growth and vitamin A). They also decrease the pain and swelling significantly. You must add vitamin E supplements when taking fish oils.
Studies show that consumption of Gamma Linolenic Acid or GLA provides as much as a 30% improvement in treating arthritic symptoms. You can take supplements in the form of Evening Primrose Oil, about 2gm a day in a divided dose. Grapeseed extract, also known as pcynogenol, contains proanthocyanidins, which give relief from inflammation. Bromelain and proteolytic enzymes help counteract the inflammation and also reduce the swelling. Boron is yet another mineral highly important in treating osteo-arthritis. Supplementing with boron has proved to be effective in producing a remission of arthritic symptoms.
Take a lot of antioxidants such as vitamin E, C and beta carotene. These help prevent the breakdown of cartilage and are vital for the synthesis of collagen. Vitamin C along with bioflavonoids helps strengthen capillary wall. Vitamin E along with selenium controls inflammation of the joints by inhibiting prostaglandin production.
