Fish oil vs krill oil
Original post in this thread

1. I noticed the omega 3 content in krill oil is significantly lower than fish oil. Around 100 mg epa/dha compared to 650 in the triple strength fish oil, while also being more expensive. Krill oil is supposed to be more bioavailable, but can it be 6.5 times more bioavailable?
2. How stable are both products? I'm looking at the 180ct, can it survive without refrigeration for 6 months? I live in a hot country. Also, will it survive the shipment this time of year? I see temperatures in Phoenix are pretty ridiculous even now haha.
And lastly, are there any other benefits to using krill oil rather than fish oil except for improved bioavailability? I'll gladly pay extra for a more effective product, but would obviously still prefer the cheaper option if the difference is not huge.
Thanks in advance!

This is great study with very informative data for comparing various different sources, thanks for that! I couldn't find much comparing bioavailability of algae oil(which also seem to have high phospholipids) vs krill oil, any suggestions/thoughts? Thanks!
Asking since I'm vegetarian and have seafood(crustaceans) allergy so only vegetarian/vegan sources are suitable for me.

So the omega-3s in algae oil are in different forms. The EPA is partly phospholipid bound (15%), but the DHA is not. The bulk of the omega-3s are in triglyceride form, which is kind of in between the phospholipid forms and ethyl ester forms. It is more bioavailable than ethyl ester forms in purified fish oil. However, it doesn't last in the body as long. The one thing that is nice about the ethyl ester forms are they kind of act as a time-release for the omega-3s. So while you don't reach as high peak plasma levels, they are released over a longer period. So algae oil will reach higher plasma levels than ethyl ester forms from fish oil, but also drop faster. Both have their place.
We are actually working on a high DHA algae-based product right now. It will be in a patented higher bioavailability delivery system, too. So that might be a good one for you once we bring it out.
