60 x 500mg softgels (30 servings)



Harvested sustainably in the Antarctic ocean, the benefits of Euphausia Superba (Krill) Oil come from the omega 3 fatty acids they contain, specifically, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), as well as the antioxidant astaxanthin which gives the krill oil its distinctive red color, and finally the presence of phospholipids are believed to help the body absorb the DHA and EPA better when compared to fish oil (ref). For comparison, instead of the omega 3 fatty acids being bonded to phospholipids like in krill oil, the omega 3 fatty acids in fish oil are bonded to triglycerides. No matter the source of omega 3’s that you get, there is extensive research into the benefits they provide for cognitive function, heart health, and joint health.


1-3 grams per day is the recommended serving. DO NOT take if you have an allergy to fish or shellfish.


Krill oil was shown to have a very high toxicity in rats with no adverse side effects with large intake (ref); suggests that the toxicity level is very high in humans. DO NOT take if you have an allergy to fish or shellfish.

Full Analysis

Krill Oil is a specific type of fish oil that offers greater absorption of DHA and EPA for cognitive function and reduced inflammation. It is also a reliable source of astaxanthin, which is another brain boosting molecule.

  • Full of omega-3 fatty acids DHA and EPA (reference)
  • Helps reduce inflammation and act as neuroprotective (ref)
  • Reduces symptoms of anxiety and depression (ref)
  • Helps improve memory and brain blood flow (ref)

Krill Oil Benefits

Fish and krill oil are both healthy sources of omega-3 fatty acids. These fatty acids are required for proper cognitive and physical performance, but most people in the world do not have adequate doses of these nutrients. Instead, they consume a diet high in omega-6 fatty acids, which can lead to inflammation, obesity, and a variety of other diseases. By taking a fish oil supplement, you can counteract some of these negative effects.

The main omega-3 fatty acids that humans need are DHA and EPA. These should not be confused with other (non-essential) omega-3s, such as ALA, which is often touted as beneficial for your brain when it isn’t. The reason EPA and DHA are so important is because of the composition of our human brains and the historical reliance we have had on fish.

The benefits of krill oil specifically have to do with absorption. The krill oil DHA and EPA is more bioavailable (easier to absorb), which means a dose of the oil is more potent than many other forms. If you buy krill oil, you’ll also have the advantage of astaxanthin, which is a special molecule in krill. It is cognitive enhancing with many long-term benefits.

Krill Oil Studies and Side Effects

Most of the research on krill oil thus far is on the subject of astaxanthin and how much more effective this specific oil is for omega-3 fatty acid absorption. Most people who are using fish oil supplements do not realize the difference between that and krill oil. However, krill oil studies are quite conclusive on the benefits of using this supplement for cognitive enhancing purposes.

The evidence of omega-3 (specifically DHA / EPA) is quite substantial as well. Many studies show how effective it is for improving markers of inflammation, preventing illness (through a strengthened immune system), and helping to protect neurological connections. Given that 60% of the brain is made up of fat, it makes sense.

Luckily, there are not many side effects of krill oil or fish oil. There are anecdotal reports of krill oil causing gout, but nothing substantiated by science.

Buy Krill Oil

You can purchase krill oil in local stores and many places online. Pure Nootropics does have a reputation for high quality products, however. The reputation of the company you buy from matters so keep this in mind.
