Vitamin A – why it is good for the body. Vitamin A benefits for humans


Vitamin A is not just on the first place in the general alphabetical list of vitamins: it participates in almost all the main functions of the body, helps to improve vision, strengthen the immune system. Vitamin A is also important for the skin. Let’s find out what functions Vitamin A performs, how to take it, and what contraindications exist for its use..

What is Vitamin A beneficial for the body?

Vitamin A regulates the process of protein production by the body, helps normalize metabolism, strengthens the immune system, effectively resists viral infections, and helps with wound healing. In addition, it makes the skin of women and men supple, smooth, and eliminates skin diseases. Retinol is also useful for vision, so people who spend a lot of time in front of the screen need to include it in their diet. For example, a product such as carrots will protect the mucous membrane of the eye from drying out and relieve you of the feeling of “sand” in your eyes. Retinol will also help you see better at night..

It must be present in the diet of infants and older children, because the components of the vitamin play an important role in the formation of bone tissues, joints and teeth, accelerating cell growth. Retinol also positively affects the functioning of the organs of the respiratory and digestive systems, therefore, for smokers, vitamin A is of particular importance.

For women’s health

Retinol is of great importance to women. Breast, consisting primarily of adipose tissue, is highly dependent on the balance of fat-soluble vitamins. One of them is retinol. The work of the cells responsible for lactation is regulated by chemical processes in the mammary glands. Numerous studies have shown that lactating and pregnant women need to take many additional vitamins, including retinol..

Why vitamin A helps, is for the spectacular appearance of a woman. Retinol is directly involved in the normalization of the lipid balance of the body. This component improves the condition of hair, nails, skin, improves vision and strengthens the immune system. Retinol is an ingredient in professional skin care creams – it makes it supple, supple, smoothes fine wrinkles. Retinol can be an excellent alternative to many cosmetics. At least reviews about the use of vitamin A for cosmetic purposes are entirely positive..

With a deficiency of vitamin A in the female body, girls lose weight, have problematic dry skin, they are concerned about bouts of depression, nausea, and sleep problems. The mucous membrane of the eyes with a deficiency of retinol is not sufficiently moistened, the eyes hurt. Subsequently, the development of cataracts. A lack of retinol can make it difficult for a woman to become pregnant, and the process of bearing will be difficult. The fetus will gain weight slowly; in the worst case, congenital malformations are possible. Finally, gynecological diseases may develop: cervical erosion, leukoplakia.

For children

A lack of vitamin in a child’s body can lead to progressive blindness, conjunctivitis, reduced resistance to infectious (including colds) diseases, their frequent complications in the form of pneumonia or bronchitis, growth retardation, and diseases of the digestive tract. A balanced diet and regular intake of vitamin A will help the body cope with such ailments. Retinol is useful for teeth and bones of newborns and young children – it accelerates their growth.

For weight loss

Vitamin A intake does not directly affect weight loss. On the other hand, experts recommend consuming the necessary dose of vitamin A inside for people involved in sports or fitness. Retinol accelerates metabolism, increases stamina and helps the body recover much faster from workout to workout. That is, you get the opportunity to engage more often and with maximum efficiency. And effective training will help to achieve quick results when losing weight, after which – to maintain the desired shape.

Why Vitamin A is useful in cosmetology

The benefits of vitamin A are not only the healing of the body from the inside, but also a positive effect on the condition of the skin, nails, hair. The widespread use of retinol by cosmetologists seems logical. The beneficial properties of vitamin A are known to millions of women who are trying to make their appearance impeccable and use it both for the skin of the face and for the heels (for example, for healing cracks). Let’s find out about the areas and features of the use of retinol in cosmetology.

Liquid vitamin for facial skin

Retinol has excellent effectiveness in the treatment of various skin ailments, improves skin condition. If there is not enough vitamin A in the body, wrinkles appear, the skin becomes dry, and the face looks unhealthy. Retinol in liquid form is used to treat:

  • Chronic form of dermatosis.
  • Psoriasis.
  • Eel.
  • Furunculosis.
  • Psoriasis.
  • Seborrheic eczema.
  • Inflammation of the oral mucosa.

Retinol has antioxidant properties, thanks to this the skin of the face becomes more resistant to sunlight and other adverse environmental factors. That is, liquid vitamin A preserves youth and makes you more attractive. This substance, which is included in the mask, helps smooth wrinkles in a natural way, improve blood circulation, and natural skin regeneration. Beauticians claim that retinol is a great alternative to much more expensive cosmetics, surpassing them in terms of effectiveness.

For eyelids and eyelashes

If you want to become the owner of beautiful, long, elastic and, most importantly, natural eyelashes, be sure to use products containing vitamin A. Retinol is needed for the synthesis of keratin – a substance that accelerates the growth of eyelashes, helps them recover faster in damage, increases their elasticity. We offer an effective cosmetic recipe: mix vitamin A with castor oil (1: 3 ratio) and apply the mixture to eyelashes every evening for 3-5 minutes. After this time, gently wipe them with a sponge.

The benefits of hair masks

Enrichment of hair with retinol, which is included in the composition of masks, helps to improve their condition. Thanks to retinol, curls are strengthened, become elastic, smooth, look healthy, alive. With a deficiency of this substance – brittle, dry, often fall out. To strengthen curls, you need to rub retinol and other useful vitamins with your fingertips into the hair roots or apply to their ends. Remember that masks should be applied to washed, slightly damp curls. The cap will provide more effective absorption of beneficial components.

For hands and nails

Spending a lot of time on facial skin care, women often make a mistake, forgetting about the skin of their hands. After all, she, too, is exposed to external influences (sharp fluctuations in temperature, ultraviolet, household chemicals), from which she begins to peel, dry out, crack, look groomed. The diet, work, general condition of the body have a great influence on the appearance of the skin of the hands..

Retinol is a natural component that helps to cope with the above problems. Note that it also has a positive effect on the nail plates, strengthening them, making them smoother, accelerating growth and preventing lamination. Eat plenty of fresh vegetables that are rich in retinol, and foods that are the source of animal proteins – dairy products, sea fish. Proteins provide the best absorption of retinol by the body. It is noteworthy that the growth rate of nails in vegetarians is very low.

We offer an effective method for hand skin care. Get oil solutions of vitamins A and E in the pharmacy and rub them regularly. In parallel, take retinol in capsules or tablets (without exceeding the permissible dosage). Beauticians recommend another method, based on the enrichment of conventional hand cream with retinol. This is not difficult to do: just pour the hand cream into a clean empty container, add the same oil solution, mix. Use as a regular cream.

How to take vitamin A in capsules

Taking vitamin A in capsules, it is important not to violate the dosage prescribed to you, because an excess of this substance in the body can be no less harmful than a lack of retinol. The average daily requirement for an adult in retinol is 1 mg, for a child from 400 to 800 mcg. Note that vitamin A is available in capsules with a content of 33,000, 50,000 or 100,000 IU (international units).

Interestingly, simply consuming capsules in the right amount is not enough to eliminate the deficiency of the body in vitamin A. You still need to know exactly how to use retinol. So, capsules should be drunk 2 times a day – in the morning and in the evening, and, exactly 10 minutes after the end of a meal. The reason is that just after such a time, the stomach removes components from the food that promote the absorption of vitamin A. Without them, retinol will not be effectively absorbed..

Contraindications to the use of retinol

Retinol, according to the instructions, is not recommended if you are diagnosed with gallstone disease, pancreatitis, and hypersensitivity to the substance. A contraindication is also the period of pregnancy, especially the first 3 months after fertilization. You should be careful for chronic diseases of the heart, kidneys. Other contraindications for taking retinol: cirrhosis, hepatitis. Be sure to observe the daily norm for children, the elderly, nursing mothers.

The interaction of vitamin A with other substances

Vitamin E is known to protect retinol from rapid oxidation in the intestines and body tissues. That is, if in your diet there are not enough products containing vitamin E, the body will not effectively absorb retinol. The output is a complex intake of both vitamins. A lack of zinc also disrupts the process of converting vitamin A into active ingredients. Moreover, there is an inverse relationship. That is, these substances are interconnected.

Mineral oils are able to dissolve fat-soluble components: then vitamin A passes through the intestine, but is not absorbed by its walls. Therefore, the regular use of mineral oils leads to a deficiency of retinol in the body, even if there is plenty of this substance in the foods you consume. The output will be a temporary rejection of mineral oils.

Finally, it should be noted that for the good absorption of retinol, the presence of a sufficient amount of fats and proteins in the daily diet is necessary. The body normally extracts vitamin A dissolved in dietary fats. It should be remembered that while taking retinol, alcoholic beverages should be excluded from your diet. Neglecting this rule is likely to damage the liver..

I work as a programmer, therefore, I have to spend 10-12 hours a day at the computer. For a long time, everything suited me, but a year ago I began to notice that my eyesight was rapidly deteriorating. It was hard to focus, my eyes hurt, I got a feeling of “sand in my eyes.” They advised me to increase the intake of products containing vitamin A. For several months in a row I eat 1 fresh carrot daily. Vision normalized, eyes get tired much less.

For a month, every other day, I applied retinol masks to my hair. The effect became noticeable after about a week and a half. Now my curls look healthy and beautiful, they are easy to comb and do not break. I recommend vitamin A to all girls who are faced with the problem of dryness and hair loss.

Katya, 28 years old

After several sessions of eyelash extensions, I encountered unpleasant consequences – my native eyelashes became thin, began to grow slowly, many fell out altogether. I tried a lot of cosmetics, spent a lot of money, but none of them helped like using the usual mixture of castor oil with retinol. Now my eyelashes look no worse than extensions!
