Dietary supplement with zinc to strengthen immune defense

Dietary supplements with zinc to strengthen immune protection: guide to choose, use and efficiency

Section 1: Zinc – the basis of immunity and health

1. The role of zinc in the human body. Zinc is an indispensable trace element involved in numerous biochemical processes that support human health. It plays a key role in growth and development, functioning of the immune system, wound healing, DNA synthesis and proteins, as well as maintaining a sense of taste and smell. The lack of zinc can lead to various health problems, including weakening of immunity, growth retardation, skin rashes and a decrease in cognitive functions.

2. Zinc and immune system: mechanisms of interaction. Zinc has a multifaceted effect on the immune system, affecting various components of both congenital and acquired immunity. It is necessary for the development and functioning of immune cells, such as lymphocytes, macrophages and neutrophils. Zinc is involved in the synthesis and release of cytokines – signal molecules that regulate immune reactions. It is also important for the normal function of the thymus-the body responsible for the maturation of T-lymphocytes. Zinc deficiency leads to a violation of the work of these cells, a decrease in their ability to fight infections and an increase in susceptibility to diseases.

3. Signs and symptoms of zinc deficiency. Zinc deficiency can be manifested by various symptoms that vary in severity depending on the level of deficiency and individual characteristics of the body. The most common features include:

   • Reducing immunity and frequent infectious diseases (colds, flu, herpes).
   • Delayed growth and development in children.
   • Skin rashes, dermatitis, eczema.
   • Hair loss.
   • Diarrhea.
   • Loss of appetite.
   • Reducing a sense of taste and smell.
   • Slow wound healing.
   • Fatigue and weakness.
   • Reducing cognitive functions, worsening memory and concentration of attention.

4. Factors contributing to zinc deficiency. Various factors can contribute to the development of zinc deficiency, including:

   • Insufficient consumption of zinc with food (for example, with a vegetarian or vegan diet).
   • Violation of zinc absorption in the intestines (for example, with diseases of the gastrointestinal tract).
   • An increased need for zinc (for example, during pregnancy, lactation, active sports).
   • Chronic diseases (for example, diabetes mellitus, kidney disease, liver).
   • Taking certain drugs (for example, diuretics, proton pump inhibitors).
   • Alcoholism.
   • Aging (reduction of zinc absorption with age).

5. Sources of zinc in food. Zinc is contained in various foods, both animal and plant origin. The best sources of zinc include:

   • Oysters (very rich in zinc).
   • Beef.
   • Mutton.
   • Bird (especially dark meat).
   • Seafood (crabs, shrimp, lobsters).
   • Pumpkin seeds.
   • Snems of sesame seeds.
   • Nuts (cashews, almonds).
   • Legumes (beans, lentils).
   • Whole grain products (oatmeal, brown rice).
   • Dairy products (milk, cheese, yogurt).

   It is important to note that the bioavailability of zinc from plant sources can be lower than from animals, due to the content of phytats that bind zinc and preventing it from absorption. Soaking of legumes and whole grains before cooking can help reduce the content of phitat and increase the bioavailability of zinc.

Section 2: Bades with zinc: classification and forms
