We strengthen immunity with the help of dietary supplements: full guidance for choosing and applying
Section 1: Fundamentals of immunity and its value
Immunity is a complex system of protecting the body from various threats, such as bacteria, viruses, fungi, parasites and even cancer cells. It includes many different organs, cells and molecules working in agreement to maintain health and prevent diseases. Our immune system constantly analyzes the internal and external environment, revealing potentially dangerous elements and neutralizing them. Effective immunity provides rapid and adequate response to pathogens, preventing the development of infections and minimizing their consequences.
1.1. The components of the immune system:
The immune system consists of two main branches: congenital and acquired immunity.
-
Inborn immunity: This is the first line of protection with which we are born. It acts quickly and nonspecific, that is, reacts to a wide range of threats without prior sensitization. Components of congenital immunity include physical barriers (skin, mucous membranes), cellular elements (macrophages, neutrophils, NK cells) and molecular mediators (cytokines, interferons). The skin, for example, serves as a physical barrier, preventing the penetration of pathogens into the body. The mucous membranes lining the respiratory tract and the gastrointestinal tract contain antimicrobials and contribute to the removal of microorganisms. Macrophages and neutrophils are phagocytes that absorb and destroy bacteria and other foreign particles. NK cells (natural killers) destroy infected cells and cancer cells. Cytokines and interferons are signal molecules that regulate the immune response and coordinate the actions of various immune cells.
-
Acquired immunity: This branch of immunity develops throughout life in response to contact with specific antigens. It has high specificity and remembers the antigens that he previously encountered, which allows him to more effectively respond with repeated meetings. The key components of the acquired immunity are B cells and T cells. B-cells produce antibodies that are associated with antigens and neutralize them or mark them to destroy other immune cells. T-cells are divided into several subtypes, including T-highpers that coordinate the immune response, and cytotoxic T-cells that destroy infected cells. The acquired immunity is formed after the infections or vaccination. Vaccination is the introduction of weakened or killed pathogens to stimulate an immune response without the development of the disease.
1.2. Factors affecting immunity:
The state of the immune system is affected by many factors, both internal and external.
-
Age: The immune system develops gradually in childhood and weakens with age. In children, immunity is not yet fully formed, so they are more susceptible to infections. In elderly people, the immune system becomes less effective, which leads to increased vulnerability to diseases and slow recovery.
-
Nutrition: A balanced diet, rich in vitamins, minerals and antioxidants, is necessary for the normal functioning of the immune system. The lack of nutrients can weaken the immunity and increase the risk of infections. Vitamins C, D, E, A, zinc, selenium and iron are especially important.
-
Stress: Chronic stress has a negative effect on the immune system, suppressing its functions and increasing susceptibility to diseases. Stress leads to the release of cortisol, a hormone that can weaken the immune response.
-
Dream: The lack of sleep also weakens the immune system. During sleep, the body produces cytokines that play an important role in the regulation of the immune response.
-
Physical activity: Moderate physical activity strengthens the immunity, improving blood circulation and stimulating the functioning of immune cells. However, excessive physical activity can suppress immunity.
-
Environmental condition: Environmental pollution, the effects of toxins and radiation can weaken the immune system.
-
Chronic diseases: Some chronic diseases, such as diabetes, cardiovascular diseases and autoimmune diseases, can negatively affect immunity.
-
Medicines: Some drugs, such as corticosteroids and immunosuppressants, can suppress the immune system.
1.3. Signs of weakened immunity:
Weakened immunity can be manifested by various symptoms, including:
- Frequent colds and infections.
- Long -term recovery after diseases.
- Increased fatigue and weakness.
- Chronic inflammatory processes.
- Problems with digestion.
- Allergic reactions.
- Skin rashes.
If you notice several of these symptoms in yourself, you should be a doctor to evaluate the state of your immune system.
Section 2: Bad to strengthen immunity: review and classification
Biologically active additives (dietary supplements) are products designed for additional nutrition and maintenance of health. They are not medicines and are not intended for the treatment of diseases, but can be useful to strengthen immunity and maintain overall health. It is important to note that before taking any dietary supplements, it is necessary to consult a doctor in order to verify their safety and the absence of contraindications.
2.1. Vitamins:
-
Vitamin C: A powerful antioxidant that supports the function of immune cells protects them from damage and stimulates antibodies. Vitamin C also plays an important role in the synthesis of collagen, which is necessary for the health of the skin and mucous membranes, which are physical barriers that protect the body from infections. The recommended daily dose of vitamin C is 75-90 mg for adults.
-
Vitamin D: It is important to regulate the immune response and maintain bone health. It participates in the activation of immune cells and promotes the production of antimicrobial peptides. Vitamin D deficiency can increase the risk of infections, especially respiratory. The recommended daily dose of vitamin D is 600-800 IU for adults, but can be increased depending on the level of vitamin D in the blood.
-
Vitamin E: An antioxidant that protects the cells from damage caused by free radicals. It also plays a role in maintaining the function of immune cells. The recommended daily dose of vitamin E is 15 mg for adults.
-
Vitamin A: It is necessary for the health of the mucous membranes, which are physical barriers that protect the body from infections. He also participates in the regulation of the immune response. The recommended daily dose of vitamin A is 700-900 mcg for adults.
-
B vitamins B: Important for the normal functioning of the immune system. Vitamin B6 is involved in the production of antibodies and supports the function of T-cells. Vitamin B12 is necessary for the health of the nervous system and blood formation, which also affects the immunity.
2.2. Minerals:
-
Zinc: He plays an important role in the functioning of immune cells, especially T-cells and NK cells. It also participates in the healing of wounds and maintaining the health of the skin. Zinc deficiency can weaken the immunity and increase the risk of infections. The recommended daily dose of zinc is 8-11 mg for adults.
-
Selenium: An antioxidant that protects cells from damage and supports the function of immune cells. He also participates in the regulation of the immune response. The recommended daily dose of selenium is 55 mcg for adults.
-
Iron: It is necessary for the normal functioning of immune cells and blood formation. Iron deficiency can weaken the immunity and increase the risk of infections. The recommended daily dose of iron is 8 mg for men and 18 mg for women.
-
Copper: Participates in the work of enzymes necessary for the functioning of the immune system.
2.3. Probiotics and prebiotics:
-
Probiotics: Living microorganisms that benefit health, improving the balance of intestinal microflora. A healthy intestine plays an important role in immunity, since it contains most of the body’s immune cells. Probiotics can improve the function of immune cells, reduce inflammation and protect against infections. Probiotics include lactobacilli and bifidobacteria.
-
Prebiotics: Interesting dietary fiber that serve as food for beneficial bacteria in the intestines. They contribute to the growth and reproduction of probiotics, improving intestinal health and immunity. The prebiotics include inulin, fruitoligosaccharides (phos) and galactooligosaccharides (state).
