Bad for immunity: buy or not?

Bad for immunity: buy or not? A comprehensive analysis of efficiency, safety and choice

Section 1: Immune system: the foundation of health and its vulnerability

1. 1 Immunity: a multi -layer shield of the body.

   • Determination of immunity: a complex protection system against pathogens (bacteria, viruses, fungi, parasites) and abnormal cells (cancer).
   • Congenital immunity: the first line of defense, non -specific reaction (skin, mucous membranes, phagocytes, natural killers). Fast but less accurate.
   • Acquired immunity: a specific answer is formed throughout life in contact with antigens (vaccination, infections transferred). Slow, but more purposeful and has “memory”.
   • Cellular immunity: T-lymphocytes (T-highpers, T-killers, T-regulators) destroy infected cells or regulate the immune response.
   • Humoral immunity: B-lymphocytes produce antibodies (immunoglobulins), neutralizing pathogens in the blood and other body fluids.
   • The interaction of the components: a complex network of signal molecules (cytokines, interleukins, interferons) coordinates the work of various parts of the immune system.

2. 2 Factors weakening immunity.

   • Age: the immune system is aging (immunostation), the activity of T cells decreases, antibodies are reduced. Children also have an unripe immune system.
   • Chronic stress: increases the level of cortisol that suppresses immune functions.
   • Lack of sleep: violates the production of cytokines necessary for the immune response.
   • Improper nutrition: a deficiency of vitamins, minerals and other nutrients weakens immunity. Excess sugar and processed products contributes to inflammation.
   • Hypodynamia: low physical activity reduces the amount and activity of immune cells.
   • Chronic diseases: diabetes, cardiovascular diseases, autoimmune diseases, HIV/AIDS weaken immunity.
   • Harmful habits: smoking, alcohol abuse oppress the immune system.
   • Medicines: immunosuppressors (corticosteroids, cytostatics) suppress the immune response. Antibiotics destroy the useful intestinal microflora, which is important for immunity.
   • Adverse ecology: pollution of air, water and soil with toxic substances weakens immunity.
   • Vitamin D: vitamin D plays an important role in the regulation of the immune system.
   • Intestinal dysbiosis: impaired balance of intestinal microflora worsens the immune function.

3. 3 Signs of weakened immunity.

   • Frequent colds and infections: more than 4-6 colds per year, a long course of diseases.
   • Chronic fatigue: a constant feeling of fatigue, not passing after rest.
   • Slow wound healing: reduced tissue regeneration.
   • Rashes on the skin: eczema, dermatitis, herpes.
   • Problems with digestion: bloating, constipation, diarrhea.
   • Inflammation of the lymph nodes: an increase in lymph nodes, pain.
   • Frequent relapses of chronic diseases: exacerbation of chronic diseases.
   • Allergic reactions: strengthening of allergic reactions.
   • Autoimmune diseases: development or exacerbation of autoimmune diseases.

Section 2: Dad for immunity: what is it and why are they needed?

2. 1 Definition and classification of dietary supplements.

   • Dietary supplementation (biologically active additive): a concentrate of natural or identical to natural biologically active substances intended for direct intake or introduction into food products in order to enrich the ration with individual food or biologically active substances or complexes of such substances.
   • Forms of release: capsules, tablets, powders, solutions, teas, bars, etc.
   • Are dietary supplements allowed?: Are regulated by law, but such strict clinical trials as drugs do not pass.
   • Classification by composition:
     • Vitamins: vitamin C, vitamin D, B vitamins, vitamin E, vitamin A.
     • Minerals: zinc, selenium, iron, magnesium, copper.
     • Plant extracts: echinacea, ginseng, garlic, ginger, turmeric, elderberry, astral.
     • Probiotics and prebiotics: lactobacilli, bifidobacteria, inulin, fruitoligosaccharides.
     • Amino acids: L Lisine, L-lutamine, Arginine.
     • Mushrooms: Reishi, Shiitaka, Cordyceps.
     • Omega-3 fatty acids: fish oil, linseed oil.
     • Others: Coenzym Q10, Beta-Glyukans, Colostrum.

3. 2 The mechanisms of the action of dietary supplements positioned as immunomodulators.

   • Stimulation of immune cells: some dietary supplements (echinacea, beta-glucans) stimulate the activity of macrophages, natural killers and other immune cells.
   • An increase in antibodies: vitamin C, zinc and selenium participate in the synthesis of antibodies.
   • Anti-inflammatory effect: Kurkumin, omega-3 fatty acids have anti-inflammatory properties, reduce chronic inflammation, which weakens immunity.
   • Antioxidant protection: Vitamins C and E, selenium protect immune cells from damage to free radicals.
   • Support for intestinal microflora: probiotics and prebiotics improve the balance of intestinal microflora, strengthening immunity.
   • Regulation of the immune response: Vitamin D regulates the activity of immune cells, preventing excessive inflammatory reaction.
   • Increasing stress resistance: adaptogens (ginseng, rhodiola pink) increase the body’s resistance to stress, which weakens immunity.
   • Specific antiviral action: some plant extracts (an elderberry) have antiviral properties.

4. 3 Indications for the use of dietary supplements for immunity.

   • Frequent colds and infections: to reduce the frequency and severity of colds.
   • Chronic fatigue: to increase energy and reduce fatigue.
   • The recovery period after illness: to accelerate recovery and strengthen immunity.
   • During epidemics: for the prevention of infection infection.
