Delivers a superior dose of Omega-3s for brain, heart, and joint health*

Experience the gift of being able to move better, think better, and feel better. Omega-3s are present in all longevity-driven diets. However, we can rarely get enough in our standard foods. That’s why fueling the brain and body with key fatty acids primes it for optimal focus, memory, and cognitive function with each passing year.*


A scientifically-proven superior option to fish oil

Don’t settle for the inferior choice. Your brain deserves only the best. Krill oil contains both DHA and EPA omega-3 fatty acids and the antioxidant astaxanthin. This makes it the superior option compared to fish oil supplements. These antioxidants support the brain directly and deliver premium support for healthy aging.*

Synergistic Ingredients

Docosahexaenoic Acid (DHA)

Cold-pressed, pure DHA

Eicosapentaenoic Acid

High potency, cold pressed.

Esterified Astaxanthin

Naturally found in krill


Gives krill oil significantly greater bio-absorption than fish oil.

Docosahexaenoic Acid (DHA)

Omega-3 fatty acid docosahexaenoic acid (DHA) is proven to support healthy joints, support cognitive function, and promote muscle growth. Natural Stacks™ Krill Oil uses only sustainably harvested krill from the pristine Antarctic ocean. It’s immediately cold-pressed while still on board the vessel to preserve the biological benefits of the krill.

Eicosapentaenoic Acid

Omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) have been proven to support support healthy joints, support cognitive function, and promote muscle growth.

Esterified Astaxanthin

Naturally found in krill, astaxanthin is a powerful ingredient. The only two main sources of this fat-soluble ingredient are the microalgae that produce it (haematococcus pluvialis) and the sea creatures that consume the algae. It’s what gives salmon their pink color and is the driving force behind their incredible endurance.


EPA and DHA omega-3 fatty acids in krill are bonded to cell-building phospholipids. This gives krill oil significantly greater bio-absorption than fish oil.

Great Product

No better Krill Oil on the market - hands down the best quality out there and highly effective!

Carl P.


Awesome quality

I'm a big believer in the health benefits of taking high quality Krill Oil. I know I can trust what I'm getting in your supplements and you make ordering easy. I have never had any issues and always get prompt service. I love the flexibility of your auto-ship program!

Rick C.



I like taking the krill because the body absorbs it a lot easier than your regular fish oil and your body makes better use of it . I’d much rather take one pill than a whole bunch of fish pills to get the same effect.

Jesse T.


Repeat purchaser of Krill Oil

In a time where our oceans health is starting to deteriorate- Natural Stacks is the only company I trust to provide a fish oil that not only does what it claims to do, but contains what it advertises to contain. It can be hard to track the results of your supplements, but as someone who sometimes struggles with their mental health, I do find that this krill oil leaves me feeling better and stronger mentally.
