How We Ranked The Best Krill Oil Supplements

It’s easy to claim you make the world’s best krill oil supplement. However, there’s a big difference between cheap krill oil and premium krill supplements.

Here’s how our editorial team separated the best and worst krill oil supplements:

EPA and DHA Dosage and Ratio

You’re taking krill oil for the same reason you take fish oil: for omega-3 fatty acids. However, krill oil supplements have different EPA and DHA dosages and ratios. Some manufacturers specifically designed their krill oil to contain close to the clinical dose. Others hide dosages and ratios within proprietary formulas, making it difficult to see specific breakdowns.

Astaxanthin Dosage

Krill oil contains astaxanthin, a carotenoid with antioxidant effects. All krill oil contains natural astaxanthin. Some krill oil companies add astaxanthin or concentrate astaxanthin in their formula, while others hardly have any. In the list above, krill oil supplements contain anywhere from 200mcg to 3,000mcg of astaxanthin per serving. Astaxanthin appears to have significant antioxidant and inflammation-supporting benefits even at low doses.

Other Complementary Ingredients

We primarily judged krill oil supplements based on their omega-3 and astaxanthin content. However, we also considered complementary ingredients. Some krill oil supplements contained vitamin E, while others contained omega-7 and omega-9 fatty acids. These ingredients could complement the effects of your krill oil supplement.

Honest Advertised Benefits

Krill oil supplements won’t make you look ten years younger overnight, nor will they transform your heart and brain health. Instead, good krill oil supplement companies advertise real benefits and make realistic claims. They don’t try to dazzle you with absurd, unproven benefits. They let the natural science behind krill oil do the talking.

Sustainable Sourcing

Krill oil supplement companies emphasize sustainability. Most companies source their krill from the pristine waters of the Antarctic Ocean, where krill is abundant. We preferred krill oil supplement companies that disclosed their sustainable krill source upfront.

Certification and Third-Party Lab Testing

Some krill oil supplement companies invest in third-party lab testing, paying a lab to test their formula to verify it contains the advertised ingredients. Other companies partner with organizations like Friend of the Sea to certify sustainability. The more certification, third-party testing, and analysis a krill oil supplement had, we ranked it higher.

Price, Value, and Overall Cost

Some people want to spend $100 on a one-month supply of a krill oil supplement. Others want to spend $10. Whatever your budget, you should be able to get quality krill oil. If you’re buying a budget krill supplement, you shouldn’t need to compromise on quality ingredients or safety. If you’re paying for premium krill, you should get premium ingredients.

Manufacturer Reputation, Transparency, and Track Record

In the last few years, some supplement companies have sprouted up specifically to target the exploding krill oil market. Others have a proven track record of creating effective supplements for decades. We preferred manufacturers with a strong reputation for producing quality supplements, although we weren’t biased against newer startups with high-quality manufacturing processes.

Ease of Use, Taste, and Capsule Size

Most people don’t want to swallow a thumb-sized pill every day to get their omega fatty acids. Our rankings considered ease of use, taste, and capsule size.

Money-back or Satisfaction Guarantee

All reputable krill oil supplement companies backup their products with a 30 to a 90-day money-back guarantee. Some companies even offer 180 days to 365-day money-back guarantees. We preferred krill oil supplements with some money-back guarantee. It shows a manufacturer stands behind their product and is confident you’ll like it.

Doctor or Dietitian Formulated

The best supplement companies employ medical doctors (MDs), registered dietitians (RDs), and other certified professionals to create their supplements. The more professional experience was used to develop a krill oil supplement, the higher we ranked it.

Top 10 Benefits of Krill Oil

People take krill oil for various reasons – from anti-aging effects to heart health.

Here are some of the most popular benefits of taking krill oil:

  • Rejuvenate aging skin
  • Clear blurry vision
  • Help support heart health
  • Support good mood
  • Lose weight
  • Support memory and cognition
  • Restore joints and support joint pain relief
  • Boost metabolism
  • Get more omega-3 fatty acids and balance your omega fatty acid intake
  • Get fewer toxins than fish oil supplements due to less bioaccumulation

For all of these reasons and more, krill oil supplements have surged in popularity – and they show no signs of slowing down.

How Do Krill Oil Supplements Work?

Krill oil supplements work by providing your body with crucial levels of omega-3 fatty acids.

Your body can’t produce omega-3 fatty acids on its own. However, omega-3s are essential for heart health, brain health, inflammation, and other bodily processes.

Omega-3s are valuable because they contain two specific fatty acids:

  • Eicosapentaenoic Acid (EPA)
  • Docosahexaenoic Acid (DHA)

The primary source of omega-3 fatty acids is fish, krill, and other seafood. Our ancestors ate plenty of these foods, so our bodies evolved to need these ingredients.

Today, however, modern diets have too few omega-3s. Many of us aren’t getting enough fatty fish daily to provide us with the right amount of omega-3s.

The best sources of omega-3s include wild salmon, sardines, anchovies, herring, mackerel, and seafood.

10 Signs You Might Need More Omega-3 Fatty Acids

A lack of omega-3 fatty acids can lead to noticeable side effects. Some people develop dry skin, dry eyes, and poor joint health because of low omega-3 intake.

Some of the signs you might not be getting enough omega-3s include:

  • Dry, rough, or prematurely old patches of skin
  • Dry hair and dandruff
  • Brittle nails
  • Dry eyes
  • Difficulty focusing or concentrating, or a general “mental fog.”
  • Joint pain and general joint discomfort
  • Irritability
  • Mood swings
  • Fatigue and low energy
  • Poor sleep or unsatisfying sleep

If you are experiencing one or more of these symptoms, then a krill oil supplement may be able to help.

Krill Oil Versus Fish Oil

Many people take fish oil supplements daily for the purported benefits. Fish oil supplements aren’t inadequate, but many now prefer krill oil supplements.

Here are some of the differences between krill oil and fish oil supplements:

Krill Has More Omega-3 Fatty Acids

Many fish oils contain too few omega-3 fatty acids. Omega-3s are a family of healthy fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These acids play crucial roles in brain health, heart health, and inflammation. Your body can’t produce omega-3s on its own, and you must get them from your diet.

Krill Has Fewer Omega-6 Fatty Acids, Which is a Good Thing

Many of us get too many omega-6 fatty acids in our diet. Your body needs omega-6 fatty acids, but excessive omega-6 intake can lead to severe problems. Some people experience accelerated effects of aging because of excessive omega-6 fatty acid intake, for example. Your skin, nails, and hair might look older than your biological age because of an incorrect balance of omega-6 to omega-3 fatty acids. The typical American has an omega-6 to omega-3 ratio of around 15:1, while the ideal ratio is close to 4:1. Krill oil contains a better balance of omega-6 to omega-3 fatty acids, making it a superior choice.

Krill Has Cleaner, Higher-Quality Ingredients, and Fewer Toxins

Fish oil comes with cleaner ingredients and fewer toxins than krill oil. Many fish oil supplement companies use cheap sources of fish. Fish are also higher on the food chain, which means more toxins accumulate in their bodies than in krill, which are lower on the food chain.

Krill Has More DHA and Better DHA/EPA Ratios

Many fish oil supplements contain too little DHA or a suboptimal ratio of DHA to EPA. DHA and EPA are both essential for health. However, your body has 5x to 30x more DHA in its tissues than EPA. A DHA supplement may be better if you want higher DHA for maximum effect.

Krill Supplements Have Better Freshness and Less “Fishy Burps”

If you’ve ever taken a fish oil supplement, you may have experienced fishy burps. Some fish oil supplements taste fishy. Others have oxidized over time, increasing the risk of experiencing fishy burps. Krill oil supplements tend to have a better freshness and a more pleasant smell and taste.

Krill May Have Less Mercury and Fewer Heavy Metals

Some krill have less mercury than fish oil. Whether you’re buying fish oil or krill oil, it’s essential to pick a supplement that has limited methylmercury content. Methylmercury is a neurotoxin linked to brain and nervous system damage. It can also damage your kidneys, liver, and heart. Look for krill that has been tested for mercury and other toxins like PCBs, furans, heavy metals, and dioxins.

Krill Oil Versus Plant-Based Omega-3s

Some plant-based foods advertise high levels of omega-3 fatty acids. Plant-based omega-3s are popular, but they work much differently than animal-based omega-3 sources like krill.

Vegan Versus Non-Vegan

Plant-based omega-3 sources, like walnuts and chia seeds, are vegan and vegetarian friendly. Krill is an animal (a tiny type of fish), so krill oil supplements are not vegan or vegetarian friendly.


Plant-based foods contain a different type of omega-3 fatty acid called ALA. Your body converts a small amount of ALA into EPA and DHA, although it’s not an effective way to increase EPA/DHA intake (only about 0.5% gets converted). EPA and DHA are the two most important omega-3 fatty acids, and krill oil is much better than plant-based sources for getting those fatty acids.

Overall, plant-based sources of omega-3 fatty acids can be rich in vitamins, minerals, fiber, and protein, but they’re not good sources of omega-3 fatty acids.

Why is Krill Oil Purer and More Sustainable than Fish Oil?

Many people take krill oil because it’s purer and more sustainable than fish oil. A good krill oil supplement tends to have fewer toxins while being more sustainable than fish oil.

Some of the reasons for the difference in sustainability include:

  • Krill are further down the food chain than fish, which means they don’t accumulate as many toxins.
  • Fish are further up the food chain, which means more toxins accumulate in their bodies.
  • When you create a fish oil supplement, you’re condensing a specific extract of fish into a concentrated form, which could lead to significant toxic accumulation.
  • Most krill are sourced from the pristine waters of the Antarctic Ocean, thousands of miles away from significant human settlements.
  • Krill oil is more sustainable than fish oil. The world’s oceans are filled with krill. Krill have short lifespans, and they reproduce quickly. Even when harvested in high quantities, krill are abundant and remain abundant.

Overall, krill oil tends to be purer and more sustainable than fish oil.

Scientific Evidence for Krill Oil Supplements

Growing research indicates krill oil may be superior to fish oil for optimizing benefits. Both krill oil and fish oil supplements offer similar benefits, but research suggests krill oil may be better.

In this 2007 study, for example, researchers found krill oil supplementation was linked to a significant drop in inflammation. Researchers gave krill oil to a group of adults with arthritis. After taking krill oil, the adults experienced a considerable reduction in C-reactive protein levels, a biomarker linked to inflammation. Inflammation is associated with pain and discomfort.

Today, many people with arthritis and other types of joint pain take krill oil supplements to help. In one study, researchers gave krill oil to a group of adults with mild knee pain. After 30 days, participants reported a significant reduction in knee pain while standing and sleeping and a better range of motion.

Inflammation is also linked to disease. Some of the world’s deadliest diseases are linked to inflammation. In this 2013 study, researchers found krill oil lowered inflammation and boosted immune function. Researchers found krill oil reduced tumor necrosis factor-alpha (TNF-alpha), a biomarker associated with inflammation. Because of these results, researchers concluded that krill oil had significant anti-inflammatory and immune-boosting properties.

Other studies have reinforced the connection between krill oil, inflammation, and immunity. Researchers gave participants a 300mg krill oil supplement or a placebo in this study and observed significantly better inflammation in the krill oil group. In fact, after just 30 days of taking the krill oil supplement, the krill oil group had 30% better inflammation biomarkers than the placebo group.

Some people take krill oil daily to support cardiovascular health. Studies show krill oil can support heart health in multiple ways. For example, researchers found krill oil led to a significant drop in cholesterol in this study. Researchers gave a group of 300 adults a 0.5g to 4g krill oil supplement for 12 weeks, then observed substantial improvements in cholesterol readings. Krill oil led to a significant drop in serum triglycerides without increasing low-density lipoprotein (i.e., “bad” cholesterol).

Other studies have further validated the cardiovascular health-supporting benefits of krill oil. In this 2017 study, researchers performed a comprehensive review on krill oil and heart health, concluding based on multiple studies that krill oil can help reduce cholesterol safely.

Can a krill oil supplement boost cognition and brain health? Some studies suggest krill oil has significant effects on cognition. For example, in this study, researchers found EPA and DHA, the two primary omega-3 fatty acids in krill oil, protect the brain from inflammation and oxidative damage, both of which are associated with brain disease. In that same study, researchers found a correlation between those getting regular daily doses of EPA/DHA and a low risk of autism, depression, dementia, epilepsy, and schizophrenia, among other cognitive conditions.

Other studies have explored the connection between krill oil and depression. For example, in this study, researchers found krill oil supplementation reduced symptoms of depression and improved cognitive function.

Other studies have connected krill oil to benefits like reduced dry eye, improved symptoms of diabetes, and weight loss, among other effects.

Krill oil also contains astaxanthin, a natural carotenoid and an antioxidant that plays a crucial role in skin health, repair, and disease. In this 2018 study, researchers reviewed dozens of studies on astaxanthin, concluding that astaxanthin was linked to significant effects on skin health, repair, and disease. Astaxanthin appears to be particularly beneficial for UV-induced skin damage.

Meanwhile, other studies suggest astaxanthin has cardioprotective benefits. In this 2011 study published in Marine Drugs, researchers described astaxanthin as a “potential therapeutic agent in cardiovascular disease” for its effects on heart health and inflammation.

Astaxanthin is also one of the best antioxidants for eye health, so many people take krill oil supplements for eye health. As explained in this 2020 study, astaxanthin could be helpful in the treatment of ocular diseases, and multiple studies have connected astaxanthin to significant eye health benefits.

Overall, krill oil is a well-studied and science-backed supplement that appears to be associated with significant effects in multiple studies.

Krill Oil Side Effects

When healthy adults use standard dosages, Krill oil supplements are not associated with significant side effects.

However, uncommon and mild side effects may include:

  • Fishy breath or fishy burps
  • Bloating
  • Upset stomach
  • Constipation or diarrhea
  • General digestive issues

Follow the recommended dosage instructions on your krill oil supplement. Because supplements contain different dosages and concentrations, it’s essential to follow the dosage recommended on your supplement.

Some studies suggest krill oil could interact with blood-thinning medication and slow blood clotting. Talk to your doctor before taking krill oil if you take medication or have any disease or illness.

Recommended Dosage of Krill Oil

Most krill oil supplements contain 500mg to 1,500mg of krill oil per serving, giving you 50mg to 250mg each of EPA and DHA.

This is similar to the dose used in most clinical studies.

According to the American Heart Association, you should consume a minimum of two 3.5 oz servings of fatty fish per week to get your optimal dose of omega-3 fatty acids. Fatty fish include wild salmon, sardines, anchovies, herring, mackerel, and other seafood (including oysters and mussels).

The AHA also recommends getting 250mg to 500mg of EPA and DHA per day.

Studies show different doses of krill oil have other effects. In this 2014 study, for example, researchers tested the effects of 0.5g, 1g, 2g, and 4g doses of krill oil. Researchers observed significant benefits at all doses, although they did not see a specific correlation between high doses and low doses in terms of greater or lesser benefits. In other words, getting 0.5g or 4g of krill oil daily may be equally as effective.
