Heart diseases are the leading cause of death worldwide. These diseases include atherosclerosis, hypertension, and arrhythmias.

High cholesterol levels, lack of physical activity, and unhealthy diet contribute to the development of cardiovascular diseases. Krill oil supplements have gained popularity in recent years due to their ability to improve heart health. Krill oil is extracted from small crustaceans and is a rich source of omega-3 fatty acids, phospholipids, and antioxidants.

This article will discuss how krill oil supplement improves cardiovascular health.

What is Cardiovascular Health?

Cardiovascular health encompasses the health of the heart and blood vessels. These two components work together to deliver oxygenated blood to the body’s tissues and remove carbon dioxide.

Good cardiovascular health results in efficient circulation, ensuring that every organ receives enough oxygen and nutrients. Poor cardiovascular health, on the other hand, can lead to heart attack, stroke, and other life-threatening conditions.

How Krill Oil Improves Cardiovascular Health?

Krill oil is a source of essential omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids reduce inflammation and improve lipid metabolism.

Reduces Inflammation

Inflammation is a response to infection, injury, or stress. Chronic inflammation is associated with the development of atherosclerosis, a condition where plaque builds up in the arteries.

This plaque causes narrowing and hardening of arteries, leading to reduced blood flow and increased risk of heart attack and stroke. EPA and DHA in krill oil have anti-inflammatory properties and can reduce the risk of atherosclerosis.

Improves Lipid Metabolism

High levels of low-density lipoprotein (LDL) or bad cholesterol and low levels of high-density lipoprotein (HDL) or good cholesterol are risk factors for heart diseases. Krill oil can reduce LDL cholesterol levels and increase HDL cholesterol levels.

A study conducted on adults with high cholesterol levels showed a significant reduction in LDL cholesterol levels after taking krill oil supplements for eight weeks. DHA in krill oil can also prevent the formation of abnormal blood clots, reducing the risk of heart attack.

Reduces Blood Pressure

Hypertension or high blood pressure is a significant risk factor for heart diseases. Krill oil supplements can reduce blood pressure in people with hypertension.

EPA and DHA in krill oil have vasodilatory properties, meaning they can widen the blood vessels and improve blood flow. A study conducted on overweight and obese adults showed a significant reduction in blood pressure after taking krill oil supplements for three months.

Protects Heart from Damage

Krill oil is a rich source of antioxidants, including astaxanthin. Antioxidants can neutralize free radicals, reducing oxidative stress and preventing damage to the heart and blood vessels.

Astaxanthin, in particular, is shown to improve lipid metabolism and reduce inflammation, further improving cardiovascular health.

Conclusion

Krill oil supplements are shown to improve cardiovascular health in a variety of ways, including reducing inflammation, improving lipid metabolism, reducing blood pressure, and protecting the heart from damage.

Krill oil is a safe and effective way to support heart health. However, as with any supplement, it is essential to consult with a healthcare provider before starting to take krill oil supplements.
