Isn’t fish oil just as good?

Those who support fish oil say that their product has proven benefits, with thousands of studies to back up its health benefits, and krill oil is still relatively new.

Australians have certainly taken to fish oil supplements, with sales increasing by a whopping 65 percent just in the past seven years.

There is plenty of room in the market for both types of omega-3s: It’s simply a matter of choice and price, according to most researchers. The important thing is to get in your recommended dose of omega-3s from whatever source appeals to you and your pocketbook.

It’s true that there are not nearly as many studies involving krill oil as there are fish oil supplements, but here are a few of the studies that we found:

  • Heart health. It is well known that the consumption of omega-3s found in fatty fish or fish oil pill can reduce heart attack risks. A study published in the 2011 issue of the journal Lipids found that you can get the same benefits of fish oil for your heart by taking krill oil supplements. This study involved 113 male and female subjects who underwent testing during a7 week clinical trial. These tests have shown that the blood levels of EPA and DHA got higher just as much in both the fish oil group and the krill oil group when compared to the placebo group. This doesn’t mean that krill oil or fish oil was “better,” but only that both oils were equally beneficial to the body.
  • PMS. Studies have shown that krill oil supplements reduced pain and other PMS symptoms much better than fish oil. This study, reported in Alternative Medicine Review issued in May 2003, found that krill oil supplements were more effective in managing self-reported joint pain, mood swings, and breast tenderness,. There did not appear to be any difference between the two supplements when it came to swelling, abdominal pain, bloating, or weight gain.
  • Arthritis. Krill oil did seem superior for those who suffer from arthritis by reducing inflammation, pain, and stiffness — that is, according to the clinical trial carried out at the University Health Network in Toronto, Canada. In this study, krill oil was found to reduce pain much better than a placebo and CRP levels fell a whopping 31 percent among those taking the krill oil when compared to the 25 percent rise in the placebo group.

Although there are benefits in both supplements, it does appear that there is a slight edge to krill oil, according to the research we were able to find.
