Immunity refers to the body’s natural mechanisms for responding to environmental factors and external influences. Its proper functioning is closely connected to overall lifestyle, physical activity, mental well-being, and balanced nutrition.

In the context of immune support, vitamins, minerals, and other nutrients traditionally associated with these processes are often discussed. Commonly included ingredients are B-complex vitamins, vitamin C, vitamin D, zinc, selenium, iron, and magnesium — substances that form the foundation of many dietary supplements focused on immune support.
