This is what Dr. Peat said about the polar bear in an interview with Patrick Timpone in 2019@Sumbody , Vitamin A toxicity is not a "hidden" agenda or obscure topic. Hypervitaminosis A is all over Common Medical Literature. There is no debate in any medical forum that Vitamin A toxicity exist. It very real, so real that 1 serving of Polar Bear liver is Lethal as was deadly for some explorers. Now, whether or not it is a straight up toxin, or a vitamin is debatable. But for people to be concerned on how much vitamin A they are ingesting and or storing is very responsible. Vitamin A overdosing is linked to Liver Cirrohsis and OsteoPorosis. Not something I want to play around with.
Many forum members now agree that Ray was very wrong on this subject. Especially now with the work of others showing the links between high vitamin A intake and hypothyroidism. Now we know why Ray needed to take so much thyroid hormone, because his Vitamin A intake as so antagonistic to his thyroid. Garrett Smith has many papers on the connecting between Hypothyroidism and vitamin A.
PT: Does Dr. Peat think there's anything to this more and more people talking about vitamin A toxicity? Seems to be a new thing that people are kind of clamouring about. Anything here we need to look at in your opinion?
Dr. Peat: In 1973 and '74, the drug companies were coming out with synthetic vitamin A products. They found professors around the country to tell stories. One at, I think it was University of Oregon or Washington, put out the story that she had seen patients go blind from taking vitamin A. There were several professors with stories like that coordinated apparently through the advertising departments of the pharmaceutical companies selling synthetic vitamin A. I contacted these professors. They wouldn't talk to me. It was obviously just made up stories to make people fear vitamin A. One of the popular stories is about some explorers who ate polar bear liver and their skin fell off in the following days. There are lots of toxic things that a polar bear's liver might contain. But they chose to blame it on vitamin A. In animal experiments, huge doses that would be greater than you could get from polar bear liver never produce symptoms similar to what the polar bear liver supposedly caused. So there's a history of trying to create panic. That's going on with vitamin E. People are saying vitamin E causes heart disease and cancer. They have products to sell that might cost $1,000 or $10,000 a month......................
Yeah, experiments with baby chicks. I think they were giving them something like a million units of vitamin A, which caused brain deformity. Their brain stuck out of their cranium as they developed. But if they gave them a moderate amount of vitamin E, the vitamin A was no longer toxic. So what was happening was at a certain very high level, vitamin A auto-catalyzes. It stimulates its own oxidation and degradation. And the symptoms of vitamin A poisoning become similar to vitamin A deficiency. And both of those are prevented by adding vitamin E, which prevents the breakdown................
PT: Does the oxidative stress cause the lipofuscin accumulation, or is it the other way around, in your opinion?"
Dr. Peat: It's both. When lipofuscin lowers the oxygen tension, it acts as a catalyst, taking fuel directly to oxygen and creating an oxygen deficiency. And that oxygen deficiency imitates what happens under stress or in the presence of estrogen. The low oxygen creates the catalytic condition to further degrade any polyunsaturated fat that's in the environment. And vitamin A can contribute to that. An excess of vitamin A, without E, interacts with the fish oil or other unsaturated fat to lead to the accelerated production of lipofuscin
PT: Oh, so the E helps with lipofuscin if you're going to do some pufas or something.
Dr. Peat: Yeah, it's the main... That was one of the things that led to vitamin E research was discovering that it prevented lipofuscin and the brain toxic effects and testosterone suppressing effects and so on.
PT: So, would your fave be then one of those like mixed tocopherol kind of vitamins?
Dr. Peat: Yeah, I think the mixed product is the best.
