    Has anyone ever overdosed on Vitamin A? I think I may have done it a couple days ago. I ate a big serving of liver because I was psyched up about getting some trace metals, but I didn't think about the Vitamin A. I get enough already with my regular diet through eggs and leafy greens. The liver gave me great energy that evening, but the day afterwards, I was so lethargic at work and I barely had the energy to walk or even stand. I also felt nauseous and as though I was running a fever. I read that to counteract Vitamin A toxicity, you could take Vitamin E, zinc and calcium, among others, so I'm gonna give that a try now.

    i think you'd have to eat a lot more than what you did for it to be toxic

    You would probably have to take vitamin A pills or supplements to actually have an overdose.

    From my understanding, vitamins A, D, E, and K are vitamins that people can seriously overdose on if taken improperly.

    A polar bear liver could put you in trouble, but a farm animal one is safe, unless you eat livers three times a day, days after days.

    the liver is the master metabolic organ in the body... as a result it serves as a filter and removes heavy metals and other toxins in the body. eating liver should be done rarely if at all to avoid consumption of these toxins... vitamin A is the least of your worries.

    organ meats = Food. Most. Foul.

    Probably shouldn't really eat pumps and filters anymore. Calves liver maybe (?) a little but chicken, bovine or pork liver isn't the best for you because of all the chemicals and drugs they pump through livestock these days (since the '50's) in the confined animal feeding operations. Maybe livestock that's grass fed and raised organic? Probably cost a small fortune. Yup, bear livers of any species are bad news for humans. Elk/deer liver maybe from non ag. lands? I bring them back to the old guys at work who still eat them.
    I don't suspect you OD'd on vit. A. Sound like you had a relapse of mono or some other virus. Fat soluble vitamins can build up and become toxic yes but you'd have to be mega dosing.
    "Nutrition Action Health Letter" put out by Center for Science in the Public Interest annually publishes a review of what they feel is safe levels of vitamin supplementation. Also what they feel a review of the recent med. literature indicates is effective and others that there just isn't enough data to say one way or another if there is a benefit to take additional supplementation.

    I was on accutane years back, which is a large dose concentrated vitamin A derivative and there was a risk of vitamin A toxicity and I talked to the doctor at the time and he said that I would still have to take a vitamin A supplement while on the accutane plus a lot of food enriched in it for it to occur. You should be fine.

    Okay, looks like I wouldn't have overdosed, but my liver is messed up anyway, so maybe it didn't like processing it. I was on Accutane twice too, which has caused various problems down the line.

    hmm, it doesn't mention that vitamin A toxicity has fever as a symptom.
