Bad for immunity: the path to good health

1. Immunity: the protective system of the body

The immune system is a complex network of cells, tissues and organs working together to protect the body from diseases. It recognizes and destroys harmful microorganisms, such as bacteria, viruses, fungi and parasites, as well as cancer cells and other abnormal elements. Strong immunity is the key to health and longevity. When the immune system works efficiently, we get sick less, recover faster and feel energetic.

1.1 components of the immune system

• Bone marrow: It produces blood cells, including white blood cells that play a key role in the immune response.
• Timus (thymus iron): The organ where T-lymphocytes that are responsible for cellular immunity ripen.
• Spleen: He filters blood, removes damaged cells and participates in an immune response on infections.
• Lymphatic nodes: They filter lymph containing antigens and immune cells, activating the immune response.
• Tonsils and adenoids: Protect the respiratory tract from infections.
• Intestine: Contains a large population of immune cells and a microbiota that plays an important role in immune regulation.

1.2 types of immunity

• Inborn immunity: The first body of the body, including physical barriers (skin, mucous membranes), fagocytes (macrophages, neutrophils) and natural killers (NK cells). It reacts quickly, but does not have specificity and memory.
• Acquired immunity: It develops in response to the effects of antigens (foreign substances). It has specificity and memory, which allows the body to respond faster and more efficiently to repeated infections. The acquired immunity is divided into:
  • Active immunity: It is formed after an infection or vaccination.
  • Passive immunity: It is transmitted from the mother to the child through the placenta or breast milk, or introduced in the form of ready -made antibodies (for example, when the snake is bitten).

1.3 factors affecting immunity

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

• Age: The immunity of newborn and elderly people is weakened.
• Nutrition: The lack of vitamins, minerals and other nutrients weakens the immune system.
• Stress: Chronic stress suppresses the immune function.
• Dream: The lack of sleep negatively affects the immune response.
• Physical activity: Moderate physical activity strengthen the immunity, and excessive – weaken.
• Diseases: Some diseases, such as HIV infection, autoimmune diseases and cancer, suppress the immune system.
• Medicines: Some drugs, such as immunosuppressants, weaken the immune system.
• Environmental factors: Environmental pollution negatively affects immunity.
• Microbiotic intestinal: The state of the intestinal microbiota has a significant effect on the immune function.

2. Bades: Support for immunity from the inside

Biologically active additives (dietary supplements) are concentrates of natural or identical to natural biologically active substances, designed for direct intake or introduction into food products in order to enrich the ration with individual food or biologically active substances and their complexes. Bades are not medicines and are not intended for the treatment of diseases, but can be useful for maintaining health and strengthening immunity.

2.1 Why do I need dietary supplements for immunity?

In the modern world, when we are subject to stress, malnutrition and the effects of adverse environmental factors, the maintenance of immunity becomes especially important. Bades can help replenish the deficiency of the necessary nutrients and support the normal function of the immune system. They can be useful in the following cases:

• Prevention of colds: Bades can help strengthen immunity and reduce the risk of acute respiratory viral infections and influenza.
