Amino acid supplement may help fatty liver – new study
NCT ID NCT07285135
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether taking glycine, a natural amino acid, as a daily supplement for 26 weeks can improve liver health in people with metabolic fatty liver disease. Researchers will compare liver fat and blood markers between those taking glycine and those taking a placebo. The study involves 60 adults aged 21-70 with fatty liver or healthy controls.
