How to Improve Your Cholesterol with Krill Oil

How to Improve Your Cholesterol with Krill Oil

Cholesterol levels can be a deciding factor when it comes to maintaining a healthy heart. Cardiovascular diseases have become a global health challenge, due in part to changing diets and more fast food, which makes managing cholesterol all the more important.


One natural remedy that’s reshaping the health food industry is krill oil. It’s a breakthrough that’s both new and rooted in ancient traditions, and Krill USA is leading the way in bringing the benefits of Antarctic krill meat, and particularly krill oil, to people all over the world. 

What Is Cholesterol?

Cholesterol is a waxy, fat-like substance that’s found in every cell of the body. It isn't a bad thing in moderation: in fact, it's essential for the synthesis of vitamin D, hormones, and substances that aid in food digestion. While our body produces all the cholesterol it needs, it's also obtained from animal-based foods. This cholesterol travels in the bloodstream in tiny bubbles called lipoproteins, which consist of lipids (fats) on the inside and proteins on the outside.

How to Measure Total Cholesterol?

Total cholesterol is measured through a blood test called a lipid panel or lipid profile. It’s used to calculate the levels of three different but related forms of fat in the bloodstream:


  • LDL (low-density lipoprotein) cholesterol: Often described as the “bad” cholesterol, high levels of LDL can lead to cholesterol buildup and blocked arteries.
  • HDL (high-density lipoprotein) cholesterol: Known as the “good” cholesterol, it helps remove LDL cholesterol from arteries by carrying it back to the liver.
  • Triglycerides: This form of fat typically comes from a high-calorie diet, and a high triglyceride level can harden arteries and increase the risk of heart disease.

What Is Krill Oil?

Krill oil is derived from krill, which are tiny, shrimplike crustaceans that are predominantly found in the cold waters of the Antarctic. These creatures play a vital role in the marine ecosystem, serving as food for larger marine animals like whales and seals. Krill meat has also been a part of the traditional diet of certain seafaring cultures, such as Japan, for millennia.


Beyond their ecological role, krill have become increasingly popular in recent years for their oil, which is rich in omega-3 fatty acids and astaxanthin but low in LDL cholesterol.

What Are Omega-3 Fatty Acids?

Omega-3 fatty acids are essential fats that our bodies cannot produce on their own. Predominantly found in marine sources, including krill oil, and in certain plant-based foods, these fatty acids play a pivotal role in various physiological processes.


Some of the key benefits and roles of omega-3 fatty acids include:


  • Brain Health: Omega-3s are crucial for brain function and memory processing.
  • Anti-Inflammatory Properties: They also reduce inflammation throughout the body, which can otherwise result in numerous chronic health conditions.
  • Heart Health: Regular intake of Omega-3 fatty acids can lower blood pressure, and decrease the risk of heart disease while regulating cholesterol levels.
  • Mental Health Support: Omega-3s can positively impact mental health by reducing the symptoms of depression, ADHD, and related psychological conditions.
  • Support During Growth: Their intake is vital during the developmental stages, promoting healthy growth and development in both infants and children.

Omega-3 fatty acids are an essential part of any balanced diet.

What Is Astaxanthin?

Astaxanthin is a particularly powerful antioxidant that’s found in krill oil as well as several other marine sources. It's responsible for the reddish-pink color of krill, salmon, and other seafood. Beyond its vibrant hue, astaxanthin boasts a range of health benefits.


Some of the notable benefits of astaxanthin include:


  • Potent Antioxidant Properties: Astaxanthin is known to be one of the most powerful antioxidants in nature, helping combat free radicals in the body.
  • Skin Health: It can protect the skin from harmful UV radiation and reduce signs of aging.
  • Eye Health: Astaxanthin has been linked to improved eye health, potentially reducing the risk of developing cataracts and the onset of macular degeneration.
  • Anti-Inflammatory Effects: Like Omega-3 fatty acids, astaxanthin can help reduce inflammation that’s otherwise associated with various chronic diseases.
  • Improved Athletic Performance: Some studies suggest that astaxanthin can even boost endurance and reduce muscle damage during a workout routine.

With its myriad of health benefits, astaxanthin stands out as a super-antioxidant, making it a valuable component of krill oil and a beneficial supplement for overall well-being.

What Are the Benefits of Krill Oil?

Krill oil has emerged as a highly sought-after supplement in the health and wellness community. Its rich content of omega-3 fatty acids, astaxanthin, and phospholipids helps set it apart from other marine oils. These components work synergistically, offering many different benefits ranging from supporting cardiovascular health to enhancing cognitive functions. 

Balancing Good and Bad Cholesterol

Cholesterol management involves the careful balance of LDL (bad) and HDL (good) cholesterol. Krill oil plays a pivotal role in maintaining this balance. Its omega-3 content has shown promise in reducing LDL cholesterol levels while simultaneously increasing HDL levels. 


By fostering a healthier cholesterol balance in the body, krill oil aids in promoting cardiovascular health and reducing the long-term risk of many different heart-related ailments.

Reducing Inflammation

Inflammation, when chronic, can be the precursor to a host of diseases. Krill oil, rich in omega-3 fatty acids, acts as a potent anti-inflammatory agent. By mitigating inflammation, krill oil not only supports joint and muscle health but also plays a role in combating conditions where inflammation is a primary concern, such as arthritis and cardiovascular disease.

Enhancing Absorption

One of the standout features of krill oil is its high bioavailability. Thanks to the phospholipids present in krill oil, the body can absorb its nutrients more efficiently compared to other sources of omega-3. This enhanced absorption ensures that individuals get the maximum benefits from every dose, making krill oil a preferred choice when it comes to omega-3 supplements.

What Are the Downsides of Krill Oil?

Krill oil, like any substance, is not without its potential drawbacks. While it offers a wide range of health benefits, it's essential to be aware of its potential downsides as well:

Cost Implications

Krill oil supplements can be more expensive than other sources of omega-3s, such as fish oil. This cost difference can be attributed to the sustainable harvesting methods and the processing required to extract oil from krill. For some, this price point might be prohibitive.

Digestive Discomfort

Some users have reported digestive issues after consuming krill oil. Common complaints include stomach discomfort, diarrhea, and a fishy aftertaste or burp. While these side effects are not universal, they can be off-putting for individuals who are sensitive to krill oil.

Limited Research

While preliminary research on krill oil is promising, it's worth noting that it hasn't been studied as extensively as other omega-3 sources, like fish oil supplements. As a result, some of its benefits are based on anecdotal evidence rather than more rigorous scientific studies.

Environmental Concerns

The increasing demand for krill oil raises concerns about the sustainability of krill harvesting. Overfishing can disrupt the marine ecosystem, impacting the larger marine animals that rely on krill as a primary food source. While there are sustainable krill fishing practices, not all manufacturers adhere to them, leading to potential ecological imbalances.


Krill USA cares about sustainability and protecting the environment, as well as the animals that rely on krill to survive, from blue whales to seals and penguins. We work to ensure that our krill meat comes from a managed krill fishery that won't impact the Antarctic ecosystem. If you'd like to enjoy the health benefits of krill oil without risking the side effects of a concentrated dose, you can also find it as a natural ingredient in our Antarctic Krill Meat in Water.

Who Should Avoid Krill Oil?

While krill oil has garnered praise for its myriad health benefits, there’s not a one-size-fits-all remedy in medicine. Like many supplements, krill oil may interact differently with individuals based on their unique health profiles, medications, and other individual factors.


It's essential to approach its consumption with an informed perspective, understanding potential concerns and risk factors. Here are a few specific scenarios and groups of individuals who might need to exercise caution or consider healthy alternatives to krill oil.
