Krill oil phospholipids may reduce the risk of cardiovascular disease

Omega-3 Phospholipids heart health Omega-3 Benefits

9 min. read


Cardiovascular disease is the global leading cause of death, accounting for more than 18.6 million deaths in 2019 worldwide. Along with being the leading cause of death, heart disease and stroke are major causes of disability and soaring health costs around the world.


There are over 520 million people globally living with cardiovascular disease, making it one of the most important and relevant threats on our health and our healthcare systems.

The good news is that it is almost entirely preventable.


Maintain a healthy heart throughout life

Our heart is arguably our body’s most important muscle, working continuously, from the moment it starts for the duration of your lifetime. The main function of the heart is to pump oxygenated blood, along with hormones and other vital nutrients, around the body from head to toe through a network of blood vessels like arteries and veins. 


One might say the heart is the powerhouse to your whole body, and it is therefore important to give the heart what it needs and to create an environment where it can thrive! There are many things you can do regularly to support your heart:


Eat a healthy diet.

Limiting alcohol, smoking and other habits that are detrimental to health. Eating a varied diet including lots of nutritious foods like fruits, vegetables, whole grains and healthy fats sources like nuts, seeds, avocados and fish.



Like all our muscles, our heart loves to be trained. Raising your heart rate several times a week during moderate exercise helps to keep the heart strong, working properly and in good shape for a long and healthy life.



It can be smart to be proactive about your heart health and this is where supplementation can really make a difference. A recently published meta-analysis of studies concluded that omega-3 fatty acid (EPA and DHA) intake reduced cardiovascular mortality and improved cardiovascular outcomes. 


Krill oil omega-3 phospholipids have heart health benefits

Krill oil phospholipid is a supplement obtained from Antarctic Krill containing omega-3 fatty acids (EPA & DHA), choline and phospholipids, three nutrients that help support the functioning of a healthy heart.

Krill oil has been extensively studied for a wide range of health benefits, and due to the naturally occurring choline and omega-3 levels in krill oil, it is most widely known for its heart health promoting properties. 


Krill oil has been shown in several published clinical trials to improve 3 markers of heart health associated with cardiovascular disease, and an updated review and meta-analysis on the clinical effectiveness of krill oil supplementation and cardiovascular health proved to be consistent and positive. 14 trials with 1458 participants showed that krill oil supplementation had beneficial effects on total cholesterol, low density lipoprotein cholesterol and triglycerides. These promising results, published in Diabetes and Metabolic Syndrome: Clinical Research and Reviews (an influential journal with an impact factor of 10 in 2022) further validate the amazing potential for krill oil and heart health.


1. Krill oil raises the Omega-3 Index level in your body

Krill oil has been shown in several studies to significantly raise the levels of omega-3 fatty acids, specifically EPA and DHA, in red blood cell membranes. An Omega-3 Index of 8% or above is the optimal range, widely demonstrated to be optimal for healthy heart function. Raising your blood levels of these much-needed omega-3 fatty acids is vital, and unfortunately, the majority of the world’s population is below this level due to lack of omega-3 EPA and DHA sources in the diet, like oily fish. This is where supplementation is a smart option.

Krill oil significantly raises your Omega-3 Index levels in just 30 days. 


2. Studies show krill oil may be beneficial for your cholesterol levels

It is well established that high levels of circulating cholesterol can be detrimental for our heart health. A double-blind, randomized, prospective study by Bunea et al. found a significant reduction in LDL “bad” cholesterol and an increase in HDL “good” cholesterol after 12 weeks of krill oil supplementation. A 2016 double-blind, randomized clinical trial showed that krill oil significantly raised HDL “good” cholesterol levels further confirming the beneficial effect.


3. Studies show krill oil may be beneficial for your triglycerides levels

High levels of fasting triglycerides in the blood plasma are associated with an increased risk for cardiovascular disease and problem with the body’s heart systems. This is often a measure that is used by general practitioners to give an indication of the health of the cardiovascular system.


In 2022, a major double blind, randomized, placebo-controlled trial with over 500 participants published in JAMA Network Open, which showed that krill oil significantly reduced fasting triglycerides by 33.5% from baseline after 26 weeks (placebo corrected 12.7%). Read more about the study.


This study builds on previous studies that show similar effects such as Berge et al in 2014 showed that krill oil significantly reduced fasting triglycerides over a period of 12 weeks. 


Krill oil contains heart healthy omega-3s and choline to help support your heart with several studies documenting the benefits of supplementation on several markers of cardiovascular disease.



New call-to-action


Consumers are more invested in taking proactive measures to protect their heart than ever before

According to Wholefoods Magazine and their Heart Health Update 2023, consumers are more invested in taking proactive measures to protect their heart than ever before. New factors playing a role in increasing consumer awareness and emphasis on heart health are attributed to Covid, prompting consumers to focus more on their general health and well-being as well as their heart health.


Indeed, a 2022 Cleveland Clinic survey found that 41% of Americans experienced at least one heart-related health issue, including shortness of breath, high blood pressure, and chest pain, since early 2020.


Also, a shift in interest in heart health across demographics has been observed in the dietary supplement industry.  In the past, heart health was closely associated with healthy aging, and older consumers were seen as the most important target market. Now, it’s increasingly likely to be connected with areas like sports, performance and energy, and with a younger demographic.


Approved heart health claims around the world

Omega-3 (EPA & DHA) and choline in krill oil have together 3 approved EU Approved Health Claims for heart health. Furthermore, the FDA in the USA has approved a heart health claim for EPA & DHA which further demonstrates the confidence in the science that omega-3 fatty acids and choline are beneficial for our heart health.
