Our guide to the best, purest and most effective krill oil supplements in the market.


You may have heard about krill oil on the market or in the media lately, but do you really know the benefits? Is it simply the same thing as fish oil? 

Well, we’ve got the inside scoop for you on all things krill oil and how you can incorporate this supplement into your life to begin experiencing some wonderful health benefits!

What is a krill oil supplement?

First thing’s first, you need to know where krill oil comes from. Krill are tiny crustacean that dwell in the oceans of the world and are food for many large sea mammals like whales, seals and penguins.

They basically look like a minuscule shrimp and can grow anywhere from 10mm-20mm.

Krill are actually said to make up the largest biomass on earth, which makes them a great, ecologically-sustainable resource.

Krill are optimally harvested from the deep, freezing Antarctic waters and are most likely from the species, Euphausia superba.

As they’re harvested from such pristine waters, there is less chance of toxins and mercury being inside their systems than you would see with many other fish oils.

How can a krill oil supplement benefit me?

The best thing about krill oil is how rich it is with omega-3 fatty acids, something that the body cannot produce on it’s own but is essential for human health.

The reason they’re so loaded with these fatty acids is because the krill actually feed on algae which is a natural source of omega-3’s.

Within these omega-3’s there are docosahexaenoic (DHA) and eicosapentaenoic (EPA) acids, which along with the less beneficial alpha-linolenic acid, make up the trifecta for health. Here are the exact benefits you can expect from krill oil:

1. Easier to absorb than fish oil

This is an important one, krill oil is attaches itself to phospholipids in your system instead of triglycerides (as fish oil does), this basically means that your body is able to absorb it quicker and more efficiently.

This means that the dose you take can be significantly smaller than normal fish oil, but you’ll still get the same benefits.

2. Reduces and prevents inflammation

Basically, the omega-3’s in krill oil can be converted into eicosanoids which encourage your body to release anti-inflammatory chemicals called prostaglandins.

As inflammation is prevalent in almost every disease and illness, combatting this is extremely important in giving your body the best chance to stay healthy.

3. Can help fight mental disorders

Omega-3’s have been shown to help in reducing and preventing the progression of mental disorders by boosting dopamine and serotonin levels. Such disorders include:

  • Anxiety
  • Depression
  • Schizophrenia
  • Alzheimer’s
  • ADHD

4. Lowers cholesterol to improve cardiovascular health

Krill oil’s high dosage of omega-3’s is known to assist with lowering bad cholesterol levels, reducing triglycerides and increasing the good cholesterol in your body to improve overall cardiovascular health.

A research study conducted over 12 weeks showed a 13%-18% reduction in cholesterol, an amazing difference! It also reduces the chance of heart attack in diabetic individuals and can lower their insulin resistance.

5. Reduces symptoms of PMS

A great one for all the ladies out there that suffer from premenstrual syndrome (PMS) around that time of the month.

Scientists aren’t exactly sure why omega-3’s help with PMS but studies suggest it may have something to do with keeping hormones in balance.

It may also be because EPA and DHA are able to combat mood deficiencies such as fatigue and depression.

6. Contains the antioxidant astaxanthin

This is something that fish oil generally lacks, astaxanthin is an antioxidant found in krill oil that protects EPA and DHA from oxidising and losing potency.

It won’t give you the benefits that normal antioxidants do as the levels are too low, but you know your krill oil will be well protected whilst in your body and out of it, ensuring maximum benefits.

7. Fights autoimmune diseases

Diseases where the immune system attacks healthy cells by mistaking them for harmful ones, are particularly hard for doctors to diagnose and treat.

Lupus, rheumatoid arthritis, type 1 diabetes, multiple sclerosis and more can be combated with omega-3’s and have been linked with an alleviation of symptoms.

8. Inhibits growth of cancer cells

A lot of research has been undertaken regarding omega-3’s effect on cancers, it’s been found that some cancers will respond positively by slowing or reversing growth of the cells especially in hormonal cancers and colorectal cancer.

As krill oil is so rich in omega-3’s and works so well in the body with little adverse effects, the oil has shown promising results in preliminary studies.

These are just some of the amazing benefits of krill oil, it can also help with dry eyes, neurological development in infants when consumed by pregnant mothers and prevents obesity by blocking the endocannabinoid pathways to control hunger.

As an added bonus, they generally taste a lot better than fish oil supplements and come in an easier to swallow, smaller dose tablet. In many cases this will still provide the same benefits of a high dose of fish oil.

The only downside to krill oil is that this supplement can be a bit more expensive than fish oil due to the need for a speedy production process to ensure potency.

Tips and tricks for purchasing krill oil supplements

Check where they’re harvested from

You want to make sure your krill is coming from the purest waters possible so that you skip all the nasty toxins and mercury that can be found in the oceans and make it into sea creature’s systems.

Krill harvested from Antarctica in an ecologically sustainable way is the best kind, don’t settle for anything less!

Check the omega-3 content

This is going to be your main source of health benefits so you want this number to be as high as possible per serving. The best brands will list the concentration of your omega-3’s with the broken down EPA, DHA and astaxanthin listed as well.

Serving size

Go for the largest serving size possible as long as it contains all the necessary ingredients, at least 1000 milligrams is a good place to start.

Make sure the serving size is per capsule, instead of being 2 capsules’ worth – this is any easy way to be tricked into buying a less potent product.

Phospholipid count must be high

The main difference between fish oil and krill oil is that krill oil can come in phospholipid form. Try to get a krill supplement with the highest amount of phospholipids to ensure maximum absorbency into your body.

Steer clear of toxins, chemicals and additives

Make sure that the brand you’re getting your krill oil from does not use any harmful additives or allergens to fill out their capsules or tablets.

If you can, get a brand that uses an extraction and production method that doesn’t expose the supplement to any harmful toxins or chemicals.
