Dietary supplements for immunity: how to strengthen health

Section 1: Immunity – Health foundation

1.1. What is an immune system?

The immune system is a complex network of cells, tissues and organs working together to protect the body from pathogens, such as bacteria, viruses, fungi and parasites. It recognizes and neutralizes these threats, and also removes damaged or abnormal cells. An effective immune system is a key factor in maintaining health and preventing diseases. Without a functioning immune system, the body would be extremely vulnerable to infections and other diseases.

1.2. The components of the immune system:

White blood cells (leukocytes): The main component of the immune system, including lymphocytes (T cells, B cells, NK cells), phagocytes (neutrophils, macrophages, monocytes) and other types of cells, each of which plays a certain role in an immune response.
- T-cells: There are pathogens and coordinate the immune response, destroy infected cells. They are divided into T-highpers (help other immune cells), T-killers (directly destroy infected cells) and regulatory T cells (control the immune response, preventing autoimmune reactions).
- B cells: They produce antibodies, specific proteins that are associated with antigens (molecules on the surface of pathogens) and neutralize them. After activation, the B cells turn into plasma cells that actively secrete antibodies, and memory cells that provide prolonged immunity.
- NK cells (natural killers): Destroy cells and cancer cells infected with virus without prior sensitization. They use various mechanisms, including the release of cytotoxic substances to kill target cells.
- Neutrophils: The most common type of leukocytes is the first to arrive at the infection and absorb (phagocytes) pathogens. They also emit cytokines that attract other immune cells and contribute to inflammation.
- Macrophages: Pathogens and cell garbage are phagocytized, and also represent antigens of T cells. They play an important role in activating the immune response and healing of the wounds.
- Monocytes: The predecessors of macrophages that migrate from blood to tissue and differentiate in macrophages.
Antibodies (immunoglobulins): Proteins produced by B cells in response to antigens. They bind to antigens and neutralize them, mark them to destroy phagocytes or activate the complement system. There are several classes of antibodies (IGG, IGM, IGA, IGE, IGD), each of which performs certain functions.
Cytokines: Signal molecules secreted by immune cells to coordinate the immune response. They regulate the growth, differentiation and activity of immune cells. Examples of cytokines include interleukins, interferons and tumor necrosis factors (TNF).
Complement system: A complex of proteins circulating in the blood, which is activated by antibodies or pathogens and leads to lysis (destruction) of cells, opsonization (margin for phagocytosis) and inflammation.
The organs of the immune system:
- Bone marrow: Place of formation of immune cells.
- Timus: The ripening place of T cells.
- Spleen: He filters blood, removes old and damaged cells, and also activates the immune response.
- Lymphatic nodes: They filter lymph containing antigens and immune cells, and activate the immune response.
- Tonsils and adenoids: Protect from infections coming through the mouth and nose.
- Leather: Physical barrier protecting against pathogens.
- Mucous membranes: Laying breathing, digestive and genitourinary tracts and contain immune cells.

1.3. Types of immunity:

Inborn immunity: The first line of protection of the body, providing an immediate, but non -specific response to pathogens. It includes physical barriers (leather, mucous membranes), cells (neutrophils, macrophages, NK cells) and proteins (complement).
Acquired immunity (adaptive immunity): It develops in response to the effects of pathogens and provides long -term protection. It includes B cells and T cells that recognize specific antigens and produce a specific immune response. The acquired immunity is divided into active immunity (develops after infection or vaccination) and passive immunity (transmitted by antibodies from mother to child or by introducing antibodies).

1.4. Factors affecting immunity:

Age: The immune system weakens with age.
Nutrition: Insufficient consumption of nutrients, especially vitamins and minerals, can weaken the immune system.
Stress: Chronic stress suppresses the immune function.
Dream: The lack of sleep weakens the immune system.
Physical activity: Moderate physical activity strengthens the immune system, but excessive physical activity can weaken it.
Smoking and drinking alcohol: These bad habits weaken the immune system.
Diseases: Some diseases, such as HIV/AIDS and autoimmune diseases, weaken the immune system.
Medicines: Some drugs, such as corticosteroids and immunosuppressants, weaken the immune system.
Environmental factors: Pollution of air and water can weaken the immune system.

1.5. Signs of weakened immunity:

Frequent colds and infections.
Slow wound healing.
Chronic fatigue.
Problems with digestion.
Skin rashes and allergies.

Section 2: The role of dietary supplements in strengthening immunity

2.1. 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 or introduction into food products in order to enrich the diet with individual food or biologically active substances and their complexes, or to maintain normal functional state of the body, as well as to reduce the risk of diseases. Bades are not drugs and are not intended for the treatment of diseases.

2.2. How dietary supplements can help strengthen immunity:

Bades can support the immune system, providing the body with the necessary nutrients that may not be in the diet or the need for which increases under certain conditions (for example, during illness, stress or intensive physical exertion). Some dietary supplements contain substances with immunomodulating properties that can stimulate or regulate the immune response. It is important to understand that dietary supplements are not a replacement for a healthy lifestyle and a full nutrition, but only with addition to them.

2.3. Key vitamins and minerals for immunity:

Vitamin C (ascorbic acid): A powerful antioxidant protects cells from damage, stimulates the production of leukocytes and increases their effectiveness. Promotes wound healing and strengthens the barrier functions of the skin and mucous membranes. Vitamin C deficiency can weaken the immune system and increase the risk of infections. The recommended daily dose is 75 mg for women and 90 mg for men.
Vitamin D (calciferol): Plays an important role in the regulation of the immune system. Activates T cells and B cells, participates in the production of antimicrobial peptides and modulates the inflammatory response. Vitamin D deficiency is associated with an increased risk of infections, autoimmune diseases and cancer. Vitamin D is synthesized in the skin under the influence of sunlight, but it can also be obtained from food and dietary supplements. The recommended daily dose is 600 IU (international units) for adults.
Zinc: It is necessary for the normal functioning of immune cells, including T cells, B cells and NK cells. Participates in the production of cytokines and antibodies, promotes healing of wounds and protects cells from oxidative stress. Zinc deficiency can weaken the immune system and increase the risk of infections. The recommended daily dose is 8 mg for women and 11 mg for men.
Selenium: The antioxidant protects cells from damage and participates in the regulation of the immune system. It is necessary for the normal functioning of the thymus and the production of antibodies. Selena deficiency can weaken the immune system and increase the risk of infections. The recommended daily dose is 55 μg.
Vitamin E (Tokoferol): A powerful antioxidant protects cells from damage, stimulates the production of antibodies and improves the function of immune cells. Vitamin E deficiency can weaken the immune system and increase the risk of infections. The recommended daily dose is 15 mg.
Vitamin A (Retinol): He plays an important role in maintaining the integrity of the mucous membranes, which are an important barrier against infections. Participates in the regulation of the immune system and the production of antibodies. Vitamin A deficiency can weaken the immune system and increase the risk of infections. The recommended daily dose is 700 mcg for women and 900 mcg for men.
Iron: It is necessary for the normal functioning of immune cells and the production of hemoglobin, which tolerates oxygen to cells. Iron deficiency can weaken the immune system and increase the risk of infections. The recommended daily dose is 18 mg for women and 8 mg for men.

2.4. Other dietary supplements to strengthen immunity:

Probiotics: Living microorganisms that benefit health, improving the balance of intestinal microflora. A healthy intestine plays an important role in the immune system, since most of the immune cells are in the intestines. Probiotics can stimulate the immune response, reduce inflammation and protect against infections. Examples of probiotics include Lactobacillus and Bifidobacterium.
Prebiotics: Interesting fibers that serve as food for beneficial bacteria in the intestines. Prebiotics contribute to the growth and activity of probiotics, thereby improving the intestinal health and the immune system. Examples of prebiotics include inulin and fruitoligosaccharides (phos).
SOUTINATEA: A plant that is traditionally used to treat colds and influenza. Echinacea can stimulate the immune response, increase the number of leukocytes and improve their function.
Black Black: Berries rich in antioxidants that can help protect the cells from damage. Busina Black can also have an antiviral effect and reduce the duration and severity of the cold and influenza.
Garlic: Contains allicin, compound with antibacterial, antiviral and antifungal properties. Garlic can stimulate the immune response and protect against infections.
Ginseng: A plant that can improve the function of the immune system and increase stress resistance. Ginseng contains ginzenosides, compounds with immunomodulating properties.
Turmeric: Contains curcumin, compound with antioxidant and anti -inflammatory properties. Kurkumin can modulate an immune response and protect against chronic diseases.
Beta-glucan: Polysaccharides found in the cell walls of mushrooms, yeast, bacteria and plants. Beta-glucans can stimulate the immune response, activating macrophages and other immune cells.
Coenzim Q10 (COQ10): The antioxidant necessary for the production of energy in cells. COQ10 can improve the function of the immune system and protect the cells from damage.
Amino acids: Some amino acids, such as glutamine and Arginine, play an important role in maintaining the immune function. Glutamin is the main source of energy for immune cells, and Arginine is involved in the production of nitrogen oxide, which has antimicrobial properties.

2.5. How to choose dietary supplements for immunity:

Consult a doctor or other qualified specialist in the field of healthcare: Before taking any dietary supplements, especially if you have any diseases or you take any medicine, it is important to consult a doctor.
