Hepatoprotective effect of combination of L-carnitine and magnesium-hydroxide in nonalcoholic fatty liver disease patients: a double-blinded randomized controlled pilot study.

OBJECTIVE

Non-alcoholic fatty liver disease (NAFLD) still has no accepted pharmacological therapy. Even though monotherapy of L-carnitine or magnesium supplementation exhibits an essential beneficial role in NAFLD treatment, and despite that new NAFLD treatment strategies focus on combination therapies, the combination of L-carnitine with magnesium has not yet been examined in NAFLD patients. We aimed to assess the efficacy of L-carnitine in combination with magnesium in NAFLD patients.

PATIENTS AND METHODS

Double-blinded, randomized controlled trial with 22 NAFLD participants who were randomized to either control group receiving placebo for the first 8 weeks and an additional 8 weeks with CIRRHOS product (2 gr L-carnitine and 150 mg magnesium) or treatment group receiving CIRRHOS product for 16 weeks. Weight, serum aspartate aminotransferase (AST), alanine transaminase (ALT) and C-reactive protein (CRP) levels were measured monthly. Lipid profile and serum insulin levels were monitored at baseline and at week 16 of treatment. Shear-wave elastography was used to evaluate liver stiffness (LS).

RESULTS

While AST and ALT levels decreased progressively over 16 weeks of treatment in the treatment group, AST and ALT levels of the control group were increased modestly or unaffected. AST and ALT levels of the treatment group decreased by 25% (p=0.9) and 20% (p=0.1) respectively, compared to AST and ALT levels at baseline. However, serum CRP levels, insulin levels, lipid profile and LS were not affected by treatment.

CONCLUSIONS

Our findings suggest that L-carnitine with magnesium supplementation could be a potential therapy for NAFLD. However, further studies with a larger population and high-sensitivity diagnostic parameters for early stages of NAFLD are needed to elucidate L-carnitine and magnesium efficacy in NAFLD.
