Fish oil is rich in Omega-3 Fatty Acids. However, it also contains saturated fat. I have taken the stuff since December 07 when I went into Atril Fibrillation. That's no fun for someone who is 29. Not fun for anyone, but especially not fun for a 29-year-old. Luckily mine appears to have been caused by stress, but I am on the path now. Weight Watchers off and on, now I am on for good. 5 weeks in and 16 pounds down. It works.
