Looking for ways to boost your brain function, improve your memory, reduce inflammation, and help your hair, skin, and nails look better? One of the best ways to tackle all of these complaints is to supplement. Our modern diets often lack certain key vitamins and minerals, such as omega-3.3 Present in a variety of fatty fish, such as salmon, mackerel, herring, and sardines, it’s also present in flax and chia seeds, walnuts, as well as some seed oils such as soybean and canola oil. 1

These dietary sources of omega-3 — which are crucial for brain development during pregnancy, as well as key for better brain function in adults — can be few and far between, or present in doses that are too low to make a difference. Once you’ve decided to supplement, it’s simply a matter of choosing the best option for you. What’s the difference between DHA and EPA? What is marine omega-3 and krill oil? Let’s explore the options here.

What’s the difference between fish oil and krill oil?

Up until recently, most commercially available omega-3 supplements were sourced from fatty fish and were known as marine or fish oil. Krill oil — sourced from those tiny crustaceans found in oceans all over the world — is now also available in supplement form.

Both fish oil and krill oil contain DHA and EPA (Eicosapentaenoic acid and Docosahexaenoic acid), and a lack of these essential fatty acids has been linked to an increase in diseases such as breast cancer, prostate cancer, rheumatoid arthritis, preeclampsia, depression, and schizophrenia.2

However, krill oil’s long chain omega-3’s is better recognised by the body because they are mostly attached to phospholipids resulting in higher cellular incorporation. But what is krill oil?

What makes PhytopureTM Krill Oil special?

Krill oil is known to have a wider range of benefits than fish oil, and PhytopureTM Krill Oil is made with krill harvested from the pristine waters of the Antarctic Ocean. These incredibly pure krill are then processed in a GMP certified, state-of-the-art purpose-built facility at SuperbaKrillTM that utilises patented technology called FlexitechTM to both purify and concentrate the final product.

That final product contains the long-chain fatty acids — DHA and EPA — that we need so badly, as well as phospholipids, astaxanthin and choline, while removing excess salt. It is processed at a low temperature, which further reduces the chance of oxidation when in storage, which is something traditional marine oils can suffer from.

What are the health benefits of krill oil?

Omega-3 is known to be one of the most under-consumed nutrients worldwide3 because most people simply don’t eat enough of those foods to meet their daily requirements. Krill is a great source of omega-3 long chain fatty acids, EPA and DHA, but in addition to this it contains phospholipids, choline and astaxanthin. In fact, there is strong clinical evidence which provides multiple health claims which have been approved by the European Union including:

  • EPA and DHA contribute to the normal function of the heart.
  • Choline contributes to normal lipid metabolism.
  • Choline contributes to normal homocysteine metabolism (the metabolism of amino acids).
  • Choline contributes to the maintenance of normal liver function.
  • Astaxanthin has anti-inflammatory properties whilst also benefiting cardiovascular health.

The benefits of phospholipids found in krill oil

Krill oil is made up of a variety of nutrients namely choline, astaxanthin, and omega-3s (EPA and DHA), bonded to a phospholipid. Human cell membranes are made up of phospholipids, therefore this may facilitate the nutrients in krill oil to pass through the intestinal wall more easily and in doing so, increase the bioavailability of these fatty acids.4


Krill oil for improving cognitive function and memory

Research has indicated that krill oil and its variety of nutrients such as fatty acids, choline, and astaxanthin may improve cognitive function and memory.5-6 Studies have found that supplementing with krill oil may even promote healthy ageing, making it a good candidate for further clinical explorations.7 Strong evidence shows that astaxanthin holds great promise for those wishing to prevent cognitive diseases and maintain general health.8

Krill oil for reducing inflammation throughout the body

Krill oil naturally contains astaxanthin which is a powerful antioxidant that preserves the integrity of the sensitive omega-3 fatty acids and prevents oxidation, eliminating the need to add any preservatives which some marine oils may contain.

Astaxanthin is a promising compound found to be helpful in the prevention or even treatment of different health conditions due to its significant antioxidant, anti-inflammatory, neuroprotective, skin-protective, immunomodulator, and antimicrobial function, as well as its ability to improve lipid metabolism.8 Krill oil is suggested to reduce pain through anti-inflammation mechanisms, due to its high content of astaxanthin.9

Krill oil as a sustainable alternative to fish oil

Fish or marine oil is extracted from fatty fish, and has challenged scientists over the years due to several inherent problems. It tends to oxidise (degrade) during storage, making it less effective over time.10 Additionally, with global fish stocks depleting, it’s becoming harder to meet the growing demand for this most under-consumed mineral.3 These issues, as well as issues related to purity and reflux, led to scientists searching for other options to ensure the transmission of the incredible health benefits of omega-3 supplements.

Phytopure™ Krill Oil contains SuperbaKrillTM who source Antarctic krill — Euphausia Superba— which are harvested in a region of the Antarctic Ocean known as Area 48. SuperbaKrillTM is certified sustainable from the Marine Stewardship Council and use Eco-HarvestingTM technology that reduces the risk of by-catching other species to almost zero, while also ensuring the krill caught remains submerged, thereby avoiding any initial degradation.

The krill oil is then processed using a technology called FlexitechTM which purifies and concentrates the beneficial elements — the phospholipids and choline, for example — while removing the salt elements, which our bodies need less of. The resulting PhytopureTM Krill Oil, is a super concentrated supplement, full of omega-3 fatty acids, phospholipids, choline, and astaxanthin (each of which has a myriad of benefits).

How to choose between marine and krill oil for omega-3 supplementation?

Marine oil and krill oil are great ways to provide your body with the DHA and EPA long-chain fatty acids it needs for optimal brain function. However, if you would like to add in the additional benefits of the phospholipid’s, choline, and astaxanthin, with the additional benefit from the ultra-pure SuperbaKrillTM, then Phytopure™ Krill Oil would be your natural choice. The advances in harvesting method, processing, and natural bioavailability used for Phytoceutics™ has been key in opening up many new possibilities for improving health that have never been attained by an omega-3 supplement.
