I have heard in the gym and read once that Krill oil is better. This is what I just read about Krill oil online:
Reduces arthritis and pain inflammation
Lowers bad cholestorol
Krill oil contains vitamin E, vitamin A, vitamin D, canthaxanthin and omega 3s
Acts as an Antioxidant - "The anti-oxidant potency of krill oil is such that when compared to fish oil in terms of ORAC (Oxygen Radical Absorptance Capacity) values, it was found to be 48 times more potent than fish oil"
I saw one cautionary note from someone saying you need to be careful with overdosing vitamin A as this can be stressful on some of the organs.
