how much vitamin A

Commented on September 15, 2013

A long time ago I used to take 8,000 IU of Vitamin A daily. This stopped my acne 99%

I since stopped taking it because I read about vitamin a toxicity and it scared me haha! Want to be healthy aswell as acne free!

So my question is:

IS IT SAFE TO TAKE 8,000IU OF VITAMIN A DAILY?

I eat carrots, sweet poatoes, dark green leafy vegetables and lettuce on a daily basis (which are good sources of vitamin a I belive I was told)

Thanks guys

I agree with Matt, also, Matt this is off topic, but do you have any idea where my 10k points went?

also IIRC some food for thought, sometimes the vitamins are removed... or removed then added back in during processing, not sure why you wouldnt just supplement individually if you need them, or just get more sun and eat more beef liver.(A+D supplements are very cheap)

TL:DR - be careful, fish oil/fish liver oil can be tricky and detrimental if you get the wrong ones(usually cheaper ones)

(wouldnt let me post that in one comment)

i know kresser advocates fermented cod liver oil as a great source of omega 3 +d+A, but its pretty expensive. cod liver oil not fermented i think you have to be careful with, firstly because it shares the same downsides as fish oil(easy to oxidize), second it can come from fish that are predators(shark sailfish salmon) that might have excessive bad things(like mercury)

I take beef liver and make a sort of Philly cheesesteak with it, minus the bread though. Chicken livers are ok, you can make a gravy out of that, eat it on some potatoes.

I don't eat liver anymore but as a child the only way I could stomach it was fried chicken livers with onions and then all mashed up with hard boiled eggs into a CL salad, we used chicken fat but you could use any healthy fat. Calves liver could be subbed but I had to choke it down. Maybe as and adult I could do it but I'm not going to try!

You're not going to overdose on vitamin A from plant sources. The more you consume, the lower the rate of conversion in the body. Also goes that the conversion from beta carotene to vitamin A is also lower when you already have a high dose of vitamin A (retinol) in your diet.

Beta carotene will prevent serious vitamin A deficiency, i.e. you won't go blind. But it's unlikely you're converting enough for optimal health. Getting the extra dose of retinol (via liver) makes all the difference in the world for me.

I'm trying to get more vitamin A too. I've become aware that my daily carrots, greens, and orange tubers and squashes aren't giving me very useful Vit. A.

Sorry to hyjack the thread but on a budget and with no experience buying and cooking liver, what are good ways to get the stuff? I find liver pate kind of hard to find but very convenient. I've also read mixed reviews on the supplemental use of cod liver oil. Cod liver oil sounds like the easiest (and maybe cheapest) way to get balanced vitamin A and D but is it "healthy"? What about oxidized PUFA's? Are the A and D stable in this unnatural concoction?

great answer from torben +1. also great point from keepcalm as far as removing the dairy goes. also i think Vitamin C, omega 3 and Zinc may contribute to skin health? i think ive heard somewhere that excess water retention at the subdermal layer strongly contributes to acne(caused by either excess water retention or inflammation**same thing kinda as inflammation causes the former**)

Yay for you! Do you consume dairy products? I am in the process of trying to be acne free, and take about 20,000 IU a day of vitamin A, I just say watch your symptoms and if you want to absorb vitamin A, eat it with some lard and eat more healthy saturated fats.

Carrots and sweet potatoes do not contain vitamin A. They contain beta-carotene, which is a precursor to vitamin A, although conversion to vitamin A is poor and seems to be very unpredictable.

For real vitamin A (retinol), there is one source that beats any other by a huge margin: liver. Just as an example: One ounce of veal liver has about 20,000 IUs.

8,000 IUs of vitamin A don't seem to be a problem. Vitamin A toxicity And adequate vitamin D seems to increase the threshold for vitamin A toxicity (by approx. factor 10 to 200,000 IUs/day)

I recommend the following article on vitamin A for further reading: Chris Masterjohn - Vitamin A On Trial
