I take fish oil mostly for heart, cholesterol, although it is supposed to help with inflammation. I take it with food and never had a "taste" problem.
For joints I took Glucosamine and Chondroitin the "Bio-Flex" formula. When I would forget to take it, I noticed the pain got worse. It doesn't take all the pain away but it does make things more tolerable.
I've been taking Glucosamine (and chondroitin) for years but I can't honestly say it does me any good. I did get some Fish Oil pills last night but I couldn't find the enteric ones. I did some that Says, No Taste (from CVS). I taken one so far... I don't like burping nasty dead rotting stinking fishes! I'll get back to you if the cat starts following me around.
