Bades: harm to the immune system – detailed analysis
Section 1: Understanding the immune system and its complexity
The immune system is a complex network of cells, tissues, organs and processes that protect the body from diseases. It recognizes and destroys pathogens, such as bacteria, viruses, fungi and parasites, and also destroys damaged or abnormal cells inside the body. The immune system works at several levels, from physical barriers, such as leather and mucous membranes, to specialized cells and molecules that attack specific threats.
1.1. Inborn immunity:
Congenital immunity is the first line of the body’s defense. It acts immediately and is not specific, that is, reacts equally to all types of threats. Components of congenital immunity include:
- Physical barriers: Leather, mucous membranes, tears, saliva and gastric acid.
- Cells: Macrophages, neutrophils, NK cells (natural killers), basophils, eosinophils and dendritic cells.
- Squirrels: Complement, cytokines (for example, interferons), interleukins, and chemokins.
Macrophages, for example, are phagocytes that absorb and digest pathogens and cell garbage. Neutrophils are the most common white blood cells that are the first to arrive at the infection. NK cells destroy infected with viruses and tumor cells. Cytokins are signal molecules that regulate the immune response. Interferons, in particular, play an important role in the fight against viral infections.
1.2. Acquired immunity (adaptive immunity):
Acquired immunity is a more complex and specific form of protection. It develops over time in response to the effects of pathogens and creates immunological memory, allowing the body to faster and more efficiently fight future infections. The key players of the acquired immunity are lymphocytes: B cells and T cells.
- B cells: They produce antibodies (immunoglobulins) that are associated with antigens (unique molecules on the surface of pathogens) and neutralize them or marked to destroy other immune cells.
- T-cells: There are various types of T cells, including:
- T-highpers (CD4+): They help to activate B cells and other T cells, as well as coordinate the immune response.
- Cytotoxic T cells (CD8+): Curred by viruses and tumor cells kill.
- Regulatory T cells (Treg): They suppress the immune response to prevent autoimmune reactions and maintain immunological homeostasis.
The acquired immunity is divided into two main types:
- Humoral immunity: Mediated by antibodies produced by B cells. Effective against extracellular pathogens, such as bacteria and viruses located outside the cells.
- Cellular immunity: Mediated by T-cells. Effective against intracellular pathogens, such as viruses located inside the cells, as well as against tumor cells.
1.3. Regulation of the immune system:
The immune system must be carefully adjustable in order to effectively fight infections, without causing harm to the body’s own tissues. Dysfunction of the immune system can lead to various problems, such as:
- Immunodeficiency: The weakening of the immune system, making the body more susceptible to infections.
- Autoimmune diseases: The immune system attacks the body’s own tissues.
- Allergies: The immune system reacts excessively to harmless substances.
- Chronic inflammation: Constant inflammation that can damage tissues and organs.
The regulation of the immune system is carried out by the complex interaction of cytokines, regulatory T cells and other factors. Violation of this balance can have serious health consequences.
Section 2: What is dietary supplements (biologically active additives) and their composition
Biologically active additives (dietary supplements) are products designed to supplement the diet. They are produced in various forms, such as tablets, capsules, powders, liquids and bars. Bades may contain vitamins, minerals, herbs, amino acids, probiotics, enzymes and other substances.
2.1. Categories of dietary supplements:
Bades are classified according to various categories depending on their proposed action and composition:
- Vitamins and minerals: Contain the necessary nutrients, such as vitamin C, vitamin D, calcium, magnesium and zinc.
- Herbal additives: Contain plant extracts, such as echinacea, ginseng, and St. John’s wort.
- Amino acids: They contain amino acids that are building proteins, such as glutamine, creatine and BCAA.
- Probiotics: They contain living microorganisms, which are supposed to be beneficial for health, such as Lactobacillus and Bifidobacterium.
- Omega-3 fatty acids: Contain polyunsaturated fatty acids, such as EPA and DHA, which are found in fish oil.
- Antioxidants: Contain substances that protect the cells from damage by free radicals, such as vitamin E, vitamin C, and coenzyme Q10.
- Enzymes: They contain enzymes that help digest food, such as amylase, protease and lipase.
- Other additives: Contain various substances, such as collagen, glucosamine, and chondroitin.
2.2. Bad regulation:
The regulation of dietary supplements is significantly different from the regulation of drugs. In most countries, dietary supplements do not pass the same strict control as medicines. Manufacturers of dietary supplements are not required to prove the efficiency or safety of their products before it is launched on the market. This means that the quality, composition and dosage of dietary supplements can vary significantly.
2.3. Problems with the composition and quality of dietary supplements:
One of the main problems with dietary supplements is the lack of standardization and quality control. This can lead to the following problems:
- Inconsistency with the declared composition: The dietary supplement may contain the ingredients not indicated on the label, or contain the ingredients in quantities other than the declared.
- Pollution: Bad can be contaminated with heavy metals, pesticides, bacteria or other harmful substances.
- Interaction with drugs: Bades can interact with medicines by changing their effectiveness or causing side effects.
- Unconfirmed statements about the benefits: Dad manufacturers often make unreasonable health benefits that are not confirmed by scientific research.
Section 3: Potential damage to dietary supplements for the immune system
Despite the fact that some dietary supplements can have a positive impact on the immune system, many of them can be harmful, especially if certain diseases are incorrectly used.
3.1. Immunostimulators and the risk of autoimmune reactions:
Some dietary supplements are advertised as “immunostimulants”, that is, substances that increase the activity of the immune system. Although stimulation of the immune system can be useful in some cases, for example, with infections, it can also be dangerous, especially for people with autoimmune diseases.
- The risk of exacerbation of autoimmune diseases: Immunostimulators can provoke or aggravate autoimmune reactions when the immune system attacks the body’s own tissues. For example, echinacea, which is often used to strengthen immunity, can cause exacerbations in people with autoimmune diseases such as rheumatoid arthritis or systemic lupus erythematosus.
- Nonspecific stimulation of the immune system: Some immunostimulants can non -specific activate the immune system, which can lead to chronic inflammation and damage to tissues.
3.2. Immunosuppressors and an increase in the risk of infections:
Some dietary supplements can have an immunosuppressive effect, that is, suppress the activity of the immune system. This can be dangerous because it reduces the body’s ability to fight infections.
- Increased susceptibility to infections: Immunosuppressive dietary supplements can increase the risk of infection with bacterial, viral, fungal and parasitic infections.
- Weakening of the immune response to vaccination: Immunosuppressors can reduce vaccination, making a person less protected from the diseases from which he was vaccinated.
- Slow down by wound healing: Immunosuppression can slow down the healing of wounds and increase the risk of infectious complications.
3.3. Influence on the cytokine balance:
Cytokins are signal molecules that regulate the immune response. The imbalance of cytokines can lead to various problems, such as chronic inflammation, autoimmune diseases and immunodeficiency. Some dietary supplements can affect the cytokine balance, both positively and negatively.
- Prospective cytokines: Some dietary supplements can stimulate the production of pro-inflammatory cytokines, such as TNF alpha and IL-6, which can lead to chronic inflammation.
- Anti -inflammatory cytokines: Other dietary supplements can stimulate the production of anti-inflammatory cytokines, such as IL-10, which can have a protective effect.
- Balance violation: It is important that the cytokine balance is maintained normally. Excessive stimulation or suppression of the production of certain cytokines can be harmful.
3.4. The effect on cellular immunity:
Cellular immunity plays an important role in the fight against intracellular pathogens and tumor cells. Some dietary supplements can affect the function of T cells and NK cells, which are key components of cellular immunity.
- Reducing the activity of T cells: Some dietary supplements can suppress the activity of T cells, which can reduce the body’s ability to fight viral infections and tumors.
- Reducing the activity of NK cells: Other dietary supplements can suppress the activity of NK cells, which can increase the risk of tumors.
- Changing the balance of T-HELPERS: Some dietary supplements can change the balance between different types of T-Helper, such as Th1 and Th2, which can affect the nature of the immune response.
3.5. Influence on humoral immunity:
Humoral immunity plays an important role in the fight against extracellular pathogens, such as bacteria and viruses that are outside the cells. Some dietary supplements can affect the function of B cells and the production of antibodies.
- Reducing antibodies: Some dietary supplements can suppress antibodies, which can reduce the body’s ability to fight infections.
- Antibody type change: Other dietary supplements can change the type of antibodies produced, which can affect the effectiveness of the immune response.
- Risk Autoantitel: Some dietary supplements can stimulate the production of autoantibodies that attack the body’s own tissues.
3.6. Contamination and toxicity:
As already mentioned, dietary supplements can be polluted by heavy metals, pesticides, bacteria or other harmful substances. These pollution can have a toxic effect on the immune system and other organs.
- Heavy metals: Heavy metals, such as lead, mercury and cadmium, can suppress the immune function and increase the risk of various diseases.
- Pesticides: Pesticides can have an immunotoxic effect, reducing the activity of immune cells and increasing the risk of infections.
- Bacteria and fungi: Pollution of dietary supplements with bacteria and fungi can lead to infections and inflammation.
3.7. Individual sensitivity and allergic reactions:
Some people may have individual sensitivity or allergies to certain ingredients of dietary supplements. Allergic reactions can appear in the form of a skin rash, itching, edema, shortness of breathing and other symptoms. In severe cases, allergic reactions can be fatal.
- Allergens: Some dietary supplements, such as herbs, pollen and beekeeping products, are common allergens.
- Cross reactivity: In people with allergies to certain foods or plants, cross reactivity with dietary supplements may occur.
- Unknown allergens: Some dietary supplements may contain ingredients that are not indicated on the label, and which can cause allergic reactions.
Section 4: Examples of dietary supplements and their potential impact on the immune system

- Hygiene: Wash your hands with soap and water often.
Section 8: Research and scientific data on the influence of dietary supplements on the immune system
Further research is needed to fully understand the influence of dietary supplements on the immune system. Many studies are small and not controlled, which complicates conclusions. However, the available data indicate that some dietary supplements can have both a positive and negative effect on the immune system. It is important to evaluate scientific data to critically and consult a doctor before making any decisions on making dietary supplements.
Section 9: Bades and immunity in children
Bad for children should be used with particular caution. The immune system of children is in the process of development, and their body is more sensitive to side effects of dietary supplements. Before giving a child any dietary supplements, it is necessary to consult a pediatrician. Do not give children dietary supplements intended for adults. Always follow the recommended dosage for children.
Section 10: Bades and immunity in older people
In older people, the immune system is weakened, which makes them more susceptible to infections. Some dietary supplements can be useful for strengthening immunity in the elderly. However, it is important to consider that older people are more often found in chronic diseases and they take more drugs, which can increase the risk of interaction between dietary supplements with drugs. Before taking any dietary supplements, older people need to consult a doctor.
Section 11: dietary supplements and immunity in chronic diseases
People with chronic diseases, such as autoimmune diseases, immunodeficiency, diabetes and cardiovascular diseases, should be especially careful about receiving dietary supplements. Some dietary supplements can interact with the medicines that they take, or aggravate their condition. Before taking any dietary supplements, people with chronic diseases need to consult a doctor.
Section 12: dietary supplements and immunity during pregnancy and lactation
Pregnant and nursing women should avoid taking dietary supplements, if this is not recommended by a doctor. Many dietary supplements were not tested for safety during pregnancy and lactation. Some dietary supplements can be harmful to the child.
Section 13: Alternative drugs and immunity
Some people turn to alternative drugs such as homeopathy, acupuncture and traditional Chinese medicine, to strengthen immunity. However, the effectiveness of these methods is not proven by scientific research. It is important to remember that alternative drugs are not a replacement for traditional medicine.
Section 14: Legislation and regulation of dietary supplements in different countries
The legislation and regulation of dietary supplements differ significantly in different countries. In some countries, dietary supplements are regulated as medicines, and in others – as food. It is important to know how dietary supplements are regulated in your country in order to make reasonable decisions about their use.
Section 15: Conclusion: Caution and informed choice
The use of dietary supplements to strengthen the immune system is a question that requires caution and informed choice.
