Liver is not only the richest source of ready vitamin A, but it is also a true nutrient bomb.

Steamed beets and pumpkins are also great sources of vitamin A (via carotenes), which also contain many other useful nutrients.

It is better to cover our vitamin A need from these, than to replace it.

Unfortunately many do not like or try to avoid liver, but in the meantime they do not prefer the consumption of carrots/pumpkins.

 Our product is recommended to them, mainly if thy also take vitamin D3. We recommend the same amount, or maximum twice as much IU vitamin A replenishment, than the consumed IU of D3.

We recommend taking 1 to 10 drops a day, depending on the vitamin A content of our nutrition and our vitamin D3 intake.

Scientific background

It’s probably the simplest product one could imagine, still it had to be conceived, as for many it can be a great deal of help in setting the optimal retinol : D3 ratio.

Dissolved in plain and simple retinol-palmitate MCT oil, stabilized with a bit of natural vitamin E complex.

Why retinol palmitate? (Retinol palmitate = retinyl palmitate, the latter is more correct)


Retinol is the ready form of vitamin A very well utilized by all, as it does not need to be converted by the human organism. Retinyl palmitate is virtually the only form retinol is found in food (liver), which is none other than a natural compound of the fatty acid found in the body (palmitic acid) and retinol. 90 % of vitamin A in the human and animal body is stored in the liver almost exclusively in the form of retinyl palmitate (a small quantity also in other form related to fatty acids).  The point is that nearly all vitamin A we can intake with food is retinyl palmitate.

Since, as a result of replenishing vitamin A in an organism already poor in vitamin D3, the ratio of A and D3 shifts abnormally toward vitamin A, additional vitamin A replenishment may further worsen the severe lack of D3, so based on multiple analyses, it may have adverse impacts. Replenished together with D3, on the other hand, it’s OK, and even an extreme dose of retinol is safe. Interestingly, however, in a 2003 analysis (metaanalysis), where all the former analyses of vitamin A replenishment were analyzed, the conclusion was made that neither vitamin A coming from the liver (which is retinyl palmitate) nor the retinyl palmitate replenished solved in oil, only the dry form of retinol (retinol acetate), or water soluble or emulsified forms of retinol cause any kind of non-desired impact. There is no way to know exactly, what the reason for this is, but considering the fact that from the different forms of retinol only retinyl palmitate is natural, it’s not so surprising... This is why we selected retinyl palmitate and solved it in MCT oil.

Regardless to this, excessive retinyl palmitate replenishment is also dangerous, as its ratio compared to D3 can be displaced with it but it’s important anyway, to obtain retinol only from natural food and/or by consuming retinyl palmitate, and to avoid retinol acetate and all water soluble, emulsified or liposomal forms, which on the basis of the referred analyses represent higher risk.


The optimal retinol : D3 ratio (expressed in IU)

Today, hardly anyone can be capable of telling the optimal ratio of vitamins A and D3, however some important findings can be made:

  • A/D3 ratio below 1:1 (meaning that more D3 is taken in) is not a problem, at least to a certain level. There is a number of analyses, where the replenishment of at least 10 thousand IU vitamin D3 is beneficial without any kind of negative impact, also on long term. In the latest study, nearly 5 thousand people were followed, who ingested 5 thousand, 10 thousand or 20 thousand IU D3 on daily basis, without anything else. Even among those taking daily 20 thousand IU D3 for 7 years - and among no one else - no negative change were observed, either in the blood count or in the blood calcium level (which is practically considered as the only side effect of D3 - by unfounded fear as it turns out).  On the contrary, a number of positive changes happened in their condition/blood count. As most people typically consume less that 5 thousand IU of vitamin A (also considering carotenoids), so the ratio is apparently not problematic up to 4:1 (at least not in retinol efficient condition, with high-dosage D3 replenishment).
  • Ratio exceeding 10:1 (where retinol is 10) can already be problematic. At least in an analysis, where 72 nurses were followed, it was revealed that those, whose retinol intake was at least 10 thousand IU (about half of which came from food, and the other half from replenishment), 48% more suffered pelvic bone fracture, than those consuming only 3000 IU vitamin A (largely coming from carrots, i.e. carotene). As D3 intake of people is around 500-2000 IU, even if they consume some kind of multivitamin or sunbathing at times, in case of the group with bone fracture, this ratio could have been between 10:1 and 40:1. So, up to 10:1 ratio it seems to be safe (at least in mild D3 deficient condition).
  • This is going to be even more theoretic: From evolutionary point of view, the ratio seems to be optimal around 1:1, as in case of people, who got used to regular sunbathing, D3 generation of the skin is set to the synthesis of around 4 thousand IU per day, meaning that our African ancestors obtained around 4000 IU D3 on daily basis. For approximately 3 million years, man’s predecessors were basically collectors and carnivores: they animal food included marrow, brain, bone, insects, mollusks, ocean scurvy / algae / seaweed and of course fruits / vegetables / tubers. Liver is a preferred part of the prey for the predators (unlike people, predator animals are capable of emptying retinol, they are unable to overdose it).   Man, on the other hand, started hunting only 100-200 thousand years ago, but if we count the share of calories an animal’s liver+kidneys give from the volume that can be gained from eating the entire animal, then we come to the conclusion that with the daily intake of 2 to 3 thousand calories, if we eat an animal “nose-to-tail”, we can get approximately 2000 IU retinol per day (besides liver and kidneys, no part of animals contain any significant amount of retinol).  For the 1.1 ratio 4000 IU retinol would be necessary, but as vegetable food also contains  carotenoids, which can convert into retinol, it was OK to be above 1:1 ratio (with more vitamin A). On the other hand, considering pre-formed, ready vitamin A (retinol), the 1:1 ration was not really attainable, let alone being exceeded, only if we’d have thrown out most of our animal food, and hunted animals mainly for their liver only... Hardly...


Those, who are interested in the topic more deeply, I recommend Gábor Szendi’s book called Új vitaminforradalom (A new vitamin revolution), or the book of Paul Jaminet called  Tökéletes    Egészség (Perfect Health)  című    könyvét, and the related paper of the Weston Price Foundation: tion/vitamin-a-on-trial-does-vitamin-a-cause-osteoporosis/

So, as I see it in summary, one should strive to 1:1 retinol :   D3 ratio, not counting the intake of carotenoids, but also ingesting plenty of them to ensure that if more retinol is needed, it can be converted from carotene.   And the ration between 1:4 and 10:1 is probably also good, especially if our vitamin K intake (K1+K2) is in order. For example, vitamin K counteracts excessive adverse impacts of D3 also without vitamin A. Not only they prevent each other’s side effects, but also help each other’s beneficial impacts.


Practical recommendations


Liver is by far the best source of retinol.   Kidneys also contain a significant amount of retinol, but far less, than the liver.  Retinol contents of other food products is negligible; egg yolk can be mentioned, but it isn’t worth considering, as we’ have to eat dozens of them on daily basis to ensure the daily minimum... Hardly anyone eats kidneys, let alone several times a week. So only liver is worth considering...

100 grams of liver contains approximately 20 thousand IU retinol (beef and chicken liver around 10 to 20 IU, goose and duck liver around 30 to 40 thousand IU, turkey liver 60 to 70 thousand IU, whereas cod liver around 100 IU).

100 grams carrot, on the other hand, not consumed raw, but with a little fat (e.g. stewed on a little coconut fat, butter or olives), gives about 5 to 15 thousand IU retinol, depending on one’s digestion (gall/absorption) and genetics (conversion from carotene into retinol).  As we cannot know, how good our organism is good at absorbing carotene and converting it into retinol, one should better calculate only 5 thousand IU for 100 grams carrots, or even less, if consuming it raw, without fat.

It is important that our body converts from carotenoids and utilizes only the retinol it needs (absorption and conversion increases in case of low retinol level, and decreases if the retinol level is normal). So, retinol cannot be overdosed using carotene.


Some examples:

If we almost never eat liver or carrots/pumpkins, then it is recommended to ingest about as much retinol as D3, or even a little more. If we consume a lot of carrots (e.g. half a kg every week), and also at least 100 to 200 grams of liver, then vitamin A is worth replenishing only in case, we consume very high amount of D3 (e.g. 8 to 10 thousand IU).

Replenishing 4000 IU D3 every day is 28 thousand IU per week, which means that the 1:1 ratio is already reached with about 100 to 200 grams of liver per week (or also in case of consuming 600 grams of carrot per week, or e.g. weekly 100 grams of liver + 300 grams of carrots.).

Replenishment of daily 10 thousand IU D3 is 70 thousand IU per week. For this we would have to eat as much as nearly half a kg liver or one and a half kg carrot every week (or e.g. 250 grams liver + 750 grams carrot per week).

It is sufficient to consume retinol on weekly or even biweekly basis, you don’t have to eat it every day.  What is important is that during a set time period  (e.g. in one week) one should intake at least as much retinol as D3, expressed in International Units (IU). A little more is not a problem, regarding that problems begin only when the retinol level is 10 times of the D3 level (for an average man, the A:D3 ratio is well above 10:1).

If don’t like or would want to calculate all the time, then I recommend to replenish equal amounts of retinol and D3, which means that the replenishment itself should also be at 1:1 ratio as in case of 1:1 replenishment ratio we will not reach the potentially risky 10:1 ratio even by eating liver all the time… (in addition to daily 4 thousand IU D3 + 4000 IU retinol intake, we’d have to consume 1 kg liver per week to reach the 10:1 ratio). So, if one consumes liver only a couple of times per week, I recommend 1:1 replenishment. To those eating liver more than twice a week I recommend counting - whether they like to or not - their weekly retinol and D3 intake, and try to set it between ratios 1:1 and 3:1...

Gyakori kérdések
Milyen ellenjavallatai vannak a termék fogyasztásának?

A termék mindenki számára biztonsággal fogyasztható.

Milyen arányban javasolt fogyasztani az A és D-vitamint?

Minimum ugyanannyi A-vitamint javaslunk pótolni, vagy étrendi forrásokkal bevinni azt (pl. gyakori májfogyasztás), mint amennyi D-vitamint szedünk. Az ajánlott adagolásról a „Tudományos háttér” fülön, az utolsó bekezdésében gyakorlati tanácsokat is talál.

Hogyan javasolt bevenni a cseppeket?

Célszerű egy kiskanálba csepegtetni, de ha tükör előtt a nyelve alá cseppenti az is jó megoldás, csak arra fontos ügyelni, hogy ne érjen a pipetta a nyelvéhez, mert akkor baktériumok juthatnak az üvegbe és megromlik a termék.

Nem ajánljuk az olajos cseppek folyadékba keverését sem (A-vitamin, E-vitamin, D-vitamin, K-komplex), mert a pohár falára tapad, és így egy jelentős része kárba veszhet.
