I have a question about the Fermented Cod Liver Oil. I really can't afford it, I may be able to put it in the budget again when I return to work but right now I'm a stay at home mom. Is it even worth it to take the Carlson brand CLO that I'm taking right now or are the PUFA's so oxidized from the heating process that it's better to skip it?
Sorry if this is a repeat but I couldn't find this specific question in my archive search.
Carlson is a reputable company. They appear to take reasonable precautions to prevent oxidation in their processing and packaging. (Here is a description of their processing) The techniques used to prevent oxidation include: (1) processing and packaging under nitrogen instead of room air, (2) using "molecular distillation" which is done under low pressure and lowers the boiling point of the oils to use less heat, and (3) adding vitamin E to the oil.
Of course, another issue with cod liver oil is to make sure you don't overdose on vitamin A. You may need to take extra D and K for balance.
Here's the thing with both fish oil and vitamin D...you can solve both problems fairly cheaply. Go get sunlight and don't eat things heavy on n-6 fatty acids. The vitamin D comes free courtesy of your genetic inheritance and the sun. Reduce the n-6 intake and then you don't need to mega-supplement with the n-3s (which is probably counterproductive after a certain point). Barb's suggestion is good as well--sardines are cheap and if you have a farmer's market nearby you can probably get decent eggs reasonably priced (I can buy a dozen/$3 here in Southern California, where just about everything is ridiculously expensive). But really, just cut out the vegetable/seed oils, minimize the grain raised/finished meats and you don't need to spend a fortune on fish oil.
I was recently speaking to a chemist about this. PUFA oxidation is not that big of a deal, other than a waste. Your body will clear oxidized fats during digestion. It's PUFA that has been absorbed and then oxidized that's the big problem. So, if you consume oxidized PUFA, it's not dangerous, just a waste of what you're really after if that substance has been oxidized (i.e. DHA). If you absorb a lot of unoxidized PUFA, and then it oxidizes, that's bad.
I don't know about Carlson's. I bought a bottle about two weeks ago and took one pill and they gave me a strange heady high feeling. I felt like I could fly. The day after I experienced migraine like headaches. I was looking forward to my next dose and sure enough felt the same effects. Suspicious I studied the contents and realized I gleaned over the beef gelatin capsules. Beef Gelatin has been cited in numerous places to possibly contain processed free glutamic acid which is msg. I've recently stopped eating anything that might be contaminated with the stuff so I believe that I may be more sensitive to it. I took the pills back for a refund. The headaches were pretty bad. They went away soon after. My suggestion is beware!
I took Carlson's for a while, and it was pretty good, but I live in the South and last summer I got a bottle that I think was heat damaged- it caused inflammation. I stopped taking them. As to anonymous' headaches- in the beginning of my experimentation taking Omega-3 laden oils, I had hayfever-headache type reactions to the Omega-3s regardless of which type of oil I took. It seems the body needs time to ramp up whatever it uses to process Omega-3s. This happened when I started trying to get a gram of Omega-3s a day- fish oil and flax did it. I later found out that starting with a small dose and slowly going up helps.
Currently trying Seth Robert's recommendations. Flax oil may not be paleo, but it is refrigerated in the stores.
