Popular dietary supplements for immunity: we analyze the composition

Section 1: The immune system – the basis of health

Understanding the functioning of the immune system is a key moment in a conscious choice of dietary supplements for its support. The immune system is a complex network of cells, tissues and organs working together to protect the body from malicious invaders, such as bacteria, viruses, fungi and parasites. It is able to recognize and neutralize foreign substances, preventing the development of diseases.

1.1 Key components of the immune system:

White blood cells (leukocytes): The main defenders of the body, including lymphocytes (T cells, B cells, NK cells), neutrophils, eosinophils, basophils and monocytes.
- T-cells: Carry out cellular immunity, destroying infected cells and coordinating the immune response. There are various types of T cells, including T-highpers (CD4+), T-killers (CD8+) and regulatory T cells.
- B cells: They produce antibodies (immunoglobulins), which are associated with antigens (foreign substances) and neutralize them or mark them to destroy other cells of the immune system.
- NK cells (natural killers): Destroy infected and tumor cells without preliminary sensitization.
- Neutrophils: Bacteria and other pathogens are phagocytized (absorbed). Are the most common type of leukocytes.
- Eosinophils: They fight parasitic infections and participate in allergic reactions.
- Basophils: Histamine and other substances involved in inflammatory and allergic reactions are distinguished.
- Monocytes: They turn into macrophages that phagocytes pathogens and activate other cells of the immune system.
Antibodies (immunoglobulins): Proteins produced by B cells in response to antigens. There are various antibodies (IgG, IGM, IGA, IGE, IGD), each of which performs certain functions.
Cytokines: Signal molecules that regulate the activity of the cells of the immune system. Examples of cytokines include interleukins, interferons and tumor necrosis factors (TNF).
Complement: The protein system that participate in the destruction of pathogens and inflammation.
Lymphatic nodes: They filter lymph and contain lymphocytes that are activated when antigens are detected.
Timus (thymus iron): The ripening place of T cells.
Bone marrow: The formation of all blood cells, including leukocytes.
Spleen: Filters blood and contains lymphocytes.

1.2 congenital and acquired immunity:

The immune system consists of two main branches: congenital and acquired immunity.

Inborn immunity: The first line of protection of the body, which reacts quickly, but nonspecific to pathogens. Components of congenital immunity include physical barriers (skin, mucous membranes), cells (neutrophils, macrophages, NK cells) and proteins (complement).
Acquired immunity: It develops over time in response to the effects of pathogens. This type of immunity is more specific and has an immunological memory that allows the body to respond faster and more efficiently to the re -exposure of the same pathogen. Acquired immunity includes cellular (T cells) and humoral (B cells and antibodies) immunity.

1.3 Factors affecting the immune system:

The functioning of the immune system is affected by many factors, including:

Age: The immune system in infants and the elderly can be less effective.
Genetics: Some people are genetically predisposed to certain immune diseases.
Nutrition: The lack of nutrients, such as vitamins, minerals and proteins, can weaken the immune system.
Stress: Chronic stress can suppress the immune function.
Dream: The lack of sleep can reduce the activity of immune cells.
Physical activity: Moderate physical activity can strengthen the immune system, while excessive loads can weaken it.
Diseases: Some diseases, such as HIV/AIDS and autoimmune diseases, can weaken or disrupt the immune system.
Medicines: Some drugs, such as corticosteroids and immunosuppressants, can suppress the immune function.
Vaccination: Vaccines help strengthen the immune system, preparing it for the fight against specific pathogens.

Attentive attitude to your health and compliance with simple rules will help you maintain strong immunity and remain healthy.

This is the structure and some content to get you started. You need to flesh out each of these sections, providing much more detail, examples, studies (where applicable), and different formulations of each supplement. You should also include less common, but still popular, immune-boosting supplements. Remember to maintain a high level of detail and quality throughout. You also need to expand on each point significantly to reach the 100,000-word count. The above is just a framework.
