No. Inasmuch as it's left it's permanent calling card, my condition has never been so critically life-threatening that I've researched any treatments outside the traditional medical community. My doctor has been spot-on with treating every biological quirk in my life, including the diabetes, so as long as he has my trust (earned though results), I have no reason to address alternatives. How, specifically, does cod liver oil tie into Type II?
Just google diabetes, cod liver oil....you'll finds lots of info....but, also it is best to get a Vit D, 25 Hydroxy test (best results are over 60).....here's one quote from research...."Vitamin D is essential to maintaining strong bones and teeth. It enhances the strength and efficiency of your immune system, which decreases your risk of developing autoimmune conditions. Vitamin D helps your body regulate its blood sugar levels, playing an important role in preventing type II diabetes. Finally, vitamin D is one of several nutrients that are necessary for preventing high blood pressure.
If we simply posit that a lot of Type II diabetics do not actually have a "disease", but are perfectly normal folks who have been eating the wrong stuff, adding cod liver oil makes sense.
Eskimos, for example, almost instantly develop Type II diabetes when they move to a Western (let's call it "Subtropical") diet with lots of starch.
Get them back on a sensible diet of seal, whale and fish, or fish products, and they're fine ~ the Type II diabetes just goes away as they simultaneously remove starch from their diet.
There are other groups or subgroups with a similar constitution ~ folks whose ancestors have lived on the tops of mountains for thousands of years, or in Arctic wastelands, or out on oceanic islands, or the Northwest European coastline ~ places where animal husbandry, sea mammal hunting and fishing were the primary sources of food.
Current federal laws regarding the hunting or importation of seal or other sea mammals deprive such folks of the opportunity to eat, for them, a healthy diet.
Beef is no real substitute.
