The benefits and harm of dietary supplements for immunity

Section 1: Understanding the immune system and its importance

1. 1. Fundamentals of the immune system: The immune system is a complex network of cells, tissues and organs that protects the body from harmful external factors, such as bacteria, viruses, fungi and parasites. It consists of two main branches: congenital immunity and acquired immunity. Congenital immunity is the first line of protection that reacts quickly, but nonspecific. It includes physical barriers, such as leather and mucous membranes, as well as cells, such as macrophages and neutrophils that absorb and destroy pathogens. The acquired immunity develops over time and is more specific, directed against specific threats. It includes lymphocytes (T cells and B cells) that remember pathogens and provide long-term protection.
2. 2. Key components of the immune system:
      • Leukocytes (white blood cells): These cells are the main fighters with infections. They include neutrophils, lymphocytes, monocytes, eosinophils and basophils, each of which performs a certain function in an immune response.
      • Lymphocytes (T cells and B cells): T-cells destroy infected cells and regulate the immune response. B cells produce antibodies that neutralize pathogens.
      • Antibodies (immunoglobulins): These are proteins that are associated with antigens (molecules on the surface of pathogens) in order to neutralize them or noted for destruction by other immune cells.
      • Cytokines: These are signal molecules that regulate the immune response, stimulating or suppressing the activity of immune cells. Examples include interleukins, interferons and tumor necrosis factor (TNF).
      • Comlender: This is a protein system that helps antibodies and phagocytes (cells that absorb and digest pathogens) destroy microbes and damaged cells.
      • The organs of the immune system: These include bone marrow (where immune cells form), thymus (where T cells ripen), lymph nodes (where immune cells and antigens are found) and spleen (which filters blood and removes old or damaged cells).
3. 3. Factors affecting the immune system: Many factors can affect the function of the immune system, both positively and negatively.
      • Age: The immune system weakens with age (immunostation), making the elderly more susceptible to infections.
      • 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 weaken the immune system.
      • Physical activity: Moderate physical activity can strengthen the immune system, while excessive training can suppress it.
      • Chronic diseases: Diseases, such as diabetes, heart disease and autoimmune diseases, can weaken the immune system.
      • Medicines: Some drugs, such as corticosteroids and immunosuppressants, can suppress the immune system.
      • Toxins: The effect of toxins, such as air pollution and tobacco smoke, can weaken the immune system.
4. 4. Signs of a weakened immune system: There are several signs that may indicate a weakened immune system:
      • Frequent infections: Frequent colds, flu, sinusitis or other infections.
      • Slow wound healing: Cuts, scratches and other wounds heal more slowly than usual.
      • Fatigue: Constant fatigue that does not pass after rest.
      • Digestive problems: Frequent digestive problems, such as diarrhea, constipation or bloating.
      • Autoimmune diseases: The development of an autoimmune disease in which the immune system attacks the body’s own tissues.
      • Skin problems: Frequent skin rashes, itching or other skin problems.

Section 2: Dad for immunity: General review

2. 1. What are dietary supplements (biologically active additives)? Bades are products designed to supplement the diet. They contain vitamins, minerals, herbs, amino acids, probiotics and other substances. Bades are not medicines and are not intended for the treatment, diagnosis or prevention of diseases. They are designed to maintain health and well -being. The regulation of dietary supplements differs from the regulation of drugs, and they do not go through the same strict clinical trials.
3. 2. Dad market for immunity: trends and popularity: The market for immunity is huge and continues to grow. Consumers are looking for ways to strengthen their immune system, especially during periods of increased risk of infections. Popular ingredients in dietary supplements for immunity include vitamin C, vitamin D, zinc, echinacea, elderberry, garlic, probiotics and turmeric. The marketing of these products often emphasizes their alleged ability to “strengthen” immunity, “support” the immune function and “protect” from diseases. However, it is important to understand that not all dietary supplements are effective, and some can even be harmful.
4. 3. The mechanisms of the action of dietary supplements: theoretical and practical aspects: Theoretically, dietary supplements can support the immune system in several ways:
      • Providing the necessary nutrients: Vitamins and minerals, such as vitamin C, vitamin D, zinc and selenium, play an important role in immune function. Their deficiency can weaken the immune system. Bades can help replenish the deficiency of these nutrients.
      • Antioxidant Protection: Antioxidants, such as vitamin C, vitamin E and curcumin, can protect immune cells from damage caused by free radicals.
      • Modulation of the immune response: Some herbs and other substances, such as echinacea and an elderberry, can stimulate or regulate the immune response.
      • Support of intestinal microbiots: Probiotics can improve intestinal health, which is associated with the immune function. However, it is important to note that many of these mechanisms of action are confirmed only in laboratory research or animals. Clinical studies in humans often give mixed results.

Section 3: Review of popular dietary supplements for immunity

3. 1. Vitamin C (ascorbic acid):
      • The role in the immunity: Vitamin C is a powerful antioxidant that protects immune cells from damage. It is also necessary for the production and functioning of leukocytes, especially lymphocytes. Vitamin C promotes the formation of collagen, which is necessary to maintain the barrier function of the skin and mucous membranes.
      • Scientific data: Some studies show that vitamin C can reduce the duration and severity of a cold, especially in people who are subjected to intensive physical stress. However, other studies do not confirm these results.
      • Recommended doses and safety: The recommended daily dose of vitamin C is 75 mg for women and 90 mg for men. The upper permissible level of consumption is 2000 mg per day. High doses of vitamin C can cause stomach disorder, diarrhea and other side effects.
