Is krill oil better than fish oil?

I believe that no other vitamin or mineral in the entire nutraceutical business is as good for human health as krill oil. One study showed krill oil may be 48 times more potent than fish oil!
While fish oil can be a good source of omega-3s, there are problems with it. For example, fish oil can spoil quickly due to oxidation, it has low absorption rates and quality control concerns that vary from vendor to vendor. The EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) in krill oil are incorporated into phospholipid molecules which make the omega-3s highly absorbable and bioavailable.
The phospholipid form in krill oil is both fat-soluble and water-soluble, while
the DHA and EPA in fish oil are bonded to triglycerides, which is fat-soluble only. This difference has broad implications for absorption. Additionally, taking krill oil typically does not result in fishy burps and aftertaste related to digestion reflux.
