Strengthening immunity using dietary supplements

Strengthening immunity using dietary supplements: detailed analysis and guidance

Section 1: The immune system — the basis of health

1. What is immunity?

   Immunity is a complex system of protecting the body from external and internal threats. It includes organs, tissues, cells and chemicals that work together to recognize and neutralize pathogens (bacteria, viruses, fungi, parasites) and other harmful substances. The immune system is also responsible for the destruction of damaged or cancer cells inside the body.

2. The components of the immune system:

   • Inborn immunity: This is the first line of protection of the body that reacts quickly and nonspecific to any threats. It includes physical barriers (leather, mucous membranes), chemical barriers (acidity of the stomach, lysozyme in tears), as well as immune cells, such as macrophages, neutrophils and natural killers (NK cells).
   • Acquired immunity: This is a more specific and slow type of immunity, which develops after contact with a certain antigen (a substance causing an immune response). It includes lymphocytes-B cells (are responsible for the production of antibodies) and T cells (destroy infected cells and help B cells).

3. How does the immune system work?

   The immune system works as a coordinated team, where each component fulfills its role. When the pathogen enters the body, congenital immunity reacts immediately, trying to destroy it. If this fails, acquired immunity is activated. B cells begin to produce antibodies that are associated with the pathogen and mark it for destruction. T-cells, in turn, destroy infected cells or help Bels in antibodies. After the infection is defeated, the immune system “remembers” the antigen, which allows it to quickly and effectively respond to re -infection.

4. Factors affecting immunity:

   The state of the immune system is affected by many factors, including:

   • Age: Immunity in newborns and elderly people is weaker than in adults.
   • Nutrition: The lack of nutrients, especially vitamins and minerals, weakens immunity.
   • 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 — weakens.
   • Diseases: Some diseases, such as HIV, diabetes and autoimmune diseases, weaken the immunity.
   • Medicines: Some drugs, such as corticosteroids and immunosuppressants, suppress the immune system.
   • Ecology: Environmental pollution negatively affects immunity.

5. Signs of weakened immunity:

   Signs of weakened immunity can be different, but the most common of them:

   • Frequent colds (more than 4-6 times a year).
   • Long course of diseases.
   • Slow wound healing.
   • Chronic fatigue.
   • Frequent relapses of herpes.
   • Increase in the lymph nodes.
   • Allergic reactions.
   • Problems with digestion.

Section 2: Dad for immunity: What is it and how they work?

1. What are dietary supplements (biologically active additives)?

   Biologically active additives (dietary supplements) are concentrates of natural or natural biologically active substances that are intended for direct intake with food or introduction into food products in order to enrich the ration with individual food or biologically active substances and their complexes, as well as to increase the body’s resistance to adverse environmental factors. Bades are not medicines and are not intended for the treatment of diseases.

2. Mechanisms for the action of dietary supplements for immunity:

   Dietrs for immunity can work in different ways:

   • Direct stimulation of immune cells: Some dietary supplements, such as echinacea and ginseng, stimulate the activity of immune cells, increasing their ability to destroy pathogens.

Section 3: Review of the most popular dietary supplements to strengthen immunity

1. Vitamin C (ascorbic acid): detailed analysis

   • The role in the immunity: Vitamin C plays a critical role in maintaining the immune system. It is a powerful antioxidant that protects immune cells from damage caused by free radicals. Vitamin C stimulates the production and function of leukocytes (white blood cells), especially neutrophils and lymphocytes, which are key players in the fight against infections. It also participates in the production of antibodies that neutralize pathogens. Vitamin C helps to strengthen the barrier function of the skin and mucous membranes, preventing the penetration of microorganisms into the body.

   • Research and evidence: Numerous studies confirm the positive effect of vitamin C on immunity. Met-analyzes show that regular intake of vitamin C can reduce the duration and severity of colds, especially in people undergoing intensive physical stress. Studies also show that vitamin C can reduce the risk of pneumonia and other respiratory infections.

   • Recommended dosages: The recommended daily dose of vitamin C for adults is 75 mg for women and 90 mg for men. To strengthen immunity during periods of increased risk of infections, dosage can be increased to 200-500 mg per day. In high doses (more than 1000 mg per day), vitamin C can cause side effects, such as stomach and diarrhea disorder.

   • Side effects and contraindications: Vitamin C is usually well tolerated, but in high doses can cause side effects. Contraindications include individual intolerance, increased blood coagulation and kidney disease. People with urolithiasis should consult a doctor before taking vitamin C.

   • The best forms of release: Vitamin C is available in various forms, including tablets, capsules, chewing tablets, powders and sparkling tablets. Liposomal vitamin C is considered one of the most effective forms, since it is better absorbed by the body.

2. Vitamin D (cholegalciferol): detailed analysis

   • The role in the immunity: Vitamin D plays an important role in the regulation of the immune system. It binds to vitamin D (VDR) receptors, which are present on many immune cells, including T cells, B cells and macrophages. Vitamin D modulates the activity of these cells, enhancing antimicrobial immunity and reducing the risk of developing autoimmune reactions. It stimulates the production of antimicrobial peptides, such as Katelicidin and defensins, which help destroy pathogens. Vitamin D also helps maintain the barrier function of the skin and mucous membranes.

   • Research and evidence: Vitamin D deficiency is associated with an increased risk of infections, autoimmune diseases and cancer. Studies show that vitamin D intake can reduce the risk of respiratory infections, including flu and COVID-19. Met-analyzes confirm that vitamin D additives can reduce the frequency and severity of acute respiratory infections, especially in people with vitamin D.

   • Recommended dosages: The recommended daily dose of vitamin D for adults is 600-800 IU (international units). For people with vitamin D deficiency or to strengthen immunity during periods of increased risk of infections, dosage can be increased to 2000-4000 IU per day. In high doses (more than 4000 IU per day), vitamin D can cause side effects, such as hypercalcemia (increased blood calcium levels).

   • Side effects and contraindications: Vitamin D is usually well tolerated, but in high doses can cause side effects. Contraindications include hypercalcemia, hypervitaminosis D and kidney disease. People with kidney diseases should consult a doctor before taking vitamin D.

   • The best forms of release: Vitamin D is available in two main forms: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D3 is considered a more effective form, as it is better absorbed by the body. Vitamin D is available in the form of tablets, capsules, liquid solutions and oil solutions.

3. Zinc: detailed analysis

   • The role in the immunity: Zinc is an important trace element necessary for the normal functioning of the immune system. It is involved in the development and activation of immune cells, such as T cells, B cells and NK cells. Zinc plays a role in the synthesis of DNA and RNA necessary for dividing and growth of immune cells. It also participates in the production of cytokines that regulate the immune response. Zinc has antioxidant properties and protects immune cells from damage caused by free radicals.

   • Research and evidence: The deficit of zinc is associated with an increased risk of infections, impaired immune function and a slowdown in wound healing. Studies show that zinc intake can reduce the risk of respiratory infections, especially in children and the elderly. Met-analyzes confirm that zinc supplements can reduce the duration and severity of colds.

   • Recommended dosages: The recommended daily dose of zinc for adults is 8 mg for women and 11 mg for men. To strengthen immunity during periods of increased risk of infections, the dosage can be increased to 15-25 mg per day. In high doses (more than 40 mg per day), zinc can cause side effects, such as stomach disorder, nausea and vomiting. Long -term intake of high doses of zinc can lead to copper deficiency.

   • Side effects and contraindications: Zinc is usually well tolerated, but in high doses can cause side effects. Contraindications include individual intolerance, kidney disease and copper deficiency.

   • The best forms of release: Zinc is available in various forms, including tablets, capsules, candies and liquids. Zinc in the form of citrate, gluconate and picoline is considered more well absorbed than zinc in the form of an oxide.
