We’re all familiar with the health benefits of fish, as it’s long been deemed brain food. When comparing krill and fish oil, however, there are some clear differences. Krill oil increases your intake of omega-3 fatty acids, significantly benefiting your heart and brain.
Omega-3 fatty acids are healthy fats which are often sourced from seafood, helping to regulate immune function, organ function, heart health, overall cholesterol and, of course, brain health. Acting as brain boosters, omega-3 fatty acids support the maintenance of cell membranes.
In turn, both memory and reasoning are strengthened. Acting as a strong antioxidant, krill oil is an excellent neuroprotective aspect of any diet. Let’s focus on some of the key benefits associated with krill oil, how it works to boost positive health, and why this supplement trumps standard fish oils.
What is Krill and What Does It Offer?
Omega-3 fatty acids are considered to be essential fats, as our bodies cannot produce them. In order to benefit from their effects, we need to consume them within our diet or through supplementation. Essential fats, such as linolenic acid, are compounds in which your body needs in order to regulate optimal cellular health.
These acids form complex omega-3 fatty acids, containing unsaturated fats, such as EPA and DHA. Using these acids, our bodies are able to maintain strong, healthy cell walls throughout the body. These acids have been linked to immunity, skin health, cardiovascular health, brain health, and more.
Although you will find omega-3 fatty acids in some plant-based foods, such as flax and walnuts, the best sources are found in fresh fish and other sea life. Among all the creatures in the sea, krill contains the highest concentrations. This shrimp-like crustacean is highly potent in omega-3, providing incredible benefits.
These crustaceans are so widely abundant, as well, representing the largest biomass on our planet. Although this is only an estimate, sources say that there may be as much as 500 million tons of krill across all oceans. Being a common source of food and nutrition, over 100,000 tons are harvested each year for consumption.
Based on its numbers and abundance, this species is not threatened by overfishing. At this time, it’s considering a renewable energy source, compared to other fish who’s numbers are becoming increasingly threatened.
Being less than five centimeters long, krill live in cold oceans, such as the Antarctic and Pacific. Throughout Asia, they’re a traditional food and also recently become a popular supplement based on cognitive enhancement. The oil that’s extracted from krill is sold worldwide as a powerful supplement, benefiting mental and physical health
How Does Krill Oil Reach the Brain?
After consumption, the omega-3 fatty acids found in krill are transported through the body. Both EPA and DHA cross the blood-brain barrier, where it becomes available for neuron walls. In turn, the vitality of cell membranes increases, making these walls more permeable. This positively impacts the transport of nutrients while supporting the removal of waste and toxins.
The key effect in the brain is that omega-3 enhances communication efficiency. Receptors become more responsive and synapses become more plastic, adapting to the brain’s changing needs. We know that DHA and EPA levels in krill oil benefit the brain, but phospholipids also yield antioxidant properties.
Since antioxidants help reduce free radical damage, brain cells are better protected. When oxidation occurs in the brain, this is when cellular function deteriorate and potential brain damage occurs. The key component found within these phospholipids is phosphatidylcholine, an essential nutrient for brain health
Krill Oil vs. Fish Oil, What’s the Difference?
So, why not just take fish oil? For many years, fish oil supplements were the only available source of omega-3 fatty acids. Capsules filled with fish oil from cold-water species were the only option. Although these supplements also yield benefits, the demand for krill oil has spiked based on two key differences.
For starters, krill oil has a higher antioxidant content than fish oil. Meaning, it’s superior when protecting the brain against age-related decay. This is especially true within the brain. Secondly, krill oil does not perish like fish oil does.
Over time, fish oil breaks down, producing harmful free radicals. When consuming these free radicals, you essentially counteract the purpose of supplementation in the first place. Krill oil lasts longer and is more versatile, offering high concentrations of vitamins A, E, and D.
What Are the Benefits of Krill Oil?
Krill oil is known for a range of benefits, including enhanced functioning throughout numerous systems. It has been shown to boost immune function, liver function, skin health, and promote circulation. Joints become more flexible and symptoms of arthritis are alleviated.
Not only does it lower cholesterol, but it yields strong anti-aging properties, protecting against decay associated with the aging process. Based on its skin benefits, visible signs of aging such as wrinkles, are reduced as well. It also acts as a natural mood booster, cognitive enhancer, and may be used as a potential treatment option for those with ADHD.
While focusing on the brain, krill oil not only protects brain health, but it protects neural tissue. In turn, better brain functioning is experienced, resulting in an increased attention span, heightened concentration, and higher memory functioning. Based on its mood-boosting effects, symptoms of depression and anxiety can also be reduced.
Taking Krill Oil Safely
When it comes to side effects of krill oil, the majority are not harmful. For instance, some individuals will experience fishy breath, fishy taste in mouth, or the aroma of fish in one’s sweat. These effects are more closely correlated with fish oil and are not generally reported when taking krill oil.
In some rare cases, individuals experience mild side effects, such as digestion issues and heartburn. If you have an allergy to shellfish, it’s important to speak with your doctor before use. At this time, krill oil doesn’t appear to antagonize a shellfish allergy, but it’s also best to maintain caution.
How Much Kill Oil Should I Take?
To achieve optimum health, consuming daily doses of krill oil will help you experience various health benefits. Daily doses ranging between 1000 and 2000 mg per day are often recommended. These amounts are approximately half the amount of regular fish oil when aiming to achieve similar effects.
Like any new supplement, start with the lowest doses. That way, you will better understand how krill oil affects your stomach. If you do not experience a sensitivity, you can gradually increase your daily dose. This oil can also be combined with other cognitive enhancers without decreasing overall efficacy or experiencing adverse effects.
The benefits of krill oil can take several weeks to surface which is why it’s recommended that you take this supplement for at least 4-6 weeks before discontinuing use. Utilizing this oil is a great way to achieve balance between your health and the natural resources in which we have access to.
Nutrition and the dangers associated with various ingredients, has never been so confusing. One source will tell you that an ingredient is beneficial to your health, while another will steer you into a different direction. Fish and fish oils have been debated over the years, due to the exposure of metals and toxins within aquatic habitats.
When comparing regular fish oil, krill oil creates very few dangers. In fact, it provides your body and mind, with essential fatty acids. Since these fatty acids cannot be synthesized within the human body, it is crucial that you incorporate them into your diet.
Krill oil is known as an easy and effective way to gain essential fatty acids. When you consume enough omega-3 fatty acids, you promote brain health, while reducing age-related decay, and boosting your immune system.
In order to discuss the benefits and potential risks, we’ll focus on the physical and environmental concerns below. These concerns are generally brought up when discussing krill oil. We will also discuss why this supplement is important to your physical and mental health.
What Are the Dangers Associated with Krill Oil?
First, what exactly is krill? Krill is a small shrimp, which lives in cold, marine habitats. There is an abundance of krill in the Pacific, as well as in the Antarctic. Although we harvest around 110,000 tons of krill each year, this barely puts a dent in the total biomass of krill on earth.
It’s believed that there’s as much as 500 million tons of krill worldwide. When focusing on omega-3 fatty acids, krill is likely the most potent source for human consumption. If there’s an abundance and it is known to benefit our health, what’s the issue?
Well, fish and any other marine species, have raised concerns over the years. This is not due to marine species themselves, but their environment. Due to various factors, sea life is exposed to impurities, damage due to oxidation, and heavy metals. With that being said, krill is unique in terms of this exposure.
Is is widely believed, that krill has become resistant to such impurities and heavy metals. They are known to be resistant to oxidative decay, which is highly encouraging. Also, after krill is harvested, it is highly non-perishable (meaning, illness due to spoilage, is not typically a concern).
While focusing on the purity of any organic product, it is important to read about the manufacturer. In this case, farming practices can make a big difference in terms to what krill was exposed to. While focusing on side-effects, none are considered to be a true danger.
The most common side-effects are a fishy breathe and sweating. However, those that opt for red krill oil, tend to experience these effects less. Both fish and krill oil can cause an upset stomach in some of its users. As mentioned, none of these are true risks to your health.
What Shelf-Life Can I Expect From Krill Oil?
If you have experimented with fish oils, you know that some can decay rather quickly. Krill oil on the other hand, can last up to two years on your shelf. This is VERY important, because when oils decay, they can actually produce dangerous free-radicals.
Free-radicals are associated with a number of health concerns and diseases, which is why antioxidants are highly recommended within your diet (as they help fight off free-radicals in your body and brain). Age-related decay within your organs, is commonly associated with these free-radicals.
Due to krill oil’s extensive shelf-life, it is considered to be highly versatile in this sense. After it is harvested, it will still provide you with benefits months, or even years later. Users experience both physical and mental benefits when utilizing this oil.
How Does Krill Oil Work to Provide Health Benefits?
The key component of krill oil in which offers various benefits, is its omega-3 fatty acid content. More specifically, it is DHA and EFA which support your health. These are good fats, which benefit the health of your cell membranes. By making these membranes more permeable, you boost your immune response, as well as organ function.
While focusing on your brain, the blood-brain barrier plays a substantial role. Since these fatty acids can cross this barrier, they improve signalling between cells, as well as overall brain function. Krill oil contains high levels of phospholipids, which work as an antioxidant (targeting and fighting off free-radicals).
Krill oil helps to prevent decay and decreases your potential risk of degenerative conditions, such as Parkinson’s or Alzheimer’s. Within the phospholipids, there’s also high concentrations of choline. Not only is choline essential for synthesizing acetylcholine (a highly beneficial neurotransmitter for cognition), but is a vital nutrient for the human body. Due to its choline content, krill oil is a great supplement for mental health.
The Key Benefits of Krill Oil
As mentioned, krill oil provides numerous benefits when taken regularly. Since krill oils helps to improve your immunity and overall organ function, it is a highly recommended supplement. One of the key organs in which krill oil benefits, is the heart. Heart disease is a rising concern, affecting millions each year. It is important that we make heart-healthy decisions to encourage longevity.
If you suffer from a skin condition, krill oil can dramatically improve the look and feel of your skin. When taking krill oil, you can also reduce the signs of aging (decreasing the look of fine lines and wrinkles).
The brain is a key area of interest, as krill oil can help promote better memory and brain function. Symptoms of depression and anxiety have been reduced through krill oil consumption. Also, users have noticed benefits regarding stress management.
The Verdict: Is Krill Oil Dangerous?
The dangers associated with marine environments within krill oil, is not a serious concern. This is of course dependent on the ways in which the krill oil you choose, has been harvested, then packaged. As mentioned, know what you’re buying.
When taking krill oil on a daily basis, the positives outweigh any of the potential minor side-effects. With effects resulting in a stronger immune system, a more positive mental state, and greater organ support, you can see why krill oil is so highly recommended.
Benefits such as enhanced memory and concentration, are more than likely due to the high choline content found in this oil. If you have any questions or concerns, please do not hesitate to contact your healthcare professional.
Our brains require omega-3 fatty acids to function at an optimal level. We’re encouraged to consume more fish, but what supplements are available? When taking Antarctic krill, you can enhance your overall immunity, improve organ support, relieve symptoms of arthritis, improve your skin, lower cholesterol, and increase cognitive effects.
Which such an impressive list of benefits, it’s hard to ignore Antarctic krill oil. This tiny shrimp-like crustacean, is a staple food source across the globe. Due to the high levels of omega-3 found in krill oil, many individuals are incorporating this supplement into their dietary routine.
Krill populations prefer cold water oceans. Since there are different krill oil options, what are the key differences? Does the region affect the quality of this supplement? We’re going to focus on Antarctic krill, but Pacific krill provides the same benefits.
Is the Krill Population at Risk of Depletion?
Due to human use, global warming, and other related concerns; the depletion of natural resources are now being taken more seriously. These concerns are accurate when focusing on various fish and seafood populations, as we’re overfishing our beautiful oceans.
In terms of the krill industry, these concerns are diminished. There is less concern because krill represents a sustainable source of food. This is due to the volume of krill that’s found within our planet’s biomass. This is encouraging, as supplementation does not threaten the population as a whole.
At any given time, it’s estimated that approximately 500 million tons of krill are living in various oceans. Krill is a staple food in Asia and other areas, yet only around 110,000 tons are harvested each year. At the current rate of consumption, we will not make a substantial dent in the krill population.
These creatures are only 1 to 5 cm in length, yet they provide high sources of protein and omega-3 fatty acids. Both of these components are essential for proper human functioning. Omega-3 fatty acids need to be consumed within our diet, which is why krill oil is so beneficial.
What Are the Effects of Krill Oil?
As mentioned, krill oil provides us with essential omega-3 fatty acids. These fatty acids are carried to tissues of the brain at a cellular level. The beneficial acids, both EFA and DHA, penetrate cells and help increase the permeability of their membranes.
These fatty acids can generally be found in every single cell wall within our body. Unfortunately, we’re often deficient. This means that we do not have enough fatty acids to satisfy our needs. This is why more and more people are supplementing with krill oil and other related supplements.
When you take 1000 mg daily, you can help change cell membranes. This helps prevent rigidity. When cell membranes are less rigid, nutrients and waste travel more freely. In turn, cell function improves. Once your cells improve, you can increase the strength of your organs and maintain healthy tissue.
Krill Oil Provides You With Phosphatidylcholine
Krill oil contains a phospholipid known as phosphatidylcholine. This benefits your brain in two key ways. First, it creates anti-oxidants effect, protecting you from free radicals. Secondly, it helps elevate levels of choline in the brain.
Phospholipids help strength cells, which makes them less prone to damage. This is especially true in terms of oxidized particles, which are linked to age-related cognitive decline. Since choline encourages increased levels of acetylcholine, neuroprotective properties are enhanced.
Krill oil increases your brain’s ability to grow and change, improving overall neuroplasticity. This ensures that your brain cells are protected from damage, which improves communication throughout the brain. For these reasons, Antarctic krill oil is considered a beneficial brain food.
Is It Necessary to Take Antarctic Krill Oil?
Although not necessary, there have been hundreds of studies conducted, which report the benefits experienced through krill oil supplementation. When you consume ample amounts of Antarctic krill oil, you can increase your immune system, while strengthening your organs.
Your brain is not the only organ that benefits, as all major organs are positively affected. This is especially true for your heart, as it helps to reduce triglyceride levels and LDL cholesterol. Krill oil is also known to benefit your skin, making it less susceptible to the effects of aging.
When focusing on brain function, Antarctic krill oil boosts memory function, improves one’s ability to reason, and increases levels of concentration. Due to its effects on neuroprotective properties, this supplement can aid in the prevention of degenerative diseases such as Alzheimer’s.
Patients who suffer from Parkinson’s or Alzheimer’s, commonly take these supplements as part of their regular diet. This helps slow down the progression of their disease. For healthy individuals, Antarctic krill oil improves one’s ability to reduce stress.
Due to improved brain functionality, a better mood is also typically experienced. This is especially true for individuals that suffer from mild symptoms of depression or anxiety. For women, krill supplements have also been linked to reduced pain regarding PMS.
Is Antarctic Krill Oil Known For Any Serious Side-Effects?
When it comes to Antarctic krill, it’s exposed to pollution that we’ve created. Due to run-offs and dumping, our oceans are becoming polluted with toxins. This has resulted in heavy metal and toxin exposure within many species of fish and seafood.
When it comes to krill, they are at the bottom of the food chain. This means that they’re not exposed to high levels of toxic material, in comparison to fish and other species of marine life. From an environmental perspective, this means that krill is a ‘clean’ food source. Although many natural supplements do create slight side-effects, krill oil is known to be harmless regarding human consumption.
What Is the Recommended Dose of Antarctic Krill Oil?
The standard dose is between approximately 1000 and 2000 mg daily. There are different types of krill, but they do not differ much in terms of dosing and their efficiency. The key differences will be seen across various brands. Due to their preference for cold water, krill is most commonly harvested from the Pacific or Antarctic Ocean.
All krill has a red tone in terms of their color, which is why krill is often marketed as ‘red krill.’ This indicates the amount of algae in their diet, which is linked to a higher anti-oxidant effect. When deciding between krill from the Antarctic and Pacific, there’s very little difference. They both yield identical benefits. Look for the phospholipid content, as anything above 200-300 mg is considered an excellent product.
