Fish oil is one of the most popular dietary supplements in the world and is derived from fatty fish like salmon, mackerel, and anchovies. There is no need to pinpoint the health benefits of fish oil, as probably you all are familiar with it.
Its health benefits majorly come from two kinds of omega-3 fatty acids-
- eicosapentaenoic acid (EPA)
- docosahexaenoic acid (DHA)
Their benefits have been highly publicized. They both have shown to improve brain and heart health, among other benefits.
Our body isn’t capable of making omega-3s on its own, so including fish oil in our diet is essential.
However, lately a supplement known as krill oil has appeared as another DHA and EPA-rich product. Many health food experts even state that krill oil offers more health benefits than fish oil. And Krill Oil in Canada can be best found at Yes Wellness.
In this Krill Oil vs. Fish Oil blog post, we will examine the differences between them and evaluate the evidence to determine which one is better for your health.
What is Krill Oil?
Most of the people are familiar with fish oil but only fewer of us know about Krill oil supplements.
Krill oil is harvested from little crustaceans called Antarctic Krill. These marine creatures are a dietary staple for many sea animals including seals, whales, penguins, and birds.
Krill oil, similar to fish oil is a high source of DHA and EPA omega-3s – the fatty acids that provide most its health benefits. However, the two types of omega-3 acids in krill oil are anatomically different from those in fish oil and this may influence the way our body uses them.
In terms of appearance, krill oil looks different from fish oil. While fish oil boasts a shade of yellow, astaxanthin, a naturally occurring antioxidant gives krill oil its reddish shade.
Krill Oil is more Bioactive – Our Body May be Able to Absorb it Better
Both krill oil and fish oil are excellent providers of omega-3 fatty acids. However, some studies suggest that human body may use and absorb the omega-3 fatty acids in krill oil better than those in fish oil.
The omega-3s in krill oil are called phospholipids, and, much of the omega-3s in fish oil are triglycerides, which the experts believe decreases their absorption and effectiveness.
In an experiment, a group of participants was given either krill or fish oil over the next several days. During that period, levels of fatty acids in their blood were measured.
Over three days, blood concentrations of DHA and EPA were higher in those participants who took krill oil. The experiment concluded that the participants absorbed krill oil better than the fish oil.
In another study, the participants were given either fish oil or about two-thirds of the same quantity of krill oil. The result showed that both treatments elevated the blood levels of DHA and EPA by the same amount, even though the krill oil dosage was lower.
Though, many experts have reviewed the theory but say that there is no adequate evidence to prove that krill oil is more bioactive and is absorbed readily than fish oil.
Krill Oil is a Rich Source of Antioxidants
Antioxidants are known to protect our body from oxidative stress caused by free radicals – a molecule that triggers cell damage.
Krill oil is rich in astaxanthin – an antioxidant that is not found in most fish oil.
Health food experts claim that astaxanthin protects krill oil from oxidation and prevents it from going fetid on the shelf. Well, for now, there is no definitive proof or research that supports or confirms this claim.
But studies have confirmed that astaxanthin and krill oil’s anti-inflammatory properties may provide some cardiovascular health benefits.
A study demonstrated that secluded astaxanthin reduced the levels of triglycerides and elevated ‘good’ HDL cholesterol in individuals with slightly increased phosphatides in blood.
Though, this study provided astaxanthin in much larger quantity than those you would usually get from krill oil supplements. It is still not clear whether smaller doses would provide the same benefits.
Krill Oil May Improve Cardiovascular Health than Fish Oil
Fish oil is known for its useful effects on cardiovascular health, but numerous studies have shown that krill oil also offers the same benefits when it comes to heart health. Krill oil was said to reduce the blood sugar levels, ‘bad’ cholesterol, and triglycerides in the body even when it was given at lower doses.
Fish Oil is Easily Accessible and Cheaper
One advantage fish oil has over krill oil is that fish oil is typically more accessible and much cheaper.
Although krill oil shares or even exceeds many of the fish oil’s benefits, it comes at a higher cost. This is due to the expensive processing and harvesting methods. And a good quality Krill oil in Canada may cost up to ten times the cost of fish oil.
So should you take fish oil or krill oil? Overall, both the supplements are a great source of omega-3s and there is plenty of research that backs their health benefits. However, the evidence demonstrates that krill oil may be more effective in improving several risk factors of cardiovascular diseases.
But due to lack of research and extreme price differences, it may be in your best interest to go with fish oil.
