I read with interest a recent question regarding use of Omega-7s (which I had never heard of!). I have had continuing itchy skin problems even with a strict gluten-free, soy-free, paleo-type diet. Decided to eliminate the fish oil and cod liver oil. Lo and behold, itchiness has disappeared.
Has anyone else had negative symptoms that they can trace to Omega-3 supplements?
With the money I will save on fish oil, I can buy a second home.
My experiences with straight up tablespoon a day of Nordic Naturals Fish Oil has been softer skin.
Cod Liver Oil might be the culprit. Vitamin A in large doses can lead to itchy dry skin. It is the same effect as taking Accutane, a retinoid drug which dries out people's skin to fight acne (I took it as a teen--if only I knew about Paleo then). If you are taking multivitamins or eating liver or veggie vitamin A sources you might be getting too much.
I think the thing to remember is that omega-3s are not really a "supplement." They're fats -- which means they're food! I wouldn't take any other food in the form of a pill, so why would I take my polyunsaturated fats that way?
I stopped taking it altogether when I started primarily eating grass-fed lamb. The chicken and pork I eat here and there seems to be balanced out by the salmon, mackerel, shrimp and scallops I eat here and there.
It seems to me that it is most effective as a SAD adjunct that mitigates some of the terrible effects of it.
I resolved to ditch the fish oil. Every day one of my meals is about 100 calories worth of fatty salmon yielding 1.5g of DHA/EPA, there is another .5 in my lamb and all in all I only get about 4.5g of omega 6 so that all works out.
I still take my fish oil, never was taking ginormous doses though. I'm not convinced that PUFA ratios need to be as tight as some think they should, nor am I convinced that extremely low PUFA intake is beneficial/necessary. Most all foods are high in PUFAs and biased towards omega-6s - aside from beef (low in PUFA) and salmon (high in omega-3). Doesn't make logical evolutionary sense that our diets should be low in PUFA and 1:1 in omegas if that requires eating a very limited diet.
I just discovered I have a massive imbalance in Omega 6 and 3s that might be at the root of severe depression. Now my psychiatrist has me completely off all fish oils and a variety of other fats, and I am dosing heavily on raw egg yokes, butter, primerose oil, and a bunch of other specialty oil supplements and electrolytes. Generally speaking fish oil is probably good for most of the population. But for me it was making me sick because it was causing imbalance in my Omega 6's - most specifically Arachidonic Acid, which apparently has a big impact on many neurological and cellular body functioning. I would say anyone serious about there health should get tested for Omega 3 and Omega 6 ratio and overall levels first before mega dosing on Omega 3's. In my case I was making my self sicker by trying to be healthy just because I had an underlying imbalance in my body chemistry.
