The best dietary supplements for immunity: comparison of prices and efficiency

Section 1: Understanding the immune system and its functioning

1. What is immunity? Immunity is a complex system of biological structures and processes within the body that protects it from diseases. It detects and destroys a wide range of threats, including bacteria, viruses, fungi, parasites and even its own body cells, which have become malignant or defective. Without a functioning immune system, the body would be constantly subject to infections and diseases.

2. The components of the immune system: The immune system consists of congenital and acquired immunity.

   • Inborn immunity: This is the first line of protection of the body that is present from birth. It includes physical barriers, such as leather and mucous membranes, as well as internal mechanisms, such as phagocytes (cells that absorb and destroy pathogens), natural killers (cells that destroy infected or cancer cells) and inflammation. Congenital immunity reacts quickly, but does not have specificity and memory.

   • Acquired immunity: This is an adaptive system that develops throughout life in response to the influence of various pathogens. It includes lymphocytes, such as B cells (producing antibodies) and T cells (destroying infected cells or coordinating immune response). The acquired immunity reacts more slowly than congenital, but has high specificity and immunological memory, which allows it to quickly and effectively respond to the re -impact of the same pathogen.

3. Factors affecting immunity: The functioning of the immune system is affected by many factors, including:

   • Age: The immune system of newborn and elderly people is less effective.

   • Nutrition: The lack of necessary nutrients, such as vitamins, minerals and proteins, can weaken the immune system.

   • Stress: Chronic stress suppresses the immune system.

   • Dream: The lack of sleep weakens immunity.

   • Physical activity: Moderate physical activity strengthens the immunity, while excessive training can weaken it.

   • Chronic diseases: Some diseases, such as diabetes and HIV, suppress the immune system.

   • Medication: Some drugs, such as corticosteroids, can weaken the immune system.

   • Bad habits: Smoking and excessive alcohol use weaken the immunity.

4. Signs of weakened immunity: Signs of weakened immunity may include:

   • Frequent colds and infections.
   • Slow wound healing.
   • Constant fatigue.
   • Problems with digestion.
   • Allergic reactions.
   • Skin rashes.

5. The role of dietary supplements in maintaining immunity: Biologically active additives (dietary supplements) can help support the immune system, providing the body with the necessary nutrients that may be absent in the diet. However, it is important to remember that dietary supplements are not a replacement for a healthy lifestyle and a balanced diet. They should be used as an addition to a healthy lifestyle.

Section 2: Key ingredients of dietary supplements for immunity

1. Vitamin C (ascorbic acid): Vitamin C is a powerful antioxidant that protects the cells from damage caused by free radicals. It also plays an important role in the functioning of immune cells, such as phagocytes and lymphocytes. Vitamin C is necessary for the synthesis of collagen, which is an important component of the skin and mucous membranes that provide a physical barrier against infections.

   • The mechanism of action: Vitamin C enhances the activity of immune cells, increases the production of antibodies and interferon (protein, which inhibits virus replication). It also reduces the inflammation and duration of the common cold.
   • Recommended dosage: The recommended daily dose of vitamin C is 75 mg for women and 90 mg for men. However, to maintain immunity during illness or stress, a higher dose may be required (up to 2000 mg per day).
   • Forms of vitamin C: Vitamin C is available in various forms, including ascorbic acid, sodium ascorbate, calcium ascorbate and liposomal vitamin C. Liposomal vitamin C has better bioavailability than other forms.
   • Side effects: When taking high doses of vitamin C, side effects can occur, such as diarrhea, nausea and abdominal pain.

2. Vitamin D (cholegalciferol): Vitamin D plays an important role in the regulation of the immune system. It affects the activity of immune cells, such as T cells and B cells, and contributes to the production of antimicrobial peptides that protect against infections. Vitamin D deficiency is associated with an increased risk of infectious diseases such as flu and pneumonia.

   • The mechanism of action: Vitamin D activates vitamin D (VDR) receptors on immune cells, which leads to the modulation of the immune response. It enhances congenital immunity and regulates the acquired immunity, preventing autoimmune reactions.
   • Recommended dosage: The recommended daily dose of vitamin D is 600 IU (15 μg) for adults. However, to maintain the optimal level of vitamin D in the blood, a higher dose may be required (up to 2000-4000 IU per day), especially in the winter months or for people with vitamin D.
   • Vitamin D forms: Vitamin D is available in two forms: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D3 is more effective in increasing the level of vitamin D in the blood than vitamin D2.
   • Side effects: When taking high doses of vitamin D, side effects can occur, such as nausea, vomiting, constipation and weakness.

3. Zinc: Zinc is an important trace element that is necessary for the functioning of the immune system. It is involved in the development and activation of immune cells, such as T cells, B cells and natural killers. Zinc also has antioxidant and anti -inflammatory properties. Zinc deficiency is associated with an increased risk of infectious diseases and slow healing of wounds.

   • The mechanism of action: Zinc is involved in enzymatic reactions necessary for the functioning of immune cells. It also regulates the expression of genes related to the immune response. Zinc contributes to the production of cytokines that coordinate the immune response.
   • Recommended dosage: The recommended daily dose of zinc is 8 mg for women and 11 mg for men. To maintain immunity during illness or stress, a higher dose may be required (up to 40 mg per day).
   • Forms of zinc: Zinc is available in various forms, including zinc gluconate, zinc sulfate, zinc citrate and zinc picoline. Zinc Picoline has better bioavailability than other forms.
   • Side effects: When taking high doses of zinc, side effects can occur, such as nausea, vomiting, diarrhea and abdominal pain. Long -term intake of high doses of zinc can lead to copper deficiency.

4. Selenium: Selenium is an important trace element that is necessary for the functioning of the immune system. It participates in antioxidant protection of cells and regulation of an immune response. Selenium promotes the production of glutathioneperoxidase, an enzyme that protects the cells from damage caused by free radicals. Selenium deficiency is associated with an increased risk of infectious diseases and autoimmune diseases.

   • The mechanism of action: Selenium is involved in the synthesis of selenoproteins, which play an important role in antioxidant protection and regulation of an immune response. It enhances the activity of immune cells and promotes the production of cytokines.
   • Recommended dosage: The recommended daily dose of selenium is 55 mcg for adults.
   • Selena forms: Selenium is available in various forms, including selenometionine, sodium selenite and sodium selenate. Seleenomeininin has better bioavailability than other forms.
   • Side effects: When taking high doses of selenium, side effects can occur, such as nausea, vomiting, diarrhea, hair loss and damage to the nervous system.

5. Probiotics: Probiotics are living microorganisms that bring health benefits when they are used in sufficient quantities. They improve intestinal health, strengthen the immune system and protect against infections. Probiotics help maintain the balance of intestinal microflora, which plays an important role in the immune response.

   • The mechanism of action: Probiotics compete with pathogenic bacteria for nutrients and the place of attachment in the intestines. They also stimulate immune cells in the intestines, such as T cells and B cells, and contribute to the production of antibodies. Probiotics strengthen the barrier function of the intestine, preventing the penetration of pathogens into the bloodstream.
   • Probiotics strains: There are many different probiotics strains, each of which has unique properties. Some of the most common probiotics strains include Lactobacillus Acidophilus, Bifidobacterium Bifidum, Lactobacillus Rhamnosus and Saccharmyces Boulardii.
   • Recommended dosage: The recommended dosage of probiotics depends on the strain and the product. It is usually recommended to take probiotics containing at least 1 billion CFO (colony -forming units).
   • Side effects: In some people, probiotics can cause side effects, such as bloating, gases and diarrhea. These side effects usually take place within a few days.

6. SOUTINATEA: Echinacea is a plant that is traditionally used to strengthen the immune system and combat infections. It contains active compounds that stimulate immune cells, such as phagocytes and natural killers. Echinacea can help reduce the duration and severity of a cold and influenza.

   • The mechanism of action: Echinacea stimulates the production of interferon, protein, which inhibits viruses replication. It also increases the activity of phagocytes that absorb and destroy pathogens.
   • Echinacea forms: Echinacea is available in various forms, including extracts, capsules and tea.
   • Recommended dosage: The recommended dosage of echinacea depends on the form and product.
   • Side effects: In some people, echinacea can cause side effects, such as nausea, dizziness and allergic reactions.

7. Elder (Sambucus nigra): Buzina is a plant that contains antioxidant and antiviral compounds. Buzina extract can help reduce the duration and severity of a cold and influenza.

   • The mechanism of action: Buzina contains anti -vocals, which are powerful antioxidants. It also contains compounds that inhibit the attachment of viruses to the cells of the body.
   • Busyn forms: Buzina is available in various forms, including extracts, syrups, candies and capsules.
   • Recommended dosage: The recommended bousin dosage depends on the shape and product.
   • Side effects: In some people, Buzin can cause side effects, such as nausea and diarrhea.

8. Reishi mushrooms, Shiitaka and Metack: These mushrooms contain beta-glucans, which are polysaccharides that stimulate the immune system. They can increase the activity of immune cells, such as natural killers and macrophages.

   • The mechanism of action: Beta-glucans are associated with receptors on immune cells, activating them and enhancing their activity. They also stimulate the production of cytokines that coordinate the immune response.
   • Forms of mushrooms: These mushrooms are available in various forms, including extracts, capsules and powders.
   • Recommended dosage: The recommended dosage depends on the shape and product.
   • Side effects: In some people, these mushrooms can cause side effects, such as stomach disorder.
