The Differences Between Krill Oil and Fish Oil

January 28, 2016

If you’re intrigued by krill oil and thinking of making the switch from fish oil, let me go a little deeper into some of the differences, and how krill oil is better.

Krill oil is more bioavailable than fish oil. Bioavailability refers to the form nutrients are in, so that the same nutrients are more easily absorbed and used by the body. It also means that digestion is easier, so the characteristic nasty fish burps present with fish oil capsules aren’t as much of a presence with krill oil.

And it’s the key nutrients that are bioavailable: you take fish oil for the Omega-3s, right? DHA (docosahexaenoic acid) is probably one you’ve heard of: it’s an important part of brain development and health. Or you might be familiar with EPA (eicosapentaenoic acid), which supports heart and cardiovascular health. Both are Omega-3s that can have different forms, in fish oil, they’re triglycerides. In krill oil, they’re phospholipids, which are more bioavailable.

“With astaxanthin”; our krill oil’s full name is Deep Ocean Krill Oil with Astaxanthin—it’s a mouth full, but it says a lot about what you need to know!

First, Regeneration USA harvests krill oil sustainably, with the oversight of the World Wildlife Fund Norway. That shouldn’t just give you feelgoods, it’s actually a better way to harvest, with less decomposition.

Second, the krill is harvested from deep oceans where it eats algae and plankton. While krill can be found everywhere, these are pure waters, and the krill also undergoes independent testing to ensure no contaminants. The ice algae it eats is the source of astaxanthin, a powerful antioxidant.

Astaxanthin is such a powerful antioxidant, it helps to preserve the krill oil, no additives necessary. By comparison, many fish oils have to have antioxidants added for preservation’s sake (and a rule of thumb is that additives, even healthy ones like antioxidants, aren’t bioavailable).

With all that, are you ready to switch to krill oil?

Thank you, Emma, for your suggestions. I am involved
and support Greenpeace, Union of Concerned Scientists, Food & Water Watch, and various other environmental organizations either monetarily, by signing petitions, or by calling elected officials. I have divested from companies that harm the planet, including fossil fuels and chemical companies. I drive a Prius C (50-60 mpg in the warmer months isn’t bad). 🙂 If only I could afford a Tesla!

Deep Ocean Krill Oil has their harvesting monitored by the World Wildlife Fund of Norway —that’s about as good as ocean fishing can get.

The other things you mention actually have a much bigger impact. If you want to get involved and make a difference, check out ways to fight climate change, here’s a list of ways to get involved:

To take that list a step further, there’s a lot to write your congressman abut these days. Technology is progressing quickly, including big changes in cars and energy, but there’s a lot of lobbying to stop that from being cheap or allowed at all—so add your voice in support of these technologies.

You can of course also check out the work that World Wildlife Fund does. Fishing near the Scandanavian countries involves a lot of careful ocean management because it’s a critical food source for them, and you can always contribute to the charities that do that work (like by setting up Amazon Smile).

I appreciate and share your concern and encourage you to look into some of these ways to get involved and make a change.

I am very concerned about harvesting krill and the effect it will have on whales, seals, penguins, and squid (in addition to thirteen other species that depend upon krill). “The Antarctic krill population has decreased by as much as 80 percent
since the 1970s. Scientists believe the primary reason may be global
warming, or climate change. The Antarctic Peninsula is a key breeding
ground for krill, and it’s warming faster than any other region on
Earth. Increasing temperatures in the Antarctic also mean less sea ice,
and algae beneath the ice is the primary food source for krill. Humans
harvest Antarctic krill to use as food in fish farms and create krill
oil products. Although krill fishing is limited and monitored, these
activities also play a part in diminishing the Antarctic krill
