  • Vitamin A poisoning from liver?

    Hey there, I'm a long time lurker, first time poster.

    Due to a little over-enthusiasm and not realizing that Vitamin A poisoning was a thing, I recently bought 2 lbs of lamb liver at the butcher, figuring it would feed me for a couple days. Well I just got done cooking it all(although due to the recipe I had it's really only seared.), and only now realized that it would be unsafe to use it as my go to food for the next couple days.

    I'm trying to figure out whether or not there is any way to eat it all before it goes bad without poisoning myself. Should I just put one pound of it in the freezer, come what may? Should I eat little portions of it with every meal to allow my body to process all the vitamin A, or does it not matter? I doubt I could convince my roommates to eat any. Anybody had a similar situation in the past?

    You'll feel a mild stomach discomfort long before any symptoms of vitamin a toxicity. It's overblown, nothing really to worry about from 2lbs of lamb liver.

      Agreed. You might regret it because of the aforementioned stomach discomfort but likely won't get toxicity symptoms.

      Also, if you portion it up into 1lb portions for two separate meals, say, toxicity is even LESS likely.

The metal in my head clangs and clings as I walk - freaks my balance out. So the natural thought is just clogged up. Totally clogged up. So we need to unplug these dams, and make the the natural flow... It sort of freaks me out. We need to unplug the dams. You cannot stop the natural flow of thought with a cling and a clang..."

        I'd eat one pound now, and another pound in two or three days.

          I'd do what Knifegill says. I've done it myself. I'm only 5'3" and a couple pounds of beef liver over a few days is no big deal.

            Sweet, looks like I'm golden. I'm pretty sure it's about 5 separate meals for me, including the bacon/mushroom/onion sauce I'm topping it with. I'll just have to remember not to eat liver again for a couple weeks

              Yep, I agree that the concern about vit A toxicity is overblown. If you are supplementing heavily with concentrated Vit A pills then you could get yourself into a jam but when getting it is from natural sources, not a problem.

              At the risk of a WWGD story, do you think Grok would have passed up second helpings on liver because of fears of too much Vit A? Hell no. If he just killed a wooly mammoth, he would have eaten his face off on liver and then maybe not had any for a while.

                  I faintly remembered hearing a story long long ago about a Homo Erectus fossil that was found to have died of Vitamin A poisoning. But I guess I only heard of it because it's one of a kind(Also I don't think there are many carnivore livers in your local farmer's market)

                    I've read that Vitamin A is balanced out by Vitamin D and maybe K so maybe just supplement a bit extra if you're really worried.

                    I wouldn't be though, I went liver crazy when I first went Primal and survived

                      I'm now eating liver and kidney two or three times a week, mixed with ground beef/lamb onions and mushrooms. I'm probably only getting 50 - 75g of each at each serving though. But no, I wouldn't be concerned about eating liver weekly e.g. liver and bacon, liver and onions or 2 or 3 times in a row and then not for a while. Both those dishes were staples of 'home cooking' for many years in the UK and we're talking big slabs of liver not the 'added to' that I'm doing.

                        True, polar bear liver is supposed to not be a such good idea also. Darn, no polar bear liver pate'.

                        But that link only says this, "This 1.7 million-year-old femur (thigh bone) of a Homo erectus female shows how scientists can sometimes determine an individual’s cause of death, even after fossilization. An abnormal outer layer of bone on her thigh shows evidence of bleeding just before death. After consulting doctors and accounts of wilderness explorers, researchers concluded that an overdose of vitamin A—perhaps from eating a carnivore’s liver, which concentrates vitamin A—caused the bleeding and her death."

                        Lots of things could cause bleeding before death. It's interesting speculation but I don't think that it is anything definitive.

                          I wouldn't worry about vitamin a overdose from foods. Even very high doses are supplemented to women for menorrhagia without any harm.

                            He addresses the poisoning issue as a part of this video and to my mind says basically not to worry.
