Vitamin A for oil enrichment. Contraindications for oil solutions of vitamins a and e. Contraindications and possible side effects when taking vitamin A

Since ancient times, the best minds of mankind have studied the ability food products heal some human disease. It is known from ancient Egyptian medical treatises that the priests of the greatest civilization in the world possessed the secret of treating night blindness (impaired vision at dusk) with the help of the liver of animals and fish, without knowing A.

In butter, sour cream, egg yolk and other products, this unique substance will be found much later.

A bit of history...

At the turn of the XIX-XX centuries, active work began on the study of special, vital important elements and compounds that help maintain health and prolong human life. Among the researchers were the Russian biochemist N. I. Lunin, the Dutch bacteriologist Christian Eikman, the English biochemist Frederick Hopkins and many other Russian and foreign scientists. In 1911, the first Polish researcher Kazimir Funk found a cure for severe nervous disease beriberi, which occurs against the background of a deficiency of crystals isolated from rice bran, he called "Vitamin" or Vitamine. Translated from lat. vita - means "life", and from English. mine - "amine", which made it possible to classify this drug as a nitrogen-containing compound. The scientist also suggested that many ailments arise due to a lack of certain substances in the body. This marked the beginning of a whole era of discoveries, the first of which was the production of vitamin A or retinol.

In 1913, two independent groups of scientists (the first included Elmer Werner McCollum and Marguerite Davis, and the second Thomas Osborne and colleagues) extracted from butter and chicken yolk a substance that does not dissolve in water, but behaves well in lipids. It was called "fat-soluble factor A", renaming Funk's famous "vitamin" to "water-soluble factor B". Thus, the basis of the science of vitamins was created - vitaminology, the "pioneer" of which was retinol.

Retinol in oil is intended for topical and internal use.

Retinol on oil based is a clear liquid, bad smell and taste.

The color can be from light yellow to dark yellow. Vitamin preparation released in pharmacies without a prescription. But, despite this, it should be taken only as directed by a doctor.

Vitamin A in any form of release has a positive effect on the body. Without this biologically active compound, the exchange of organic substances is impossible. The role of the component is also great for the exchange of minerals.

Retinol is responsible for the health of the skin and mucous membranes, prevents the formation of cholesterol. In case of insufficiency, the ability to adapt to conditions is impaired. poor lighting. Based on this fact, one can judge the importance of vitamin A for the functioning of the organs of vision.

The main indication for the use of oil-based retinol is its absence or shortage in the body. In ophthalmology, vitamin A is actively used to treat eye diseases: retinitis pigmentosa, xerophthalmia, eczematous lesions of the eyelids and other pathologies.

Since retinol is important for skin health. it is used to treat skin diseases, recovery after burns, frostbite. Retinol is also effective in the fight against acute respiratory infections and diseases of the upper respiratory tract.

Outdoor use

For frostbite and burns, the oil solution is applied topically. It is applied to the affected area after cleaning. After lubrication with the agent, gauze must be applied. The procedure at the beginning of treatment is repeated 5-6 times a day. As the scar forms and heals, the frequency of lubrication is reduced to 1 time.

Vitamin A prevents skin aging. Once in cosmetic practice, vitamin was used only as an anti-acne remedy. But the anti-aging properties of the component were discovered. Based on this, cosmetics companies began to produce creams with vitamin A. Tocopherol acetate in pure form oxidizes quickly. Now in production cosmetics its molecules are placed inside a liquid crystal.

With age, the synthesis of collagen and elastin slows down. As a result, skin cells die. It will take 28 days to fully update them. Retinol speeds up this process. small capillaries strengthened, blood circulation improves.

The vitamin is also good for hair. It makes them elastic and smooth. With topical application of preparations containing retinol, the condition of the nails improves.

How does retinol interact with other substances?

At joint application preparations with calcium, the effect of the use of the mineral is weakened. The risk of developing hypercalcemia increases. Mineral oils, neomycin, colestipol reduce the absorption of retinol.

oral hormonal contraceptives contribute to an increase in the concentration of vitamin in the blood. Increased chance of developing intracranial hypertension with simultaneous use antibacterial drugs groups of tetracyclines.

Tocopherol reduces toxicity and prevents the deposition of vitamin A in the liver. But high doses of the "vitamin of youth" can reduce the amount of retinol in the body. With zinc deficiency, the component does not turn into a biologically active form.

The most effective is the simultaneous internal and external use of vitamin A. If side effects appear, it is recommended to stop using the funds. Periodic application of retinol to the skin and hair is the way to beauty and health!

• Which solution of vitamin A in oil to prefer - retinol acetate or retinol palmitate, and whether one of them is really poorly absorbed by the body;
• With what problems and diseases, vitamin A preparations can greatly help our body;
• How vitamin A oil solution can significantly improve the condition of skin, hair and nails, and about what important nuance you should know when using the drug externally;
• What dosages are the norm, and which ones are critically high;
• Names of preparations with a solution of vitamin A, specially intended for cosmetic use;
• And also find out in which cases it is better not to use an oil solution of vitamin A at all ...

Generally speaking, the main form of vitamin A preparations is liquid solution in oil. Another thing is that this solution can be packaged in different ways: in small glass vials, gelatin capsules or even glass ampoules.

And here aqueous solutions Vitamin A - retinol acetate or retinol palmitate - you will not find on sale, because these compounds are among the so-called fat-soluble substances, and do not dissolve in water.

On a note

Accordingly, it makes no sense to try to dissolve an oily solution of vitamin A in a glass of water - droplets of the drug will simply float to the surface of the solution and will not dissolve.

Vitamin A in oil is used in in large numbers therapeutic situations, and it is used both internally and externally.

As a rule, oil solutions of retinol acetate and palmitate are commercially available in 10, 20 and 50 ml bottles. Usually in such a solution, vitamin A is contained in the form of retinol acetate, less often in the form of palmitate.

A natural question may arise: what, in fact, is better - retinol acetate or palmitate? Is there any significant difference in their properties and are these different ones of the same benefit? chemical structure and the composition of the substance is carried to the body?

So: when it enters the body, both of these compounds are cleaved with the release of the same active substance(retinol). Therefore, both retinol acetate and retinol palmitate are used in medicine as equivalent drugs, although the dosages required to obtain the same amount active substance, will differ:

• 1 milligram of retinol acetate corresponds to 2907 IU of vitamin A;
• 1 milligram of retinol palmitate corresponds to 1817 IU of vitamin A.

This is interesting

Retinol acetate was originally produced for the needs of veterinary medicine, and palmitate - specifically for public health. However, the production of retinol palmitate is more expensive and, accordingly, less profitable, therefore, preparations in the form of acetate are more often on sale. For the end consumer, there is not much difference, although there is a common misconception that, they say, retinol acetate is an inactive form and is almost not absorbed by the body, while palmitate is maximally active. Actually this is a myth.

Properties and indications for the use of vitamin A oil solution

Vitamin A in oil has the same effect on the human body as natural sources of this beneficial substance. In this case, the oil plays only the role of a more or less inert carrier for the dissolved vitamin.

So, retinol takes part in a number of important biochemical processes and body functions:

• Reliable functioning of the immune system - vitamin A not only inhibits the activity of free radicals and has an antioxidant effect, but also stimulates the synthesis of immune system cells;
• The work of the organs of vision. Vitamin A is necessary for the synthesis of the rhodopsin pigment contained in the photosensitive cells of the retina of the eye (with a lack of vitamin A, the inability to see at dusk develops - night blindness). In addition, retinol protects the eyes from the development of such serious illnesses like cataracts and macular degeneration;
• Regulation of metabolism - vitamin A is involved in the synthesis of proteins and hormones in the body, as well as in some energy reactions;
• Formation and growth of the skeleton, support for the musculoskeletal system as a whole;
• Production of hormones and maintenance of spermatogenesis in men;
• Protection blood vessels from cholesterol deposits.

Given the above properties of vitamin A, it becomes clear why taking its oily solution is often prescribed for treatment and prevention in the following cases:

• eye diseases;
• weakened immunity (both seasonal or chronic, and caused by any disease);
• disorders in the development of the skeleton in children;
• atherosclerosis and other arterial diseases;
• skin diseases, including such serious ones as dermatoses, ichthyosis and red hair lichen;
• disorders digestive tract;
• consequences of drug addiction and alcoholism;
• depression and some diseases of the nervous system.

Vitamin A is also sometimes prescribed for multiple pregnancy. Its use in cosmetology is no less known - let's look at this point in more detail.

Vitamin A solution in cosmetology

IN cosmetic purposes vitamin A oil solution is very convenient to use. Today, capsules with a liquid solution of vitamin A inside are also widely used for these purposes - they are pierced with a needle to extract the solution.

For example, liquid vitamin And in oil it is used:

• As part of shampoos to strengthen hair and improve the scalp (retinol provides normalization metabolic processes and improved hair nutrition). To do this, a solution of vitamin A is simply added to any shampoo;
• As a component of various masks - both for the face and for the head: vitamin A improves skin nutrition, softens it, eliminates fine wrinkles, and ensures overall tenderness and softness of the skin. In addition, due to the antioxidant activity, retinol provides prevention of the development age spots and coarsening of the skin from exposure to ultraviolet rays;
• In homemade lotions and creams for the skin of all parts of the body;
• And also an oil solution of vitamin A is contained in many well-known cosmetics from famous brands - Nivea, BIOMATRIX, Klapp, BeautyMed, etc.

However, it should be borne in mind that all methods of external use of vitamin A in cosmetology have one main disadvantage - the low absorption of retinol with this use. The best route for retinol to enter the body is through the stomach. But through the skin, even with diligent rubbing, only a tiny amount of a useful substance penetrates into the cells, and one cannot count on a pronounced healing and protective effect from such an amount.

Thus, in most cases, much more pronounced effect can be obtained by taking vitamin A preparations orally in combination with local external application.

On a note

If you want to improve the condition of your nails, then adjusting your diet to normalize your vitamin A intake or using a vitamin A preparation in oil will be much more beneficial. the best option than just smearing nails from the surface with various homemade creams and masks. The ideal structure of the nail should be formed directly at the time of growth of its cells.

In addition, at serious problems with nails, skin or hair, it is very useful to first consult a doctor, since the cause of the problem can be far from only a lack of any vitamin.

It is important to remember: no matter for what purpose vitamin A in oil is purchased, it is always useful to consult a doctor before using it. Retinol preparations have their own contraindications, and their independent thoughtless use can be fraught with very unpleasant consequences.

Retinol acetate and the rules for its use

Today, in pharmacies, retinol acetate is most often available in either 10-ml bottles or 50-ml bottles. The drug is produced by many companies and vitamin factories: Russian Polisintez and Polisan, Ukrainian Technolog and Kiev Vitamin Factory, as well as many European enterprises. At the same time, regardless of the manufacturer, the composition of the preparations is almost the same, and the difference between them lies only in solvents - different vegetable oils can play its role.

On a note

Accordingly, if you are allergic to the drug, you can sometimes try to find retinol acetate on sale from another manufacturer - in some cases this solves the problem.

The daily dose of retinol acetate oil solution depends on the specific medical case.

The daily requirement for retinol in an adult is 3000 IU. 1 ml of a 3.44% solution of retinol acetate contains 100,000 IU of the active substance. One drop of this solution contains approximately 3000 IU of the vitamin and can be recommended for prophylactic administration once a day.

For treatment various diseases doses and the schedule of taking the drug are prescribed only by a doctor. In the treatment of particularly complex eye diseases and some dermatoses, up to 100,000 IU daily are prescribed, but with such therapy, the course of treatment should be constantly monitored by a specialist.

average price for a 10-ml bottle of retinol acetate today, depending on the manufacturer and method of implementation, from 30 to 50 rubles.

“Six months ago I started adding vitamin A to masks. At first I fooled around with capsules, then I just bought a bottle and started pouring from it. It's called retinol acetate. With it, the skin condition is definitely getting better: it has become softer, cleaner, does not get oily so quickly. For six months, I noticed that several age spots on my cheeks had gone, fine wrinkles seemed to straighten slightly ... "

Svetlana, Posad-Pokrovskoye
