Vitamins and dietary supplements: what is the difference

Vitamins and dietary supplements: we reveal the essence of differences, advantages and risks

The distinction between vitamins and biologically active additives (dietary supplements) is often blurry, which gives rise to confusion among consumers. Both types of products are positioned as means that contribute to maintaining health and improving well -being, however, their composition, regulatory framework and goals of use are significantly different. In this comprehensive analysis, we will consider key aspects that determine vitamins and dietary supplements, their differences, advantages, risks and rational use.

I. Vitamins: the basis of life and health

Vitamins are organic compounds necessary for the normal functioning of the human body. They are not produced by the body in sufficient quantities (with the exception of vitamin D, which is synthesized under the influence of sunlight) and should come with food or in the form of additives. Vitamins play a key role in metabolic processes, maintaining immunity, growth and development of cells, as well as in protection against free radicals.

A. Classification of vitamins:

Vitamins are divided into two main groups depending on their solubility:

1. Fat -soluble vitamins: This group includes vitamins A, D, E, and K. They dissolve in fats and accumulate in the body, in particular, in the liver and adipose tissue. This means that excessive consumption of fat -soluble vitamins can lead to their accumulation and, as a result, to hypervitaminosis, a state characterized by toxic effects on the body.

   • Vitamin A (Retinol): It is important for vision, bone growth, maintaining the health of the skin and mucous membranes, as well as for immune function. Sources: liver, fish oil, egg yolk, dairy products, carrots, spinach. Vitamin A deficiency can lead to vision of vision (especially in the dark), dry skin, increased susceptibility to infections. Hypervitaminosis A is manifested by headache, nausea, vomiting, hair loss, bone pain.

   • Vitamin D (calciferol): It is necessary for the absorption of calcium and phosphorus, which is important for the health of bones and teeth. It also plays a role in immune regulation and cell growth. It is synthesized in the skin under the influence of sunlight. Sources: fish oil, fatty fish (salmon, sardines), egg yolk, enriched products (milk, cereals). Vitamin D deficiency can lead to rickets in children and osteomination in adults, as well as increased risk of fractures. Hypervitaminosis D is manifested by nausea, vomiting, weakness, constipation, bone pain, and the formation of kidney stones.

   • Vitamin E (tocopherol): It is a powerful antioxidant that protects the cells from damage caused by free radicals. It also plays a role in maintaining the health of the skin and the immune system. Sources: vegetable oils (sunflower, olive, soybean), nuts, seeds, green leafy vegetables. Vitamin E deficiency is rare, but can lead to neurological disorders and muscle weakness. Hypervitaminosis E can affect blood coagulation and increase the risk of bleeding.

   • Vitamin K (Fillokhinon, Menakhinon): It is necessary for blood coagulation and maintaining bone health. It is synthesized by bacteria in the intestines. Sources: green leafy vegetables (spinach, broccoli, cabbage), vegetable oils, liver. Vitamin K deficiency can lead to bleeding. Hypervitaminosis is rare.

2. Water -soluble vitamins: This group includes group B vitamins (B1, B2, B3, B5, B6, B7, B9, B12) and vitamin C. They dissolve in water and do not accumulate in the body in significant quantities. Excess water -soluble vitamins are usually excreted in the urine, which reduces the risk of hypervitaminosis. However, high doses of some water -soluble vitamins can also cause undesirable effects.

   • Vitamin B1 (TIAMIN): It is necessary for the metabolism of carbohydrates, the functioning of the nervous system and the heart. Sources: pork, liver, cereals, legumes, nuts. Vitamin B1 deficiency can lead to Beri-Beri’s disease (neurological and cardiovascular disorders).

   • Vitamin B2 (Riboflavin): It is important for energy metabolism, maintaining the health of the skin and vision. Sources: dairy products, meat, eggs, green vegetables, cereals. Vitamin B2 deficiency can lead to inflammation of the mucous membranes (mouth, tongue), cracks in the corners of the mouth, dermatitis.

   • Vitamin B3 (Niacin): It is necessary for the metabolism of fats, carbohydrates and proteins, as well as for the functioning of the nervous system. Sources: meat, fish, poultry, peanuts, mushrooms, cereals. Vitamin B3 deficiency can lead to Pellagra (dermatitis, diarrhea, dementia). High doses of niacin can cause redness of the skin, itching, nausea.

   • Vitamin B5 (pantotenic acid): Participates in the metabolism of fats, carbohydrates and proteins, as well as in the synthesis of hormones and cholesterol. Widely distributed in food products. Vitamin B5 deficiency is rare.

   • Vitamin B6 (Pyridoxin): E amino acids, the synthesis of neurotransmitters and hemoglobin are necessary for the metabolism. Sources: meat, fish, poultry, legumes, nuts, bananas, potatoes. Vitamin B6 deficiency can lead to anemia, dermatitis, and neurological disorders. High doses of vitamin B6 can cause neurological problems.

   • Vitamin B7 (Biotin): It is necessary for the metabolism of fats, carbohydrates and proteins, as well as to maintain healthy skin, hair and nails. Sources: liver, eggs, nuts, seeds. Vitamin B7 deficiency is rare.

   • Vitamin B9 (folic acid): It is necessary for the synthesis of DNA and RNA, as well as for the formation of red blood cells. It is especially important during pregnancy to prevent defects in the nervous tube in the fetus. Sources: green leafy vegetables, legumes, liver, enriched cereals. Vitamin B9 deficiency can lead to anemia and defects of the nervous tube in the fetus.

   • Vitamin B12 (cobalamin): It is necessary for the formation of red blood cells, the functioning of the nervous system and the synthesis of DNA. Contained only in animal products. Sources: meat, fish, bird, dairy products, eggs. Vitamin B12 deficiency can lead to anemia and neurological disorders. Vegetarians and vegans need to take vitamin B12 additives.

   • Vitamin C (ascorbic acid): It is a powerful antioxidant necessary for the synthesis of collagen, strengthen the immune system and the absorption of iron. Sources: citrus fruits, berries, pepper, broccoli, potatoes. Vitamin C deficiency can lead to scurvy (bleeding gums, tooth loss, weakness). High doses of vitamin C can cause diarrhea.

B. The use of vitamins:

Vitamins are used to prevent and treat vitamins deficiency, as well as to maintain general health and improve well -being. Vitamin preparations are available in various forms: tablets, capsules, chewing tablets, liquids, injections.

• Prevention of vitamin deficiency: Vitamin additives can be recommended to people who do not receive enough vitamins with food, for example, vegetarians, vegans, pregnant women, older people, people with certain diseases.
• Treatment of vitamins deficiency: Vitamin preparations are used to treat diseases caused by deficiency of vitamins, such as scurvy, Beri-Buri, Pellagra, Rachite, Osteomulation.
• Maintenance of general health: Vitamins can be useful for maintaining immunity, improving the condition of the skin, hair and nails, increasing energy and improving cognitive functions.
• Special needs: Some people may need increased consumption of vitamins in connection with certain conditions, such as pregnancy, breastfeeding, intense physical activity, stress.

C. Risks and warnings:

Although vitamins are necessary for health, their excessive consumption can be harmful. It is important to follow the recommended doses and consult a doctor before taking vitamin preparations.

• Hypervitaminosis: As mentioned earlier, excessive consumption of fat -soluble vitamins can lead to their accumulation and hypervitaminosis, which can cause various side effects.
• Interaction with drugs: Some vitamins can interact with drugs by changing their effectiveness or causing undesirable side effects. For example, vitamin K can reduce the effectiveness of anticoagulants.
• Individual intolerance: Some people may have individual intolerance to certain vitamins, manifested by allergic reactions or other side effects.
• Product quality: The quality of vitamin preparations can vary depending on the manufacturer. It is important to choose products from trusted and reliable manufacturers.

II. Biologically active additives (dietary supplements): wide spectrum and uncertainty

Biologically active additives (dietary supplements) are products designed to supplement the diet and contain biologically active substances, such as vitamins, minerals, amino acids, plant extracts, probiotics and other ingredients. Bades are not drugs and are not intended for the treatment of diseases. They are positioned as means of maintaining health, improving well -being and prevention of diseases.

A. Classification of dietary supplements:

Bades are classified according to the composition and purpose:

1. Vitamin-mineral complexes: Contain a combination of vitamins and minerals.
2. Plant extracts: They contain extracts of various plants with alleged useful properties, such as ginseng, echinacea, ginkgo bilobe.
3. Probiotics and prebiotics: They contain living microorganisms that are useful for intestinal microflora, or substances that contribute to their growth.
4. Amino acids: Contain amino acids necessary for protein synthesis.
5. Fatty acids: Contain fatty acids, such as omega-3, necessary for the health of the heart and brain.
6. Enzymes: Contain enzymes that improve digestion.
7. Other dietary supplements: This category includes various products, such as chondroprotectors (for joint health), antioxidants (for protection against free radicals) and others.

B. The application of dietary supplements:

Bades are used for various purposes, including:

• Supplement of the diet: Bades can be useful for people who do not receive enough nutrients with food.
• Health support: Bades can help maintain the health of various organs and systems, such as the immune system, the cardiovascular system, the nervous system, the digestive system.
• Improving well -being: Bades can help improve well -being, increase energy, reduce stress, improve sleep.
• Prevention of diseases: Some dietary supplements can have properties that contribute to the prevention of diseases such as cardiovascular diseases, cancer, osteoporosis.
• Special needs: Some people may need to take dietary supplements in connection with certain conditions, such as pregnancy, breastfeeding, intense physical activity, stress.

C. Regulatory aspects:

Unlike drugs, dietary supplements do not pass strict clinical trials and do not require approval of regulatory authorities before entering sale (in most countries, including Russia). This means that dietary supplement manufacturers are not required to prove the effectiveness and safety of their products. Control of the quality of dietary supplements is carried out, but it is less strict than monitoring the quality of drugs.

D. Risks and warnings:

When using dietary supplements, the following risks and warnings should be taken into account:

• Unproven effectiveness: The effectiveness of many dietary supplements has not been proved by scientific research.
• Low quality: The quality of dietary supplements can vary depending on the manufacturer. Some dietary supplements may contain impurities, pollutants or incorrect dosage of active substances.
• Interaction with drugs: Bades can interact with drugs by changing their effectiveness or causing undesirable side effects.
• Side effects: Some dietary supplements can cause side effects, such as allergic reactions, digestive disorders, headaches.
• Disease disguise: Reception of dietary supplements can mask the symptoms of diseases and complicate their diagnosis.
• Self -medication: Do not use dietary supplements to self -medicate serious diseases. It is important to consult a doctor to make a diagnosis and prescribe treatment.
• Insufficient information: Information about dietary supplements can be incomplete or inaccurate. It is important to critically evaluate information about dietary supplements and consult a doctor or pharmacist.
• Lack of control: Due to less strict control than for drugs, there is a risk of acquiring falsified or low -quality dietary supplements.
