Probiotics in recent systematic reviews and meta-analyses were shown to be superior to placebo regarding several anthropometric and laboratory metabolic parameters, including serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in both adult and paediatric patients [93,95,112], as well as inflammation markers [112,113] in NAFLD patients. This evidence concerns the gene GPT and metabolic dysfunction-associated steatotic liver disease.
