Natural dietary supplements for immunity: Review

Part 1: Fundamentals of immunity and the role of dietary supplements

1. Immune system: complex body protection

   The immune system is a complex complex of cells, tissues and organs that protects the body from infections and other harmful effects. It works around the clock, finding and destroying pathogens, such as bacteria, viruses, fungi and parasites. In addition, the immune system plays an important role in the fight against cancer cells and maintaining overall health.

   1. Inborn immunity: The first line of protection acting immediately. It includes physical barriers (skin, mucous membranes), as well as cells, such as macrophages and neutrophils that absorb and destroy pathogens. Inflammation is an important part of congenital immunity that attracts immune cells to the place of infection. Natural killers (NK cells) recognize and destroy infected or tumor cells.

   2. Acquired immunity: It develops over time in response to the influence of certain pathogens. This type of immunity has “memory,” allowing the body to respond faster and more efficiently to repeated infections. Key components of the acquired immunity:

      • T-cells: Infected cells (cytotoxic T cells) are directly attacked or help to activate other immune cells (helper T cells). Regulatory T cells suppress the immune response, preventing autoimmune reactions.

      • B cells: They produce antibodies – proteins that are associated with pathogens and neutralize them or measure to destroy other immune cells. After contact with the pathogen, the B cells can turn into memory cells, providing long-term immunity.

   3. Dysfunction of the immune system: When the immune system does not function properly, various problems arise, including:

      • Immunodeficiency: The conditions in which the immune system is weakened, which makes a person more susceptible to infections. Immunodeficiency can be congenital (genetic) or acquired (for example, HIV/AIDS).

      • Autoimmune diseases: The conditions in which the immune system attacks the body’s own tissues. Examples: rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis.

      • Allergies: Excessive reaction of the immune system to harmless substances (allergens).

   4. Factors affecting immunity: Many factors can affect the function of the immune system, including:

      • Age: The immune system weakens with age (immunostation).

      • Diet: Insufficient consumption of nutrients can weaken the immune system.

      • Stress: Chronic stress can suppress the immune function.

      • Dream: The lack of sleep can negatively affect the immune system.

      • Physical activity: Moderate physical activity can improve the immune function, while excessive loads can suppress it.

      • Environment: The effect of toxins and pollutants can weaken the immune system.
