Section 1: Definition and classification of dietary supplements

Dietary supplements, or biologically active food additives (Dietary Supplements) are concentrates of natural or identical to natural biologically active substances intended for direct intake with food or introduction to food products. They are not drugs and are not intended for the treatment, diagnosis or prevention of diseases. Their main goal is to enrich the diet with individual food substances or their complexes, as well as maintaining the functions of the body within the physiological norm.

The classification of dietary supplements can be carried out according to various criteria, including the composition, form of release, purpose and source of the origin of the components.

• By composition:

  • Vitamins: Contain one or more vitamins (for example, vitamin C, vitamin D, B vitamins). Designed to replenish the deficiency of vitamins in the body. Examples: multivitamin complexes, vitamin D3 in drops, ascorbic acid in tablets.
  • Minerals: They contain one or more minerals (for example, calcium, magnesium, iron, zinc). It is necessary for the normal functioning of the body and maintaining the mineral balance. Examples: calcium with vitamin D, magnesium B6, zinc Picoline.
  • Vitamin-mineral complexes: Combine vitamins and minerals for complex support of the body. Examples: alphabet, complivitis, suprain.
  • Amino acids: Contain amino acids, construction blocks of proteins. They are used to maintain muscle mass, improve sports results and restore after physical exertion. Examples: BCAA (leucine, isolacin, valin), L-carnitine, creatine.
  • Plant extracts: Contain extracts of various plants that have certain biological properties. Examples: Echinacea extract (for immunity), ginkgo biloba extract (to improve memory), milk thistle extract (to maintain liver function).
  • Fatty acids: Contain polyunsaturated fatty acids (PNS), such as omega-3 and omega-6. Important to the health of the cardiovascular system, brain and vision. Examples: fish oil, linseed oil, crill oil.
  • Probiotics and prebiotics: Probiotics are living microorganisms, which, when used in sufficient quantities, have a beneficial effect on the body. Prebiotics are substances that serve as food for probiotics and contribute to their growth and reproduction in the intestines. Used to maintain healthy intestinal microflora. Examples: lactobacilli, bifidobacteria, inulin, fruitoligosaccharides (phos).
  • Food fibers: Unbertable carbohydrates that contribute to the normalization of digestion and maintaining the intestinal health. Examples: fiber, pectin, guar gum.
  • Other biologically active substances: Include various substances with biological activity, such as coenzyme Q10, glucosamine, chondroitin.

• By the form of release:

  • Tablets: A solid form of release containing compressed powder or granules.
  • Capsules: A hard or soft gelatin membrane containing powder, granules or liquid.
  • Powders: Dry substances intended for dissolution in water or other liquid before use.
  • Liquids: Solutions, suspension or emulsion.
  • Chewing tablets and loafers: Designed for resorption in the mouth.
  • Bars: A solid form, often containing a mixture of various ingredients, such as cereals, nuts, fruits and additives.

• For the purpose:

  • To maintain immunity: They contain vitamins, minerals and plant extracts that contribute to the strengthening of the immune system.
  • To improve digestion: Contain probiotics, prebiotics and dietary fibers that normalize the intestines.
  • To maintain the health of the cardiovascular system: Contain omega-3 fatty acids, Q10 coenzyme and other substances that are useful for the heart and blood vessels.
  • To improve cognitive functions: Contain ginkgo biloba extract, group B vitamins and other substances that improve memory and concentration.
  • To maintain joint health: Contain glucosamine and chondroitin, necessary for the restoration and maintenance of cartilage.
  • For sports nutrition: Contain amino acids, creatine and other substances that improve sports results and contribute to restoration after training.
  • For weight loss: They contain substances that are claimed to help reduce appetite, accelerate metabolism and burn fat. (It should be noted that the effectiveness of dietary supplements for weight loss is often not proved).

• By the source of the origin of the components:

  • Vegetable: The components are obtained from plants.
  • Animals: The components are obtained from animal sources.
  • Mineral: The components are obtained from mineral springs.
  • Synthetic: The components are synthesized chemically.
  • Microbial: The components are obtained from microorganisms.

It is important to understand that dietary supplements are not a replacement for full and balanced diet. They should be used only as an addition to the diet to replenish the deficiency of certain substances or maintain certain body functions. Before taking dietary supplements, it is recommended to consult a doctor or other qualified specialist.

Section 2: normative regulation of dietary supplements in different countries

The normative regulation of dietary supplements varies significantly in different countries, which affects the requirements for the production, sale and marketing of these products. Unlike drugs, dietary supplements are often regulated less strictly, which can create problems with quality, safety and efficiency.

• Russia: In Russia, the regulation of dietary supplements is carried out by the Federal Service for Supervision of Consumer Rights Protection and Human Welfare (Rospotrebnadzor). Bades are subject to state registration, which includes verification of compliance with sanitary and epidemiological requirements. Requirements for labeling, composition and safety of dietary supplements are regulated by the technical regulations of the Customs Union. Advertising of dietary supplements should contain a warning that they are not drugs.

• USA: In the United States, dietary supplements are regulated by the sanitary supervision of the quality of food and medication (FDA) in accordance with the Law on Food Addles, Health and Education (DSHEA) of 1994. DSHEA defines dietary supplements as products designed to add diet and containing vitamins, minerals, herbs or other plant substances, amino acids or concentrates, metabolites, components or extracts of these substances. Unlike drugs, FDA does not require preliminary approval of dietary supplements before their entry on sale. Manufacturers are responsible for ensuring the safety of their products, and FDA can only take measures after the product has entered the sale and security problems have been identified. The marking of dietary supplements should contain information about the composition, manufacturer and instructions for use. Manufacturers cannot make statements that dietary supplements are treated, diagnosed or prevented if these statements have not been approved by FDA.

• European Union (EU): In the EU, the regulation of dietary supplements is carried out at the level of individual member countries, but there are a number of pan-European directives and regulations regarding food safety, labeling and advertising. The European Power Safety Agency (EFSA) assesses the safety of food ingredients, including those used in dietary supplements. Some vitamins and minerals used in dietary supplements are subject to harmonization in relation to the maximum permissible levels. Advertising of dietary supplements should be true and not mislead consumers. Applications for health benefits should be scientifically justified and approved by EFSA.

• Canada: In Canada, dietary supplements, known as natural Health Products (NHPS), are regulated by the Ministry of Health of Canada (Health Canada) in accordance with the rules on natural health products (NHPR). NHPS should be assessed by safety, efficiency and quality before obtaining a permit for sale. Manufacturers must provide evidence confirming the declared properties of the product. NHPS marking should contain information about the composition, manufacturer, instructions for use and license number.

• Australia: In Australia, dietary supplements, known as complementary drugs (Complementary Medicines) are regulated by the therapeutic product (Therapeutic Goods Administration, TGA). Complete drugs are subject to assessment of safety, quality and effectiveness before obtaining permission to sell. TGA uses various levels of regulation depending on the risk associated with the product. Manufacturers must comply with the requirements for production, labeling and advertising.

Approach comparison:

In general, approaches to the regulation of dietary supplements differ in different countries. In the United States, regulation is less strict than in Europe, Canada or Australia. In the United States, manufacturers are responsible for ensuring the safety of their products, but FDA does not pre -assess. In Europe, Canada and Australia, regulation is more strict, and dietary supplements are subject to assessing safety, quality and efficiency before obtaining permission to sell.

Differences in regulatory regulation can lead to the fact that the same dietary supplement can be available in one country and prohibited in another. It can also affect the quality and safety of dietary supplements available in the market. It is important for consumers to realize these differences and carefully study information about dietary supplements before acquiring them.

Problems related to the regulation of dietary supplements:

• Insufficient rigor of regulation: In many countries, the regulation of dietary supplements is less strict than the regulation of drugs. This can lead to the fact that poor -quality and unsafe products fall into the market.
• Lack of preliminary assessment: In some countries, such as the USA, FDA does not preliminary assess the dietary supplements before their admission. This means that FDA can take measures only after the product has entered the sale and security problems have been identified.
• False statements: Bad manufacturers often make false or misleading statements about the health benefits of their products.
• Contamination: Bades can be polluted by heavy metals, pesticides or other harmful substances.
• Interaction with drugs: Bades can interact with drugs, which can lead to undesirable side effects.

Recommendations for consumers:

• Consult a doctor or other qualified specialist before starting dietary supplements.
• Choose dietary supplements from famous and reliable manufacturers.
• Read the label carefully and follow the instructions for use.
• Do not exceed the recommended dose.
• Tell your doctor about all the dietary supplements you accept.
• Be careful with dietary supplements who promise wonderful healing or quick weight loss.
• Remember that dietary supplements are not a replacement for full and balanced diet.

Section 3: Scientific evidence of the effectiveness of the most common dietary supplements

Assessment of the effectiveness of dietary supplements is a difficult task, since many factors can affect research results, including product quality, dosage, duration of admission, characteristics of subjects and research design. It is important to critically evaluate scientific data and take into account all the evidence, and not rely on individual research or advertising statements. Below is a review of scientific data on the effectiveness of some of the most common dietary supplements:

• Vitamin C: Vitamin C (ascorbic acid) is a powerful antioxidant and plays an important role in maintaining the immune system, wound healing and collagen formation.

  • Colds: Numerous studies have shown that regular intake of vitamin C does not prevent colds in most people, but can slightly reduce the duration and severity of symptoms. However, the effect is more pronounced in people undergoing intensive physical exertion (for example, in athletes).
  • Immunity: Vitamin C supports the function of immune cells and protects them from damage. Vitamin C deficiency can weaken the immunity and increase susceptibility to infections.
  • Cardiovascular diseases: Some studies have shown that high consumption of vitamin C may reduce the risk of cardiovascular diseases, but additional studies are needed to confirm these results.
  • Cancer: Vitamin C has antioxidant properties that can protect cells from damage caused by free radicals. Some studies have shown that high consumption of vitamin C is associated with a lower risk of certain types of cancer, but additional studies are needed.

• Vitamin D: Vitamin D is necessary for the health of bones, since it helps the body absorb calcium. It also plays an important role in maintaining the immune system, muscle function and nervous system.

  • Bone health: Vitamin D is necessary for the prevention of rickets in children and osteoporosis in adults. Taking vitamin D in combination with calcium can reduce the risk of bone fractures.
  • Immunity: Vitamin D plays an important role in the regulation of the immune system. Vitamin D deficiency is associated with an increased risk of infections, autoimmune diseases and certain types of cancer.
  • Cardiovascular diseases: Some studies have shown that vitamin D deficiency is associated with an increased risk of cardiovascular diseases, but additional studies are needed to confirm these results.
  • Depression: Some studies have shown that vitamin D intake can improve mood and reduce depression symptoms, especially in people with vitamin D.

• Omega-3 fatty acids: Omega-3 fatty acids are polyunsaturated fats that are important to the health of the cardiovascular system, brain and vision. The main types of omega-3 fatty acids are eicosapentaenic acid (EPA) and non-coshegexic acid (DHA), which are found in fish oil, and alpha-linolenic acid (ALA), which is found in vegetable oils.

  • Cardiovascular diseases: Omega-3 fatty acids reduce the level of triglycerides in the blood, reduce inflammation, reduce blood pressure and prevent blood clots. Numerous studies have shown that the intake of omega-3 fatty acids reduces the risk of heart attacks, strokes and sudden death from heart causes.
  • Brain: DHA is the main structural component of the brain and plays an important role in the development and functioning of the brain. Reception of omega-3 fatty acids can improve cognitive functions, memory and mood.
  • Vision: DHA is the main structural component of the retina and plays an important role in vision. Reception of omega-3 fatty acids can reduce the risk of age-related macular degeneration (VMD).
  • Inflammation: Omega-3 fatty acids have anti-inflammatory properties and can help reduce the symptoms of diseases such as rheumatoid arthritis.

• Probiotics: Probiotics are living microorganisms, which, when used in sufficient quantities, have a beneficial effect on the body. They are found in fermented products, such as yogurt and kefir, as well as in dietary supplements.

  • Intestinal health: Probiotics help restore the balance of intestinal microflora, improve digestion, reduce bloating and diarrhea.
  • Immunity: Probiotics stimulate the immune system and protect against infections.
  • Allergies: Some studies have shown that the intake of probiotics can reduce the risk of allergies in children.
  • Inflammatory intestinal diseases: Probiotics can help reduce the symptoms of inflammatory intestinal diseases, such as ulcerative colitis and Crohn’s disease.

• Glucosamine and chondroitin: Glucosamine and chondroitin are components of cartilage and are often used as dietary supplements for the treatment of osteoarthritis.

  • Osteoarthritis: The results of studies on the effectiveness of glucosamine and chondroitin in osteoarthritis are contradictory. Some studies have shown that they can help reduce pain and improve the function of the joints, while other studies have not found a significant effect. The effect may depend on the severity of the disease and individual characteristics of the patient.

• Creatine: Creatine is an amino acid that is mainly contained in the muscles. It is used as a dietary supplement to improve sports results and increase muscle mass.

  • Sports results: Creatine increases strength and endurance, especially with high -intensity exercises.
  • Muscle mass: Creatine helps to increase muscle mass when combined with strength training.
  • Brain function: Some studies have shown that creatine can improve brain function, especially memory and concentration.

• Plant extracts: The effectiveness of plant extracts varies greatly depending on the type of plant, the method of extraction and dosage. It is important to choose products from reliable manufacturers that provide standardized extracts with a certain content of active substances.

  • SOUTINATEA: It is often used for the prevention and treatment of colds. Some studies have shown that echinacea can reduce the duration and severity of the symptoms of colds, but additional studies are needed.
  • Ginkgo biloba: Used to improve memory and cognitive functions. Some studies have shown that ginkgo bilobe can improve the memory and concentration of attention in the elderly, but additional studies are needed.
  • Milk thistle: Used to maintain liver function. Proopsha contains silimarin, which has antioxidant and anti -inflammatory properties. Some studies have shown that milk thistle can help protect the liver from damage caused by toxins and alcohol.

Important comments:

• Individual variability: The effectiveness of dietary supplements can vary depending on the individual characteristics of a person, such as age, gender, state of health and genetics.
• Interaction with drugs: Bades can interact with medicines, so it is important to consult a doctor before taking dietary supplements, especially if you take any medicine.

• Dosage: It is important to observe the recommended dosage of dietary supplements, since taking high doses can lead to side effects.
• Do not replace good nutrition: Bades are not a replacement for full and balanced diet. They should only be used as an addition to the diet.

Section 4: Factors affecting the effectiveness of dietary supplements

The effectiveness of biologically active additives (dietary supplements) is not unambiguous and depends on many factors that must be taken into account when assessing their potential benefit.

• Quality product: The quality of Bad plays a decisive role in its effectiveness. Poor -quality products may contain incorrect ingredients, incorrect dosages, polluting substances or just fakes.

  • Source of ingredients: The quality of the ingredients used in dietary supplements can vary greatly depending on the source. For example, plant extracts may contain different amounts of active substances depending on the plant variety, growing conditions and processing method.
  • Production process: The production process can also affect the quality of the dietary supplement. Incorrect production methods can lead to loss of active substances or product pollution.
  • Independent testing: It is important to choose dietary supplements that have passed independent quality testing and cleanliness. Some organizations are testing dietary supplements and provide certificates of conformity.

• Dosage: The dosage of dietary supplements should be adequate to achieve the desired effect. A too low dose may not have any effect, and a too high dose can lead to side effects.

  • Individual needs: The optimal dosage of dietary supplements can vary depending on the individual needs of a person, such as age, gender, weight, health status and medications taken.
  • Scientific data: The dosage of dietary supplements should be based on scientific data. It is recommended to consult a doctor or other qualified specialist to determine the optimal dosage.

• Bioavailability: Bioavailability is a degree in which the active substance from the dietary supplement is absorbed into the blood and reaches its place of action in the body. Some substances have low bioavailability, which means that they are poorly absorbed in the intestines.

  • Output form: The form of producing dietary supplements can affect its bioavailability. For example, some substances are better absorbed in the form of capsules than in the form of tablets.
  • Simultaneous intake with food: Simultaneous intake of food with food can increase or reduce its bioavailability. Some dietary supplements are better absorbed when taking fatty foods, while others are on an empty stomach.

• Duration of admission: To achieve the desired effect, some dietary supplements must be taken for a long time. For example, to improve the condition of the joints with osteoarthritis, glucosamine and chondroitin must be taken for several months.

• Health status: Human health can affect the effectiveness of dietary supplements. For example, in people with diseases of the gastrointestinal tract, the absorption of nutrients can be impaired, which can reduce the effectiveness of dietary supplements.

• Interaction with drugs: Bades can interact with medicines, which can lead to undesirable side effects or reducing the effectiveness of drugs. It is important to inform your doctor about all the dietary supplements that you accept.

• Genetic factors: Genetic factors can affect the metabolism and effect of dietary supplements. For example, some people may have a genetic predisposition to a deficiency of certain vitamins or minerals, which can increase their need for dietary supplements.

• Life: Human lifestyle, such as diet, physical activity and smoking, can affect the effectiveness of dietary supplements. For example, people who do not adhere to a healthy diet can have a more pronounced nutrient deficiency, which can increase the efficiency of dietary supplements.

• Placebo effect: A placebo effect is a psychological effect in which a person experiences a health status only because he believes that he takes an effective medicine or supplement. A placebo effect can affect the results of dietary supplements, so it is important to conduct research with a control group receiving placebo.

Recommendations to increase the efficiency of dietary supplements:

• Choose quality products from reliable manufacturers.
• Follow the recommended dosage.
• Take dietary supplements in accordance with the instructions and recommendations of a doctor or other qualified specialist.
• Consider your individual needs and health status.
• Tell your doctor about all the dietary supplements you accept.
• Lead a healthy lifestyle.
• Do not rely only on dietary supplement to improve health. Full and balanced nutrition, regular physical exercises and rejection of bad habits are the basis of a healthy lifestyle.
