We increase immunity using dietary supplements: a detailed guide for choosing and applying
I. Immunity: Fundamentals and role in health
-
What is immunity? Immunity is a complex system of protecting the body from pathogenic agents, such as bacteria, viruses, fungi, parasites and toxins. It includes various organs, tissues, cells and molecules that work in agreement to detect, neutralize and eliminate threats. There are two main branches of immunity: congenital (non -specific) and acquired (specific).
-
Inborn immunity: This is the first line of defense of the body, providing an immediate but non -specific reaction to the invasion. Components of congenital immunity include:
- Physical barriers: Leather, mucous membranes, saliva, tears.
- Cells: Phagocytes (macrophages, neutrophils, dendritic cells), natural killers (NK cells), basophiles, eosinophils, fat cells.
- Molecules: Complement, cytokines (interferons, interleukins), acute -phase proteins.
Congenital immunity recognizes the general molecular patterns associated with pathogens (PAMPS) using pattern recognition receptors such as TLR (Toll-Like Receptors). Activation of PRRS launches a cascade of reactions leading to inflammation, phagocytosis and activation of acquired immunity.
-
Acquired immunity: This is a slower, but specific and long -term protection, which develops in response to contact with a specific antigen (foreign substance). The acquired immunity is divided into humoral and cellular.
- Humoral immunity: Mediated by b-lymphocytes, which are differentiated into plasma cells producing antibodies (immunoglobulins). Antibodies are associated with antigens, neutralizing them, opting (facilitating phagocytosis) and activating complement.
- Cellular immunity: It is mediated by T-lymphocytes, which are divided into two main types: CD4+ T-highpers and CD8+ cytotoxic T-lymphocytes (CTL). CD4+ T-highpers help b-lymphocytes produce antibodies and activate other immune cells. CTL destroy infected cells, recognizing antigens presented on the surface of cells in combination with MHC class I.
An important aspect of acquired immunological memory is an important aspect. After the first contact with the antigen, memory cells (B- and T-lymphocytes) are formed, which provide a faster and more strong immune response in re-contact with the same antigen. This is the basis of vaccination.
-
Factors affecting immunity: Many factors affect the state of the immune system, including:
- Age: The immune system is less effective in infants and elderly people.
- Nutrition: Insufficient nutrition, deficiency of vitamins and minerals weaken the immune system.
- Stress: Chronic stress suppresses the immune function.
- Dream: The lack of sleep reduces the activity of immune cells.
- Physical activity: Moderate physical activity strengthens the immunity, while excessive loads can weaken it.
- Chronic diseases: Diabetes, autoimmune diseases, HIV/AIDS weaken the immune system.
- Medicines: Some drugs (for example, corticosteroids, immunosuppressants) suppress immunity.
- Bad habits: Smoking and alcohol abuse negatively affect the immune system.
- Environmental factors: Air pollution, exposure to toxic substances.
-
Signs of weakened immunity: Symptoms of weakened immunity can be different and include:
- Frequent colds (more than 4-6 times a year).
- Long course of infections.
- Difficulties in healing wounds.
- Chronic fatigue.
- Recurrent herpetic infections.
- Allergic reactions.
- Problems with digestion.
II. Dietary supplements for immunity: what is it and how they work
-
Daistry definition: Biologically active additives (dietary supplements) are concentrates of natural or natural biologically active substances that are intended for direct intake or introduction into food products in order to enrich the diet with individual food or biologically active substances and their complexes, as well as to maintain the normal functioning of the body and prevent diseases. It is important to note that dietary supplements are not drugs and are not intended for the treatment of diseases.
-
The mechanisms of action of dietary supplements on immunity: Bades can maintain immunity in various ways:
- Providing the necessary nutrients: Many vitamins and minerals are cofactors of enzymes involved in immune reactions. The deficiency of these substances can disrupt the immune function.
- Antioxidant Protection: Oxidizing stress caused by free radicals can damage immune cells. Antioxidants neutralize free radicals and protect the cells from damage.
- Immunomodulation: Some dietary supplements can modulate the activity of immune cells, increasing their activity or regulating inflammatory processes.
- Support of intestinal microbiots: The intestinal microbiota plays an important role in immunity. Probiotics and prebiotics support a healthy microbiota, which positively affects the immune system.
-
Classification of dietary supplements for immunity: Bades aimed at maintaining immunity can be divided into several categories:
- Vitamins: Vitamin C, Vitamin D, Vitamin E, B vitamins B.
- Minerals: Zinc, selenium, iron, copper.
- Plant extracts: Echinacea, Ginseng, Cesnok, Imbing, Turmeric, Buzina.
- Probiotics and prebiotics: Lactobacteria, bifidobacteria, inulin, fruitoligosaccharides.
- Mushrooms: Reishi, Shiitaka, Metack.
- Omega-3 fatty acids: Eicopentenic acid (EPA), non -combusage acid (DHA).
- Amino acids: Glutamin, Argin.
- Other substances: Coenzyme Q10, beta-glucans, colostrum.
III. Vitamins and minerals to maintain immunity
-
Vitamin C (ascorbic acid): Vitamin C is a powerful antioxidant that protects immune cells from damage caused by free radicals. It also participates in the synthesis of collagen necessary to maintain the integrity of physical barriers (skin and mucous membranes). Vitamin C stimulates the activity of phagocytes, increases interferon products and enhances the proliferation of lymphocytes. The recommended daily dose of vitamin C is 75-90 mg, but to maintain immunity during the period of dose disease, it can be increased to 500-1000 mg per day. Sources of vitamin C: citrus fruits, kiwi, strawberries, pepper, broccoli, rosehip.
-
Vitamin D (calciferol): Vitamin D plays an important role in the regulation of the immune system. It binds to vitamin D (VDR) receptors, which are expressed on various immune cells, including T-lymphocytes, B lymphocytes and macrophages. Vitamin D stimulates the products of antimicrobial peptides (defensins), enhances phagocytosis and modulates inflammatory processes. Vitamin D deficiency is associated with an increased risk of infections, autoimmune diseases and cancer. The recommended daily dose of vitamin D is 600-800 IU (15-20 μg), but to maintain the optimal level in the blood, higher doses, especially in the winter period, may require. Sources of vitamin D: fatty fish (salmon, tuna, mackerel), egg yolks, enriched products (milk, juice). Vitamin D is also synthesized in the skin under the influence of sunlight.
-
Vitamin E (Tokoferol): Vitamin E is another powerful antioxidant that protects cell membranes from oxidative damage. It improves the function of T-lymphocytes, increases antibodies and stimulates the activity of NK cells. Vitamin E can also reduce inflammation. The recommended daily dose of vitamin E is 15 mg. Sources of vitamin E: vegetable oils (sunflower, olive, soybean), nuts, seeds, green leafy vegetables.
-
B vitamins B: B vitamins B (B1, B2, B3, B5, B6, B7, B9, B12) play an important role in energy exchange, DNA and RNA synthesis, as well as in the functioning of the nervous system. B vitamins deficiency can weaken the immune function. For example, vitamin B6 is necessary for the proliferation of lymphocytes and the synthesis of antibodies, and vitamin B12 is important for the functioning of the NK cells. Recommended daily doses of B vitamins vary depending on a specific vitamin. Sources of B vitamins B: meat, fish, eggs, dairy products, whole grain products, legumes, vegetables.
-
Zinc: Zinc is an important trace element necessary for the functioning of many enzymes involved in immune reactions. It plays a key role in the development and activation of T-lymphocytes, B lymphocytes and NK cells. Zinc also has antioxidant and anti -inflammatory properties. Zinc deficiency is associated with an increased risk of infections, slowed down by wound healing and impaired function of the immune system. The recommended daily dose of zinc is 8-11 mg. Sources of zinc: meat, seafood, nuts, seeds, legumes, whole grain products.
-
Selenium: Selenium is an important trace element necessary for the synthesis of selenoproteins, which have antioxidant and immunomodulating properties. Selenium is involved in the regulation of the activity of immune cells, increases antibodies and enhances protection against viral infections. Selenium deficiency is associated with an increased risk of infections, autoimmune diseases and cancer. The recommended daily dose of selenium is 55 μg. Sources of selenium: seafood, meat, nuts (especially Brazilian), seeds, whole grain products.
-
Iron: Iron is an important trace element necessary for the transport of oxygen and the functioning of many enzymes, including enzymes involved in immune reactions. Iron deficiency (iron deficiency anemia) can weaken the immune function, reduce the activity of phagocytes and lymphocytes, and increase susceptibility to infections. However, an excess of iron can also be harmful, as it contributes to the growth of bacteria. The recommended daily dose of iron is 8 mg for men and 18 mg for women (during pregnancy, the need for iron increases). Sources of iron: meat, poultry, fish, legumes, green leafy vegetables.
-
Copper: Copper is an important trace element necessary for the functioning of many enzymes involved in immune reactions. It is involved in the regulation of the activity of immune cells, the synthesis of antibodies and protection against oxidative stress. The shortage of copper can weaken the immune function. The recommended daily dose of copper is 900 mcg. Sources of copper: seafood, nuts, seeds, legumes, whole grain products.

V. Probiotics and prebiotics for immunity
-
Probiotics: Probiotics are living microorganisms that, when used in adequate quantities, have a favorable effect on the health of the owner. Probiotics are mainly represented by bacteria (lactobacteria, bifidobacteria) and yeast (Saccharmyces Boulardii). Probiotics support a healthy intestinal microbiota, which plays an important role in immunity. They compete with pathogenic microorganisms for nutrients and attachments, produce antimicrobials, stimulate the activity of immune cells and strengthen the barrier function of the intestine. Taking probiotics can reduce the risk of infections, improve digestion and strengthen the immune system. The dosage of probiotics varies depending on the strain and the form of release. It is recommended to choose probiotics with a high content of living bacteria (some kind of colony -forming units).
-
Prebiotics: Prebiotics are undigested food ingredients that stimulate the growth and activity of beneficial bacteria in the intestines. Prebiotics are mainly represented by fibers (inulin, fructoligosaccharides, galactooligosaccharides). The use of prebiotics contributes to the growth of probiotic bacteria, which positively affects the immune system and general health. Sources of prebiotics: onions, garlic, artichokes, bananas, chicory.
VI. Other dietary supplements for immunity
