Does curcumin improve liver enzymes levels in nonalcoholic fatty liver disease? A systematic review, meta-analysis, and meta-regression
Phytotherapy research : PTR (2024) · Meta analysis · n=835
Subgroup analysis revealed that adding piperine to curcumin did not benefit aminotransferase levels in NAFLD patients.
Curcumin supplementation effect on liver enzymes in patients with nonalcoholic fatty liver disease: a GRADE-assessed systematic review and dose-response meta-analysis of randomized controlled trials
Nutrition reviews (2025) · Meta analysis · n=905
Curcumin supplementation significantly reduced ALT (weighted mean difference [WMD], -4.10, 95%CI, -7.16 to -1.04) and AST (WMD, -3.27; 95%CI, -5.16 to -1.39), but not ALP (WMD, -0.49; 95%CI, -1.79 to 0.82).

Comparative efficacy and tolerability of nutraceuticals for depressive disorder: A systematic review and network meta-analysis
Psychological medicine (2025) · Meta analysis · n=17437
Network meta-analysis of 192 trials in 17,437 adults with depressive disorder, covering 44 nutraceuticals.
Three small human pharmacokinetic trials in which piperine was the only thing added. At 5 mg a day, piperine with 120 mg coenzyme Q10 for 21 days gave about a 30% larger plasma AUC than CoQ10 with placebo in healthy men (PMID 10715596, double-blind, sample size not stated), while the single-dose and 14-day results were smaller and not significant. At 20 mg, a single dose with 2 g curcumin raised curcumin bioavailability by 2000% in healthy volunteers, with no adverse effects (PMID 9619120). At 20 mg a day for 10 days, piperine raised carbamazepine AUC by 47.9% in 12 healthy volunteers (PMID 27776366, open-label). Each trial used a different partner compound and none compared piperine doses, so no optimal dose is set. The same effect raises drug levels, which is why the drug interactions matter.
