Literation dietary supplements: efficiency and safety

Literation dietary supplements: efficiency and safety

Section 1: Understanding dietary diet

Bades, or biologically active additives, positioned as means for losing weight, are a variety of products of products that promise to help in weight loss. Their popularity is due to the desire for quick and easy solutions in the fight with excess weight, however, the effectiveness and safety of these additives often cause doubts and require careful study.

1. 1 Definition and classification of dietary supplements for weight loss:

Bades are concentrates of natural or identical to natural biologically active substances intended for direct intake with food or introduction into food products. They are not drugs and are not intended for the treatment of diseases. Dietary supplements for weight loss are classified depending on their proposed mechanism of action, ingredient composition and target audience. The main categories include:

• Thermogenics: Contain substances that stimulate thermogenesis (heat production), such as caffeine, synephrine, green tea extract. It is assumed that they accelerate metabolism and contribute to the burning of calories.
• Fat blockers: They contain substances that prevent the absorption of fats in the intestines, for example, chitosan, orlistat (released according to the recipe, but sometimes faked and sold as dietary supplements).
• Carbohydrate blockers: Contain substances that prevent the absorption of carbohydrates, for example, white beans extract.
• Suppliers of appetite: Contain substances that cause a feeling of satiety or reduce appetite, for example, glucomannan, psillium.
• Diuretics (diuretics): Contain substances that increase fluid elimination from the body. Used to temporarily reduce weight due to water loss. Dangerous for prolonged use.
• Laxatives: Contain substances that stimulate intestinal motility and accelerate the excretion of the contents of the intestine. Used to temporarily reduce weight due to intestinal cleansing. Dangerous for prolonged use.
• Metabolic stimulants: They contain substances that are claimed, accelerate metabolism and contribute to fat burning, for example, L-Carnitine, Coenzyme Q10.
• Vitamin-mineral complexes: Designed to replenish the deficiency of vitamins and minerals, which can occur with limiting the calorie content of nutrition.

1. 2 Slimming dietary supplement:

Bad regulation differs significantly from the regulation of drugs. In most countries, dietary supplements are not subject to the same strict quality and safety control as medicines.

• Russian Federation: In Russia, dietary supplements are subject to state registration in Rospotrebnadzor. During registration, the product compliance with sanitary and epidemiological standards and safety requirements is checked. However, the effectiveness of dietary supplements is not evaluated.
• 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. Dietary supplement manufacturers are not required to prove the safety or efficiency of their products before they are putting on the market. FDA can only take measures if the product is recognized as unsafe after its entry into the market.
• European Union: In the EU, dietary supplements are regulated at the level of individual member states. There are general rules regarding the safety of food products, but there are no single requirements for registration and evaluating the effectiveness of dietary supplements.

This means that consumers should be especially careful when choosing a dietary diet and carefully study information about the product, manufacturer and possible side effects.

1. 3 Marketing strategies and producer promises:

D FAA manufacturers for weight loss often use aggressive marketing strategies to attract the attention of consumers. They make loud statements about quick and mild results that do not require significant efforts from the consumer.

• Using “natural” ingredients: Manufacturers often emphasize that their products contain only natural ingredients, which creates the impression of safety and efficiency. However, “natural” does not always mean “safe”. Many plant components can cause side effects and interact with drugs.
• Reviews and “Success Stories”: Manufacturers often publish reviews and “success stories” from allegedly satisfied customers. These reviews are often staged or based on inaccurate information.
• Using medical terms: Manufacturers can use complex medical terms to create the impression of the scientific validity of their products. However, these terms are often used incorrectly or mislead consumers.
• Limited promotion time: Manufacturers often use the tactics of the “limited time of action” to push consumers to a quick purchase.
• The emphasis on the lack of side effects: Manufacturers often declare the absence of side effects, which is a false statement, since any active substances can cause an individual reaction of the body.

Consumers should critically evaluate the marketing statements of dietary supplements for weight loss and not believe the promises of quick and easy results without effort. It is important to remember that an effective and safe weight loss requires an integrated approach, including a balanced diet, regular physical exercises and consulting a doctor or a nutritionist.

Section 2: Ingredients in dietary supplements for weight loss: efficiency and safety

Many dietary supplements for weight loss contain a wide range of ingredients, which are claimed to help reduce weight. However, the effectiveness and safety of these ingredients is often not confirmed by scientific research or have limited evidence. It is important to carefully study the composition of dietary supplements and understand potential risks associated with each ingredient.

2. 1 Thermogenics:

Thermogenics are substances that are claimed to accelerate metabolism and contribute to the burning of calories by increasing thermal products in the body.

• Caffeine: Caffeine is a stimulant of the central nervous system that can increase energy, improve concentration and accelerate metabolism. In moderate doses, caffeine is considered safe, but high doses can cause anxiety, insomnia, heartbeat, an increase in blood pressure and gastrointestinal disorders. Caffeine can interact with some drugs.
• Green tea extract (EGCG): Green tea extract contains polyphenols known as catechins, including Epagallocatechin Gallat (EGCG). EGCG can have a thermogenic effect and promote fat oxidation. In general, green tea extract is considered safe, but high doses can cause nausea, stomach disorder and liver damage in some people.
• Sinefrin (Gorky Orange Extract): Sinefrin is a stimulant similar to ephedrine, which was previously used in dietary supplements, but was prohibited due to serious side effects. Sinefrin can increase blood pressure and heart rate, especially in combination with caffeine. It can be dangerous for people with cardiovascular diseases.
• Capsaicin (red pepper extract): Capsaicin is an active component of red pepper, which can increase thermogenesis and reduce appetite. Capsaicin can cause burning in the stomach, diarrhea and other gastrointestinal disorders.
• Yohimbine: Yohimbine is an alpha-2 adreno-shock, which is claimed to help burning fat, especially in problem areas. Yochimbin can cause anxiety, increased blood pressure, heartbeat and other side effects. It is contraindicated in people with cardiovascular diseases, anxious disorders and mental illness.

2. 2 Fat blockers:

Fat blockers are substances that prevent the absorption of fats in the intestines, thereby reducing the number of calories entering the body.

• Hitosan: Chitosan is a polysaccharide obtained from crustacean shells. It is associated with fats in the digestive tract, preventing their absorption. Chitosan can cause gastrointestinal disorders, such as bloating, gases and diarrhea. It can also reduce the absorption of fat -soluble vitamins (a, d, e, k). People with allergies for seafood should avoid the use of chitosan.
• Orlistat: Orlistat is a drug that is released according to the prescription that blocks the enzyme lipase necessary for splitting fats in the intestines. It can cause fatty diarrhea, fecal incontinence and other gastrointestinal disorders. Orlistat can also reduce the absorption of fat -soluble vitamins. The illegally sold orlistat issued for dietary supplements may contain impurities and be dangerous to health.

2. 3 Carbohydrate blockers:

Carbohydrate blockers are substances that prevent the absorption of carbohydrates in the intestines, thereby reducing the number of calories entering the body.

• White beans extract: White beans extract contains alpha-amylase inhibitors, the enzyme necessary for the splitting of starch. It can reduce the suction rate of carbohydrates and reduce the glycemic food index. White beans extract can cause gastrointestinal disorders, such as bloating and gases.

2. 4 Suppliers of appetite:

Suppressors of appetite are substances that cause a feeling of satiety or reduce appetite, thereby reducing the consumption of calories.

• Glucomanan: Glucomannan is a soluble dietary fiber obtained from the roots of the cowing plant. It absorbs water and forms a gel in the stomach, creating a feeling of satiety. Glucomannan can cause bloating, gases and constipation. It is important to use glucomannan with a lot of water to avoid clogging of the esophagus.
• Psillium: Psillium is a soluble dietary fiber, obtained from the husk of plantain seeds. It absorbs water and increases the volume of the contents of the intestine, stimulating peristalsis and causing a feeling of satiety. Psychillium can cause bloating, gases and constipation. It is important to use a psillium with a lot of water.
• 5-HTP (5-hydroxyryptophan): 5-HTP is an amino acid, which is the predecessor of serotonin, a neurotransmitter participating in the regulation of appetite and mood. An increase in serotonin levels can reduce appetite. 5-HTP can cause nausea, vomiting, diarrhea and other gastrointestinal disorders. It can also interact with some drugs, including antidepressants.

2. 5 Diuretics and laxatives:

Diuretics and laxatives are substances that increase the elimination of fluid and intestinal contents from the body. They do not contribute to a real weight loss, but only lead to a temporary loss of water and a decrease in intestinal volume. Long -term use of diuretics and laxatives can be dangerous to health.

• Diuretics: Diuretics increase fluid elimination from the body, which can lead to dehydration, electrolyte imbalance (especially potassium) and heart rhythm disorders.
• Laxatives: The laxatives stimulate intestinal motility and accelerate the excretion of the contents of the intestine. Long -term use of laxatives can lead to dependence, impaired intestinal function, loss of electrolytes and dehydration.

2. 6 Other ingredients:

• L-Carnitin: L-carnitine is an amino acid that is involved in the transport of fatty acids in mitochondria for oxidation. It is alleged that L-carnitine can contribute to fat burning, but scientific evidence of this is limited. L-carnitine can cause nausea, vomiting, diarrhea and an unpleasant smell of the body.
• Chrome picoline: Chrome Picolinate is a form of chromium, which is claimed, can improve insulin sensitivity and reduce the appetite for sweets. Scientific evidence of the effectiveness of Picoline chromium in weight loss is limited. Chrome Picolinate can cause headache, nausea and other side effects.
• Conjugated linoleic acid (CLA): CLA is fatty acid, which is claimed to help burning fat and increase muscle mass. Scientific evidence of CLA efficiency in weight loss is contradictory. Cla can cause gastrointestinal disorders.

Section 3: Efficiency of dietary supplements for weight loss: Scientific data

The effectiveness of dietary supplements for weight loss is the subject of numerous scientific research. In general, scientific data indicate that most dietary supplements for weight loss do not have significant efficiency in the long term. Some dietary supplements can have a moderate effect on weight loss, but these effects are often insignificant and do not have clinical significance.

3. 1 Analysis of scientific research:

Many studies for weight loss have disadvantages, such as small samples, short duration, lack of a control group or the bias of researchers. This makes it difficult to obtain reliable conclusions about the effectiveness of these products.

• Meta-analyzes and systematic reviews: Met-analyzes and systematic reviews combine the results of several studies to get a more accurate assessment of dietary supplements. Many meta-analyzes show that most dietary supplements do not have significant efficiency.
• Randomized controlled studies (RCTs): RCTs are the “gold standard” of scientific research. In RCTs, participants are randomly distributed into groups that receive either active substance (dietary supplement) or placebo (dummy). Comparison of the results in these groups allows you to evaluate the effectiveness of the active substance. Many RCT dietary supplements do not show significant advantages compared to placebo.

3. 2 Comparison with placebo:

An important aspect of assessing the effectiveness of dietary supplements for weight loss is comparison with placebo. A placebo effect is an improvement in the state of health, which occurs as a result of the expectation of a positive result, and not from the active substance itself. Many studies show that dietary supplements for weight loss do not have a more pronounced effect than a placebo.

3. 3 Long -term effectiveness:

Even if dietary supplements for weight loss have some influence on weight loss in the short term, it is important to take into account their long -term efficiency. Many people who take dietary supplements for losing weight return to their original weight after the termination of additives. This is due to the fact that dietary supplements do not solve the main problem – unhealthy food habits and insufficient physical activity.

3. 4 Individual differences:

The effectiveness of dietary supplements can vary depending on the individual characteristics of the body, such as genetics, metabolism, health status and lifestyle. Some people may experience a more pronounced effect of taking dietary supplements than others. However, this does not mean that dietary supplements are effective for everyone.

3. 5 The importance of an integrated approach:

It is important to understand that dietary supplements for weight loss are not a “magic tablet.” Effective and safe weight loss requires an integrated approach, including:

• Balanced nutrition: The use of healthy and varied foods rich in fruits, vegetables, whole grain products and low -fat sources of protein.
• Regular physical exercises: Playing sports or other physical activity of at least 150 minutes a week of moderate intensity or 75 minutes per week of high intensity.
• Life change change: Making changes to your lifestyle, such as sufficient sleep, stress management and rejection of bad habits.
• Consultation with a doctor or nutritionist: Obtaining individual recommendations for nutrition and physical exercises from a qualified specialist.

Literation dietary supplements can only be considered as an auxiliary tool in a comprehensive weight loss program, and only after consulting a doctor.

Section 4: safety dietary supplement for weight loss: potential risks and side effects

4. 2 Interaction with drugs:

Dietary dietary supplements can interact with drugs by changing their effectiveness or enhancing side effects. It is important to inform your doctor about all the dietary supplements that you take, especially if you take drugs according to the prescription.

• Anticoagulants (thinning blood): Some dietary supplements, such as vitamin E and fish oil, can enhance the effect of anticoagulants, increasing the risk of bleeding.
• Antidepressants: Some dietary supplements, such as 5-HTP and St. John’s wort, can interact with antidepressants, causing serotonin syndrome.
• Diabetes Medicines: Some dietary supplements, such as chrome picolinate, can affect blood sugar, requiring the dose of drugs for diabetes.
• Blood pressure medicines: Some dietary supplements, such as caffeine and synephrine, can increase blood pressure, reducing the effectiveness of drugs for blood pressure.

4. 3 Lack of quality control and safety:

Unlike drugs, dietary supplements are not subject to the same strict quality control and safety. This means that the composition of the dietary supplement may not correspond to the declared on the label, and they may also contain impurities, harmful substances or prohibited ingredients.

• Incorrect marking: Bad labels may contain inaccurate or misleading information about the composition, dosage and possible side effects.
• Pollution: Bades can be polluted by heavy metals, pesticides, bacteria or other harmful substances.
• Fakes: There are many fake dietary supplements on the market that may contain dangerous ingredients or not contain active substances.

4. 4 Special risk groups:

Some groups of people are at risk of side effects of weight loss. These groups include:

• Pregnant and lactating women: Literation dietary supplements are not recommended for pregnant and nursing women, as they can harm the child.
• Children and adolescents: Literation dietary supplements are not recommended for children and adolescents, as they can affect their growth and development.
• People with chronic diseases: People with chronic diseases such as cardiovascular diseases, diabetes, liver or kidney diseases should consult a doctor before the use of dietary supplements for weight loss.
• People taking medications: People taking drugs according to the prescription should consult a doctor before the use of dietary supplements for weight loss in order to avoid the interaction of drugs.

4. 5 Messages about adverse effects:
