Vitamins/supplements for arthritis

I'm new to the Versus Arthritis community.I've already posted a couple of messages.Having now had 3 joint replacements for osteo arthritis,I'd describe myself as generally arthritic-ie arthritis in both hands (including some deformity of right forefinger),basal thumb pain and general aches and pains.Fortunately ,it doesn't impinge too much on my life at present.Apart from the usual advice about healthy diet,activity etc I'm just wondering does Versus Arthritis recommend any vitamins /supplements to help reduce/ward off worsening symptoms.I'm 66,retired and in good health otherwise-not on any medication currently!Any views on Turmeric,for example?....Many thanks
