Thanks Paxiled, that is interesting feedback
I don't know if the connection is there, but keep in mind until someone got the horrible idea of killing krill, on which the most endangered ocean species depend, so we can have another source of omega 3 oils, people have never consumed them. So who knows what sensitivities might be out there? Fish oil is pretty much as good, and maybe even better for DHA, so you should be fine using fish oil if you feel the krill oil is affecting you adversely. Just make sure you buy a clean source -- one good thing about krill oil is that krill don't live in waters we've polluted as much as other sources of fish oil, but there are companies that are very careful, such as Nordic Naturals. As to your general health, don't know about that either, but krill oil should only help your cholesterol. It's not how much cholesterol you have, it's what kind, and fish and krill oil provide the beneficial kind. You might also not be eating enough sources of HDL, but you can just increase your fish oil or krill oil or hemp seed oil or flax seed oil -- there are other sources of omega 3 oils, though only fish that eat seaweed have a good level of DHA.
