Glycine supplementation for MASLD health

Official title: Investigating the Effects of Dietary Glycine Supplementation in Patients With Metabolic Dysfunction-associated Steatotic Liver Disease

Run by Singapore General Hospital · NCT07285135 · Data updated 2026-11-12

This study tests whether adding glycine to the diet helps people with MASLD improve liver fat and metabolic balance.

Is this trial a fit for you?

Likely a good fit

Adults 21-70 with MASLD (BMI 25-50) or healthy controls (for the cross-sectional component); MASLD participants must have hepatic steatosis on MRI and meet inclusion criteria.

Probably not a fit

MASLD patients who do not respond to glycine supplementation or have contraindications may not experience liver fat reduction.

What this trial studies

This project has two parts: a cross-sectional comparison of glycine-related metabolism between MASLD patients and healthy controls, and a 26-week, randomized, double-blind, placebo-controlled trial of glycine (9 g/day) versus placebo in MASLD patients. The primary goals are to see if urinary acylglycine levels differ between groups and whether liver fat content measured by MRI-PDFF changes with glycine supplementation. Secondary assessments include broader metabolic profiles and safety monitoring. The study is conducted at Singapore General Hospital with MASLD participants aged 21-70 and BMI 25-50, alongside non-MASLD controls.

Why it matters

Potential benefit: If successful, glycine supplementation could become a simple dietary approach to improve liver fat and metabolic health in MASLD.

How similar studies have gone: Prior work has explored amino-acid–based approaches in liver disease, but this specific glycine supplementation strategy in MASLD is being tested for the first time in this design.
