Are probiotics given to replace the natural flora of the intestine?

Probiotics are not meant to entirely replace the natural flora of the intestine but rather to support and enhance the existing microbiota. They can help restore balance, especially after disturbances like antibiotic use or gastrointestinal infections. By introducing beneficial bacteria, probiotics may promote a healthier gut environment and improve overall digestive health. However, they work best in conjunction with a diverse and healthy diet that nourishes the natural flora.
