If you’ve ever been looking to buy krill oil, you may have heard of Neptune Krill Oil.

It’s sold by many different nutritional supplement companies and it’s one of the most popular types of krill oils available in North America.

However, with so many different types of oil to choose from, you may be wondering if Neptune Krill Oil ingredients are the same or better than the competition.

The Story Behind Neptune Technologies and Krill Oil

Once upon a time (in the late 1990’s) a Canadian biotech company called Neptune Technologies and Biosciences created one of the very first krill oils.

They claimed to have developed a secret cold-extraction process for making a highly-purified krill oil extract.  The manufacturing process was so proprietary that they have actually patented it in a number of different countries.

The end product was called Neptune Krill Oil (NKO) and it was the first and only krill oil whose health benefits were backed by clinical studies.

Neptune krill oil consists of the omega 3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in a phosholipid base, along with a powerful antioxidant.

Studies have found that this krill oil extract was more efficiently absorbed by the body while also offering enhanced free-radical protection and extremely high purity levels.

The krill oil business is highly competitive with global sales exceeding 204.4 million.  With so much money at stake, you can bet that each manufacturer will be claiming their product is better than the others.

A Closer Look at Neptune Krill Oil’s Ingredients

The krill oil market is a multi-million dollar business due to growing awareness and consumer demand.

While each manufacturer may have their own proprietary extraction and processing methods, all krill oils (regardless of brand name) will be made up of the following 3 ingredients.

1. Omega 3 Fatty Acids

  • Experts call these essential fatty acids because your body needs them for proper cell function. Your body uses them to make important hormones and they also have an anti-inflammatory effect. The main fatty acids in Neptune Krill Oil are EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid).

2. Phospholipids

  • Phospholipids are made up of phosphorous (a mineral) and lipids (a fat). Every one of your body cells are lined with a dual layer of phospholipids. They play a very important part in the maintenance and growth of all cells in your body.

  • It’s believed that the unique combination of phospholipids with the omega 3 fatty acids helps to increase absorption on a cellular level.

3. Antioxidants

  • All krill oils contain a substance called Astaxanthin, which is a naturally occurring carotenoid pigment and powerful antioxidant. You can find more detailed information and research studies at

  • In a nutshell, this powerful substance can play a vital role in cancer, cardiovascular diseases, eye health, neurodegenerative diseases, aging, immune response, exercise and more.

Here’s a close-up of an ingredient label of some Neptune Krill Oil (NKO).

The label shows the exact ingredients and amounts you’ll receive in two soft gels.

The 1000 mg. soft gels of Neptune krill oil provides 150 mg. of EPA and 90 mg. of DHA, along with 400 mg. of phospholipids and 1.25 mg of astaxanthin and other ingredients.

Due to Neptune Technologies’ patent extraction process, you’ll only find Neptune Krill Oil ingredients in this exact formulation.

While the dosage of EPA and DHA may seem low compared to many fish oil supplements, researchers believe that the phospholipids may actually help increase how well your body absorbs the EPA and DHA.

Is Neptune Krill Oil the Best Krill Oil?

Neptune krill oils are one of the better krill oils due to the actual research behind the development of this product.

Numerous studies on neptune krill oils have shown its ingredients help reduce inflammation in athletes and arthritis, reduces PMS symptoms and lowered triglycerides and cholesterol levels better than fish oil.

Another factor to consider is the patented technology that went into creating this highly purified product.

When Neptune Krill Oil was first released to the public, one of its main competitors in North America was Superba krill oil, made by Aker B (a Norwegian biotech company).

Superba Krill Oil is comparable to Neptune krill oils with regards to quality and purity.

However, Aker Biomarine recently bought out Neptune Technologies’ entire krill oil business. They now supply Neptune Krill Oil and Superba to North America and other parts of the world – making them one of the largest krill oil suppliers in the world.

Both Superba and NKO have their own proprietary and trademarked manufacturing process. We found there’s only a slight difference between the amount of active ingredients of both products.

And while there are dozens of different supplement companies that sell krill oil, only a small handful of products become as popular as Neptune krill oils.
