Medical Forum / General / Nutrition / January 2007*research* on fish oil burps and oxidation?
I've frequently seen a claim (often in advetising materials for Nordic Naturals) that if your fish oil capsules cause fish-flavored burps, that means they are oxidized and potentially unhealthy. I have not been able to find substantiation for this on the web, in medical journals, or from the Nordic Naturals people themselves. Does anyone know of any research that addresses the topic?

I don't, but the burps are just that, burps. They should taste fishy, just not like old, rotten fish. I think I heard a pop book doc on TV yesterday say that if you keep the caps in the freezer, you won't get the fishy burps.

It is not limited to fish oils. My daughter inlaw took DHA supplement derived from ocean algae during her pregnancy. Her major complaint was burping. The burping is lessened if you take the supplement just before eating. It is true that if the supplements were stored at high room temperature for a long time, the oil may become oxidated and rancid. The supplements should be stored in the refrigerator to prevent them from getting rancid. If the supplements have become rancid they should be thrown away. Rancid supplement burps will be more fishy. Burping eventually lessens as your body gets used to the enzymes. In case of my daughter inlaw burping disappeared after the first trimester. Either her body got used to the enzymes or it may have something to do with the pregnancy itself, I cannot say. > > I've frequently seen a claim (often in advetising materials for Nordic > > Naturals) that if your fish oil capsules cause fish-flavored burps, [quoted text clipped - 22 lines] > enzymes or it may have something to do with the pregnancy itself, I > cannot say. I don't know if it's true, but I've heard that your body needs fish oil to properly digest fish oil. Something like that. And, so, the more fish oil you eat, the better you become at digesting it. If true, that may also suggest that the more burping one experiences, the more they really should be taking it. I made that up. When I first started taking fish oil, I had lots of annoying fish-burps and it bothered me. That may have lasted a couple months, I don't remember exactly. Now, it's been years and I NEVER have any burps. None. Something pretty fundamental must have changed, because it's not just less burps, it's never. And, I take 12 Kirkland fish oil concentrate capsules per day. Six in the morning and six at night. You might want to try pharmaceutical grade fish oil concentrate liquid: http://www.iherb.com/store/ProductDetails.aspx?c=Herbs&pid=NFS-03574 It has 1500mg EPA per teaspoon (not tablespoon). The EPA and DHA are so concentrated, there can't be much "fish" left. I would like to use it (so I didn't have to swallow 12 caps), but it's still a little more expensive per mg EPA than Kirkland. It's not a bad price (EPA/$) though if you aren't a costco member. >> > I've frequently seen a claim (often in advetising materials for Nordic >> > Naturals) that if your fish oil capsules cause fish-flavored burps, [quoted text clipped - 45 lines] > expensive per mg EPA than Kirkland.

In the beginning weeks 10 years ago I did have fish aroma burps, but it went away for good after that. I take fish oil capsules for its omega 3 benefits. In fact I have forgotten about it. Tom |
