Krill oil is a supplement that is rapidly gaining popularity as an alternative to fish oil. It is made from krill, a type of small crustacean consumed by whales, penguins and other sea creatures. Krill oil is high in important omega-3 fatty acids and has several potential health benefits. Here are some of the scientifically proven health benefits of krill oil:
Excellent source of healthy fats: Krill oil is an excellent source of omega-3 fatty acids, including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which are found only in marine sources. These fats have important functions in the body and are linked to a variety of health benefits .
Can help fight inflammation: Omega-3 fatty acids like those found in krill oil have been shown to have important anti-inflammatory functions in the body. Krill oil may be even more effective at fighting inflammation than other marine omega-3 sources because it appears to be easier for the body to use. Krill oil also contains a pink-orange pigment called astaxanthin, which has anti-inflammatory and antioxidant effects .
May improve heart health: Krill oil may help improve several risk factors for heart disease, including high blood pressure, high levels of triglycerides, and low levels of HDL cholesterol. Krill oil may also help reduce inflammation, which is a key factor in the development of heart disease.
May help reduce PMS symptoms: Krill oil may help reduce the severity of premenstrual syndrome (PMS) symptoms, such as cramps, bloating, and mood swings. One study found that women who took krill oil supplements for three months experienced a significant reduction in PMS symptoms compared to those who took a placebo .
May help improve brain function: Krill oil may help improve brain function and reduce the risk of age-related cognitive decline. One study found that krill oil supplements improved working memory and reaction time in healthy young adults .
