How We Ranked

All astaxanthin supplements, whether krill oil or fish oil, claim to offer big doses and benefits. However, astaxanthin-rich supplements vary widely in effectiveness. Our editorial team used the following to separate the best astaxanthin supplements from the merely average:

Dosage: We considered the overall astaxanthin dosage in each supplement. Generally, a bigger number is better. You’re taking a astaxanthin supplement because you want more krill oi, so high doses are important.

EPA/DHA Dosage: A big krill oil dosage isn’t everything. We also considered EPA and DHA dosage. EPA and DHA are the two omega-3 fatty acids in krill oil, and they’re responsible for certain benefits of astaxanthin antioxidants.

Astaxanthin Dosage: Krill oil naturally contains an antioxidant called astaxanthin. Some supplements contain added astaxanthin, while others contain only trace amounts. The more astaxanthin, the more effective krill oil’s antioxidant and anti-inflammatory effects may be.

Label Transparency: Reputable astaxanthin health supplements break down each specific ingredient, labeling the specific amount of EPA, DHA, and other fatty acids. Some krill oil supplements are deliberately vague about dosages, which typically means they have smaller doses than competing supplements.

Lab Testing: Some supplements work with independent labs to verify ingredients. Other supplements have no testing whatsoever. Which supplement would you rather have in your body?

Price & Value: Astaxanthin supplements generally offer good value, supporting certain aspects of health without costing a fortune. We featured a range of krill oil supplements at all values, although we were careful to consider value across all supplements.

Ingredient Sources: Most astaxanthin supplements source their krill from the Antarctic Ocean, although some krill oil supplements do not disclose ingredient sources.

Manufacturer Reputation: Does the manufacturer have a long and proven reputation of making high-quality supplements? Or is the manufacturer simply whitelabeling someone else’s formula or capitalizing on krill oil hype?

Advertised Benefits: It’s illegal for supplements to advertise specific health benefits. Some supplements are careful with how they advertise health benefits, refusing to mention specific health effects. Other supplements don’t seem to care. We emphasized supplements that were open and honest with their advertised benefits.

Inactive or Other Ingredients: Some astaxanthin supplements contain excessive fillers or binders. Others contain as few inactive ingredients as possible. We prefer supplements with safe, inactive ingredients and no fillers.

Fishy Taste / Burps: Some astaxanthin supplements taste and smell like fish, giving you unpleasant, fishy burps. Other krill oil and fish oil supplements taste better and do not give you fishy burps. We considered taste when ranking the best astaxanthin supplements.

Freshness: Freshness is important with astaxanthin supplements. Astaxanthin supplements can (and will) expire. The most popular astaxanthin supplements emphasize freshness without overloading the formula with preservatives.

Who Should Take an Astaxanthin Supplement?

People take astaxanthin-based supplements for different reasons. Maybe you’ve heard of the power of fish oil and want similar benefits – but without the downside.

People take krill oil to support cardiovascular health. Many doctors recommend taking fish oil to support your heart. Krill oil contains the same EPA and DHA omega-3 fatty acids that give fish oil its heart health-boosting benefits.

Others take krill oil to support cognitive or brain health. Fatty acids appear to have a neuroprotective effect, supporting your brain and nerve cells against degradation.

There’s also some evidence that fish oil improves rheumatoid arthritis and osteoarthritis symptoms. Some take krill oil to relieve pain, stiffness, and mobility issues.

A good immune system requires a balanced body. Astaxanthin can support multiple aspects of health to ensure a strong immune system. Some studies have found that krill oil reduces inflammation, for example, which can make it easier for your immune system to function.

Most people associate krill oil with heart, brain, or joint benefits. However, some people take it for other surprising purposes.

Some take krill oil to ease symptoms of premenstrual syndrome (PMS), for example, because krill oil was shown to reduce PMS symptoms and PMS-related pain.

Others take it for weight loss.

Some pregnant women take krill oil because it purportedly has a beneficial effect on a developing child’s brain. Some parents give krill oil to young children fort he same reason.

Krill oil is popular among men and women of all ages. Health experts recommend that people of all ages get an adequate intake of omega-3 fatty acids, which is why krill oil is popular among all groups.

Science is surprisingly supportive of krill oil. Below, we’ll discuss some of the studies that verify the benefits listed above.

Benefits of Astaxanthin

Benefits of Astaxanthin

Krill oil comes from krill, which are tiny, shrimp-like creatures. They live primarily in cold, clean ocean waters. Today, the world’s largest krill oil manufacturers harvest krill from the deep, pristine waters of the Antarctic Ocean. This type of omega-3, DHA and EPA orange-colored compound oil is rich in astaxanthin.

The Antarctic Ocean is remote. It’s far away from industrial pollution and toxins. Plus, krill have short lifespans, which means they don’t have time to build up toxins – like fish with longer lives that build up mercury. Krill are also at the bottom of the food chain, which means they do not accumulate toxins from the foods they eat. For all of these reasons, krill oil may have significantly lower levels of toxins than fish oil.

Studies show that krill oil has similar benefits to fish oil – but with better absorption. Like fish oil, krill oil contains the omega fatty acids EPA and DHA. These fatty acids are linked to better heart health, reduced joint pain, reduced inflammation, and other benefits. Krill oil has not been studied as extensively as fish oil, although studies suggest that krill oil could be superior. We have 20+ years of studies verifying certain benefits of krill oil.

Many of krill oil’s benefits seem linked to inflammation. The omega-3 fatty acids in krill oil may reduce inflammation. Krill also have a pinkish-orange pigment called astaxanthin. That pigment appears to have powerful antioxidant and anti-inflammatory benefits of its own.

Fatty acids and astaxanthin seem to fight inflammation in two ways. It’s not always clear which ingredient has which anti-inflammatory benefit, so we’ll just refer to it simply as krill oil.

Krill oil reduces levels of CRP or C-reactive protein. Your immune system uses this protein to fight infections. Reducing this protein may seem like a bad thing. However, higher CRP levels lead to higher inflammation.

This randomized controlled trial from 2007 found that people suffering from arthritis who took krill oil supplements experienced a significant drop in CRP (inflammation) levels. In a 2013 study, krill oil lowered inflammation by reducing tumor necrosis factor alpha (TNF-a), a biomarker for inflammation. Based on the results of these studies, it seems possible krill oil has significant anti-inflammatory effects.

We’ve seen similar effects in other studies. This study analyzed the effect of krill oil on cholesterol, but found participants also experienced anti-inflammatory benefits. Participants took 1,000mg of krill oil per day, showing a significant improvement in inflammation markers. In fact, researchers found that 1,000mg of krill oil was more effective than 2,000mg of omega-3 supplement.

In this study, meanwhile, people with chronic inflammation took 300mg of krill oil supplement for 1 month, then experienced a 30% drop in inflammation.

Many people take krill oil to reduce joint or arthritis pain. Again, these effects seem linked to krill oil’s effects on inflammation. By acting as an anti-inflammatory, krill oil may relieve joint pain and arthritis symptoms. That means more mobility and flexibility.

In this study, adults with mild knee pain took krill oil supplements for 30 days, then noticed a significant reduction in knee pain while standing and sleeping. Participants reported a greater range of motion after 30 days of supplementation.

We need more research on humans to verify the anti-arthritis benefits of krill oil. However, early research is promising – especially on animal studies. In this study, researchers gave krill oil to mice with arthritis, then noticed reduced inflammation, less joint swelling, and improved arthritis scores. Because of all of these factors, krill oil has been suggested as an effective treatment for joint pain and arthritis.

Many people take krill oil or fish oil supplements to support cardiovascular health. The fatty acids in krill oil seem to have a beneficial effect on heart health, reducing blood lipids (cholesterol) and making it easier for your heart to function. Many doctors recommend taking EPA and DHA for heart health.

This study found that krill oil was particularly effective for reducing triglyceride levels. The randomized controlled trial published in 2014 found that krill oil supplementation lowered serum triglycerides without increasing low density lipoprotein cholesterol (LDL or ‘bad’ cholesterol). 300 adults took a krill oil supplement for 12 weeks. Adults took 0.5, 1, 2, or 4g of krill oil per day or a placebo (olive oil). Researchers found a significant reduction in cholesterol in the krill oil group compared to the placebo.

This study in 2017 echoed those heart health boosting results. Researchers found that krill oil supplementation had lipid-modifying effects. Researchers analyzed dozens of studies on krill oil supplementation. After reviewing evidence, researchers concluded that “krill oil supplementation can reduce low-density lipoprotein cholesterol and triglycerides”.

Some women take omega-3 fatty acids to manage symptoms of PMS. Studies have analyzed this effect and found surprising results. This study from 2003 found that krill oil could relieve symptoms of PMS like depression, fatigue, irritability, and mood swings. Researchers also found that krill oil reduced the use of pain killers. In a similar study from 2012, women took one omega-3 capsule daily for 3 months, then experienced a significant reduction in pain during periods.

So far, we’ve mostly talked about the physical effects of krill oil. However, krill oil appears to positively impact cognitive health as well. Some studies have shown that krill oil fights depression, for example, and supports other aspects of brain health.

This study published in Nutrients in 2014 found that DHA and EPA omega-3 fatty acids in krill oil can protect the brain from oxidative damage and inflammation, reducing the risk of certain brain diseases. Researchers believe these neuroprotective effects can reduce the risk of autism, dementia, depression, schizophrenia, and epilepsy, among other conditions. The 2014 study also found a connection between krill oil supplementation, cognitive function, and memory formation.

Other studies have connected krill oil to reduced symptoms of depression. This 2013 study found that people taking a krill oil supplement enhanced cognitive function and experienced antidepressant-like effects. The study was performed on rats – not humans.

Could krill oil reduce symptoms of diabetes? One study found that type 2 diabetics experienced a significant improvement in insulin sensitivity levels after taking a krill oil supplement for 4 weeks. Based on the results of that study, krill oil could help to reduce blood sugar levels, making it easier for diabetics to manage diabetes symptoms.

Some use krill oil as weight loss aid. This study in 2012 examined the effect of omega-3 fatty acids on obesity. Researchers found that EPA and DHA supplementation affected appetite, food intake, fat mass, and eating behavior, all of which are linked to obesity.

Krill oil could prevent dry eye. In fact, many people with dry eye have low levels of omega-3. Taking a krill oil supplement could reduce dryness. In this study published in 2017, researchers tested that hypothesis by giving people with dry eye a krill oil supplement for 90 days. Participants showed a reduction in inflammation and redness in the eye and improved tear production.

Some take krill oil to reduce symptoms of colitis. Colitis is a condition where your colon is inflamed. Researchers believe krill oil reduces symptoms of colitis by targeting inflammation. Krill oil is packed with antioxidants that could reduce inflammation and oxidative damage in the colon.

Krill Oil vs. Fish Oil

Curious about the difference between krill oil and fish oil? Many people take krill oil because they believe it offers similar benefits to fish oil – but with better absorption or fewer harmful effects.

Differences between krill oil and fish oil include:

Absorption: Your body may absorb krill oil more effectively than fish oil. Both krill and fish oil contain omega-3 fatty acids EPA and DHA. In fish oil, these fatty acids are bound to triglycerides, making them harder for the body to absorb. In krill oil, they’re bound to phospholipid molecules that are easier for your body to absorb. Studies have confirmed this benefit. One study found that your body absorbs krill oil 68% more effectively than fish oil. That means you need 2/3rds as much krill oil to get an equivalent dose of fatty acids.

Astaxanthin: Krill oil contains an antioxidant called astaxanthin. Astaxanthin is linked to several benefits of its own, including anti-inflammatory properties and improved overall health and wellness. Multiple studies have found that astaxanthin boost the immune system, for example, and prevents DNA damage. Other studies have linked astaxanthin to cardiovascular health because it decreases triglycerides and increases HDL, balancing cholesterol in your blood. Some people take astaxanthin supplements on their own, so it’s a bonus that krill oil contains extra astaxanthin.

Tocopherol: Krill oil contains a natural chemical called tocopherol, which prevents oxidation (similar to antioxidants like astaxanthin). Krill oil may have longer shelf life because it contains astaxanthin and tocopherol.

Better Safety & Fewer Toxins: Krill oil may be safer to take than fish oil. Krill oil supplements have lower tested levels of mercury and other toxins. Supporters argue that krill oil comes from clean, fresh, and cold water in remote parts of the world – like the Antarctic Ocean. That means the krill have fewer toxins when harvested. Fish oil, meanwhile, may be harvested in areas with industrial pollution. This toxic load may not be huge, but when creating a concentrated formula, toxins can quickly build up.

Sustainable Harvesting: Krill are abundant. They quickly reproduce, and they have a short lifespan. They’re easy, affordable, and safe to harvest in large quantities, making krill oil more sustainable than fish oil.

It’s not just hype: studies have shown that krill oil could be twice as effective as fish oil – or better. This study found that 1,000mg of krill oil supplementation per day was more effective than 2,000mg of omega-3 supplements.

Astaxanthin Dosage

Astaxanthin Dosage

Krill oil dosage varies between studies. With some supplements, you take different doses for different benefits. With krill oil, there doesn’t seem to be a significant difference in benefits between dosages.

Health authorities have set different guidelines for omega-3 fatty acids.

The American Heart Association (AHA), for example, recommends getting 250mg to 500mg of EPA and DHA (total) per day.

A 1,000mg krill oil capsule contains approximately 250mg of EPA and DHA, which means you can meet dosage recommendations with 1 or 2 capsules.

In this 2014 study, researchers gave participants 0.5, 1, 2, and 4g doses of krill oil per day. They noticed benefits at all dosages.

Studies have shown that krill oil is more effective than fish oil. Your body absorbs it more efficiently. If you’re used to taking a fish oil supplement, then you may need just 1/2 or 2/3 of krill oil for an equivalent dose.

Follow the dosage instructions on your krill oil supplement, and talk to your doctor before taking any supplement.

Side Effects

Krill oil is well tolerated by healthy adults when taking a normal dose and following recommended instructions. Few serious side effects have been reported.

However, krill oil could interact with blood thinning medication. Krill oil can slow blood clotting. You should not take krill oil within 2 weeks of surgery.

Common side effects of krill oil include:

  • Fishy breath
  • Fishy burps
  • Upset stomach
  • Bloating
  • Constipation
  • Diarrhea
  • Other digestive issues

Overall, krill oil is well tolerated by most people when taken in normal dosages. However, more research is needed to verify its safety among all groups. Women who are pregnant or nursing, for example, should talk to a doctor before taking krill oil.

Frequently Asked Questions About Astaxanthin

Krill oil supplements have been popular for many years, but the niche industry is still pretty rife with misinformation. This section will answer some of the most commonly asked questions about krill oil and related supplements.

Q: What is Krill Oil's Astaxanthin Contents?

A: Astaxanthin is a substance derived from a shrimp-like crustacean called krill oil or similarly fish oil. It contains the same two fatty acids (EPA and DHA) as fish oil. Krill oil is generally marketed as a substitute for fish oil, and some people swear by krill oil as the preferable supplement between the two and both are thought to be the richest sources of astaxanthin.

Q: What is an Astaxanthin supplement?

A: Most astaxanthin supplements contain a condensed or concentrated version of krill oil, typically packaged into a capsule or tablet. Krill oil supplements may be far easier for you to ingest than krill oil directly, and krill oil capsules can also help you to better regulate dosages and amounts.

Q: What is krill?

A: Krill are small, shrimp-like planktonic crustaceans that live in the open ocean. They’re the primary food source of certain larger mammals, including baleen whales.

Q: Can humans eat krill?

A: Most humans consume krill in the form of krill oil – they don’t eat krill itself. Krill are tiny and would have limited nutritional value on their own. Eating live krill could also be very dangerous, especially as they can carry diseases.

Q: What does krill mean?

A: The word ‘krill’ comes from the Norwegian word krill, which means ‘small fry of fish’.

Q: What should you look for in a Astaxanthin supplement?

A: Good krill oil supplements contain a high dose of krill (1,000mg or higher) with strong doses of EPA, DHA, and astaxanthin. Too little krill content within your supplement could keep you from reaping the benefits of the krill oil, while too much could even be potentially harmful.

Q: Where does krill oil come from?

A: Most krill oil comes from krill harvested in the Antarctic Ocean.

Q: How do you take a krill oil supplement?

A: Most krill oil supplements are oral supplements. You swallow a capsule or tablet. Krill oil is taken differently, so be sure to consult the package for a given krill oil product before using it.

Q: Why does krill oil have fewer toxins?

A: Krill oil may have less toxins for three reasons. First, krill oil is sourced from pristine, deep waters of the Antarctic Ocean, which are far away from industrial pollutions around populated areas. Second, krill have short lifespans, which means they don’t have a chance of accumulating too many toxins during their lifespan. And third, krill are at the bottom of the food chain, which means they don’t accumulate toxins from organisms lower down the food chain. For these reasons krill supplements are often touted as having fewer toxins (like mercury) than fish oil and other supplements.

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

A: Krill oil comes from small, shrimp-like creatures called krill, while fish oil comes from other fish sources. The fatty acids in krill oil are surrounded by different molecules, and studies show these fatty acids are easier for your body to absorb. Krill oil also contains an antioxidant called astaxanthin linked to various benefits.

Q: Is fish oil better than krill oil?

A: Studies show your body absorbs krill oil more easily than fish oil. In fact, you may need just 1/2 to 2/3 of the dose of krill oil compared to fish oil, based on bioavailability. Krill oil also contains astaxanthin, an antioxidant linked to anti-inflammatory effects.

Q: Is krill oil more sustainable?

A: Krill oil is more sustainable than fish oil. Krill are abundant in the world’s oceans. They reproduce quickly and have short lifespans. Most sustainability experts agree that krill oil supplements are significantly more sustainable than fish oil supplements.

Q: Why is krill oil more sustainable?

A: Krill are among the most abundant creatures on the planet. They have short lifespans and are common throughout the world’s oceans. While fish oil supplements have had a significant effect on global fish populations, krill oil supplements have not.

Q: Why does the body absorb krill oil more effectively than fish oil?

A: Krill oil contains phospholipids, which are good fats that enhance absorption. Fish oil does not contain phospholipids.

Q: Where does krill oil come from?

A: Most krill oil supplements harvest krill from the deep, pristine waters of the Antarctic Ocean.

Q: When’s the best time to take krill oil?

A: Many people take krill oil supplements in the morning, allowing your body to enjoy the effects throughout the day. Others split krill oil into two daily dosages, allowing the body to absorb it constantly over a 24 hour period.

Q: How does krill oil work?
