Vitamin D for children: why is it needed and how to give it

Vitamin D for children: why is it needed and how to give it

I. Fundamentals of vitamin D and its role in the children’s body

Vitamin D, often called “solar vitamin”, is a fat -soluble vitamin that plays a critical role in maintaining the health of bones, the immune system and the general well -being of the child. Unlike many other vitamins, vitamin D can be synthesized in the skin under the influence of sunlight. However, in modern conditions, when children spend less time in the open air and more often use sunscreen creams, as well as taking into account geographical factors and season, the natural production of vitamin D may be insufficient.

A. Various forms of vitamin D: d2 and d3

There are two main forms of vitamin D: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D2 is mainly obtained from plant springs, such as mushrooms irradiated with ultraviolet light. Vitamin D3, on the other hand, is synthesized in human skin under the influence of sunlight and is also contained in some products of animal origin, such as oily fish, egg yolks and liver.

In general, vitamin D3 is considered more effective in increasing the level of vitamin D in the blood and maintaining it at a stable level compared to vitamin D2. Therefore, when choosing additives with vitamin D for children, preference is usually given to vitamin D3.

B. Vitamin D action mechanism in the body

Vitamin D, obtained from food or synthesized in the skin, passes through two stages of transformation before becoming an active form capable of having its biological effect.

1. The first stage: In the liver, vitamin D turns into 25-hydroxyvitamin D [25(OH)D]also known as calciol. This form of vitamin D is used to assess the level of vitamin D in the blood.

2. The second stage: In the kidneys 25 (OH) D turns into 1.25-dihydroxyvitamin D [1,25(OH)2D]also known as calcitriol. Calcitriol is an active form of vitamin D, which binds to vitamin D (VDR) receptors in various body tissues.

VDR are present in most body cells, including bones, intestines, kidneys, immune cells and brain. Claiming with VDR, calcitriol regulates the expression of genes involved in various physiological processes, such as:

• Regulation of calcium and phosphorus: Vitamin D promotes the absorption of calcium and phosphorus in the intestines, which is necessary to form and maintain the health of bones and teeth. It also regulates the reabsorption of calcium in the kidneys and mobilization of calcium from bones to maintain the normal level of calcium in the blood.

• Support for the immune system: Vitamin D plays an important role in the regulation of the immune system, helping it to fight infections and prevent autoimmune diseases. It promotes differentiation and activation of immune cells, such as T cells and B cells, and regulates the production of cytokines.

• Cell growth and development regulation: Vitamin D is involved in the regulation of cell growth and differentiation, which is important for the normal development of the body. He can also play a role in preventing cancer.

• Maintenance of muscle health: Vitamin D is necessary for the normal function of muscles. Vitamin D deficiency can lead to muscle weakness and pain.

C. The main functions of vitamin D in the children’s body

Vitamin D plays a vital role in maintaining the health and development of children, participating in the following key processes:

1. Formation and strengthening of bones and teeth: Vitamin D promotes the absorption of calcium and phosphorus necessary for the formation and maintenance of strong bones and teeth. Vitamin D deficiency can lead to rickets in children, a disease characterized by softening of bones and skeleton deformations.

2. Support for the immune system: Vitamin D plays an important role in the regulation of the immune system, helping to protect children from infections. It contributes to the activation of immune cells and regulates the production of cytokines, substances involved in the immune response.

3. Improving muscle function: Vitamin D is necessary for the normal function of muscles. Vitamin D deficiency can lead to muscle weakness and pain, which can complicate the motor activity of children.

4. Regulation of mood and cognitive functions: Some studies show that vitamin D can play a role in the regulation of mood and cognitive functions. Vitamin D deficiency can be associated with an increased risk of depression and other mental disorders.

5. Prevention of chronic diseases: Studies show that sufficient consumption of vitamin D can help reduce the risk of developing chronic diseases such as type 1 diabetes, asthma and some types of cancer.

II. Causes of vitamin D deficiency in children

Vitamin D deficiency is a common problem among children around the world. There are several factors that can contribute to the development of vitamin D deficiency in children, including:

A. insufficient stay in the sun

Sunlight is the main source of vitamin D for most people. However, in modern conditions, when children spend less time in the open air and more often use sunscreen creams, the natural production of vitamin D may be insufficient.

• Geographical position: Children living in the northern latitudes, where the sun’s rays are less intense are at greater risk of vitamin D.

• Top of year: In the winter months, when sunny days are shorter and people wear more clothes, the production of vitamin D in the skin decreases.

• Using sunscreen creams: Sunscreen creams, although necessary to protect against the harmful effects of ultraviolet radiation, also block the synthesis of vitamin D in the skin.

• Skin color: People with dark skin have more melanin, pigment, which absorbs ultraviolet radiation. This means that they need more time in the sun to develop a sufficient amount of vitamin D.

B. insufficient consumption of vitamin D with food

Vitamin D is contained in a small amount of food, such as oily fish, egg yolks and liver. Children who do not use these products in sufficient quantities may experience a deficiency of vitamin D.

• Limited diet: Children with allergies to certain products, vegetarians or vegans may have difficulty obtaining a sufficient amount of vitamin D with food.

• Preferences in food: Many children refuse to use useful products containing vitamin D, such as fish and egg yolks.

• Insufficient enrichment of products: In some countries, food products, such as milk and grain products, are enriched with vitamin D. However, in other countries, the enrichment of products with vitamin D is not mandatory, which can lead to a deficiency of vitamin D in children.

C. Diseases affecting the absorption of vitamin D

Some diseases can affect the body’s ability to absorb vitamin D from food.

• Intestinal diseases: Diseases, such as Crohn’s disease, celiac disease and cystic fibrosis, can disrupt the absorption of vitamin D in the intestines.

• Liver and kidney diseases: Diseases of the liver and kidneys can disrupt the transformation of vitamin D into an active form, which leads to deficiency of vitamin D.

D. Other risk factors

• Breastfeeding without taking vitamin D additives: Breast milk does not contain vitamin D enough to meet the needs of the baby, especially if the mother herself experiences a deficiency of vitamin D. Babs who are on breast feeding, it is recommended to give additives with vitamin D from the first days of life.

• Obesity: Vitamin D is a fat -soluble vitamin, and in people with obesity it can accumulate in adipose tissue, which leads to a decrease in its concentration in the blood.

• Premature birth: Premature children are at a higher risk of vitamin D deficiency, since they have fewer vitamin D reserves in the body.

• Reception of some drugs: Some drugs, such as anticonvulsants and glucocorticoids, can affect vitamin D metabolism and increase the risk of deficiency.

III. Symptoms of vitamin D deficiency in children

Symptoms of vitamin D deficiency in children can be diverse and not always obvious, especially in the early stages. It is important to pay attention to the following signs and symptoms:

A. Rahit

Rachite is the most serious manifestation of vitamin D deficiency in children. It is characterized by softening of bones and skeleton deformations.

• Bone deformations: Racititis can lead to deformation of the bones of the legs (O-shaped or X-shaped legs), thickening of the wrists and ankles, chest deformation (rickets) and soft skull (cranitabes).

• Teething delay: In children with rickets, a delay in teething and an increased risk of caries can be observed.

• Muscle weakness: Racititis can lead to muscle weakness, which can complicate the motor activity of the child.

• Growth delay: Rickets can slow down the growth of the child.

B. Other symptoms

In addition to rickets, the deficiency of vitamin D can manifest by other symptoms, such as:

• Fatigue and weakness: Vitamin D deficiency can lead to fatigue and weakness, which can affect the activity and mood of the child.

• Bone pain and muscles: Vitamin D deficiency can cause pain in bones and muscles, especially in the legs and back.

• Increased susceptibility to infections: Vitamin D plays an important role in maintaining the immune system, and its deficit can increase the child’s susceptibility of infections such as a cold and influenza.

• Irritability and mood swings: Vitamin D deficiency can affect mood and lead to irritability and mood swings.

• Motor development delay: In infants, with a deficiency of vitamin D, a delay in motor development can be observed, such as the later beginning of sitting, crawling and walking.

• Bad dream: Some studies show that vitamin D deficiency may be associated with poor sleep.

C. Diagnosis of vitamin D deficiency

If the child has signs and symptoms indicating vitamin D deficiency, you must consult a doctor for diagnosis. Diagnosis of vitamin D deficiency usually includes:

• Medical examination: The doctor will conduct a medical examination of the child to evaluate his general health and identify signs of rickets or other diseases.

• Blood test: A blood test is the most accurate way to determine the level of vitamin D in the body. The doctor may prescribe a blood test for measuring the level of 25-hydroxyvitamin D [25(OH)D]which is an indicator of vitamin D reserves in the body.

• Radiography: In some cases, the doctor may prescribe bone radiography to assess the degree of deformation of bones caused by rickets.

IV. Recommended doses of vitamin D for children

The recommended doses of vitamin D for children depend on the age and the availability of risk factors for vitamin D deficiency. The following recommendations are based on data from the American Academy of Pediatrics (AAP) and other authoritative organizations:

A. Infants (0-12 months)

• All babies on breastfeeding or using less than 1 liter of enriched milk mixture per day should receive 400 IU (international units) vitamin D per day from the first days of life.

• Non -premature babies may require a higher dose of vitamin D, which the doctor must determine.

B. Children (1-18 years old)

• All children and adolescents are recommended to receive 600 IU vitamin D per day.

• Children with risk factors of vitamin D, such as dark skin, obesity, disease affecting the absorption of vitamins, or taking certain drugs, may require a higher dose of vitamin D, which the doctor should determine.

C. The upper permissible levels of vitamin D consumption

It is important not to exceed the upper permissible levels of vitamin D consumption to avoid toxicity. The upper permissible levels of vitamin D consumption for children:

• Infants (0-6 months): 1000 IU per day
• Infants (7-12 months): 1500 me per day
• Children (1-3 years old): 2500 me per day
• Children (4-8 years old): 3000 me per day
• Children (9-18 years old): 4000 me per day

D. Sources of vitamin D

Vitamin D can be obtained from several sources, including:

• Sunlight: Staying in the sun is the main source of vitamin D. However, it is necessary to remember the precautions in order to avoid sunburn. It is recommended to spend 10-15 minutes a day in the sun, without using sunscreen, during periods when the sun is most intensively (from 10:00 to 16:00).

• Food: Vitamin D is contained in a small amount of food, such as fatty fish (salmon, tuna, mackerel), egg yolks, liver and enriched products (milk, grain products, orange juice).

• Vitamin D supplements: Vitamin D additives are a reliable way to ensure sufficient vitamin D consumption, especially for children who do not get enough vitamin D from sunlight and food.

V. How to give vitamin D to children

The correct use of vitamin D additives is crucial for ensuring safety and efficiency.

A. The choice of vitamin D additives

• Vitamin D: Choose additives containing vitamin D3 (cholecalciferol), which is a more effective form of vitamin D than vitamin D2 (ergocalciferol).

• Dosage: Choose additives with a dosage corresponding to the recommended dose for the age of the child.

• Output form: Vitamin D additives are available in various forms, such as drops, tablets, chewing tablets and capsules. Choose a form that is most convenient for your child.

• Composition: Check the composition of the additives for artificial dyes, flavors, sweeteners and other additives that you would like to avoid.

B. Dosage and method of application

• Infants: Infants are usually given vitamin D in the form of drops. Drops can be added to milk, juice or other liquid, or give directly into the mouth.

• Children: Children can be given vitamin D in the form of drops, tablets, chewing tablets or capsules. Tablets and capsules can be swallowed entirely or crushed and mixed with food. Chewing tablets must be carefully chewed.

• Follow the instructions: Always follow the instructions on the label of additives or the doctor’s recommendations regarding the dosage and the method of use.

• Do not exceed the dose: Do not exceed the recommended dose of vitamin D to avoid toxicity.

• Regularity: Give vitamin D regularly to maintain a stable level of vitamin D in the blood.

C. Tips for the use of vitamin D

• Let’s vitamin D during eating: Vitamin D is a fat -soluble vitamin, so it is best to absorb it during food containing fats.

• Keep vitamin D additives in an inaccessible place for children: An overdose of vitamin D can be dangerous for children.

• Consult a doctor: Before taking vitamin D additives, consult a doctor to determine the required dose and make sure that it is safe for your child.

VI. Prevention of vitamin D deficiency in children

Prevention of vitamin D deficiency is an important part of maintaining children’s health.

A. Prenatal care

• Vitamin D intake during pregnancy: Pregnant women should receive a sufficient amount of vitamin D to provide adequate vitamin D reserves in a newborn. The recommended dose of vitamin D for pregnant women is 600 IU per day. In some cases, the doctor may recommend a higher dose.

B. breastfeeding

• Vitamin D additives for babies on breastfeeding: Breast milk does not contain vitamin D enough to meet the needs of the baby, so it is recommended to give supplements with vitamin D from the first days of life for babies on breastfeeding.

C. Proper nutrition

• Inclusion in the diet of products rich in vitamin D: Try to include in the child’s diet products rich in vitamin D, such as oily fish, egg yolks and enriched products.

D. sufficient stay in the sun

• Regular stay in the sun: Regular stay in the sun (10-15 minutes a day without sunscreen in periods when the sun is most intensively) can help increase the production of vitamin D in the skin. However, it is necessary to remember the precautions in order to avoid sunburn.

E. Vitamin D additives

• Reception of vitamin D additives: Vitamin D additives can be necessary for children who do not get enough vitamin D from sunlight and food. Particularly important additives in the winter months and for children with risk factors of vitamin D.

F. Regular medical examinations

• Vitamin D level control: Regular medical examinations allow the doctor to control the level of vitamin D in the blood of the child and detect vitamin D deficiency in the early stages.

VII. Toxicity of vitamin D (hypervitaminosis D)

Although vitamin D deficiency is a more common problem than the toxicity of vitamin D, it is important to know about the risks of an overdose of vitamin D.

A. The causes of hypervitaminosis D

Hypervitaminosis D usually occurs as a result of taking excessively high doses of vitamin D for a long period of time. This is rarely due to an excessive stay in the sun or the use of products rich in vitamin D.

B. Symptoms of hypervitaminosis D

Symptoms of hypervitaminosis D may include:

• Nausea and vomiting
• Loss of appetite
• Frequent urination
• Excessive thirst
• Muscle weakness
• Bone pain
• Constipation
• Irritability
• High blood calcium levels (hypercalcemia)
• Kidney damage

C. Treatment of hypervitaminosis D

Treatment of hypervitaminosis D usually includes the cessation of vitamin D additives and limiting calcium consumption. The doctor may also prescribe medications to reduce blood calcium.

D. Prevention of hypervitaminosis D

It is possible to prevent hypervitaminosis D by observing the following precautions:

• Do not exceed the recommended dose of vitamin D.
• Consult a doctor before taking the additives of vitamin D.
• Regularly control the level of vitamin D in the blood, especially if you take high doses of vitamin D.

VIII. Conclusion

Vitamin D is an important nutrient necessary for the health and development of children. Enough consumption of vitamin D helps maintain bone health, immune system and general well -being. Vitamin D deficiency is a common problem among children, but it can be prevented by sufficient stay in the sun, proper nutrition and taking vitamin D additives. It is important to consult a doctor to determine the necessary dose of vitamin D for your child and make sure that this is safe.
