To increase white blood cell (WBC) production, focus on a nutrient-rich diet with vitamins B12, folate, and iron, found in leafy greens, eggs, and lean meats. Regular exercise, adequate sleep, and stress management support immune health. Avoid smoking and limit alcohol. Certain medications, like ceftriaxone injection wholesale, treat infections that may lower WBC counts, indirectly aiding production. Consult a doctor for persistent low WBC levels, as underlying conditions may require specific treatments like growth factors. Stay hydrated and avoid infections to maintain optimal immune function and WBC production.
