Dear Mull, I have been on fish oil 4grams/day for my cholesterol, triglycerides etc, the only fish oil that seems to work is from amerisciences, most over the counter suppliments here in the u.s. are worthless. I come from a medical family and also my brother in law is a naturopathic physician. I have CD since I was a kid(now 38)and have had many many problems- surgeries -problems from surgeries -etc etc etc, I wish everyone the best of luck, and prayers. My own doc's (M.D.'s)along with my family all admit that there needs to be standards with otc suppliments. Only ones from europe or very few from the U.S. actually meet standards, -P.S. "amerisciences" break down and absorb very well, which is important for those of us with CD or other abdominal problems- I have only been taking their fish oil for 6 months now and (are you ready for this) - my cholesterol was cut in half, yes half! and my bad cholesterol down by 40%, good cholesterol up by 15%, and triglycerides down about 40%. Knock on wood, it seems to help my CD and skin also. There are many brands, but would look toward something that has standards from europe or similiar to "amerisciences" Again best of luck in finding what works for you and again bless us all- Mike
