I. Introduction to the immune system and the role of dietary supplements in its support

The immune system is a complex complex of cells, tissues and organs designed to protect the body from pathogens, viruses, parasites and other foreign agents. The effectiveness of the immune system depends on many factors, including genetics, age, general health, diet and lifestyle. During the cold, when the risk of infection with viral infections increases, maintaining a strong immune system becomes especially important.

Dietary supplements, or dietary supplements, can play an auxiliary role in strengthening immunity, providing the body with the necessary nutrients that may be absent or contained in insufficient quantities in the usual diet. It is important to understand that dietary supplements are not a replacement for a balanced diet and a healthy lifestyle, but serve as an addition to them. They can help compensate for the deficiency of certain vitamins, minerals and other biologically active substances necessary for the optimal operation of the immune system.

II. Vitamins and minerals to strengthen immunity

Some vitamins and minerals play a key role in maintaining the normal function of the immune system. Their deficiency can weaken immune defense and increase susceptibility to infections.

Vitamin A deficiency can weaken the immune function and increase susceptibility to infections. The recommended daily dose of vitamin A for adults is 700-900 μg. Sources of vitamin A: liver, dairy products, eggs, carrots, sweet potatoes, spinach. Addresses with vitamin A are available in the form of capsules and tablets. It is important to observe the recommended dosage of vitamin A, since its excess can be toxic.
