Krill Oil Is Good For Your Heart
Studies have shown that krill oil can have a positive impact on our cardiovascular system and heart health. The Omega-3 fatty acids that occur in red krill oil, namely eicosapentaenoic acid and docosahexaenoic acid are considered to be healthy for the heart. They can improve blood lipid levels and studies show that krill oil might be particularly effective at lowering the levels of triglycerides and other blood fats. Other studies also showed that krill oil can raise good high-density-lipoprotein cholesterol and lower bad low-density-lipoprotein cholesterol.
But krill oil not only impacts the contents of our blood but also has an influence on our arteries. EPA and DHA can inhibit the development of artery clogging blood clots and the stiffening of the walls of blood vessels and therefore have a positive impact on our blood pressure and can contribute to reducing the risk of strokes and heart attacks.

A Cardiologist’s Top 10 Things To Know About Fish Oil Supplements
There’s more to consider about taking this common product than you may know.
Who knew that the decision to take a simple supplement like fish oil could be so complicated?
Omega-3 fatty acids may help decrease inflammation and decrease the risk of developing heart disease. At first, taking a supplement seems to be an easy decision. After all, why eat fish if you can get the active ingredients in a pill? Manufacturers tout the benefits relentlessly, but sometimes push so hard it seems as if they are trying to sell snake oil. Contrast that with studies suggesting that taking fish oil is worthless, or may cause harm. What does the evidence suggest? Here are some important things to consider:
Despite many studies done over the last few years, there is no absolute proof that taking omega-3 fatty acids will decrease your risk of having a heart attack. Studies are in progress to determine whether adding omega-3 fatty acids to a medical regimen including statins will lower your risk of a heart attack if you already have coronary artery disease.
DHA and EPA are the active ingredients in omega-3 fatty acids and have been shown in multiple studies to lower triglyceride levels. Triglycerides are a kind of fat, very different from cholesterol, that can cause irritation of the lining of blood vessels, especially when accompanied by low HDL cholesterol.

Polyunsaturated fats have more than one unsaturated carbon bond in the molecule and are found in plants and fish such as salmon. PUFAs also contain vitamin E and high levels of omega-3 and omega-6 fatty acidsnutrients essential for brain function and cell growth.
Some oils are high in omega-3 fatty acidshealthy fats that help to reduce inflammation and prevent the formation of arterial plaque. Avocado, canola, flaxseed, olive, peanut, sunflower, and walnut oils are all good sources of omega-3.

Krill Oil + Heart Health Study
Aker BioMarine sponsored a human study on krill oil, which investigated the effects of Superba KrillTM on blood lipids in subjects with borderline high or high triglyceride levels.
Three hundred subjects participated in this randomized, double-blind, placebo-controlled, multi-center U.S. study. The five treatment groups included a placebo group , as well as 4 groups taking 0.5, 1, 2 and 4 grams of krill oil daily.
Study results found that Superba Krill has the ability to lower triglycerides without raising LDL, the bad cholesterol in those who have borderline high or high triglyceride levels.
Superba Krills was also able to raise subjects Omega-3 Index levels, particularly among those taking the highest amounts.
It is interesting to point out that with the highest dose of krill oil, the omega-3 index increased by 70%. Even with the lowest dose of 500 mg krill oil, there was a significant increase. Thus, this might have an impact on the risk of sudden cardiac death, which has been demonstrated in several studies during the last decade, said Dr. Clemens Von Schacky, co-inventor of the HS Omega-3 Index Blood test.

Sensitivity Analysis And Publication Bias
The findings remained unchanged in the sensitivity analysis conducted on the triglycerides, LDL-C, and total cholesterol outcomes. However, when the data from the study by Bunea et al. were excluded from the sensitivity analysis for HDL-C, the I2 value for the studies comparing krill oil with fish oil and krill oil with other control supplements decreased to 0%, and the significant HDL-modifying effect of krill oil vs other controls disappeared . In several of the comparisons, publication bias was identified, as shown by a Luis Furuya-Kanamori index greater than2 or less than 2.
Reducing Inflammation And Cancer Risk
Your body converts absorbed omega-3 fatty acids in to eicosanoids, which are powerful hormones responsible for the release of anti-inflammatory prostaglandins throughout our bodies. Reduced inflammation helps to prevent many serious diseases and health complications.
Krill oil influences the actions of other hormones such as corticotropin-releasing hormones. When combined with increased levels of serotonin and dopamine, these help to elevate moods and can be beneficial in treating depression.
The EPA and DHA present in krill oil acts as a more-natural replacement for many anti-depressive medications and mood-enhancing drugs.
Finally, omega-3 fatty acid extracts from krill oil have been linked to the cessation of colorectal cancer cell growth. Because of the lack of side effects and because of the fact that krill oil is relatively well tolerated, it is being considered as a potential anti-cancer therapy and continues to be researched.
Krill oil can also help reduce the risk factors associated with diabetes, like insulin resistance and glucose levels. Regular intake of krill oil supplements can reduce blood glucose levels and improve glucose tolerance and insulin sensitivity.

How Is It Different From Fish Oil
In krill oil, 30-65% of the fatty acids are stored in the form of phospholipids, and krill oil also contains the antioxidant astaxanthin that gives it its red colour. This differs from fish oil, which is mainly made from fatty fish such as anchovies, salmon or mackerel and contains EPA and DHA mostly in the form of triglycerides. So while fish oil and krill oil share many of their health benefits, they differ in their origin and also have structural differences when it comes to their molecular makeup. This difference in molecular structure can affect the way that those fatty acids work and get absorbed in our bodies.
In fish oil, they mostly take the form of triglycerides which are a molecular structure combining three fatty acids such as EPA and DHA for example that are esterified to a glycerol backbone. In krill oil however, fatty acids take the form of phospholipids, which are among the most common fatty acids in our bodies and form the basis components of our cell membranes.
What Is Krill Oil Used For
Krill oil is often used for the same reasons as fish oil: to improve heart health and fight inflammation. Compared to fish oil, krill oil contains higher amounts of astaxanthina carotenoid pigment that gives krill and other crustaceans their characteristic red-pink color. Unlike many other antioxidant substances, preliminary studies have found that astaxanthin may cross the blood-brain barrier and protect the brain and central nervous system from free radical damage.
