Did you know that there’s a tiny sea creature that packs a powerful punch when it comes to your health? Enter krill oil, a supplement derived from small, shrimp-like crustaceans known as krill. In recent years, this oil has gained popularity for its numerous health benefits, making it a must-have
for anyone looking to unlock their full potential.
Krill oil is rich in omega-3 fatty acids, specifically EPA and DHA, which are crucial for brain health,
heart function, and inflammation reduction. Not only does it provide these essential nutrients, but it
also contains astaxanthin, a potent antioxidant that supports overall well-being. Incorporating krill oil
into your daily has been found to:
- Promote cardiovascular health
- Assist in managing inflammation
- Boost cognitive function
- Alleviate joint pain
- Improve skin health
With its unique composition and superior absorption, krill oil offers a highly effective alternative to
traditional fish oils.
What Is Krill Oil, and How Is It Different from Fish Oil?
Krill oil is a dietary supplement derived from tiny, shrimp-like crustaceans known as krill. These
small yet mighty creatures thrive in the cold, nutrient-rich waters of the Antarctic and Arctic regions. Unlike traditional fish oil, which is extracted from larger fish species, krill oil is sourced from these miniature marine organisms.
Krill oil is a multi-nutrient powerhouse, naturally rich in high-quality omega-3s (EPA and
DHA), choline, and astaxanthin. The true benefit of krill oil lies in its phospholipid structure, which allows the body to recognize and absorb these vital nutrients in the most efficient way.
Phospholipids, often referred to as “molecules of life,” are essential components of cell membranes,
playing a crucial role in maintaining cellular structure and function. Krill oil phospholipids deliver omega-3 fatty acids and choline directly to cell membranes, promoting cellular health. These nutrients are then distributed throughout the body, supporting the organs and tissues.
Since cellular health is foundational to overall health, krill oil’s impact at the cellular level is vital for maintaining a healthy body.
Furthermore, krill oil naturally contains the powerful antioxidant astaxanthin, which is not typically
present in fish oil supplements. Astaxanthin helps to protect the omega-3 fatty acids from oxidation,
ensuring their stability and potency. This unique combination of omega-3s and antioxidants makes krill oil a highly effective and versatile supplement for supporting overall health and well-being.
Krill oil is also a great source of choline, which we now know is just as important as omega-3s for human health. A recent study has been published, measuring the uptake of choline in the body after
supplementation with krill oil. This study, which was performed as a randomized, placebo-controlled,
monocentric, two-way cross-over pharmacokinetic study, shows that krill oil significantly increases plasma choline levels in the body.
However, unlike other choline supplements, krill oil does not raise levels of TMAO (trimethylamine
N-oxide). High levels of TMAO can lead to a number of health issues, when combined with other many
dietary/lifestyle factors. What’s more, choline occurs naturally in krill oil, in the form of phosphatidylcholine (PC), which has been demonstrated to be more effective in raising choline levels in the blood than choline salts. Other choline supplements such as choline salts, do not occur naturally and are created in a lab.
Krill Oil for Heart Health
Cardiovascular health is one of the primary areas where krill oil has demonstrated its remarkable benefits. The omega-3 fatty acids found in krill oil, specifically EPA and DHA, have been extensively studied for their ability to support a healthy heart.
One of the keyways krill oil supports heart health is assisting in managing blood pressure. “Research
shows that omega-3 fatty acids, which are found in krill oil, may decrease blood pressure in some individuals and might have a modest effect of lowering blood pressure,” says Registered dietitian Mira Ilic, RD. Furthermore, the omega-3s in krill oil have been shown to help reduce inflammation, contributing to many cardiovascular conditions. By addressing inflammation, krill oil can help maintain healthy blood pressure levels and reduce the risk of heart attacks and strokes.
Krill Oil Helps Manage Frailty
Although the underlying causes of frailty are complex, evidence indicates that nutrition should be considered a modifiable environmental factor that may prevent or reduce the risk of frailty. Chronic low-level inflammation is one of the pathophysiological processes involved in frailty that can be impacted by diet.
Researchers have reported that frailty is associated with high levels of inflammatory markers, such
as C-reactive protein (CRP) and interleukin (IL)-6, and that levels of IL-6 are even more closely linked to frailty than age is. Omega-3 fatty acids could affect frailty outcomes by influencing inflammatory processes. Increasing the intake of omega-3s in the diet increases the content of omega-3s in cellular
membranes. According to William S. Harris, founder of the Fatty Acid Research Institute, “a low Omega-3 Index was associated with increased frailty,” He also indicated that “There is a need for elderly people to maintain a high Omega-3 Index to reduce their risk for becoming frail.”
One way inflammation impacts frailty is through its effects on muscle mass. Sarcopenia, defined as the loss of skeletal muscle mass and function, is also associated with increased inflammation, which omega-3s can help resolve. Furthermore, growing evidence indicates that omega-3s may help retain muscle mass and function by mechanisms beyond inflammation control, such as increased nerve
conduction and muscle activation, improved mitochondrial function, and increased muscle protein synthesis. Supporting the maintenance of muscle tissue through adequate omega-3 intake could potentially improve several frailty criteria.
Krill Oil for Brain Health and Cognitive Function
The omega-3 fatty acids found in krill oil, particularly DHA and EPA, are crucial in supporting brain
health and cognitive function. These essential nutrients are vital for developing and maintaining the brain, and they have been linked to a wide range of cognitive benefits.
One of the keyways in which krill oil supports brain health is by promoting neuronal function and
protecting the brain from age-related decline. Studies have shown that the omega-3s in krill oil can help improve memory, enhance focus and concentration, and reduce the risk of cognitive impairment and dementia.
A recent study suggested that providing extra dietary omega-3 DHA might slow the development
of dementia. Such a cost-effective, low-risk dietary intervention like this could potentially save billions in health care costs according to William S. Harris.
Beyond its cognitive benefits, krill oil has also been found to support emotional well-being and mental
health. The omega-3s in krill oil have been linked to reduced symptoms of depression and anxiety, as well as improved mood regulation. By addressing both the physical and emotional aspects of brain health, krill oil can help you achieve a greater overall well-being.
Krill Oil for Joint Health and Inflammation
Krill oil works at the cellular level, helping to combat oxidative stress, modulate inflammation, as well
as reduce symptoms of joint pain and discomfort. Krill oil’s naturally occurring choline is beneficial for
muscle function and health; healthy muscles are vital for supporting and protecting our joints. And in addition to these health benefits, krill oil increases the Omega-3 Index, which supports overall health and may reduce the risk of various chronic conditions.
A breakthrough study (representing the largest and longest study with krill oil) showed positive effects of krill oil for adults suffering from mild to moderate knee osteoarthritis (OA). Key results from the krill oil group include improvements in knee pain, as well as knee stiffness and physical function. The Omega-3 Index level increased in the krill oil group from 6.0% at baseline to 8.9% at three months and 9.0% at six months. Participants with the greatest level of inflammation at the start of the study were the ones that had the biggest pain improvement. The study was conducted by the H&H Research team of Swisse, along with CSIRO, Australia’s national science agency, across three clinical trial sites in
Australia.
It’s important to look at joint health from a preventative care point of view. When you are young, developing good habits early can protect your body as you get older, and as you age, the focus shifts to maintaining your health or ‘healthspan’, especially for seniors who need consistent, daily support. Keeping your body healthy is a lifelong journey, and krill oil helps to support joint health at various ages and stages of life, along with diet, exercise and other healthy habits.
Krill Oil for Skin Health and Anti-aging
As we age, the skin’s ability to produce key molecules like hyaluronic acid and collagen declines, leading to dehydration, wrinkles, and a loss of elasticity. This makes nutrients that support skin health at a cellular level all the more important.
Superba Boost® (an ingredient that powers many of the best-known krill oil brands) is a natural extract packed with bioactive nutrients that nourish the skin from the inside out, helping to restore hydration and maintain a youthful appearance. It contains marine phospholipid omega-3s, choline, and the potent antioxidant astaxanthin, which work together to promote the production of ceramides, collagen, and hyaluronic acid—critical elements for reducing wrinkles and achieving radiant, glowing skin* (as shown in both in vitro and in vivo studies). These compounds also support the skin’s hydration, elasticity, and protection from environmental stressors and aging. In combination, they offer a comprehensive approach to enhancing skin health and appearance.
Clinically proven to strengthen the skin’s barrier, Superba Boost helps prevent water loss, boosts
moisture retention, and improves skin elasticity** (as demonstrated in human clinical studies). The result is healthier, more resilient skin that retains its youthful look for longer.
Two recent studies published in the Journal of Cosmetic Dermatology examined the effects of krill oil
supplementation on skin barrier function. These studies found that daily oral intake of Superba Boost
Krill oil (1 and 2 grams) significantly improved skin barrier strength, hydration, and elasticity compared to a placebo group. Furthermore, improvements in these skin qualities were correlated with an increase in the Omega-3 Index in red blood cells, underscoring the link between omega-3 fatty acids and skin health.
Choosing the Right Krill Oil Supplement
When selecting a krill oil supplement, it’s essential to choose a high-quality product that meets specific standards to ensure you’re getting the maximum benefits.
One of the critical factors to consider is the source of the krill. Look for a supplement sourced from the pristine waters of the Antarctic or Arctic regions, where krill populations are sustainably harvested. This ensures the krill oil is free from contaminants and provides the optimal nutritional profile.
Additionally, pay attention to omega-3 fatty acids and astaxanthin concentration in the krill oil
supplement. Reputable brands will indicate the amounts of EPA, DHA, and astaxanthin present in their products, allowing you to make an informed decision.
Krill oil is a premium ingredient, and a good quality krill oil is defined by its high content and concentration of phospholipids. High phospholipid content means superior and genuine quality krill oil in its natural form; krill oil is not diluted with other oils or soybean phospholipids.
It’s also important to consider the purity and quality of the krill oil. Look for a supplement that has been third-party tested for purity and potency, ensuring that it is free from any harmful substances or impurities.
Finally, consider the bioavailability of the krill oil supplement. As mentioned earlier, the unique
phospholipid structure of krill oil allows the body to enhance absorption and utilization. This can make a significant difference in the overall effectiveness of the supplement.
In conclusion, krill oil is a remarkable supplement that offers many health benefits, from supporting cardiovascular health to promoting brain function and cognitive performance.
