Ascorbic acid: benefits of vitamin C for humans. Can ascorbic acid cause harm, how not to overdo it with the dosage. Ascorbic acid in compounds. What are the benefits of vitamin C for children?

When scientists discovered ascorbic acid in the twenties of the last century, they had high hopes for the compound. And they were not mistaken. Vitamin C has brought a lot to humanity useful actions. And at the same time, almost no one knew what the risk of an overdose was.

After much research, it became clear that ascorbic acid is both beneficial and harmful to people. Let's find out what's what.

Why is ascorbic acid harmful?

Yes, yes, that’s what we used to call flat white tablets or round yellow dragees. Remember how coveted they were in childhood. And, having found the treasured bottle at home, who refused to gobble up several things at once? So how could we harm ourselves?

Ascorbic acid itself is harmless. Its overdose brings unpleasant consequences. And only when using a synthetic product (injections or tablets). Excess vitamin contained in vegetables and fruits is almost completely eliminated by the body.

So, harm ascorbic acid:

1. It greatly increases blood clotting. Therefore, there is a high risk of blocking all vessels with large and small blood clots. Who hasn't heard scary word thrombus?
2. Excess ascorbic acid causes severe pain in the stomach. Heartburn, pain, and nausea may occur. Because acid quickly eats away the walls of the stomach.
3. Promotes the formation of sand and stones in the kidneys. This is with regular overdose.
4. The functioning of the pancreas is disrupted.
5. An excess of ascorbic acid disrupts metabolism in pregnant women. And this is fraught unpleasant consequences for the unborn child. He may already be born with allergies.
6. May appear allergic reaction.

Who benefits from ascorbic acid?

However, despite all the unpleasant aspects described above, the beneficial properties of ascorbic acid are simply invaluable. Naturally, only a qualified specialist can accurately prescribe the dosage required for the correct effect.

So, the benefits of ascorbic acid:

1. Recovery. Vitamin C takes an active part in the synthesis of collagen fibers. Thanks to it, cuts and wounds heal faster. Bones also heal much better if you take ascorbic acid.
2. Hematopoiesis. No, of course not directly. But by helping the absorption of iron in the body, ascorbic acid is indirectly related to the synthesis of hemoglobin.
3. Boosting immunity. This is due to the fact that ascorbic acid helps the body produce antibodies. Therefore, vitamin C is the primary remedy for flu and colds.
4. Participation in metabolism. Ascorbic acid enhances the effect of essential vitamins (A, E), which allows you to bring your metabolism to an almost ideal state.
5. Cleansing blood vessels. Recently, everyone knows about the terrible cholesterol. But it is not scary for those who like to indulge in ascorbic acid. Vitamin C significantly strengthens the walls of blood vessels, making them strong and elastic. And, like a hard brush, it removes all plaques and blockages from the cardiovascular system.
6. Help with poisoning. Ascorbic acid has the ability to bind and remove free radicals from the body and heavy metals. Therefore, it is often prescribed for many types of food poisoning.

And, oddly enough, without ascorbic acid, all the cartilage in the body becomes fragile and crumbles. Remember what old heavy smokers look like. They're haggard appearance, plus it is very difficult for them to move.

This is because one smoked cigarette neutralizes about 25 mg of vitamin C in the human body. And without it, normal absorption of other vitamins and good job cartilaginous body of joints.

As you can see, the benefits of ascorbic acid in some cases are incomparably great. And harm often comes only from excessive use.

How to understand that you lack vitamin C

There are several external signs, by which it can be determined that there is an acute shortage of ascorbic acid in the human body. These include:

• constant pain in feet and heels
• general malaise similar to flu symptoms
• wounds and cuts do not heal for a long time
• pale skin
• strange anxiety and disturbing dreams
• wobbly teeth, bleeding gums
• general weakening of the immune system, tendency to colds

But it should be noted that only external signs are not enough. To make an accurate diagnosis, you need to contact a qualified specialist. Because the signs listed above may be symptoms serious illnesses, and not just a lack of vitamin C. And you certainly cannot self-medicate by simply eating ascorbic acid. In some cases vitamin supplement may not only be useless, but also cause even more harm.

Is it possible to take ascorbic acid with medications?

Some doctors are categorically against such a combination of drugs. And yet, the vast majority of doctors allow you to combine medications and ascorbic acid for simultaneous use. But, with a certain caveat. It is forbidden to take vitamin C with medications containing:

• folic acid
• iron
• caffeine
• B vitamins

More detailed information can always be found in the instructions for use of the drug.

What to do if a child has eaten a lot of ascorbic acid

Remember, at the beginning of the article, we recalled how in childhood we often tried to get our hands on the coveted bottle? What to do if your child succeeds?

Do not panic. Ascorbic acid is not poison. Therefore, without hysterics, you will scare the child. First, try flushing your baby's stomach. As usual - warm water and vomiting. After cleansing, give your child any adsorbent that is in home medicine cabinet. And make me drink more clean water. The first will absorb excess vitamin C, the second will help the body remove ascorbic acid residues. The most in the usual way- through the toilet.

Interesting facts about ascorbic acid

Did you know that you shouldn’t suddenly stop drinking vitamin C? It is necessary to gradually reduce the dosage so that the body learns to cope without the tablet form. Otherwise, you can provoke some unpleasant types of recoil from the body. For example, you may become susceptible to certain diseases.

By the way, many doctors around the world have recognized that regular intake of competent doses of ascorbic acid significantly reduces the risk of cancer. But it doesn’t completely rule it out.

Of course, ideally this vitamin should enter the human body with food. Then there will be no need for additional doses. But, who knows how to accurately calculate the dose based on currant berries or slices bell pepper? Besides, where can you get good fresh fruits and vegetables in winter? After all, they are the main natural source ascorbic acid.

No, canned and frozen will not work. They contain a negligible amount of vitamin C. Therefore, doctors strongly recommend taking pharmaceutical vitamin preparations at least in the cold season.

Now you know what role ascorbic acid plays in the human body. You also know the benefits and harms. Therefore, do not eat vitamin by the handful and do not stuff your children without the advice of a competent specialist.

If you delve into the history of ascorbic acid, its roots go back to 1928. It was invented only in its pure form, by the then famous scientist - chemist A. Szent-Gyorgyi. In 1932, he was able to explain to many why this acid is simply necessary for humanity.

Functions of ascorbic acid in the human body

The main function of ascorbic acid is antioxidant. With its help, the activity of free radicals is suppressed. This leads to proper control of oxidative and reduction reactions in the body. As a result, with the help of ascorbic acid, the walls of the body’s cells are protected from various kinds damage.

The benefits of vitamin C for each body system:

Harmful properties of ascorbic acid

If you take vitamin C long time in larger quantities than required, and then abruptly stop taking it, then the amount of this vitamin will be significantly less than it was before taking it. These consequences are associated only with the fact that if there is excess vitamin C in the body, a complete disruption of glucose absorption occurs. This threatens the appearance of the first signs of diabetes. There is also a risk of stones forming in the kidneys and bladder.

What is ascorbic acid?

What is ascorbic acid, benefits and harms, as well as what it has medicinal properties and what exactly is this vitamin good for human health? These questions often arise among those who care about their health, healthy image life and shows interest in traditional methods treatment. And this interest is understandable. Maybe in this article, to some extent, you can get an answer to these questions.

Perhaps the most ingenious invention of nature can be called vitamin C, also known as ascorbic acid. If gold medals were awarded at the Olympics held among nutrients, “ascorbic acid” would certainly rise to the highest step of the podium.

Vitamin C (ascorbic acid) is an organic compound with the formula C6H8O6.By physical properties This vitamin is a white crystalline powder with a sour taste. Easily soluble in water, soluble in alcohol. For the first time in pure form Vitamin C was isolated in 1928 by the Hungarian-American chemist Albert Szent-Györgyi, and in 1932 it was proven that the absence of this vitamin in human food causes scurvy.

Beneficial features:

Vitamin C is a powerful antioxidant. He plays important role in the regulation of redox processes, participates in the synthesis of collagen and procollagen, metabolism folic acid s and iron, as well as the synthesis of steroid hormones and catecholamines. Ascorbic acid also regulates blood clotting, normalizes capillary permeability, is necessary for hematopoiesis, and has anti-inflammatory and anti-allergic effects.

This vitamin is a factor in protecting the body from the effects of stress. Strengthens reparative processes, increases resistance to infections. Reduces the effects of various allergens. There are many theoretical and experimental prerequisites for the use of vitamin C for the purpose of prevention cancer diseases. It is known that cancer patients, due to the depletion of its reserves in the tissues, often develop symptoms of vitamin deficiency, which requires their additional administration.

There is evidence showing the preventive role of vitamin C against cancer of the colon, esophagus, Bladder and endometrium.

This vitamin improves the body's ability to absorb calcium and iron and remove toxic copper, lead and mercury.

It is important that in the presence of an adequate amount of vitamin C, the stability of vitamins B1, B2, A, E, pantothenic and folic acids significantly increases. Vitamin C protects low-density lipoprotein cholesterol from oxidation and, accordingly, the walls of blood vessels from the deposition of oxidized forms of cholesterol.

Ability to successfully cope with the emotional and physical burden of stress to a greater extent depends on ascorbic acid more than on any other vitamin. The adrenal glands, which secrete the hormones needed to act stressful situations, contain more ascorbate than any other part of the body. Vitamin C helps produce these stress hormones and protects the body from toxins produced during their metabolism.

Our body cannot store vitamin C, so we need to constantly get it in addition. Because it is water soluble and susceptible to temperature, cooking with heat treatment destroys it.

Lack of ascorbic acid:

Vitamin C deficiency can be of two types:

• Severe – has symptoms such as muscle pain, apathy, lethargy, dry skin, aches and weakness, as well as bleeding gums;
• Acute - the following symptoms are characteristic: tooth loss, heart disease, hypotension, disruption of the functioning of the gastrointestinal tract and hemorrhages in the subcutaneous tissue.

An acute form of ascorbic acid deficiency can lead to serious consequences - a disease called scurvy. This disease characterized by disruption of cartilaginous structures, destruction tubular bones, and decreased brain function.

Scurvy on primary stages It has following symptoms:

• Dizziness, weakness and fatigue;
• Irritation and drowsiness;
• Pain in the calf muscles and joints.

These symptoms appear several months after the onset of vitamin deficiency and do not indicate the presence of the disease, but are only its harbingers. If scurvy moves into a progressive stage, in which changes in gum tissue are observed, then this is an alarming sign, as it threatens not only serious damage to the health of the entire body, but also death.

Scurvy in an advanced state has the following signs of the disease:

• Specific pallor;
• Blueness of the mucous membranes;
• Changes in interdental papillae;
• Bleeding gums;
• Internal hemorrhages in the oral cavity;
• Increased salivation;
• Pain when chewing food.

The first symptoms of vitamin deficiency of this vitamin indicate the need for emergency measures to compensate for the deficiency of this element. At untimely treatment There is a gradual destruction of human systems and organs, which entails disappointing consequences:

• Attachment of secondary infections;
• Complete loss of teeth;
• Acquiring a specific appearance;
• Severe muscle and joint pain that blocks movement;
• Suppression of intestinal and gastric motility;
• Insufficient secretion of digestive enzymes.

Due to the development of the disease resulting from a lack of vitamin C, cardiac system disorders may occur. On this state indicate such signs as increased blood pressure, increased heart rate and weakened heartbeat. A long-term lack of ascorbic acid in a disease such as scurvy can lead to massive hemorrhages, bone fractures, disability and even death.

How is vitamin C beneficial for children?

Ascorbic acid is important for children at any age, but I would like to highlight the special conclusions of some experts. Vitamin C is prophylactic, which allows you to avoid sudden infant death (in infancy). This does not mean that babies need an increased intake of vitamin C. All important vitamins the baby receives it with mother's milk or with artificial nutrition(modern mixtures are enriched with vitamins). It is strictly forbidden to use vitamin complexes independently without a doctor's prescription. If necessary, the doctor prescribes vitamins and also gives recommendations on the organization of the child’s nutrition (timing of introducing complementary foods) or on the organization of nutrition for the nursing mother. Exactly on normal nutrition should be paid attention during this age period.

One of the most famous beneficial effects of “ascorbic acid” can be called positive influence for immunity. Vitamin C is often recommended for children during colds. It helps resist colds and speed up recovery.

This vitamin helps wounds and burns heal faster, recover faster after operations, is considered a natural laxative, and reduces the likelihood of blood clots.

Benefits of ascorbic acid for a child:

• Improves immunity
• Helps fight viruses
• Helps treat colds
• Heals wounds
• Helps with recovery after surgery
• Positive effect on blood

Hair treatment:

Vitamin C is needed for hair no less than other vitamins, especially group B. As you know, the latter are responsible for the constant growth of hair, its silkiness and shine. In addition, their deficiency also affects the state of the body as a whole, provoking depression and stress. As a result, the scalp becomes dry and uneven hair oiliness appears: the roots will be oily, and the ends will be dry and brittle.

To restore in these cases, you will also need ascorbic acid - it regulates the activity of all capillaries that supply each individual hair. The role of this vitamin should not be underestimated, since disturbances in blood microcirculation will cause a terrible problem - hair loss. This is the most danger sign for every woman, rather than loss of hair shine or oiliness. During a prolonged imbalance caused by malfunctions of the capillaries, whole strands of hair may fall out, and complete baldness is possible.

Vitamin C, as already noted, is also beneficial for men. In fact, when a man’s hair began to fall out, what he started timely treatment with vitamin C can restart functions hair follicles and therefore stimulate hair growth.

Dental treatment:

Vitamin C is healthy gums and strong teeth.

This process is especially pronounced in the gums and jaw alveoli, which differ from all other bones of the body in the most high content calcium. Our teeth are attached here, which, when biting food, have to withstand heavy loads. Increased doses of vitamin C can eliminate bleeding gums in no time, as it can literally strengthen countless small vessels in the gum tissue in just half an hour.

Calcium alone travels too slowly to the body's cells, especially when a lot of it is needed. With vitamin C, it forms chemical complexes, so-called chelates, and with their help is delivered to the right place with truly courier speed. This is especially noticeable when supplying calcium to dentin. Without this vitamin, calcium loses half of its beneficial qualities.

Calcium and vitamin C are secret competitors of dentists, or rather, they themselves are natural dentists. Some American biochemists, instead of brushing their teeth, eat lemon twice a day. They have absolutely clean teeth and fresh breath thanks to self-cleaning means of the mouth, which includes saliva. Vitamin C kills bacteria that cause dental caries, strengthens gums, and calcium converts jaw bones and teeth into an impregnable fortress. “It’s healthier than scratching your gums with a toothbrush three times a day,” say modern biochemists. As evidence, they refer to jaws found during archaeological excavations of people who lived 5 or even 10 thousand years ago, whose teeth were all healthy, although there was no toothpaste or dentists then.

Ascorbic acid also carries sulfuric acid salts throughout the body's cells. If these salts are not enough, connective tissues Microscopic tears occur, which most often manifests itself in bleeding gums and poorly healing wounds. What is very important: if the gums begin to bleed, then in most cases hidden internal bleeding appears throughout the body.

Cold treatment:

Although vitamin C cannot protect us from influenza viruses and other colds, its beneficial properties are still used to prevent and treat ARVI.

World famous biochemist and owner of two Nobel Prizes Linus Pauling devoted many years to studying the properties of vitamin C. The scientist became interested in its biological effects in the late sixties of the 20th century.

In 1971, Pauling completed the monograph “Vitamin C and the Cold.” The scientist believed that loading doses of ascorbic acid - the best remedy prevention of colds.

But don't rush to follow his advice! Modern research showed that humans do not need “horse” doses of this vitamin, because its excess is excreted by the kidneys unchanged.

A synthetic analogue of ascorbic acid is often added to drugs designed to alleviate the symptoms of influenza and other acute respiratory viral infections. Of course, powders and tablets are not as pleasant a treat as tangerines or strawberries, but in their properties synthetic vitamin C is not inferior to natural.

Now let's move on to the main thing - why do the mentioned drugs contain ascorbic acid and how can it help a person with a cold? The fact is that vitamin C stimulates the synthesis of interferons - protein compounds that our immune system produces to fight enemies ( pathogenic bacteria and viruses).

That is, vitamin C cannot neutralize, for example, the influenza virus, but it can enhance natural protection our body, thereby alleviating the symptoms of the disease and shortening its duration.

Benefits for weight loss:

By the way, this vitamin stabilizes body weight. It takes part in the synthesis of carnitine from the amino acid lysine. This is of utmost importance for all obese people. Carnitine is a kind of taxi that picks up fat molecules from the blood and delivers them inside cells for oxidation and energy production. Since it is vitamin C that ensures the production of stress hormones that convert fat into a digestible form, it more than anyone cares about the slimness of our figure.

It is curious that animals in nature, with the help of vitamin C, maintain a stable weight until death. This vitamin also has other functions in the body. It releases iron from the intestinal walls and bile and delivers it to the blood to saturate the cells with oxygen.

Since it is vitamin C that ensures the production of stress hormones that convert fat into a digestible form, it more than anyone else cares about the slimness of our figure, and indeed about beauty in general.

Vitamin C with Zinc:

Today you can often see in pharmacies combination drugs containing vitamin C (ascorbic acid) and zinc.

• Zinc. It is an important microelement for the body; it is necessary for the functioning of the immune system and is involved in many metabolic processes, is integral part more than 90 different enzymes. Zinc increases the body's resistance to colds and has antiviral and antitoxic properties.
• Vitamin C. Helps increase the body's nonspecific resistance to infections. It stimulates the body's immune system to fight colds and flu. Vitamin C also plays an important role in metabolic processes and the formation of the body's antioxidant status. Vitamin C increases the concentration of interferon and antibodies in the blood, activates the production of leukocytes and immune proteins, which together quickly increases the body's defenses.

What foods contain ascorbic acid?

Vegetables and fruits, the main suppliers of vitamin C, are preferably eaten raw. The longer they are stored, the lower their concentration of ascorbic acid.

During storage or processing, especially when heated, a significant portion of vitamin C is lost. Ready-to-eat salads in plastic packaging, which are offered in supermarkets, tend to contain more harmful and toxic substances (due to the presence of pest control agents, preservatives and etc.) than vitamin C. The same, although to a lesser extent, applies to frozen fruits and vegetables.

Fruits and vegetables are still the main suppliers of vitamin C. They should be eaten raw whenever possible, since heat destroys most of the vitamin they contain.

The following foods are especially rich in this vitamin: (in milligrams per 100 g.)

• Elderberry - 37.1
• Kiwi - 26.7
• Oranges - 35.4
• Lemons with pulp - 34.0

• Beets, onions - 26.2
• Spinach, broccoli - 26.1
• Green peas - 26.0
• Kohlrabi - 25.8
• Asparagus - 23.7
• Cabbage - 23.6
• Liver - 22.2
• Blackberry - 21.2
• Soybeans - 18.5
• Potatoes - 18.0
• Tomatoes - 16.9
• Artichokes - 10.2
• Apples - 8.8

Contraindications:

An overdose of vitamin C is a rare occurrence; the body does not have a reserve of this substance. Everything that is consumed with food is immediately consumed by the body, and the excess is excreted by the kidneys, through the intestines and sweat glands. But when using synthetic ascorbic acid or injecting the substance, some difficulties may arise.

• Increased blood clotting, thrombophlebitis and thrombosis (blockage of blood vessels with blood clots).
• Poisoning with this vitamin in combination with glucose can lead to disruption of the pancreas. In this case, glucose appears in the urine and glycogen synthesis is disrupted - this is the main form of storage of its excess in the human body.
• Excessive repeated intake of the vitamin with food disrupts the functioning of the stomach glands, which manifests itself in the form of heartburn, nausea and pain.
• Such a symptom of an overdose of ascorbic acid, such as an allergic reaction in the form of urticaria, is rare, but with hypersensitivity to the drug is possible.
• Impaired kidney function: changes in urine, constant overdose of vitamins often lead to the appearance of kidney stones.
• This is another factor in the development of arterial hypertension.

Vitamin C is found in four various forms, so-called stereoisomers (in this case, its atomic composition is always the same, it’s just that the molecule has a different spatial structure). This gives the vitamin the opportunity to perform various functions in the metabolic process, making it extremely versatile.

The most active natural stereoisomer of ascorbic acid is L-ascorbic acid.

After vitamin C enters the intestines with food, it immediately appears almost instantly in the blood, in the intercellular space and cells. According to the latest data, the vitamin C molecule has its own transport protein, thanks to which it penetrates into cells.

Ascorbic acid reaches its highest concentration in the adrenal cortex and central nervous system. The content of vitamin C is also high in leukocytes, white blood cells that play an important role in immune system, it is also involved in the formation of hemoglobin in red blood cells.

By the way, this concentration of the vitamin in the body has its own limit, beyond which the vitamin simply stops being transported into the cells. Therefore, it is much wiser, for example, to eat several oranges throughout the day, instead of eating them all at once. Some of the vitamin is stored in the kidneys, from where it then enters the metabolism.

The activity of vitamin C is manifested throughout the body.

It helps strengthen the smallest blood vessels, cell membranes, and participates in the biosynthesis of collagen and elastin - special connective tissue proteins, supporting components of cartilage, bones, and vessel walls. Thanks to these properties, vitamin C prevents subcutaneous hemorrhages, accelerates the healing process of wounds and other skin damage, and strengthens the gums and ligaments connecting bones.

In addition, ascorbic acid smoothes and strengthens the walls of blood vessels - from microscopic capillaries to thick veins. Thanks to this property, vitamin C helps with varicose veins and hemorrhoids.

If these salts are not enough, micro-tears can occur in the connective tissues, and then the gums begin to bleed... Ascorbic acid also helps supply calcium to the jaw bones and teeth.

In addition, being an antioxidant, ascorbic acid helps the body use other antioxidants, it protects body cells and other vitamins from oxidation, and provides direct protection of proteins, lipids, DNA and RNA from the damaging effects of free radicals and peroxides. That is why vitamin C, along with other “healing” vitamins such as B5, E and PP, are added to various skin creams.
