Don't Eat Turkey Liver!

Over consumption of vitamin A can lead to jaundice, nausea, loss of appetite, irritability, vomiting, and even hair loss.

I learned that the hard way. I don't understand why packages don't have warning labels Be careful about other kinds of liver, including liverwurst and cod liver oil. That's my guess as to why baldness seems epidemic in the UK. Obviously, stay away from Accutane. By the way, vitamin A toxicity goes with diffuse thinning, maybe concentrated at the front of the scalp.

Is it true that plant sources of vitamin A don't cause toxicity?

I think some forms don't get as absorbed as efficiently as others, but no, ultimately huge intake from any source will cause toxicity. FYI, the vitamin A in liver really comes from plants (if traced far enough down the food chain).

you must have eaten too much or the other food you ate just didn't combine right. I eat calf liver comparable vitamin A levels and I feel no ill effects ever.

It takes a long time to notice vitamin A toxicity symptoms. Of course I had other sources of vitamin A. Everyone does, and I was getting more than usual from other sources. For a while, it wasn't being held back by vitamin D, either.

Edit:
Actual consumption of vitamin A from food and supplements

"Based on the 2001 NDNS of adults (Henderson et al, 2003), 9% of men and 4% of women had intakes of retinol exceeding 1500 μg/day. The data show an age related trend: 1% of men and 3% of women in the 19-24y age group exceeded this level compared to 14% of men and 8% of women in the 50–64y age group."
Some of them eventually will have toxicity, and most of them will be men.

That's also where the UK hair loss theory fits well. A few hundred years ago, liver was one of the few sources of vitamin A available there. Now, with more options it's easier to go to extremes than it used to be and to also be lower in vitamin D. Consequently the vitamin A is too much for some people, and hair loss is happening earlier. Actually the data above shows it's probaby even more of a problem in the USA.

Hypervitaminosis a: A liver lover's lament
http://onlinelibrary.wiley.com/doi/10.1002/hep.1840080237/abstract
“More recently [by 1988], it was noted that a vitamin supplement of 2 capsules of 25,000 IU vitamin A daily for a couple of years was associated with severe vitamin A toxicity and a rise of the plasma vitamin A level to 10 times normal in a 16 year old and in ‘health’ food users.”
From a more recent article - http://www.sciencedirect.com/science/article/pii/0002934394903476
"vitamin A hepatotoxicity has been reported at doses exceeding 50,000 IU/day. At 25,000 IU vitamin A per day, although elevated liver enzymes may be seen, hepatotoxicity is rare."

My educated guess is that hair loss will show up by the time liver enyzmes are affected.

"Hypervitaminosis A is one of the more common types of vitamin excess. You can monitor yourself for it by watching the color of your palms, and by looking for yellow coloration in the places where you sweat. But the best way is to monitor your intake"

"Hypervitaminosis A can even be seen in people who take no supplements, if they live their life on carrot juice."

Okay, I found out that beta carotene absorption increases if consumed with more than a little fat. I don't know if that applies to other forms of vitamin A, but I know I'll be acting like it does when possible and consuming any major vitamin A sources.

I really doubt that vitamin A is causing hair loss it seems to reduce sebum and other benefits look at fredthebelgians testimonial he was taking I think 50,000IU a day for 3 months now takes 13,000IU I believe. It is impossible get hypervitaminosis A from carotenoids.

I've had an issue with yellow/orange skin tone since eating a lot of carrots. Raw, well cooked and juiced. However, my preformed vit a sources are only grass fed beef and very rarely grass fed butter. I took some vit A here and there for a little while (5000 IU a day), but plan on eating liver once a week soon. I believe I have liver issues, but not necessarily from vit A. I think it's from my lifestyle for years. Binge drinking from age 15 through 24/25. Eating as much as I could stuff in my body for purposes of gaining weight at the gym. All this while trying to stay low fat, high protein and not really monitoring my carb/sugar intake.

My hair loss and dandruff really took off the summer I tried cutting fat down to 20 g a day. On top of that I was working out a ton, drinkning, and burning the candle at both ends with a new office job and summer college classes. Stress, plus poor diet, plus alcohol... no good. I believe vit A is essential and a good food source of it weekly is a great idea.
