Vitamin A is popular among people who want to quickly restore their appearance and well-being. Retinol acetate capsules with instructions for use are available in every pharmacy. However, one should not independently conclude about the lack of this substance - perhaps health problems are caused by other reasons. An experienced therapist or pediatrician will help you figure this out, which you will need to contact before using the medicine.
general information
After reading the instructions for use, the composition of the retinol acetate capsules becomes clear - this is the same vitamin A that is ingested daily with food.
It was opened in 1913 and is indicated by the first letter of the alphabet. So the world became aware of a substance in which more than 500 chemical compounds were collected.
A person receives it from food of animal and vegetable origin, and in the first case, about 75% comes in, and in the second - only 25%.
The substance is contained in the following products:
- fish oil;
- cod and beef liver;
- yolk;
- caviar;
- milk, cream;
- carrots;
- soy, peas;
- cauliflower;
- parsley;
- Spinach
- pepper;
- kelp;
- grapes;

- melon.
It performs the following functions in the body:
- Participates in protein synthesis.
- Strengthens the immune system, protects against infections.
- Responsible for visual acuity.
- It takes an active part in the formation of bone tissue.
- Slows down the aging process.
- It affects the metabolism.
It has long been proven that people who include vitamin A-rich foods on a daily basis look younger. This is confirmed by numerous reviews.
What conditions are necessary for the absorption of vitamin A
Based on chemical characteristics, effective treatment or prevention is observed while taking with fats, so most dosage forms of the substance contain vegetable oils.
However, this is not enough. For optimal assimilation, a person should regularly receive with food:
- vitamins E, D, B;
- acids;
- calcium;
- zinc;
- phosphorus.
According to experts, in patients who had a clear vitamin deficiency, this condition was provoked by malnutrition and all kinds of diets. After taking retinol (in the dosage prescribed by the doctor), everything quickly returned to normal. Moreover, the positive effect, according to reviews, was noticeable a week after the start of treatment.
What happens when retinol is deficient
Such a problem is not uncommon at present. Vitamin A deficiency can occur in people of any age and gender, but most often it affects women, especially pregnant or breastfeeding. In second place are people of advanced age.
Lack of substance can be manifested by the following symptoms:

- brittle hair and nails;
- dull complexion;
- metabolic slowdown;
- dry skin and eyes;
- low hemoglobin;
- the appearance of cracks in the corners of the mouth;
- peeling;
- dandruff, oily shine of hair.
In young children, there may be a delay in mental and physical development.
It turns out that a lack of vitamin causes disturbances in the activity of many systems. Most deficits affect vision, reproductive function, growth and development (in babies).
However, all of the above symptoms can be the cause of other diseases, sometimes very serious, so when they occur, you need to consult a doctor, and not run to the nearest pharmacy for a miracle cure.
Most people who use Vitamin A in capsules claim that after a course of retinol therapy their appearance really improves. The skin becomes toned and silky, wrinkles are less noticeable.

Often, vitamin is used as part of complex therapy for the treatment of ophthalmic diseases, eliminating problems with the skin and other problems, the cause of which is not associated with a lack of substance. But in recent studies, the effectiveness of such treatment has not been identified. Nevertheless, people suffering from various visual impairments nevertheless noticed a slight improvement.

Overdose and side effects
The use of retinol acetate capsules according to the instructions or in accordance with the recommendations of a doctor should not cause negative consequences.
Some pain may be felt during the injection.
It is highly recommended not to exceed the recommended drug standards, because retinol tends to accumulate in the body and have a toxic effect on it for a long time.
Hypervitaminosis can manifest itself with such vivid symptoms:

According to the instructions for use, capsules of retinol acetate are not prescribed for children under 7 years of age.
Severe conditions require treatment in a hospital, where, under round-the-clock supervision of specialists, a series of measures will be taken to eliminate the symptomatic manifestations. Additionally, they are prescribed ascorbic acid and thyroxine, which are antidotes.
How to apply
The dosage is selected taking into account the indications at which retinol acetate capsules are prescribed. Instructions for use provide the following therapeutic regimen:
- For adults. For the prevention of 33,000 IU per day, for the treatment of skin diseases - 50,000-100,000 IU.
- To the children. In the first case, 1 000-5 000 IU, in the second - 5 000-20 000 IU.
For other pathologies, the amount of retinol acetate is selected individually.
Release forms and storage conditions
Many foreign and domestic pharmaceutical companies produce the vitamin under consideration (retinol acetate) in capsules. Instructions for use with each drug may vary slightly.
Vitamins are sold in gelatin capsules, injection solutions and coated tablets.
Dosage may vary significantly (33,000, 50,000, 100,000 IU). The selection of such a drug should be carried out by the attending physician.
You can buy medicine without a prescription. Store for two years in a dark, dry place, at a temperature of 4 to 15 degrees Celsius.
These vitamins must be hidden from children, because an overdose is extremely dangerous for the body.
Use in cosmetology
In addition to oral and intramuscular administration, there are many cosmetic recipes for improving the condition of the skin, hair, eyelashes and nails based on capsules of retinol acetate 33000. Instructions for use, however, do not describe this possibility. But women are increasingly resorting to funds that contain vitamin A. They can be all kinds of:
- creams;
- masks;
- peelings;
- baths;
- shampoos, etc.
As patients assure, the result of such an application is noticeable immediately after the first procedure.
But, according to experts, the use of this substance is externally unjustified, therefore there is no particular difference when choosing a dosage (33,000, 50,000, 100,000 IU). After all, when applied to the skin, the substance reaches the problem areas in a minimal concentration or is completely useless. In denial of all the positive reviews about such events, doctors and cosmetologists unanimously reiterate that the improvement in appearance comes due to the effects of vegetable oils, which is part of the composition, and nothing more.
A much better effect, they said, can be obtained by taking the vitamin inside. If the problem was precisely its lack, then after a while, a significant improvement in appearance and well-being can be noted.
If the expected effect did not follow, most likely the problem lies elsewhere. Then further actions will need to be discussed with your doctor. Taking drugs from this group yourself can seriously harm your health.
After reading the instructions for use of retinol acetate capsules, reviews of which are mostly positive, you can get a general idea about the drug. Vitamin A is an indispensable substance necessary for the normal functioning of the body. Its deficiency can lead to various diseases, but its excess is no less dangerous. For such treatment, a person should have clear indications, which were determined by the attending physician during the examination and after the examination.
