Dietary supplements for immunity: strengthen body protection

Dietary supplements for immunity: strengthen body protection

Section 1: The immune system – the basis of health

  1. 1 What is immunity?

    Immunity is a complex system in the body that is responsible for recognizing and neutralizing foreign agents, such as bacteria, viruses, fungi, parasites and other potentially dangerous substances. It works as a domestic army, protecting us from diseases around the clock. There are different types of immunity:

    • Inborn immunity: This is the first line of defense with which we are born. It consists of physical barriers (leather, mucous membranes), chemical barriers (acidity of the stomach) and cells (phagocytes, NK cells), which nonspecific attack any foreign agents.
    • Acquired immunity: This type of immunity develops with time when the body encounters various pathogens. It includes cellular (T-lymphocytes) and humoral (b lymphocytes, antibodies) immunity, which are specifically aimed at certain pathogens and remember them for future protection.
    • Passive immunity: This is a temporary immunity received from another source, for example, from mother to child through placenta or breast milk, or by introducing antibodies.
  2. 2 How does the immune system work?

    The immune system functions as a complex network of interacting cells, tissues and organs. Key components include:

    • The cells of the immune system:

      • Lymphocytes (T cells, B cells, NK cells): They play a central role in acquired immunity, recognizing and destroying specific pathogens. T-cells are of different types: Helpers (help other immune cells), killers (destroy infected cells) and regulatory (suppress the immune response to prevent autoimmune reactions). B cells produce antibodies that neutralize pathogens and mark them for destruction. NK cells kill infected or tumor cells without prior sensitization.
      • Phagocytes (macrophages, neutrophils, dendritic cells): Seeing and digesting pathogens and cell garbage. Macrophages also play a role in activating T-cells. Dendritis cells present antigens of T-cells, initiating an adaptive immune response.
      • Basophils, eosinophils, mast cells: Participate in allergic reactions and the fight against parasites.
    • The organs of the immune system:

      • Bone marrow: It produces all blood cells, including immune cells.
      • Timus (thymus iron): The ripening place of T-lymphocytes.
      • Lymphatic nodes: They filter lymph and contain immune cells that are activated when pathogens are detected.
      • Spleen: He filters blood, removes old and damaged cells and contains immune cells that respond to antigens in the blood.
      • Tonsils and adenoids: Protect the upper respiratory tract from infections.
      • Payerovs Plashki: Lymphoid tissues in the small intestine that protect against intestinal infections.
    • Molecules of the immune system:

      • Antibodies (immunoglobulins): Proteins produced by b lymphocytes, which specifically bind to antigens and neutralize them.
      • Cytokines: Signal molecules that regulate the immune response. Interleukins (IL), interferons (IFN), tumor necrosis factor (TNF) – examples of cytokines.
      • Complement: The blood protein system, which enhances the immune response, destroys pathogens and promotes inflammation.

    With the invasion of the pathogen, the immune system launches a cascade of reactions. Congenital immunity reacts immediately, but nonspecific. If the pathogen cannot be destroyed by innate immunity, acquired immunity is activated. T-cells and B cells recognize the antigens of pathogen and launch a specific immune response, which includes the destruction of infected cells and the production of antibodies. After the infection passes, the immune system “remembers” the pathogen, and with repeated invasion reacts faster and more efficiently.

  3. 3 Factors affecting immunity

    Many factors can affect the function of the immune system. Some of the most important include:

    • Age: The immune system is the most powerful aged 20 to 40 years. With age, the immune function is reduced (immunostation), which makes people more susceptible to infections and other diseases. Children also have an unripe immune system and are more vulnerable to infections.
    • Nutrition: The lack of nutrients, such as vitamins (A, C, D, E, B6, B12, folic acid), minerals (zinc, selenium, iron, copper) and proteins, can weaken the immune system.
    • Stress: Chronic stress suppresses the immune function, increasing the risk of diseases. Stress causes the release of cortisol, which can inhibit the activity of immune cells.
    • Lack of sleep: The lack of sleep weakens the immune system, reducing the amount and activity of immune cells.
    • Physical activity: Moderate physical activity strengthens the immune system, and excessive physical activity can weaken it.
    • Environment: Air pollution, pesticides and other toxins can weaken the immune system.
    • Medical conditions: Some diseases, such as HIV/AIDS, diabetes, cancer and autoimmune diseases, weaken the immune system.
    • Medicines: Some drugs, such as corticosteroids and immunosuppressants, suppress the immune system.
    • Smoking: Smoking damages immune cells and increases the risk of infections.
    • Alcohol: Alcohol abuse weakens the immune system and increases the risk of infections.
    • Microbiotic intestinal: Healthy intestinal microbiota plays an important role in maintaining immunity. Dysbiosis (microbiotic balance) can weaken the immune system.

Section 2: Dietrs for immunity – review and principles of choice

  1. 1 What are dietary supplements?

    Dietary supplements (biologically active additives) are concentrates of natural or natural biologically active substances, designed for direct intake with food or introduction to food products in order to enrich the ration with individual food or biologically active substances and their complexes, as well as to increase the adaptive capabilities of the body to adverse environmental factors. Bades are not drugs and are not intended for the treatment of diseases. They are designed to maintain health and prevention of diseases.

  2. 2 Principles of choosing dietary supplements for immunity

    The choice of dietary supplements for immunity should be conscious and based on the following principles:

    • Evaluation of the state of the immune system: Before taking any dietary supplements, it is advisable to assess the state of your immune system. This can be done by consulting a doctor and taking blood tests that will show the level of immune cells and antibodies.
    • Definition of needs: It is necessary to determine which aspects of the immune system require support. For example, if a person often suffers from colds, dietary supplements may be useful to him that increase the activity of congenital immunity. If a person suffers from allergies, dietary supplements that regulate the immune response may be useful to him.
    • The choice of quality products: It is important to choose dietary supplements from reliable manufacturers with a good reputation and providing information about the quality and safety of their products. Pay attention to the availability of quality certificates (for example, GMP).
    • Study of the composition: It is necessary to carefully study the composition of the dietary supplement and make sure that it contains ingredients that are really effective for strengthening immunity. Bades with dubious or unproven ingredients should be avoided.
    • Consultation with a doctor: Before taking dietary supplements, you need to consult a doctor, especially if you have any diseases or take any medicine. The doctor will be able to evaluate your needs and recommend the most suitable dietary supplements.
    • Dosage compliance: It is necessary to strictly observe the dosage indicated on the package of the dietary supplement. Exceeding the dosage can be harmful to health.
    • Evaluation of effectiveness: After the start of taking dietary supplements, it is necessary to evaluate its effectiveness. If no positive changes are observed within a few weeks or months, you should stop taking the dietary supplement and consult a doctor.
    • Individual approach: The effectiveness of dietary supplements can vary depending on the individual characteristics of the body. What is effective for one person can be ineffective for another.
