Top dietary supplements to strengthen immunity

Top Badov to strengthen immunity: a scientific view of supporting the body’s defenses

Section 1: Understanding the immune system and its importance

1. Immune system: complex protection

   • The immune system is a complex network of cells, tissues, organs and processes, designed to protect the body from pathogens (bacteria, viruses, fungi, parasites) and cancer cells.
   • She recognizes “its” and “alien” elements, neutralizing or destroying the latter.
   • An effective immune system is a key factor for health and longevity.

2. Types of immunity: congenital and acquired

   • Inborn immunity: The first line of protection represented by barriers (skin, mucous membranes), cells (macrophages, neutrophils) and proteins (complement). Reacts quickly, but nonspecific.
   • Acquired immunity: It develops after contact with pathogens or vaccines. It is characterized by the specificity and formation of immune memory (cell B and T). Allows the body to more effectively fight repeated infections.

3. Factors affecting the immune function

   • Age: With age, the immune system weakens (immunostation), which makes the elderly more susceptible to infections.
   • Nutrition: The lack of nutrients (vitamins, minerals, proteins) reduces the immune function.
   • Stress: Chronic stress suppresses the immune system due to the release of cortisol.
   • Dream: The lack of sleep violates the production of immune cells and cytokines.
   • Physical activity: Moderate physical activity strengthens the immunity, and excessive ones can weaken it.
   • Chronic diseases: Diabetes, autoimmune diseases and other chronic conditions can negatively affect the immune system.
   • Environmental factors: Air pollution, the effects of toxins and other harmful substances can weaken the immunity.
   • Medicines: Some drugs (immunosuppressors, corticosteroids) suppress the immune system.

4. Signs of weakened immunity

   • Frequent colds and infections (more than 2-3 times a year).
   • Slow wound healing.
   • Chronic fatigue.
   • Repeating herpetic rashes.
   • Digestive problems (diarrhea, constipation).
   • Allergic reactions.

Section 2: Review of key dietary supplements to support immunity

1. Vitamin C (ascorbic acid)

   • The mechanism of action: Antioxidant, protects the cells from damage by free radicals. Participates in the synthesis of collagen necessary for the health of the skin and mucous membranes (physical barriers of immunity). Stimulates the activity of leukocytes (cells of the immune system).
   • Scientific data: Studies have shown that vitamin C can reduce the duration and severity of a cold. He can also reduce the risk of pneumonia.
   • Dosage: Recommended daily dose-75-90 mg. To support immunity during the disease, the dose can be increased to 500-1000 mg per day. Divide the dose into several techniques, since vitamin C is poorly absorbed in large quantities.
   • Forms: Ascorbic acid, sodium ascorbate, liposomal vitamin C. Liposomal vitamin C has a higher bioavailability.
   • Cautions: High doses of vitamin C can cause stomach disorder, diarrhea and the formation of kidney stones in predisposed people.

2. Vitamin D (cholegalciferol)

   • The mechanism of action: It regulates the immune function, activating the genes involved in the immune response. It stimulates the production of antimicrobial peptides (defensins), which protect against infections. Improves the function of immune cells (macrophages, T cells).
   • Scientific data: Vitamin D deficiency is associated with an increased risk of infections of the upper respiratory tract, influenza and autoimmune diseases. Vitamin D intake can reduce the risk of developing these diseases.
   • Dosage: Recommended daily dose-600-800 IU. For people with vitamin D deficiency, a higher dose (2000-5000 IU) is required under the supervision of a doctor. The optimal level of vitamin D in the blood is 30-50 ng/ml.
   • Forms: Vitamin D3 (cholecalciferol) is more effective than vitamin D2 (ergocalciferol).
   • Cautions: Excessive doses of vitamin D can cause hypercalcemia (increased blood calcium), which can lead to nausea, vomiting, weakness and other problems.

3. Zinc

   • The mechanism of action: It is necessary for the development and functioning of immune cells (T cells, B cells, NK cells). Participates in the synthesis of DNA and RNA necessary for the division and growth of cells of the immune system. It has antioxidant properties.
   • Scientific data: Zinc deficiency weakens the immune function and increases the risk of infections. Taking zinc can reduce the duration and severity of a cold, especially if you start taking it in the first days of the disease.
   • Dosage: The recommended daily dose is 8 mg for women and 11 mg for men. During the disease, the dose can be increased to 30-50 mg per day, but not more than a few days.
   • Forms: Qing Picoline, zinc citrate, zinc gluconate. Zinc Picoline is considered the most well -adversified form.
   • Cautions: High doses of zinc can cause nausea, vomiting, diarrhea and copper deficiency. Long -term intake of high doses of zinc can suppress the immune function.

4. Selenium

   • The mechanism of action: An important component of antioxidant enzymes (glutathioneperoxidase), which protect the cells from damage by free radicals. Participates in the regulation of immune function, stimulating the activity of immune cells and the production of cytokines.
   • Scientific data: Selenium deficiency is associated with an increased risk of infections and cancer. Reception of selenium can improve the immune function and reduce the risk of developing certain diseases.
   • Dosage: Recommended daily dose – 55 μg. The maximum permissible dose is 400 mcg.
   • Forms: Seleenometionine, sodium selenite, sodium selenate. Seleenomeinine is considered the most well absorbed form.
   • Cautions: Excessive doses of selenosis can cause selenosis, which manifests itself in the form of nausea, vomiting, hair loss, damage to nails and nervous system.

5. Probiotics

   • The mechanism of action: Living microorganisms, which, when entering the body in sufficient quantities have a positive effect on health. Improve the composition of intestinal microflora, which plays an important role in the immune function. They stimulate the production of antibodies and immune cells in the intestines. Strengthen the intestinal barrier, preventing the penetration of pathogens into the blood.
   • Scientific data: Probiotics can reduce the risk of respiratory infections, diarrhea and other diseases. They can also improve the immune response to vaccines.
   • Dosage: The dose of probiotics is measured in the colony -forming units (CFU). The recommended dose is 1-10 billion on a day.
   • Strains: Lactobacillus Rhamnosus GG, Lactobacillus Acidophilus, Bifidobacterium Lactis. Different strains of probiotics have different effects on health.
   • Cautions: Probiotics are usually safe for most people, but in rare cases they can cause bloating, gas formation and diarrhea. People with weakened immunity should consult a doctor before taking probiotics.

6. Room sa

   • The mechanism of action: It stimulates the immune system, increasing the number of leukocytes (cells of the immune system) and activating their function. It has antiviral and anti -inflammatory properties.
   • Scientific data: Echinacea can reduce the duration and severity of a cold. It can also reduce the risk of respiratory infections.
   • Dosage: The dose depends on the form of echinacea (extract, tincture, capsule). It is recommended to follow the instructions on the package.
   • Forms: Echinacea extract of purple, narrow -leaved echinacea, echinacea pale.

7. Black Buzina (Sambucus Nigra)

   • The mechanism of action: It has antiviral properties, blocking the penetration of the virus into the cells. Contains antioxidants that protect the cells from damage to free radicals. Stimulates the immune system.
   • Scientific data: Black elderberry extract can reduce the duration and severity of influenza. It can also reduce the risk of respiratory infections.
   • Dosage: The dose depends on the shape of the black bezine (syrup, capsules, candies). It is recommended to follow the instructions on the package.
   • Forms: Extract of berries of an elderberry black.
   • Cautions: An immature berries of black bezins contain toxic substances that can cause nausea, vomiting and diarrhea. Only mature berries prepared properly should be used.
