They are absorbed in fatty foods, and they are insoluble in water. After absorption, the substances are stored in adipose tissue and accumulate in the liver tissues. When needed, they enter the tissues, this happens daily.
There are 4 groups in total:

• D – sterols;
• A – has two vitamers, monohydric alcohol;
• E – tocopherols;
• K – quinone.

Let's consider what processes they influence and what their role is for humans.

What vitamins are fat soluble?

The list of fat-soluble vitamins has the following properties:

• Accumulate in the tissues of internal organs;
• Participate in maintaining the integrity of the membranes of nerve and other cells.
• Interacts with steroids.
• They are excreted from the body primarily by the kidneys.
• Some of the substances that dissolve in fats are produced by the body itself. Which vitamins are fat-soluble and do not come only from outside? The body produces vitamin D under the influence of ultraviolet rays, K is produced by intestinal microflora, A is synthesized in the event of the breakdown of provitamins.

Water- and fat-soluble substances participate in metabolic processes. It is important to ensure that the diet is balanced; if it is not possible to eat properly, a person is recommended to take multivitamin complexes, you can buy them at any pharmacy.

Group A

This group is divided into retinol and dehydroretinol.
Plays an important role:

• has an antioxidant effect, prevents the release of free radicals, prevents aging of tissues and organs;
• for children it is especially important - fat-soluble vitamin A - is involved in the construction of the skeleton and the development of bone tissue;
• accelerates the restoration of damaged tissues;
• increases resistance to stress;
• prevents the development of rickets in children;
• prevents loss of vision and eye diseases;
• strengthens the immune system.

If you take group A for a long time, you can harm the body, since in large dosages it becomes harmful and toxic.
The most important reason for maintaining good health is the correctly selected dosage:

• men – up to 1000 mcg;
• women – up to 800 mcg;
• for children – about 500 mcg.

The maximum possible dosage, which is recommended only for acute deficiency, is 3000 mcg. The substance has a beneficial effect on lung tissue, the condition of the skeletal system, hair, teeth, and nails. Foods rich in vitamin A should be present in the diet of a small child.

Group E

Can enter into C, selenium. They enhance the beneficial effects on the activity of internal organs and skin. With a deficiency, dryness of the epidermis appears, inflammatory processes occur, and regeneration processes take longer and are more difficult. Contains alpha, beta, gamma tocopherols. This group has the following effects on the body:

• improves the functioning of nerve fibers and muscle tissue;
• enhances the function of male and female reproductive organs;
• prevents aging of the body;
• strengthens nails, hair, improves the condition of the skin.

Particularly useful for people with a predisposition to cancer. Strengthens the immune system, preventing infectious and viral diseases. Needed by people suffering from problems with blood vessels, as it increases their strength. Reduces fatigue and increases performance. With normal levels of this substance in the body, the patient always has good blood readings.

Group D

Fat-soluble vitamin D is produced independently by the body under the influence of sunlight. The composition contains calciferol, cholecalciferol lamisterol, dihydrotachysterol - therefore the group is divided into categories.

They play the following role:

• mitochondrial activity improves;
• normalize the structure of cells, restoring their membranes;
• accelerate the regeneration of organs and tissues;
• responsible for the health of the skeletal system;
• ensure normal functioning of the thyroid gland and hormones;
• accelerate the synthesis of hormones;
• take part in the metabolism of calcium and phosphorus;
• strengthen bones, teeth, hair;
• prevent the occurrence of cancer.

Scientists have conducted studies that have shown that this vitamin prevents cancer such as cancer of the female and male reproductive organs, brain, leukemia, and breast cancer. It is formed in human skin under the influence of ultraviolet radiation, so sunbathing in moderation can safely be called beneficial.
It has a beneficial effect on the operation of the following systems:

1. Leather. The form of the vitamin is applied externally if there is a need to treat psoriasis. The components contained in this fat-soluble vitamin eliminate scaliness of the skin.
2. Immunity. Increases due to its effect on the bone marrow, which is responsible for the synthesis of monocytes.
3. Hormonal background. The vitamin regulates the production of insulin, which affects blood glucose levels.
4. Nervous system. Maintains normal levels of calcium in the blood, which promotes normal transmission of impulses to muscles and nerves. Restores protective cell membranes.

Vitamin D is a fat-soluble vitamin, and the substance is included in the complex therapy of multiple sclerosis. When the disease occurs, a person’s nerves are gradually destroyed; the vitamin is recommended for people with pathology to maintain them in normal condition.

Group K

This group of fat-soluble vitamins contains elements such as menaquinone, phylloquinone. They have a special synthesis mechanism and participate in the following processes occurring in the body:

• correct blood clotting;
• improve kidney function;
• improve metabolism;
• strengthen the vascular system;
• add energy and increase performance.

If there is a deficiency, a person may be bothered by pathologies of the gallbladder and ducts. Deficiency also causes unpleasant symptoms such as:

• painful menstruation;
• bleeding in the gastrointestinal tract;
• gum diseases, etc.

Additionally, a fat-soluble vitamin is included in a person’s diet if a planned operation is planned in order to normalize blood clotting.

Group F

• improving the functioning of the cardiovascular system;
• regulate metabolism in tissues;
• prevent atherosclerosis;
• promote rapid healing of the skin in case of damage.

Combined with vitamins from group D, which improves the absorption of phosphorus and calcium.

Fat-soluble vitamins and products containing them

Experts have found that vitamins that are insoluble in water are found in food products. You can provide yourself with a normal daily intake of vitamins by properly preparing your diet. It is better to consume foods fresh or steamed - this will help retain more healthy nutrients.

What foods should you include in your diet to ensure a normal daily dose of nutrients? Let's consider this issue in detail.

1. Vitamin A. It is found in carrots, pumpkin and other yellow foods. Tomatoes, plums, and raw potatoes also contain this fat-soluble vitamin. Don't neglect tomatoes. Include milk, zucchini, and spinach in your diet if you are deficient in the substance. Vitamin deficiency can be caused by frequent exhausting diets, bad habits (more specifically, alcoholism), and gastrointestinal diseases.
2. Vitamin D. Beef, beef by-products, egg yolk, vegetable oils. Fish oil and cod liver contain a fat-soluble vitamin. Mushrooms and seafood should be on the table if there is a shortage. An incorrect diet and too little exposure to the sun are the reasons for the deficiency.
3. Vitamin E. Contained in sprouted wheat, milk, and vegetable oils. The lack of this substance is caused by an unbalanced diet, during a diet - when it involves the complete exclusion of fats from the diet. Taking oral contraceptives causes a deficiency.
4. Vitamin K. Contained in fresh onions, spinach, lentils, seaweed. The cause of the shortage is liver and pancreas diseases.
5. Vitamin F. Contained in fish oil, so if there is a deficiency, you need to add fatty fish to your diet: trout, salmon. Also present in olive oil and dried fruits. A lack of nutrients is observed in patients on a diet that excludes fats from their diet.

Let's consider what symptoms may bother people suffering from vitamin deficiency:

1. A. The epidermis becomes dry, while there is always a feeling of tightness in the mouth, and the hair becomes dull. Many people complain of bone pain, vision problems, and hair becoming lifeless.
2. D. With a lack of this vitamin, a person may experience frequent convulsions, increased nervous excitability, and possible manifestation of rickets.
3. E. Poor blood tests, anemia, myopathy, fatigue, and muscle weakness.
4. K. A person is susceptible to cardiovascular diseases - in particular, heart disease, hypocoagulation.
5. F. Problems with the skin, the occurrence of allergic reactions, inflammatory processes.

Taking into account all the factors, it is worth remembering that fat-soluble vitamins must be consumed in sufficient quantities, but you should not be too zealous, since hypervitaminosis may occur - an unpleasant condition that is accompanied by a number of dysfunctions of the body.

Fat-soluble and water-soluble vitamins are divided into 2 large groups, based on their physical properties. The connection with certain foods and protection against disease has been traced back to Ancient Egypt. They learned to overcome scurvy, night blindness, and beriberi long before the discovery of vitamins (and this happened already in 1911, although speculation about their existence arose even earlier).

Now everyone probably knows about these connections, but many of the nuances remain a mystery. To completely dispel doubts, in this article we will analyze in detail the main functions of vitamins, what you need to eat and how to rationally structure your diet. After all, these bioactive substances play a huge role in regulating processes and must be present in our menu.

In fact, what these biologically active substances have in common is only an absolute necessity for the body. The vitamins themselves have a different chemical nature and structure, and act as a “team”.

Their peculiarity is the inability to accumulate in the body; they are excreted in urine per day, except for B12 (for example, nutrient C, which in animals is synthesized and accumulates in the liver independently, and a person must consume it daily). These compounds are extremely unstable and are easily destroyed by heat or metal oxidation.

They are not formed in the body. The functions of water-soluble vitamins are extremely diverse; this group plays a special role in the regulation of metabolic processes. influencing growth, mental and physical activity, increases the body's resistance to diseases, source - plants and animals. If there is a deficiency (vitaminosis) of even one link in the chain of vitamin elements, metabolism is disrupted to a greater or lesser extent and affects a person’s well-being. After all, one necessarily complements the other, and they are interchangeable, which is why they are closely interrelated.

Ascorbic acid (vitamin C)

The most popular and famous power supply. It is an important antioxidant (reduces the aggressive effects of reactive oxygen species and reduces the aging process). The compound is quite “capricious” and can be destroyed not only when processing vegetables and fruits, but also under the influence of metals.

Main properties:

• Participates in the synthesis of hormones of the adrenal glands (which are extremely important for the regulation of blood pressure and performance) and the thyroid gland.
• Helps improve immunity.
• Neutralizes harmful nitrite salts (contained in sausages).
• Reduces the risk of developing atherosclerosis.
• Provides acceleration of collagen synthesis (important for maintaining skin tone and connective tissues).
• Increases iron absorption.
• Will speed up healing.

The need for the element is not always the same; it should be supplied in much larger quantities for colds, malignant neoplasms and infections. Symptoms of vitamin C deficiency are increased fragility of blood vessels, which leads to multiple bleeding - pulmonary, uterine, gastric. Poor circulation also affects the condition of teeth, leading to their loss. This type of vitamin deficiency is also called scurvy.

Fact: Smoking just 1 cigarette destroys 25 mg of the vitamin in our body.

Insufficient consumption of a nutrient (a biologically significant, non-replaceable element that enters the body from outside) leads to decreased performance, increased fatigue, and an increase in the number of colds. Iron deficiency anemia may develop.

Foods rich in ascorbic acid

Thiamine (vitamin B1)

Water-soluble vitamins include the entire group B. The most important action (or B1) is participation in carbohydrate metabolism, although it plays an important role in almost all types of metabolism. The production of coenzyme carboxylase and the enzyme acetylcholine depends on the vitamin. They ensure adequate conduction of nerve fibers.

Vitamin B1 deficiency leads to disruption of the functioning of the peripheral and central nervous systems and a decrease in normal carbohydrate processing.

Nutrient deficiency causes.

• Memory impairment
• Paresis of the limbs,
• Migraines,
• Increased irritability.
• Cardiac dysfunction - pain, shortness of breath, rapid heartbeat, “cardiac” swelling (lower legs).
• Symptoms of dyspepsia are nausea, diarrhea or constipation, loss of appetite.

The longer the body does not receive thiamine, the more pronounced the signs of deficiency. In extreme cases (also called beriberi), an unsteady gait appears and paralysis of the legs occurs.

Important: In developed countries, vitamin deficiencies of this vitamin occur quite rarely. The reason for the decrease in its intake into the body may be: a monotonous diet of products made from premium flour, alcohol abuse, and diseases of the small intestine.

Riboflavin (B2)

An important function of the vitamin is to participate in the renewal of body tissues. It helps protect the skin from ultraviolet radiation and increases barrier properties. There is also evidence that sufficient consumption of foods rich in this element increases life expectancy.

Hypovitaminosis leads to quite obvious manifestations in the body:

1. Cracks and peeling of the lips, the appearance of “jams” in the corners of the mouth.
2. Dryness of thin skin - wings of the nose, behind the ears, neck.
3. Visual impairment – ​​decreased color and twilight perception.

B2 deficiency is quite common, especially with a dairy-free diet. The trace element is susceptible to sunlight, so the products that contain it. It is not recommended to expose to direct rays.

Pyridoxine (B6)

Participates in almost all types of metabolism and regulates the synthesis of hormones. Often, symptoms of vitamin deficiency are expressed in disorders of the central nervous system - drowsiness, depression, irritability. Skin manifestations are also possible, usually in the form of redness of the borders of the lips, tongue, inflammatory processes of the oral mucosa and skin.

A sharp decrease in vitamin intake is often provoked by chemotherapy for tuberculosis. The drugs react with the element, making it inactive.

Important: vitamin B6 deficiency in children can lead to the development of anemia.

Cobalamin (B12)

This vitamin, unlike others, can be deposited in the liver depot, from where it is used for several years (if there is no supply). It plays an important role in hematopoiesis, metabolic processes and acetylcholine synthesis.

The element is necessary to maintain a healthy nervous system. A decrease in its consumption can lead to increased irritability, deterioration in the functioning of the pelvic organs, leg paresis, etc. Often there is a deficiency of hemoglobin, anemia, and possible exacerbation of erosive processes in the stomach and intestines.

Usually, strict vegetarians who adhere to a protein-free diet for a long time suffer from severe vitamin deficiencies. B12 deficiency can occur during pregnancy, addiction to alcoholic beverages and microflora imbalance.

Nicotinic acid (PP or B3)

This is the only element of group B that is a medicine. It also has several names: niacin B3; nicotinamide (PP); nicotinic acid. Acid is involved in the regulation of energy metabolism. With prolonged poor nutrition, the development of pellagra is possible - a disease of the nervous system with severe damage to the gastrointestinal tract, skin and central nervous system.

The disease is accompanied by dermatitis, inflammation of the tongue, and diarrhea. A decrease in physical activity, depressive disorders, aggression and psychosis are often observed; it is not without reason that it is called the “vitamin of calm.” Long-term vitamin deficiency can lead to persistent disorders of the brain - dementia.

Pellagra was widespread among the poor, where corn was the staple food. Also, vitamin deficiency PP can cause chronic alcoholism and anti-tuberculosis drugs.

Products contain niacin

Pantothenic acid (B5)

The element takes an active part in the synthesis of enzymes, and is also part of some biologically active substances - coenzyme A (synthesizes fatty acids).

Normally, your own microflora can independently produce this vitamin, but in much smaller quantities - about 3.5 mg per day. Nutrient deficiency results in damage to the small arteries and capillaries of the legs and feet, causing a burning sensation in them. Cramps and joint pain may occur.

Important: B5 is very sensitive to heat treatment.

Folic acid (B9)

The vitamin can be synthesized by our intestinal microflora, but only in the presence of vitamin B10. The properties of the acid are similar to B12, but its deficiency leads to a decrease in all the formed elements of the blood - leukocytes, erythrocytes, platelets. Vitamin deficiency leads to persistent diarrhea, can cause multiple deformities in the fetus, and decreased immunity.

Biotin (N)

Actively participates in the main types of metabolism - fat, protein and carbohydrates. A decrease in its consumption leads to disorders of the nervous, visual, and hematopoietic systems. The main signs of vitamin deficiency are:

• Peeling of the skin on the wings of the nose, behind the ears, on the head.
• Increased hair loss.
• Increased fatigue and decreased mood,
• Severe anemia
• Characteristic smooth tongue.

Fat-soluble vitamins

This group of nutrients includes those vitamins that do not dissolve in water (how they differ from their hydrophilic counterparts). The division into this group is quite arbitrary, because science has made great strides forward. Scientists have learned to develop new forms by turning them into water-soluble analogues.

Elements of this group tend to cause not only vitamin deficiencies if insufficiently administered, but also provoke hypervitaminosis - poisoning from excess incoming substances. For most vitamins, excess amounts are excreted from the body in the urine. For A and D this rule does not work. They tend to accumulate, which, if taken in excessively high doses, leads to poisoning of the entire body.

Retinol (A)

An extremely versatile nutrient. It is involved in almost all areas of the body. Vitamin A has the greatest effect on vision, skin and the reproductive system. Retinol is involved in growth, accelerates tissue renewal, and supports immunity. This is a kind of “first line” that provides our protection from inflammatory processes and diseases.

The vitamin has antioxidant properties, reducing the aging of the body.

Lack of income actively affects many functions:

• Deterioration of night vision (night blindness).
• Eye damage - dry cornea, keratitis (inflammation) and ulcerative formations.
• Skin damage - inflammatory diseases, acne, dry skin.
• Decreased immune function with increased susceptibility to pneumonia, bronchitis and infectious diseases of the genitourinary system.
• Slow growth in children.

However, this useful element not only causes disruption in the functioning of our body if there is a deficiency, but can also provoke intoxication. With hypervitaminosis A, the skin color changes (yellowness, it becomes almost orange), dryness, itching and flaking appear, and hair loss increases. Asthenovegetative syndrome is characteristic - lethargy, drowsiness, migraine, vomiting is possible.

Calciferol (D)

The most important participant in phosphorus and calcium metabolism. Ensuring normal growth and formation of bone tissue. A sufficient supply of it is especially important in early childhood; deficiency leads to serious consequences and multiple skeletal deformities, causing diseases such as rickets.

In the initial stages of vitamin deficiency, the nervous system is affected - tearfulness, increased sweating (sticky sweat), insomnia. Then, as hypovitaminosis progresses, growth retardation, muscle weakness, and softening of bone and cartilage tissue occur.

In adults, reduced nutrient intake causes osteoporotic changes or osteomalacia (softening). Such changes occur extremely rarely - with an unbalanced diet and a long absence of sunlight in pregnant women, as well as residents of the far north.

An interesting fact is that calciferol is independently produced in our body under the influence of sunlight. Moreover, people with fair skin produce this solar vitamin better than their dark-skinned relatives. Tanning creates a natural barrier against hyperinflux of the element.

Tocopherol (E)

This vitamin is an essential element for the reproductive system, both for women and men. It is involved in the synthesis of gonadotropic hormones (those that contribute to the formation of the follicle, ovulation and normal conception and pregnancy) and many proteins - smooth muscles, collagen, genital mucosa, placenta, etc.

The nutrient has the strongest antioxidant qualities, which are significantly enhanced in the presence of vitamin C. The trace element can not only protect our cells from negative oxidative effects, but also reduce hypoxia (oxygen starvation) of tissues.

Vitamins are usually sold in a complex preparation of A and E. This is necessary to protect vitamin A, which is susceptible to oxidation.

The nutrient can also reduce the amount of cholesterol in the blood and strengthen the immune system.

Hypovitaminosis occurs quite often. Especially in areas with radioactive contamination. Severe forms of deficiency may develop in premature infants.

The main signs of vitamin deficiency are:

• Damage to brain tissue (softening).
• Speech and gait disturbances.
• Muscle weakness.
• Disorder of the functions of the reproductive system - decreased erection, frequent miscarriages.
• Damage to the kidneys and liver.
• Visual impairment (due to connection with vitamin A).

Hypervitaminosis occurs extremely rarely - excess substance is excreted from the body along with bile. The disease may be accompanied by sepsis, necrotic damage to the liver, kidneys and intestines.

Phylloquinone (vitamin K)

Is a blood clotting factor. In addition, it takes part in the synthesis of bone tissue and proteins. Our body (or rather, beneficial intestinal microorganisms) fully provides the necessary supply of nutrients.

Its deficiency is usually associated with liver problems, dysbiosis, and also with the use of certain anticoagulants (for example, dicoumarin, warfarin).

With hypovitaminosis, extensive hemorrhages, ossification of cartilage tissue and the formation of salt plaques on the walls of blood vessels may occur.

Fat-soluble and water-soluble vitamins: table

Fat soluble

Water soluble

Print out the table and check it often when creating your home menu.

All fat-soluble and water-soluble vitamins should be present in our diet, in the form of foods and supplements. Unfortunately, in order to get the required dose of some elements, you need to consume a huge amount of food, and hardly anyone will like this.

Until new publications.

Take care of yourself and your loved ones!

Optimal metabolism in the human body is the first indicator of the fact that it is healthy. Do you want to always be healthy? Then you cannot do without consuming elements such as fat-soluble vitamins. Some are capable of being accumulated by the human body on its own, while others can be obtained by people only by consuming them from the outside (from foods or medications purchased at a pharmacy). The only condition is complete interaction of beneficial substances with the organic solvent.

Substances necessary for the body that participate in metabolic processes with the help of fat are given the “name” fat-soluble vitamins. Their active components begin to decompose, saturating cells with useful substances only when combined with fats, both plant and animal origin. If there is no fat, then the substances needed by the body are practically not absorbed - vitamin deficiency occurs. There is a decrease in immunity, brittle nails, hair, apathy, and a general deterioration in the person’s condition. Excess components of beneficial substances accumulate in the liver and are then removed in the urine.

The role of fat-soluble vitamins in the human body

The main function of vitamins is to saturate every cell of the human body with useful micro- and macroelements. The biological composition of cells is designed in such a way that if there is a lack of one component, they disintegrate and are destroyed. A complex of useful substances taken in a timely manner preserves a person’s youth, beauty, health, and longevity. Some of their components help fight cells against free radicals (group A, D).

Which vitamins are fat soluble - list

Fat-soluble vitamins include groups of substances beneficial to the body such as A, E, D, K, F. If there is a deficiency of at least one component, the functions of organs may be impaired, which affects not only a person’s appearance, but also their well-being. To avoid these consequences, you need to carefully structure your diet. By saturating your nutrition system with all the necessary substances, you can achieve excellent health and gain a beautiful appearance.

Vitamin A

If your visual acuity has decreased, your body’s protective reaction to viruses, or other health problems have appeared, this is the body’s first impulse to a lack of vitamin A. This group of elements is responsible for:

• skin condition;
• normal metabolism in the body;
• formation of teeth and skeletal system;
• the functioning of the immune system, the elasticity of human mucous membranes;
• retinal health (retinol), low light vision.

This substance, ready for consumption, is contained inside the yolk of eggs, liver, and fish fat. The body can produce vitamin A on its own by transformation from beta-carotene, which is found inside legumes, spinach, carrots, pumpkin, apricot, and melon. This substance is found in sweet peppers, milk, cheese products, vegetables and fruits of bright red or orange color.

An excess of a group A substance can lead to the opposite effect. A person will become sick with viral diseases more often, peeling of the skin may appear, vision and the condition of the skeletal system may deteriorate. The main rule is to maintain a sense of proportion so that the daily requirement of this substance inside the body does not exceed the norm necessary for health.

Vitamin E

An important component for prolonging youth, beauty, and reproductive health for all genders is vitamin E, which is based on the substance tocopherol (a powerful antioxidant). Combining it with retinol helps slow down the oxidation process of the latter. Group E substances improve muscle tone and blood circulation within the body. It is better to take them from oils of animal and plant origin, sprouted grains. Meat, milk, liver, eggs help compensate for its deficiency. Otherwise, the functioning of the heart, vascular, and nervous systems is disrupted, which leads to infertility and anemia.

Vitamin D

A substance of group D has a number of advantages:

• normalizes the process of absorption of calcium and phosphorus inside the human intestine;
• participates in the formation of teeth and bones;
• improves the functioning of the immune system;
• has anti-carcinogenic properties (blocks the formation of tumor compounds and cells);
• It can be produced on its own under the influence of ultraviolet radiation and accumulate in adipose tissue and the liver.

This component, beneficial for the body, is found in butter, milk, eggs, cheese, fish fat and liver, and cereal products. It helps prevent breast cancer and osteoporosis in adults. It must be treated with caution. Excess vitamin D causes headaches, muscle weakness, and damage to the blood vessels of the heart and kidneys. Children less than one year of age should take a drug containing a group D substance to avoid the development of rickets.

Vitamin K

The K group component is known for its excellent process control:

• metabolism in bones and connective tissue;
• calcium absorption;
• blood clotting;
• proper functioning of the kidneys.

During the functioning of the digestive system of a healthy person, vitamin K (phylloquinone) is produced and accumulated in the intestines. If there is not enough of it, people experience bleeding from the gums and prolonged healing of cuts and wounds. It is easy to replenish the deficiency of this component in the body from dairy products, cereals, liver, lettuce, cabbage.

Vitamin F

If you have problems with skin, hair, nails, or the cardiovascular system, then it makes sense to compensate for the lack of vitamin F in the body. This complex of polyunsaturated fatty acids (arachidonic, linolenic and linoleic) is responsible for normal blood circulation and improves skin regeneration. Substance F strengthens the immune system and prevents the development of atherosclerosis. They are rich in oil from flax, nuts, olives, corn, and sunflower.

The properties and functions of vitamins A, E, D, K, F are clearly shown in the table below. The classification of these elements allows in some cases to use them as a cure for diseases. These vitamins help to quickly influence metabolic processes in the body, improve not only a person’s appearance, but also his internal functionality. The table shows the benefits of each specific vitamin, what it contains, and the possible harm to the body in case of deficiency.
