A recent randomized controlled clinical trial has shown that the administration of Indena’s bioavailable curcumin formulation, Meriva®, may improve the health status in subjects with non-alcoholic fatty liver disease (NAFLD), as assessed by multiple liver parameters.
This is the first clinical study investigating the effects, efficacy and safety of curcumin phytosome supplementation in fatty liver disorders.
The study aimed to assess the effects on metabolic profile in subjects with NAFLD[1, 2].
Eighty seven subjects diagnosed with grades 1-3 (according to liver sonography) were enrolled and randomly assigned to curcumin (1000 mg per day in 2 divided doses) (n = 44) or control (n = 43) group for a period of 8 weeks.
Supplementation with Meriva® was associated with reductions in BMI (P = 0.003) and waist circumference (P < 0.024). Consistent with the findings of liver ultrasonography, serum levels of AST and ALT were reduced by the end of trial in the curcumin group (respectively from 35.46±22.97 to 24.85±12.84 and from 27.63±11.35 to 20.68±6.65, P < 0.001) but elevated in the placebo group (respectively from 36.81±24.32 to 41.33±23.97 and from 27.44±10.01 to 31.23±12.80, P < 0.001).
The effect of curcumin in reducing serum AST (P < 0.001) and ALT (P < 0.001) levels was also significant in the between-group comparison. Likewise, ultrasonographic findings improved in 75% of subjects in the curcumin group while the rate of improvement in the control group was 4.7% (P < 0.001).
Furthermore, supplementation with Meriva® was associated with a reduction of serum levels of total cholesterol (P < 0.001), LDL cholesterol (P < 0.001), triglycerides (P < 0.001), non-high density lipoprotein cholesterol (P < 0.001), and uric acid (P < 0.001).
No safety and tolerability issues were reported during the 8 weeks of treatment.
“Non-Alcoholic fatty liver disease is the most common chronic liver disorder in the Western Countries, affecting 30% of the general adult population, up to 60-70% in diabetic and obese patients” – commented Antonella Riva, Product Research Manager at Indena. “This is the first clinical study investigating the effects of Meriva® in improving liver health; the positive results we obtained show that our bioavailable curcumin formulation may help to improve the health status in these subjects. Our commitment in Research and Development drives us to explore important goals to fulfil the unmet and increasing health needs deriving from modern life style conditions”.
These new data supporting the consistency and strength of Meriva® in fatty liver will be presented at the coming 11th World Congress on Polyphenols Applications (Vienna, June 20-21, 2017).

Meriva® is a patented delivery form of curcumin based on Indena’s proprietary Phytosome® technology, for healthy inflammatory response, joint health and eye health. Pharmacokinetic comparison studies have shown Meriva® to improve the overall curcuminoids bioavailability by about 30-fold, and significant absorption benefits; in particular, demethoxycurcumin (the most potent curcuminoid in numerous bioassays) was found to be 50-fold more bioavailable as compared to a non-formulated curcumin extract. Indena technology relies on the use of dietary adjuvants (lecithin) and is supported by 29 clinical trials on efficacy and by a robust tolerability and safety profile.
