Overview of the best dietary supplements for immunity on reviews

I. Introduction: understanding of immunity and the role of dietary supplements

Immunity is a complex system in the body, designed to protect against pathogens, viruses, bacteria, fungi and other harmful substances. It consists of various organs, cells and processes that work consistently to detect and neutralize threats. The key components of the immune system include:

• Inborn immunity: The first line of protection, including physical barriers (skin, mucous membranes), fagocytes (neutrophils, macrophages) and natural killers (NK cells). Congenital immunity provides an immediate but non -specific response to the invasion of pathogens.
• Acquired immunity: It develops over time, after contact with antigens (foreign substances). The cells of acquired immunity (T cells and B-cells) “remember” antigens and are able to respond more effectively with re-contact, forming immunity to specific diseases.
• Cytokines: Molecules transmitting signals between the cells of the immune system, coordinating the immune response.

Factors affecting immunity:

• Age: The immune system is less effective in infants and elderly people.
• Nutrition: The lack of nutrients weakens the immune function.
• Stress: Chronic stress suppresses the immune system.
• Dream: The lack of sleep reduces the activity of immune cells.
• Physical activity: Moderate physical activity strengthens the immunity, and excessive – can weaken it.
• Chronic diseases: Some diseases (for example, diabetes, HIV) weaken the immune system.
• Medicines: Some drugs (for example, corticosteroids) suppress immunity.

Dietary supplements (biologically active additives) – These are products designed to supplement the diet and maintain health. They contain various vitamins, minerals, herbs and other substances that can have a positive effect on the immune system. It is important to note that dietary supplements are not medicines and are not intended for the treatment of diseases. However, they can be useful to maintain the normal function of the immune system, especially with a deficiency of nutrients or during periods of increased risk of diseases.

II. Key components of dietary supplements for immunity and their action

Effective dietary supplements for immunity usually contain a combination of ingredients synergically affecting various aspects of immune function. Consider the main components and their mechanisms of action:

1. Vitamin C (ascorbic acid):

   • The mechanism of action: A powerful antioxidant protects cells from damage by free radicals. Participates in the synthesis of collagen necessary for the health of the skin and mucous membranes (physical barriers of the immune system). It stimulates the production and activity of leukocytes (immune cells). Enhances the production of interferon, protein, which helps fight viral infections.
