For Hypertriglyceridemia "I started taking this 9/19. By October, I thought I had pancreatitis. Stomach acid high, no ulcer. Horrible stomach pain continued till they put me on ulcer meds, but no ulcer. Bad back pain, like my back was breaking by May. MRI, no new issues and PT not helping. Looked at side effects after getting hives and a rash. I think my body has had enough of this. Now, I have a liver cyst. Read side effects before taking."

"I took the enteric-coated, triple-strength Fish Oil, 1400 mg, one a day for about one week, and I developed stomach and abdominal pain and itching. I stopped taking it, and after a week, the pain and itching were gone. It is now about a month since I stopped taking Fish Oil, and the pain and itching did not come back."

For Dietary Supplementation "Read all the reviews, but decided to try these out anyway. Boy, oh boy, big mistake. Within the hour, I was having severe stomach pains and diarrhea, it was awful. Do not take these pills, try something else."
