Osteoarthritis is often associated with osteoporosis (decreased bone density). Taking minerals to support bone health, such as calcium, magnesium, silica, manganese, zinc, boron and copper, may help retain bone strength. Furthermore, antioxidants can help prevent inflammation by inhibiting cellular damage by oxidative stress. Useful antioxidants include grape seed extract, selenium and vitamin C. Lastly osteoarthritis is associated with an acidic body, therefore eating an abundance of alkalising foods and supplementing your diet with green superfoods, such as green barley and alfalfa, is important.
