Why do these people need a supplementation of NK cells

In the intricate and complex castle of the human body, immune cells are undoubtedly the loyal guardians of health. They are like the elite forces within the castle, constantly patrolling, resisting external invasions, and eliminating internal insurgents. And NK cells (Natural Killer cells) are the elite of this force, with their unique rapid response capability, able to identify and eliminate abnormal cells without prior instructions, including latent cancer cells, virus-infected cells, and harmful pathogens.
NK cells, as the 'rapid response force' of the human immune system, are of paramount importance. They can quickly recognize and attack cells marked as abnormal or dangerous, thereby maintaining the body's internal stability. However, with age, the accumulation of unhealthy lifestyle habits, prolonged exposure to adverse environments, and the impact of immune system diseases, the activity and number of NK cells may gradually decline, weakening the immune system's defense capabilities and increasing the risk of disease.
Studies have confirmed that age is one of the important factors affecting NK cell activity. As age increases, the body's cellular immune function gradually declines, and the number and function of NK cells are no exception. Especially after the age of 40, the number and activity of NK cells begin to decline significantly. By the age of 60, their function may be only half of that of young people. This means that middle-aged and elderly people are more susceptible to infections and cancer. Therefore, regular monitoring and timely supplementation of NK cells are crucial for maintaining the health of middle-aged and elderly populations.

• High-risk cancer individuals: Middle-aged and elderly people, those with a family history of tumors, and those with long-term exposure to chemical pollutants, radiation, or unhealthy habits. Due to declining immune system function and increased risk of gene mutations, NK cell supplementation is needed to reduce the risk of cancer.
• Individuals with low immunity and recurrent infections: Whether caused by congenital immune deficiencies or acquired factors leading to decreased immune system function, NK cell supplementation can enhance resistance and accelerate recovery.
• Individuals troubled by chronic inflammation: Chronic inflammatory environments can damage tissues and organs and interfere with the immune system. The introduction of NK cells can regulate the secretion of inflammatory factors and reduce inflammatory responses.
• Sub-healthy office workers: High-intensity work rhythms and mental stress can hinder the activity of NK cells in office workers. NK cell supplementation helps restore activity and enhance overall immunity.
• Post-operative rehabilitation patients: Timely supplementation of NK cells can accelerate the clearance of residual cancer cells, prevent tumor recurrence, and help resist external pathogens.
• Cancer patients undergoing radiotherapy and chemotherapy: Radiotherapy and chemotherapy can damage normal cells and reduce NK cell activity. NK cell supplementation helps restore immune system function, reduce side effects, and improve quality of life.
• Patients with chronic diseases: Such as those with diabetes and cardiovascular disease, who experience a decrease in NK cell count and activity. NK cell supplementation helps improve physical function.
• Individuals at high risk of viral infections: NK cells play a crucial role in antiviral immunity, helping to enhance antiviral capabilities."
