Fish oils reigned supreme till recently as the best source for omega-3s. But now, there is a new entrant in the market that has overtaken fish oils and that’s none other than Krill oil!

Krill is a tiny marine animal that resembles a shrimp and is found in the open oceans. Derived from the Norweigian word ‘krill’ meaning ‘a small fry of fish’ these crustaceans contain fatty acids that are most beneficial for health.

Antarctic krill refers to the Euphausia Superba species found in the Southern Ocean surrounding the Antarctic continent. Krill oil, the extracts from krill contains 2 main components of Omega-3 fatty acids – EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid).

Numerous studies on EPA and DHA fatty acids indicate that they can bestow multiple health benefits including cardioprotective effects, good fetal development, treating inflammatory conditions, improving cognitive functions in Alzheimer’s Disease, and many more (1).

Krill oil also has another important carotenoid, Astaxanthin, which is best known for its antioxidant power and potential pharmacological properties (2).

Krill oil supplements are one of the best ways of obtaining these health-benefiting nutrients. They are available as liquids, soft gels, capsules, etc, and can be purchased online without the need for a prescription.

Dosage for Krill Oil Supplements

Though one can get Omega-3s from consuming seafood, supplements may be a better option to get these nutrients quickly and efficiently. Dosage of Krill Oil supplements may vary according to an individual’s requirement or the medical condition for which it may be recommended.

Research indicates that tolerable doses of DHA and EPA from supplements were between 250-500 mg/ day. Certain conditions may benefit from a 1 g/day dose, but it is not recommended to exceed 5000 mg/ day in long-term supplementation to avoid adverse effects (3).

Krill oil is considered to enhance heart health. Studies have shown that krill oil of 600 mg did not have any adverse effect and resulted in an increase of Omega-3 fatty acids in the body which may help lower the risk of Cardiovascular Diseases (CVDs) (4).

Omega-3 fatty acids especially DHA are proven to aid in brain development in infants. A study on the effect of Omega-3s via krill oil in lactating women indicated that a one-month supplementation of 250 gm significantly increased EPA and DHA levels in breast milk (5).

It is always best for pregnant women and individuals with other medical conditions to seek a practitioner’s advice to determine the suitability and appropriate dosage for the best benefits.

Summary: The dosage of krill oil supplements can vary depending on requirements. While tolerable doses have been identified, it’s best not to exceed 5000 mg/day and seek a practitioner’s advice to check suitability and dosage.

Risks and Side Effects of Krill Oil Supplements

Krill oil supplements are natural and contain essential fatty acids that the body needs and can use effectively. Generally considered safe, it is wise to understand some risks and side effects that might be involved before using them.

Some of the points to keep in mind are:

  • Krill oil supplements can create digestive discomforts such as bloating, fish-smelling burps, diarrhea, reduced appetite, or nausea.
  • Interactions with warfarin, an anticoagulant, have been noted in the use of high doses of fish oil supplements. Since krill oil has similar properties, it is advised to exercise caution or consult a doctor if you are under such medications (6).
  •  If you are allergic to fish or shellfish, krill oil supplements should be completely avoided as they can trigger nasty reactions.

Summary: Krill oil supplements can result in stomach-related issues in some people. People allergic to shellfish, using anticoagulants or with other medical conditions, and pregnant women can seek a doctor’s advice before using these supplements.

Frequently Asked Questions (FAQs)

How is krill oil different from fish oil supplements?

There are two main differences between krill oil and fish oil supplements. One is, the omega-3 fatty acids in fish oil available as triglycerides and those in krill oil are in the form of phospholipids. Studies suggest that krill oil has a higher bioavailability than fish oil (7).

The second difference is krill oil is rich in the antioxidant, astaxanthin, which also provides the oil with a deep red color. Astaxanthin is only found in salmon or trout and is not common to fish oil.

How soon can I see the benefits of taking a krill oil supplement?

Visible benefits from taking a krill oil supplement are dependent on the deficiency in your body’s omega-3 levels.

Supplement intakes may start showing benefits anywhere between 6 weeks to 6 months. A blood test can affirm an increase in your Omega-3 index after 3 months of supplementation.

The Final Note

Krill oil is derived from a shrimp-like marine animal and Antarctic Krill is more popular for making supplements. These supplements are considered beneficial owing to their omega-3 fatty acids and astaxanthin that confer a host of health benefits in supporting heart, brain, and joint health.

Krill oil supplements are available as liquids, capsules, or soft gels and enable a stable increase to omega-3 levels in the body. Depending on the individual, they are recommended in doses between 250 mg – 1 g/ day for different medical conditions.

Apart from a few side-effects and individuals with shellfish allergy who need to avoid these supplements, krill oil supplements can be taken on the advice of a practitioner to help promote good fatty acids and antioxidant levels in the body for healthier living.
