Vitamin A is actually a Cofactor of Vitamin D. Vitamin D gets activated from calcidiol into calcitriol which is the active form. Calcitriol then goes into the cell and binds to the vitamin D receptor. Vitamin A as the active form goes into the cell and binds to the Vitamin A receptor. Both receptors then melt into one. This means there is an important relationship. Dr. Michael Holic (scientist who isolated vitamin D) published a study on the interaction of vitamin a with vitamin d.
Since the pandemic I’ve been obsessed with vitamin D. A couple of months ago I tested for vitamin A and was shocked to find I was mildly deficient. So I take one drop of liquid vitamin A per day.
@@TiMalice2009 the serum retinol test is not a good indicator of VA status. It is actually very common to have low retinol in blood and be very high in liver stores, meaning you actually have hypervitaminosis A, and you are not deficient. this is in the research. it is extremely difficult almost impossible to be VA deficient in the US or other industrialized countries. it is in everything. dairy, eggs, and common vegetables to start. please do some research on this. taking VA as a supplement is often a huge mistake.
@@JYAN2852 yeah this concept is the most underrated thing in all the diet/supplementation talks. Every time you take a supplement, say Vit D, you should be eating it with a food that is naturally high in Vit D because it will naturally have all the other substances in it that helps manage that Vit D dose
Please also remember magnesium. Without magnesium, the vitamin D level will not rise above 30, maximum 40 ng / ml. Magnesium is best used transdermally (as an oil through the skin). When taken orally, probably only 50-60% of the magnesium is processed by the body. Those who think that all nutrients can be absorbed in the necessary quantity through food are unfortunately wrong. Due to the constant deterioration of the soil, water and air in recent decades, plants, herbs, berries, vegetables, etc. no longer have nearly the ingredients they did 50 or 60 years ago. We (unfortunately) have to resort to food supplements. And here it is particularly important to make sure that you take high-quality products...
i stopped severe toothaches in about 12 hrs with high vitamin A from 4 oz beef liver and fat from milk, as it re-mineralizes. D3, K2 should go with it, but didnt take during those times (still went to the dentist, dont neglect getting checked out). Its one of those things i had to try, and now have liver on a regular basis for its high A & copper content, + other micronutrients. Acquired taste for sure.
I have not had cavities in over 10 years I'm 27. I have however had tooth pain gotten it checked out. I found that when I am dehydrated my teeth start hurting especially my lower left teeth for some reason.
very important to note the difference between animal sources of vitamin a and plant sources also that synthetic vitamin a might be more toxic not all vitamin a is equal

Grant Grenereux cured his eczema and kidney damage with a zero vitamin A diet.

@@agentfifteen Vitamin A or actually beta-carotene in context asbestos or tobacco smoke? It is the latter. Beta-carotene is not yet vitamin A. In fact, the relationship is inverse not direct especially for retinol. As I eat animal fats, I have a good retinol intake.
Hi Mike - there are several well known health you tubers (keto/low carb) who are pushing against vitamin A saying it is toxic to the liver and thyroid. They say not to eat liver, or to restrict it to very rare occasions with the minimal amount. I happen to like the taste of liver especially lambs liver so probably eat it once a month. My thyroid and liver blood work are all excellent so I think I'll continue to eat it.
Who specifically is saying this? They likely don't know what the bleep they're talking about. That said, I think eating liver daily is not the solution, either.
Some ppl will not be able to tolerate liver. But it's most likely due to other causes not Vita A itself. Vita A is an essential nutrient after all. Bones, eyes, thyroid are a just a few functions requiring it after all. The people who cannot tolerate are the exceptions though, just as how some cannot tolerate fats. Fat soluble vitamins are very lacking in the general population's diet (low fat, low cholesterol, and plant base diets)
I live in California and have access to raw milk, sold commercially (tested), and I've had GREAT improvements in my health after a few weeks of drinking it daily. It makes sense since it has a solid nutrient profile. I also don't have a gastro reaction like I do with pasteurized milk.
Hi Mike, thanks for this and for all you do. Much appreciated! I highly recommend this book about the interaction between vitamin D3, K2 and A. Very interesting! It's called 'Vitamin K2 And The Calcium Paradox'. All the best way out of Luxembourg :-)

@@Palaecro Vitamin D intake may be insufficient by taking only CLO (Cod Liver Oil) As far as I know current cod liver oil contains less vitamin D than in the past. A couple of years ago, looking at the various brands of CLO, I noticed different quantities and proportions in the vitamin D and A content. I wrote several emails to the various CLO manufacturers available in Europe and to my surprise they all replied. Everyone admitted that vitamins A and D in CLO are added. The reason is filtration (and also deodorization) All fish oils and even CLO are currently subjected to various filtration processes to eliminate pollutants (unfortunately the sea has become a landfill) After filtration the vitamin content of the CLO is almost zero and they are therefore added again (synthetically) Depending on the brand there will be different quantities and proportions of vitamins. This doesn't mean taking CLO is a bad idea, I think CLO is good for our health but I wanted to tell you this. Some reading I did on the web says that the CLO of 50 or 70 years ago was richer in vitamins than today, this could be true.. Rather than buying CLO I take fish oil because it is richer in omega3 and I take vitamin A and D purchased separately. There is also a Nordic CLO and fish oil manufacturer who fortifies all their products with vitamins A, D, E - I sometimes use their fortified fish oil. I don't use megadoses of vitamins A, D or K2 but I am convinced that their synergistic association is beneficial (and I don't forget magnesium)

Yes, Beta-Carotene won't convert to Vitamin A in Diabetics or those with pronounced Hypothyroidism. This well established. Even the aged may have problems with this conversion, as they don't convert sunshine to Vitamin D.

Liver gets so much hate, but it's wildly undeserved. You just gotta treat it right - buy fresh, slice thin, cook fast/hot, pair with REAL butter - to make it both delicious and nutritious. Even my toddler likes it, and it's the first thing she cleans off her plate. Chicken livers are mild, tender, and dirt cheap. My favorite though, is rabbit liver from the meat rabbits I raise. If you can get ahold of it, and you know the animal was raised well/harvested in good health, it's well worth trying.
There is nothing delicious about liver. I was forced to eat it on a regular basis when I was a child. The minute I got old enough to refuse it and get away with it, I did. I haven't eaten it from any animal since.
I grew up eating liver at least once a week. We had it as dumplings in soup, as pate on bread, with onions, with sauce or breaded. I loved it in any form. We didn't eat it daily or in a huge amount. I still love it and eat it but now just pan seared in butter.
According to experience D:A = 1:1 (IU) gives energy. My theory (short version): cortisol hormon maintain blood retinol level when liver can't do that (blocked by fructose, alcohol or in rare case depleted). Energy production is controlled by vitamin A supply. If brain need more energy => ACTH => cortisol (and other hormones). But cortisol will decrease other organs vitamin A usage. White fat tissues are not energy stores they collect vitamin A and send back. So Fat covered organ is suffering from vitamin A deficiency. Heating is the largest vitamin A consumer but fortunatelly white fat tissues are either insulator. Immune system is also a large vitamin A consumer. In adult people you can't measure vitamin A deficiency in the blood only in emergency case. But you can measure vitamin A deficiency in the blood of child because cortisol is working differently in childhood. Cortisol turn off/lower body functions to save retinol for the brain but only supplementing with vitamin A won't restore we need the opposite hormone to restore. The opposite hormone is vitamin D. Because vitamin D and cortisol hormons have the same properties but in the opposite way. e.g. Cortisol blocks calcium absorption and bone building. Only natural forms of vitamin A are safe to take but only with vitamin D. Artificial forms are toxic. (e.g retinil-acetate is toxic for the liver because of water solubality). Taking only vitamin A for long term period caused toxicity is in fact calcium deficiency problem according to symptomes => you need vitamin D and calcium (+magnesium). And vitamin D toxicity is in fact vitamin A deficiency in the liver (very rare case) and in this case cortisol will spike above the vitamin D level and their interplay causes high calcium level and other problems. Your brain can't get enough vitamin A (energy) so you will have fatigue, anxiety, depression, etc... Stress is a situation when brain need more energy...
Any resources or links to make sure those with renal insufficiency get enough vitamin A without causing issues? Love all your content! So well disseminated
Thank you Mike, much appreciated. Good support for me continuing with Cod liver oil. Especially during the northern winter months. Will forward to others.
Interesting... Assuming white cells are produced by default, this could explain how vitamin A deficiency might lead to an overactive immune system, as well as anemia. (I haven't researched this, yet -- just speculating!)
My story. One of my sons and I are not vexed. We got the virus. I had been taking vitamin D. C and zinc for many months prior. I've actually always taken vitamins. Our symptoms were relatively mild. My son who Is 25 symptoms were a little worse than mine. For example He had fatigue that I never experienced. In fact I carried on my days as I normally did. We both got it again from my other fully vex and boosted son who got it from a fully vexed and boosted friend. My unvexed son and I had very mild symptoms. They were a nasal drip and scratchy throat. Pretty similar to our inital symptoms when we got it the first time. The symptoms never progressed and after approximately 48 hours we both felt completely fine. My vexed son wasn't as lucky. While his symptoms were relatively mild they were worse than ours and lasted about a week.
Im curing an ear inflammation/infection of several months stubborn standing, with Vit A, 4 tiny pills twice a day, cod liver oil. first dose one evening, the next morning I could already feel a good difference. I also take Vid D and zinc every day or every 2nd day, but the inflammation/infection refused to give way UNTIL i took Vit A.
You are right Vitamins A and D are essential to reinforce our immune system🦠 ; some of my favourite whole foods: liver, salmon, eggs, broccoli (too many to list here); use to supplement with CLO however, was afraid of getting too much due to consuming whole foods; however, if one doesn’t get enough thought, it’s a very good idea to supplement; thank you.
The side effects of Vitamin A toxicity from Accutane is not good. I took that drug and regretted it. I suffered from dry eyes, mouth, and skin for over 5 years. All I had to do was simply change my diet and cut out all processed junk foods. It has taken me many years to finally get back to normal. The carnivore diet also helped me out a lot and has kept my severe cystic acne from coming back.
@@BiggieCheese45 I didn't have any major side effects and only stopped taking it after noticing my T levels dropping. Should have done keto/paleo from the beginning but too late now. My skin is much better than before though
@@bjoshua1980 I took Isotretinoin and went up as high as 50mg 3x a day for 2 months. It started at 10mg, 25mg, 40mg, and then 50mg. I took it for almost a year.
I’ve been searching for the optimal amounts of vitamin A to consume daily and all I can find is the RDA. We know rda are not optimal levels. Do you know of any studies that have researched the optimal levels?
I think the best thing is to take vitamin A along with D and K2. They work in synergy and by increasing the dose of vitamin D the doses of the others must also be increased. The toxicity threshold of vitamin A is related to the presence or absence of D and vice versa. To give an example, above a certain threshold zinc can also be toxic but if you add a little copper the toxicity disappears. Probably above a certain dose the cofactors become essential to avoid problems, the RDAs are just numbers that do not take into account the interactions between the various nutrients.
Could you do a video on remedies for seasonal allergies? Such a widespread problem that seems to be very poorly understood / have few effective solutions.
I've been able to get over my seasonal allergy problems but I'm not sure if it was supplementing with Vitamin D, A or C that did it. FWIW my Vitamin D levels were low before supplementing.

Great video Mike, I really like the info you share. Health is important. Small request, please don't forget to mention how important it is to take Vitamin K along with Vitamin D.
I've had a similar experience. Last year started taking vitamin a then after about 2 months broke out with psoriasis (never had it before) and sinus problems. My eyesight has gone worse too. I've been hearing lots of conflicting information regarding vit a. Dr Garrett Smith seems to think it can become overloaded quite easily and suggests detoxing from it. On the other hand Dr Chris Masterjohn seems to think you can go full send as long as you pair it with adequate vit d. Not sure which to believe as they both have complelling arguments. I still have the psoriasis and have noticed having cod liver oil or liver makes it worse about 2 days after. Never used to have any issues with either before that short stint of supplementing vit a.
i know there's something in vitamin A for immunity after i finished my accutane. Before im having terrible cough almost 3times each year. During my low dose course, i didn't have any coughing episode or got Covid... 4 months after finishing accutane i got Covid and productive coughs came back again
I've heard U can take up to 500,000 IU for a couple of days if U R sick! And over a 120lbs but know the right type I use 'Carlson's" definitely stay away from synthetic Vit A
@@BankerSinbad Neither. Carotenoids are not Vita A. They are pro-vitamin, a precursor. Very little as low as 2-3%, if any, actually gets converted in the gut. Amount varies from person to person. Better to get the real forms from fat sources. It's a fat soluble nutrient after all
@@JYAN2852 bro you won't believe, a 48 year old was hospitalised due to Hypervitaminosis A, because he use to eat 5-6 pounds carrots a week... What would you say now?
Vitamin A maintains external cell membranes and surface glycoproteins and cell differentiation deficiency is linked to thymic lymphocytes increased severity of bacterial and viral infections
Dr. Garrett Smith is the guy you need. He did extensive research on how toxic Vitamin A is, how your liver accumulates it over the years and gives you health problems. It’s not even a vitamin, but a toxin.
Actually, there are 13 vitamins,9 of them are water soluble, that's 8 b vitamins and vitamin c, they must be aquired on a daily basis,a failure to do so leads to lower body functions.
Carrots don’t have any vitamin A actually. Carrots are a good source of beta carotene, which the body can then convert to vitamin A. This is why it’s very common to see vegans with vitamin A deficiencies. The active form of A (retinol) is just not found in plants.
Hence cod liver oil solution being part of my daily intake. I do feel the positive effects. I suspect all that Scott's emulsion my Mum fed me as a kid impacted my adulthood.
carrots don't contain vitamin a retinol but instead beta catotene. you would need to eat quite a few carrots to get the same amount in a spoon of butter. too much beta carotene can potentially suppress thyroid function. i knew a woman who was into carrot juicing which had literally turned her skin orange. the other thing to watch for are knowing what's in your supplements which largely compromises polyunsaturated fats usually the toxic soy oil and only minute amounts of retinol
When it comes to Vitamin A advice, most of what we hear is a bunch of warnings. It’s nice to hear the positive side of the story.

Heating is the largest vitamin A consumer but fortunatelly white fat tissues are either insulator. Immune system is also a large vitamin A consumer.
In adult people you can't measure vitamin A deficiency in the blood only in emergency case. But you can measure vitamin A deficiency in the blood of child because cortisol is working differently in childhood.
Cortisol turn off/lower body functions to save retinol for the brain but only supplementing with vitamin A won't restore we need the opposite hormone to restore.
The opposite hormone is vitamin D. Because vitamin D and cortisol hormons have the same properties but in the opposite way. e.g. Cortisol blocks calcium absorption and bone building.
Only natural forms of vitamin A are safe to take but only with vitamin D. Artificial forms are toxic. (e.g retinil-acetate is toxic for the liver because of water solubality).
Taking only vitamin A for long term period caused toxicity is in fact calcium deficiency problem according to symptomes => you need vitamin D and calcium (+magnesium).
And vitamin D toxicity is in fact vitamin A deficiency in the liver (very rare case) and in this case cortisol will spike above the vitamin D level and their interplay causes high calcium level and other problems. Your brain can't get enough vitamin A (energy) so you will have fatigue, anxiety, depression, etc...
Stress is a situation when brain need more energy...
Any resources or links to make sure those with renal insufficiency get enough vitamin A without causing issues?
Love all your content! So well disseminated
Right? I've heard that high vitamin A can effect the kidneys or liver adversely.. wish he had mentioned something about that
@@elyeyi369 totally! It’s so hard getting reliable info For CKD sufferers
I’ve been testing.
I was always told its very hard to overdose on these things from food sources. It's seems to be supplements 99% of the time that causes these issues.
Thank you Mike, much appreciated. Good support for me continuing with Cod liver oil. Especially during the northern winter months. Will forward to others.
Could you please share which brand of Cod liver oil you're using?!
Greatly appreciated 🙏
@@moniryousefian8782 Whole Foods 365 pill form.
Cod Liver oil has an incredible amount of Vitamin A and D. How much do you recommend taking?
Great Video. I’ve been focused on Vitamin D. It’s super to have this info as well!!
Thanks Mike!
Shirt choice on point
Vitamin A is needed by stem cells to differentiate into white blood cells (immune cells) and red blood cells.
Interesting... Assuming white cells are produced by default, this could explain how vitamin A deficiency might lead to an overactive immune system, as well as anemia. (I haven't researched this, yet -- just speculating!)
My story. One of my sons and I are not vexed. We got the virus. I had been taking vitamin D. C and zinc for many months prior. I've actually always taken vitamins. Our symptoms were relatively mild. My son who Is 25 symptoms were a little worse than mine. For example He had fatigue that I never experienced. In fact I carried on my days as I normally did.
We both got it again from my other fully vex and boosted son who got it from a fully vexed and boosted friend. My unvexed son and I had very mild symptoms. They were a nasal drip and scratchy throat. Pretty similar to our inital symptoms when we got it the first time. The symptoms never progressed and after approximately 48 hours we both felt completely fine.
My vexed son wasn't as lucky. While his symptoms were relatively mild they were worse than ours and lasted about a week.
Im curing an ear inflammation/infection of several months stubborn standing, with Vit A, 4 tiny pills twice a day, cod liver oil. first dose one evening, the next morning I could already feel a good difference. I also take Vid D and zinc every day or every 2nd day, but the inflammation/infection refused to give way UNTIL i took Vit A.
Thank you for your great reports
You are right Vitamins A and D are essential to reinforce our immune system🦠 ; some of my favourite whole foods: liver, salmon, eggs, broccoli (too many to list here); use to supplement with CLO however, was afraid of getting too much due to consuming whole foods; however, if one doesn’t get enough thought, it’s a very good idea to supplement; thank you.
Thank you for this
Great info, appreciate it
Thank you!
From what I read, Accutane (high doses of Retinol) was first developed as a drug for chemotherapy and later turned out to be helpful with acne.
The side effects of Vitamin A toxicity from Accutane is not good. I took that drug and regretted it. I suffered from dry eyes, mouth, and skin for over 5 years. All I had to do was simply change my diet and cut out all processed junk foods. It has taken me many years to finally get back to normal. The carnivore diet also helped me out a lot and has kept my severe cystic acne from coming back.
@@BiggieCheese45 I didn't have any major side effects and only stopped taking it after noticing my T levels dropping. Should have done keto/paleo from the beginning but too late now. My skin is much better than before though
@@bjoshua1980 I took Isotretinoin and went up as high as 50mg 3x a day for 2 months. It started at 10mg, 25mg, 40mg, and then 50mg. I took it for almost a year.
Is the Retin A face cream used in the body like a supplement would be?
thank you very much
Good stuff as always! Thank you Mike 😊
Sweet potato is a top vege source I just found out. Could help explain the Okinawans.
As always, great info. Thanks Mike.
Wow, really awesome content. Interesting! So do you think vit. A can help with allergie against pollen as well? Greetings from Sweden
I’ve been searching for the optimal amounts of vitamin A to consume daily and all I can find is the RDA. We know rda are not optimal levels. Do you know of any studies that have researched the optimal levels?
I think the best thing is to take vitamin A along with D and K2.
They work in synergy and by increasing the dose of vitamin D the doses of the others must also be increased.
The toxicity threshold of vitamin A is related to the presence or absence of D and vice versa.
To give an example, above a certain threshold zinc can also be toxic but if you add a little copper the toxicity disappears.
Probably above a certain dose the cofactors become essential to avoid problems, the RDAs are just numbers that do not take into account the interactions between the various nutrients.
We appreciate the knowledge...
Could you do a video on remedies for seasonal allergies? Such a widespread problem that seems to be very poorly understood / have few effective solutions.
I've been able to get over my seasonal allergy problems but I'm not sure if it was supplementing with Vitamin D, A or C that did it. FWIW my Vitamin D levels were low before supplementing.
Quercetin/ bromelain works for me with seasonal allergies. Start about April until the first freeze.
really cool explanation
Good one...
I have a BCOM1 gene mutation and was recommended Vitamin A as a therapeutic treatment. BCOM1 converts beta carotene into retinol. FYI I have Hashimoto's thyroiditis, an autoimmune condition that destroys the thyroid, so very relevant info in this video, thanks!
How much vitamin A should we take per day? In supplement form?
Carlson Cod Liver Oil is working for me and..a natural lemon flavor. A good amount of E also.
The Vitamin E in there is more of a preservative BTW. But I hear you
@@Highintensityhealth I use Rosita
Just discovered your channel but this my second video and I'm impressed with your content! Keep up the good work!
On a separate note: I would like to know your thoughts on Eric Berg? I'm a big fan of his content.
The carotene compounds are bio similar but is NOT vitamin A
Does anyone know why I get really bad muscle pain and dry eyes when I take Vitamin D3 supplement? My Vitamin D level is only 13. Doctor recommended to take 2,000 IU, but I can not tolerate even 1,000 IU. I have tried one that comes with K2. My doctor has no idea.....I'll get cancer from lack of Vitamin D someday....qq
Thank you
Love the statement “virus” with that little picture of Dr Fauci in the bottom corner. Just too perfect
Thanks for sharing this!
I guess a man of your curious investigative incline, has already seen the Dr greegor nutrition facts video on supplementing vitamin A and concomitant deficiency there of....
We should be supplementing and your the qualified one to tell us the best way to supplement....
I look forward to your future videos .
Great video Mike, I really like the info you share. Health is important.
Small request, please don't forget to mention how important it is to take Vitamin K along with Vitamin D.
So what is the correct ratio of A to D?
I love liver! Thanks to my grandmother always cooking it when I was a child and she would get it cut thick like steak from butchers
I have chronic sinuses and I haven't had a problem in years however since I started taking vitamin a my sinuses have, anyone know why ?
I've had a similar experience. Last year started taking vitamin a then after about 2 months broke out with psoriasis (never had it before) and sinus problems. My eyesight has gone worse too. I've been hearing lots of conflicting information regarding vit a. Dr Garrett Smith seems to think it can become overloaded quite easily and suggests detoxing from it. On the other hand Dr Chris Masterjohn seems to think you can go full send as long as you pair it with adequate vit d.
Not sure which to believe as they both have complelling arguments.
I still have the psoriasis and have noticed having cod liver oil or liver makes it worse about 2 days after. Never used to have any issues with either before that short stint of supplementing vit a.
Thank you Mike !!! Great infi
i know there's something in vitamin A for immunity after i finished my accutane. Before im having terrible cough almost 3times each year. During my low dose course, i didn't have any coughing episode or got Covid... 4 months after finishing accutane i got Covid and productive coughs came back again
Keep on trucking
*How much beef liver should you eat daily?* Can too much vitamin A cause hair loss?

Great info! 👍
I've heard U can take up to 500,000 IU for a couple of days if U R sick! And over a 120lbs but know the right type I use 'Carlson's" definitely stay away from synthetic Vit A
Hello Mike!
There is no plant that contains vitamin a, carrots contain beta carotin, not vitamin a.
Thank you, should have mentioned pro-vitamin A.
Which is badly or even not converted into Vit A by some people !
So cucumbers are higher in Vit A or carrots?
@@BankerSinbad Neither. Carotenoids are not Vita A. They are pro-vitamin, a precursor. Very little as low as 2-3%, if any, actually gets converted in the gut. Amount varies from person to person. Better to get the real forms from fat sources. It's a fat soluble nutrient after all
@@JYAN2852 bro you won't believe, a 48 year old was hospitalised due to Hypervitaminosis A, because he use to eat 5-6 pounds carrots a week... What would you say now?
Vitamin A maintains external cell membranes and surface glycoproteins and cell differentiation deficiency is linked to thymic lymphocytes increased severity of bacterial and viral infections
whats the fresh cod liver place you mentioned? im also in the pnw and would love to try it. HATE BEEF LIVER!
Do you have a video on the whole vitamin A toxicity debate?
Dr. Garrett Smith is the guy you need. He did extensive research on how toxic Vitamin A is, how your liver accumulates it over the years and gives you health problems. It’s not even a vitamin, but a toxin.
Recommended vitamin A preferably in liquid. I have hypothyroidism with a goiter.
Actually, there are 13 vitamins,9 of them are water soluble, that's 8 b vitamins and vitamin c, they must be aquired on a daily basis,a failure to do so leads to lower body functions.
Ty.
Mike, could you point me to a good resource as to the ways ample beta carotene does not provide the same benefits? Thanks for the video.
Carrots don’t have any vitamin A actually. Carrots are a good source of beta carotene, which the body can then convert to vitamin A. This is why it’s very common to see vegans with vitamin A deficiencies. The active form of A (retinol) is just not found in plants.
Far far far more important than vitamin D! Problem: it is condemned because people usually use the synthetic forms. Do not use the synthetic forms.
Good point Amanda!
Thank you for these very informative vedios!!! I will start taking vitamin A alpng with my vitamin D. Maybe my immune issues will be lessened!!!
Hence cod liver oil solution being part of my daily intake. I do feel the positive effects. I suspect all that Scott's emulsion my Mum fed me as a kid impacted my adulthood.
carrots don't contain vitamin a retinol but instead beta catotene. you would need to eat quite a few carrots to get the same amount in a spoon of butter. too much beta carotene can potentially suppress thyroid function. i knew a woman who was into carrot juicing which had literally turned her skin orange. the other thing to watch for are knowing what's in your supplements which largely compromises polyunsaturated fats usually the toxic soy oil and only minute amounts of retinol
Mango and papaya for vitamin A! Fruit is healthy!
Good to know!❤
Thank you for the video. What is your favorite way to get Vitamin A?
