To naturally boost your white blood cell count, focus on a nutrient-rich diet including vitamin C, zinc, and antioxidants found in citrus fruits, leafy greens, and berries. Adequate sleep, regular exercise, and stress management also support immune health. Herbal supplements like echinacea and astragalus may help, but consult your doctor first. Avoid smoking and limit alcohol intake. Staying hydrated and practicing good hygiene prevents infections that can lower white blood cell levels. If you’re recovering from an infection and have used ceftriaxone injection, talk to your healthcare provider about ways to naturally restore your immune balance and maintain overall wellness.
