GPT and metabolic dysfunction-associated steatotic liver disease: In this study, we used zebrafish for NAFLD research, and the results indicated the nutraceutical complex containing choline bitartrate, zinc, and vitamin E exhibits a pronounced hepatoprotective effect against NAFLD, resulting in reduced levels of alanine transaminase and aspartate aminotransferase activity, as well as enhanced hepatic fat transfer when compared with choline bitartrate alone intervention group.
