Vegan for 17 years. Eat sweet potatoes every day. My levels of serum vitamin A were way too high. Doc asked me to stop eating them. Must be a freak of nature. Also, was looking for at least one case study of deficient vegans. None found.

If it’s true that you don’t get enough vitamin A from vegetables why is it that people who are 100% Plant Based have healthy eyes and vision when compared to omnivores.

I don’t know if it’s a coincidence but I’ve been taking COD liver oil for around 2 years and I swear I’ve noticed a vision change. Is that just a coincidence?

I started eating beef liver once week and my energy levels have soared up the chats. Dr Berg's advice is a life saver!

I'm excited . Rat's milk cheese is what I've been craving for years

Where the hell is this 9,000mcg a day coming from? "RDA: The Recommended Dietary Allowance for adults 19 years and older is 900 mcg RAE for men (equivalent to 3,000 IU) and 700 mcg RAE for women (equivalent to 2,333 IU)."

Dr. Berg.... I REALLY appreciate you and my goodness your humor is fantastic!!!!

Bugs Bunny has left the chat.

Congratulations Dr. Berg for 4M subs! Thank you for helping save millions of lives through your channel. We appreciate and love you very much! 💙👏🏻🔥

I don't think it's a defect it's a sign that we don't need vegetables in our diets, not all of them but some.

Eating liver has changed my life. The energy and nutrition you get is insane and you only need a small amount every day

I think this is a very one dimensional line of thinking. It's not like vegetarians and vegans are running around blind and night blind. A lot of things are at play in the body.

I keep cod livers in their own oil in my pantry, and try to remember occasionally tap into a can. I also eat dehydrated liver chips (Aarnivore Aurelius) a regular basis. I don't use a lot of butter, but when I do, it's Kerrygold (grass-fed.)

Sheep cheese, then feta cheese made from sheep's milk.

Beta carotene is only coverted at 8-25% and 45% have an SNP in the BCM01 gene that produces the enzyme in the liver than converts beta carotene in retinol. As well as that you need to eat fat to absorb beta carotene.

Thanks dr.berg for your great information.3mos of following your advice and lecture and i can say i reversed may type 2 diabetes from 7.2 now im.5.6.great help

The advantage of plant beta carotene is that the body only converts as much as it needs. Excess vitamin A is toxic. Toxic vitamin A levels can occur if you consume too many supplements or large portions of animal food sources. Besides, our body fat stores Retinol for a longer period compared to many other Vitamins. Hence, beta carotene is the 'safer' precauser. Of course if you are having severe deficiencies, advice given in this video will be useful.

I've told this to people so many times, it's annoying that beta-carotene is listed as vitamin A on food labelling. If I eat foods with vitamin A my acne clears up, if I don't eat foods with vitamin A I get acne. No amount of vegetables clears my skin.

So let me get this straight. Vitamin A needs to be consumed in retinol form. You can't get it unless you gonna eat buckets of kale, carrots, raw, carrots. So one way to get the best amount of Vitamin/retinol is from sheep cheese. But the highest way to get vitamin A/retinol is from a rat? Now, how am I suppose to get this vitamin again?

Why 9.000 mcg? The recommended daily amount is just 900 mcg for adults 🤔

Remember to take a fat with vitamin A. The fat helps absorbs all the vitamin A retinol

And this is why apes, monkeys, gorillas all still have large guts. All those plants they have to consume on a daily basis just to meet their caloric needs. They are constantly foraging for edible plants and eating for up to 20 hours of the day

I don't know why you're talkiing about 9000mcg, the RDA is 900mcg. Half a cup of carrot is equivalent to 51% of the RDA of RAE. Eating vegetables cooked will absorb absorption a lot, especially with fat. RAE takes into account absorption variability.

conversion from Beta-Carotene at best is actually 6%, from Papaya.

If you add black pepper to carrots and vegetables it increases the retinol absorption rate. I learned this a while ago. No I’m not vegan.

Vitamin A is important for normal vision, the immune system, and reproduction. Vitamin A also helps the heart, lungs, kidneys, and other organs work properly. There are two different types of vitamin A.👍

I just want to put a caveat out there. I have been detoxing from hypervitaminosis A for a few years now. Years ago I did take fish oil and also ate salmon or sardines daily which are high in vitamin A. I also took a multivitamin that contained vitamin A. I quit these after having a visual aura which is considered to be a type of migraine, although I experienced no pain. After another year I continued to have various symptoms that kept getting worse, including: bone pain in thighs and back, headaches that would last weeks (sounds crazy, I know 24x7), waking up with an inability to go back to sleep, ringing in the ears, sudden onset of sleepiness while driving that would often come over me within 5-10 minutes. After these symptoms and more continued to gradually worsen over a year, I realized I still had large amounts of vitamin A in my diet, in the form of 4 eggs a day and heavy cream in my 3-4 cups of coffee. I quit these and then began to have incredible pain in my liver and bloating of my stomach. Then more headaches, cramping and multiple other pains. Most doctors will not know how to deal with this. If you've taken too much vitamin A over the years, it can be deadly. The scariest case I saw on PubMed other than death, was a guy who needed a liver transplant after 4 months of symptoms getting worse after discontinuing vitamin A. His doctors had no solution other than discontinuing vitamin A, until he deteriorated to the point of needing a liver transplant. They published the results as a recommended course of action. You can find it on PubMed. However, I did find the only known way to counter the toxic effects of hypervitaminosis A, and that is with vitamin D. The doctors for the case above, obviously did not know this so proceeded with a liver transplant. Vitamin D neutralizing the toxic effects of vitamin A was demonstrated with rats in the 1950s. There were a few more studies but they are still old studies. That said, I ended up taking higher and higher doses of Vitamin D as well as complimentary amounts of vitamin K2, magnesium, B complex, phosphatidyl choline and trace minerals. This all took a lot of research to put together. Especially important is needing comparatively more K2 with really high doses of D3. I was taking doses of 120,000 IU of D3 a day, spread throughout the day and it was still not enough. I eventually got up to 180,000 IU of D3 a day, every day for months. Note: none of these numbers are typos. I was really worried about doing this while I was doing this. I would try to taper down every so often. Sometimes I could sometimes I couldn't. Balancing magnesium was dealing with the consequences of intense muscle cramping or diarrhea. It's not always easy to find that balance. I realized that the K2 also eased the cramping. If I had sensitive teeth, that means I need more K2 because gums are receding. Plenty of other symptoms with skin and other body parts as well. Just too much to include here. Anyway I've learned a lot since taking these megadoses of D3 since February. I've got some graduate level texts, monographs devoted entirely to Vitamin A, it's biochemistry, etc. Overall, what I've done has worked. I'm feeling much better now, but I am still taking 60,000 IU daily. When I step down to a lower dose, I'll notice if I get a twinge of liver pain. If I do then I go back up to where I was. So the main takeaway that I'd like people to know is that Vitamin A has a very long half life. The longest half life of any vitamin. Depending on the study, about 130-150 days. So figure about 3.5 - 4 months. I have gone over 2 vitamin A half-lives now, so that means I should have less than 25% of my original vitamin A load. Yet I still need to take 60,000 IU of D3 daily. I don't enjoy doing this. I want to bring down the amount of vitamin D that I take as soon as my body will allow. It takes about 6 half-lives to get down to just above 1% of whatever that high load was. There are no good measures for the total load. Also vitamin D3 has a half life of about 3 weeks. This varies according to the study, but it is much shorter so you burn through vitamin D much faster. The half-lives of K2 range from hours to 3 days depending on the MK-version you take. I can definitely verify this with my non-scientific self testing. I recently went to the emergency room for an unrelated matter. They did several blood tests. They didn't notice anything wrong with me regarding this and I didn't bother mentioning it. So I just wanted to relay this anecdote for anyone who happens to be interested. And to reiterate the very important take away. The long half-lives of fat soluble vitamins. Vitamin A has a ridiculously long half-life. So don't overdo it. Great content as usual, Dr. Berg.

*Inner skin* - this makes so much sense to me. When I used to tell GPs that the inside of my lungs were itchy & I have to cough & dig under my ribs to try & relieve the itching they just used to look at me. I'm sure they thought I was mad, Lol. I also had itching in my inner ears (where only a cotton bud can go), inside my throat & on my inner eyelids. It used to drive me crazy.

😂😂😂 no, "Enough milk from your pet rat?"

I cannot find vitamin A retinol anywhere in the world. The vitamin A which can be found is Vitamin A retinol acetate (there is a difference of formulation of retinol and retinol acetate)

Hello Dr. Berg, I am on a vegan diet for over 10 years. Since I do not have those health problems you talk about in the video.. I wonder where do I get my vitamin A from?

To milk a rat, you must first get a very small stool and a very small pail... 😂🤣😂🤣😂🤣😂🤣😂🤣

*_A friend of a friend had a neighbor that eats 2Kg carrots each day-Oboy did she have the most amazing golden tan! Sure, she was a lot in the sun each day spring/summer, but that orange gold like hue was from the 2Kg carrots/a day._* *_Now, "2Kg carrots a day" is NOT Keto. But what about taking beta-carotene tablets that give you this orange glow? When I have checked forums, most comment: their sun eczema does not appear when they take beta-carotene pills and the "tan" is a nice bonus?_*

Dear Dr.Eric berg. If this is correct myself who is a pure vegetarian from birth cud have gone blind as we only take little butter at times eggs in cakes. So why is that?

QUESTION: We've all been taught that the moment you cook food it loses nutrients. HOW DOES COOKED KALE HAVE 9 TIMES THE AMOUNT OF VITAMIN A THAN UNCOOKED KALE? Was that a typo?

This is a recipe for Heart Disease, Arteriosclerosis, Type2 Diabetes, Stroke’s etc etc.

my cat loved this episode after listening about the benefits of rat milk

Hard to find a stool small enough to milk a Rat. 😂 Great content as usual.

I was vegan for years without taking Retinol tablets. How come my eyesight was good?

BRB busy milking my rat

I have UC. How can I get vit A and what is the best type of supplement to take?

I thought recommendation for Vit A by the RDA is 900mcg?

Finally someone said that! We dont produce vitamin a as other animals. The conversion rate of vit a is like 3-7%, most people dont even have a mutated gene to do that

I’ve said it before and I will day it again.. Your my favorite Doctor! Thank you 🙏 I just learned more great info from you !🙏❤️

Consuming 20 pounds of carrots. HAHHAAHHAHA. I love these jokes. edit: HAHAHAHAH rat milk

I have a couple of questions. 1. Years ago, they said that it was the actual conversion process of beta carotene to vitamin A that helped your body out not the actual vitamin A itself. Is this not the case any longer? 2. Your chart shows that cooked vegetables give more than raw vegetables. Is vitamin A actually more accessible in cooked vegetables? They say cooking normally lessens the benefits. What is happening that vitamin A is higher in the cooked vegetables?

my vision became painfully light sensitive with too much vitamin A! it happened a couple times. not sure of the exact time frame, but i had 8-9 oz total calf liver servings throughout each week across 1 or 1.5 months. vitamin A stores in the body and accumulates. light sensitivity returns to normal in about 1-2 weeks after cutting back. the vitamin A abundance in liver has a great cavity sealing you may notice. it also has extreme toothache relieving benefit in about 12 hours of consuming 8 oz. ;)

Doctor i eat raw spinach, raw carrots each night. They're still a lot of benefits because I've over come anxiety disorder since diet change. But i add a multi vitamin daily also.

Its not vegan vs omnivorous. But vegan vs unhealthy diet. Dr berg has said that unhealthy diet will depleted ur body nutrition. I think thats why the vit requirement is so high, but in this video show that vegan should have vision issue but its not. I think there will be needed ' adjust' min daily needs of nutritions for right healthy dietary.

Yes, yes, and more yes.

😂😂 it's very difficult to get rat milk .

Ok for those confused about where the 9000mcg came from. So Eric essentially normalized for 3oz of beef liver and used that as baseline hence that number. As others pointed out RDAs call for 900mcg and the upper limit (ul) is 3000mcg. So max you would need to consume is 1/3 of the numbers shown across the board. Confusing but the point is still valid; it only takes 3oz of liver compared to the rest.

Can’t stop laughing at the “PET RAT MILK” 😂😂😂🤣🤣 Love your sarcastic sense of humor Dr Berg OMG I’m going to pee in my pants 😂😂😂😂😂

You have a beautiful sense of humor in your presentations too. 👌

Yt channel Mastering diabetes states that the ketogenic diet is very dangerous? 😬

isn't 9000mcg ten times the FDA recommended daily intake???

Thank you Dr Berg for finally making this video! There is too much misunderstanding with people thinking they are getting vita A from plants, especially with all of the misinformation out there. Beta carotene carotinoids are not the same as retinol. Vita A retinol is a fat soluble vitamin after all. Can you do one next about Omega3 and the same misunderstanding about it?

This is why I have a rat barn, so when it's milkin' time I get enough milk and the highest productivity output.

What the heck do you do when you have food sensitivities to dairy, wheat, eggs and the thought of eating liver makes you want to barf? That being said, on the odd chance you this Dr. Berg, can you shed light on lipidema?

Damn. I only put half a Carrot in my Coleslaw today, it was a big Carrot. Lol. No probs eating Liver though. 🤗 You've clearly never seen how big our UK Rats are, they're as big as Cats, & sometimes as big as people. 😏 Thank you muchly for sharing this important information with us all. Take care & stay safe & healthy everybody. 🎅❤🙂🐶

If I may suggest...don't say "grass-fed". I've seen what a well-meaning rancher consideted grass-fed...grass clippings. What was especially telling were the golf balls in the pen...they were getting grass clippings from golf courses which are HEAVILY sprayed and usually GMO grass cultivars. Say pasture-raised instead.

I love the deadpan humor with the 40 lbs of carrots and milking your pet rat.

I'm confused. Is 9000 micrograms of retinol the recommended RDA? I saw in the link you posted that it's 900 to 1500 micrograms for men and 700 to 1200 for women. Can you explain the 9000 micrograms you have in your video?

Cronometer confused me from tracking vitamin A- when taking Dr Bergs cod liver plus a kale smoothie (real kale) a day, I was over 700% vitamin A requirements THANK YOU Dr Berg for the clarification! I thought I was overdosing my requirements and was super scared! 😊

We need 9000 mcg vitamin A daily? I thought only 700 mcg from Google suggestion...🤔🤔😲

For my rat milk, I just have to find and catch the rats living with me in my house.

thanks, ive been having a problem with dry skin. and throat/sinus. thank you. i will have to save to buy but will order dec. 3. 20 lbs of carrots :D

I am a vegan/vegetarian so I can only get mine from veggies. Can't eat butter/ Cheese due to a Gallbladder issue following a Sudden Cardiac arrest during a charity bike ride. ( Was very fit & healthy before the accident & NO family history or prexisting heart issues) I'm controlling the GB issue by following your KZfaq videos.

Liver as the highest vitamin A.Bete carotene has to be converted into vitamin A. Some people have a problem with the conversion for what ever reason.

Interesting again. Story im 74 and been low carb for near 3 years. My eyesight is so improved , along with so much else but my eyes are improving so much i almost don't wear my glasses at all. Kind of amazing to me.

Am using rosita cod liver oil for 3 year old he is 13.8kg how much would you recommend please am currently using 0.6ml I feel thank you 🙏 My son is keto two meals a day gluten-free dairy free we 7-10 vegetables and fruits coconut oil avocado oil ghee avocado milk organic grass fed meat chicken and salmon Fiji water and bone broth was diagnosed with autism I just want to say thank you for all you hard work

I couldn’t stop laughing! I love Dr Bergs dry sense of humor 💕

Im from India . Whether Mutton/Chicken liver has vitamin A?

this guy is a genius and a great input to the world

Dr, I am following the keto diet strictly but am not seeing any improvement could u please advice?

😂😂😂 RAT MILK!!! 😂😂😂 THIS IS HILARIOUS!!! 👍👍👍

Thankful dr Berg for Inlighten my mind for vitamin A. It is so useful topic

The problem with Cod Liver Oil is, 1: it is Over filtered and all nutrients are Removed. or 2: If Not Filtered, it comes to you as Being Rancid. I have Not been able to find Any brand that is any good. I have a Very high rated brand, i see it was 3rd party tested and came back as Rancid.

How does cooking the carrots make them a better source of vitamin A? I wish you would do a video describing the effects of cooking on vitamins. Is beef liver that is not advertised as grass fed still a good source of vitamin A?

Dr.Berg May I ask how to start to do my keto I had fatty liver and Gerd please help thank you.

Dr. Eric Berg you are the best!!!!!!!

I know its not keto, but i think Roasted Sweet Potato has alot of Vitamine A. But is it the active one?

I’ve been eating more Grass-fed beef Liver. But it can be very chewy. Still experimenting with ways to cook it. Pureeing it in the blender before cooking is something I might try.

I also cannot disassociate and say "grass fed liver" It came from an animal who was using their liver for themselves. The liver isn't running around consuming grass to make sure it's supple enough to consume for other creatures.. sorry, I just don't understand this whole eating other animals thing anymore. Started to think about it.

And what about eggs? I don't eat meat or dairy products, but I eat eggs and fish, can I have this amount of vitamin A just eating some egg yolks?

Does Cod Liver Oil come in a pill form, and if so, what is a good brand to buy? I am having trouble driving at night. I definitely would like to try this. Thanks.

Rat milk should be easy to get if you live near the sewers.

it's very urgent, please. we want a special video for people who were born by cesarean section, we did not have the natural microbiota of our mothers, after our birth by cesarean section, we triggered asthma attacks, allergies, until now we suffer, we have consumed too much antibiotic, now we suffer from resistant bacteria, fungi, inflammation all the time and for everything, digestive problems .... we want a solution please.

Say “sheep cheese”, ten times, quickly 😂 Have a good weekend :)

The more I learn, the more sence a carnivore diet diet makes! Or at the very least, eating more Organ Meats!

should we consume 9000 mcg of vit A in a day ?????

I went on accutane, and now everytime I use retinol cream I get headaches. Also my skin was always very flexible now i get these weird marks on my arms and belly looks like wrinkles. CAn you make a video about what happens when you take accutane and how to live after it?

why do you get less from raw weggies than cooked ? dont the cooking destroys the vitamines ?

watching this while enjoing a huge glass of rat-milk

I am vegan, sir could you please suggest plant based super foods for vitamin A. Please help.

There has to be some other way to get enough retinol. I don't eat any of that stuff, except the butter. And I don't want to eat more butter.

That explains my cat's amazing night vision.

Please offer your recommendations for a good Multivitamin supplement. I am a Vegetarian. So B12 and Omega-3s EPA/ DHA probably aren't the only nutrients I am deficient in after all.

Dr. Berg, you underestimate my rat. She can give milk to 12 cubs no problem

DR. BERG: This is the funniest video you have ever done. Vegan approved for sure!
