White blood cells play a vital role in your immune system by defending the body against infections and foreign invaders. These cells identify, target, and destroy harmful bacteria, viruses, and other pathogens. When an infection occurs, white blood cells quickly increase in number to fight it off. For example, cephalexin capsules wholesale suppliers offer antibiotics commonly used to treat bacterial infections, supporting white blood cell function by reducing the bacterial load. Together, antibiotics and a strong immune response help speed up recovery. Maintaining a healthy immune system ensures white blood cells can function effectively to protect your body.
