Vitamin-Pills
In biology, immunity is the balanced state of multicellular organisms having adequate biological defenses to fight infection, disease, or other unwanted biological invasion, while having adequate tolerance to avoid allergy, and autoimmune diseases. Supplementation is the use of pills or special types of food in order to improve your health.
A bidirectional relationship among nutrition, infection and immunity exists: changes in one component affect the others. Distinct immune features present during each life stage may affect the type, prevalence, and severity of infections, while poor nutrition can compromise immune function and increase infection risk.
