My sister the acupuncture doctor recommended to me Udo's Oil, and it really seems to help when I need the extra anti-inflammatory boost. Don't bother with oils that aren't kept refrigerated with a short shelf life, the active compounds are pretty unstable.

It's also plenty easy to grind your own flax seeds in a mini-chopper or bladed spice grinder and sprinkle them over cereal or salads - same kinds of foods where you'd use the oil.
