Using niacin to shift fat into body fat and away from the liver
Official title: Stimulating Adipose Tissue Fatty Acid Disposal With Low-dose, Postprandial, Intermittent Niacin for the Treatment of Metabolic Dysfunction-associated Steatotic Liver Disease (MASLD).
Run by Université de Sherbrooke · NCT06843148 · Data updated 2026-11-12
This study will test whether daily niacin can lower liver fat and increase storage of dietary fat in body fat in people age 50–80 with MASLD and abdominal obesity.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are men and postmenopausal women aged 50–80 with MASLD and abdominal obesity but without advanced fibrosis or prior diabetes.
✕Probably not a fit
People with advanced liver fibrosis, other chronic liver diseases, diagnosed diabetes, major cardiovascular or renal disease, contraindications to MRI, prior niacin intolerance, or recent research radiation exposure are unlikely to benefit or be eligible.

What this trial studies
This is a randomized crossover study in which participants receive 12 weeks of oral niacin and 12 weeks of placebo in random order with a 4-week washout between phases. Dosing escalates over three weeks to 750 mg daily, taken at the end of the largest meal, and outcomes are measured at the end of each treatment phase. Metabolic testing includes two intensive 9-hour visits per phase with a test meal, stable isotope tracers, PET with 18FTHA and 11C-palmitate, MRI, and blood sampling to measure hepatic and adipose fatty acid flux. The design includes paired visits without and with acute niacin given with the test meal to measure immediate effects on fatty acid trafficking.
Why it matters
Potential benefit: If successful, niacin could reduce liver fat by redirecting dietary fatty acids into subcutaneous adipose tissue, potentially lowering risk of liver inflammation and progression.
How similar studies have gone: Prior studies have shown niacin acutely suppresses lipolysis and lowers circulating free fatty acids, but using chronic niacin to redirect dietary fat into adipose and reduce liver fat is a relatively novel, unproven approach.
