Top dietary supplements for immunity: comparison of prices and quality

Part 1: the foundation of the immune system and the role of dietary supplements

The immune system is a complex complex of organs, tissues, cells and molecules designed to protect the body from pathogens, such as bacteria, viruses, fungi and parasites. Her uninterrupted work is critical to maintain health and prevent diseases. The immune system performs many functions, including recognition of foreign agents, the destruction of infected cells, the production of antibodies and the formation of immune memory for rapid response to repeated invasions.

Factors weakening the immune system include: improper nutrition, lack of sleep, stress, chronic diseases, environmental pollution, alcohol abuse and smoking. The consequences of weakened immunity are frequent colds, exposure to infections, protracted recovery and increased risk of chronic diseases.

Biologically active additives (dietary supplements) are positioned as means for maintaining and strengthening the immune system. They contain concentrated doses of vitamins, minerals, plant extracts and other biologically active substances. It is important to understand that dietary supplements are not medicines and are not intended for the treatment of diseases. Their task is to support the body in conditions when it experiences a deficiency of certain nutrients or undergoes increased load.

The choice of dietary supplements for immunity requires a thorough approach. Not all additives are equally effective and safe. The key criteria for choosing are the composition, dosage, form of release, manufacturer, availability of quality certificates and consumer reviews. Before taking dietary supplements, it is recommended to consult a doctor, especially in the presence of chronic diseases or taking other drugs.

The disadvantage of vitamin C can lead to a weakening of immunity, increased susceptibility to infections and slow healing of wounds. The recommended daily dose of vitamin C for adults is 75-90 mg.
