This animal study on guinea pigs shows that fish oil - which is high in omega 3 fatty acids - can help reduce the signs and symptoms of osteo-arthritis.

Given that fish oil has a number of other health benefits too, I think that fish oil is one of those standard supplements we should all take every day, UNLESS you already eat quite a bit of oily fish (at least three portions a week).
