The immune response is the body's defense mechanism against pathogens, including bacteria, viruses, and fungi. It involves a complex network of cells, tissues, and organs that work together to identify and eliminate harmful invaders while maintaining the body’s overall health.

Signs and Advantages: A well-functioning immune response is characterized by the body’s ability to fight off infections and heal from injuries. Symptoms of a strong immune response include quick recovery from illness and minimal occurrences of infections.

Probiotics and Immune Response: Probiotics are beneficial bacteria that can enhance the immune response by promoting a balanced gut microbiome. They help stimulate the production of antibodies and activate immune cells, which can lead to a reduced risk of infections and improved overall immune function.
