Metabolic Cofactor Supplementation in Obese Patients With Non-Alcoholic Fatty Liver Disease

Subjects in active treatment will receive dietary supplementation with N-acetylcysteine, L-carnitine tartrate, nicotinamide riboside, and serine, administered as a mixture. Half dosage of the co-factors will be given for two weeks (one dose taken just after dinner), and full dosage for 8 weeks (two equal doses taken just after breakfast and dinner).

As placebo, sorbitol (5 g) flavored with strawberry aroma and coloring agent will be given. Sorbitol is widely used due to its solubility in water. It's approved by the U.S. Food and Drug Administration (FDA).
