I take 2 tablespoons of Udo's 3-6-9 Oil Blend everyday...one in the morning with breakfast, one at night with a protein shake...that seems to help. I also take Universal Nutrition's Animal Flex

I was wary at first, but decided to give it a shot becasue nothing else seemed to work. I am now a believer. I suffer from tendonitis and bursitis in both shoulders, and since I've been taking it, I have had no problems whatsoever.
