Specific probiotic and synbiotic interventions improve liver function markers (ALT, AST) and reduce liver fat in patients with Non-Alcoholic Fatty Liver Disease (NAFLD) and NASH.

If you have NAFLD or NASH, specific probiotics (like L. bulgaris/S. thermophilus or synbiotics with L. plantarum) taken daily for 8-30 weeks may help improve liver enzyme levels and reduce liver fat. This is a supportive strategy alongside lifestyle changes.
