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).
Curcumin plus piperine supplementation had no significant effect on ALT (WMD, -3.79; 95%CI, -13.30 to 5.72), and AST (WMD, -1.1; 95%CI, -3.32 to 1.09).
Curcumin supplementation improved AST and ALT levels compared with the control group.
Consequently, longer trials utilizing high doses of curcumin could diminish the positive impact of curcumin in reducing serum levels of aminotransferases in patients with NAFLD.
Aragón-Vela J et al. · Phytotherapy research : PTR (2024)
Subgroup analysis revealed that adding piperine to curcumin did not benefit aminotransferase levels in NAFLD patients.
Additionally, we found a negative correlation between the duration of the intervention and the relative (mg/kg/day) curcumin dose with the reduction in liver aminotransferases.
In summary, the sources of heterogeneity identified in our study are likely attributed to the duration of the intervention and the relative dose of curcumin.

The standardized mean difference (SMD) with a 95% confidence interval (CI) was used to present the results.
There was a significant reduction in circulating MDA concentrations (SMD = -0.769, 95% CI: -1.059 to -0.478) and a significant increase in SOD activity (SMD = 1.084, 95% CI: 0.487 to 1.680) following curcumin supplementation.
This effect was greater when combined with piperine than curcuminoids alone (SMD = -1.085, 95% CI: -1.357 to -0.813; SMD = -0.850, 95% CI: -1.158 to -0.542).
However, further long-term RCTs are required to ascertain their clinical benefit.
Hosseini H et al. · Phytotherapy research : PTR (2023)
The combined results by the random-effects model demonstrated that curcumin plus piperine significantly decreased total cholesterol and LDL-C in patients suffering from metabolic syndrome.
In comparison, the results of the overall effect size did not show any significant change in triglyceride concentrations.
Our results were robust in sensitivity analysis and were not dependent on the dose of curcumin, the dose of piperine, and the duration of treatment.

Supplementation with curcuminoid-piperine combination significantly improved serum SOD activities (p < 0.001) and reduced MDA (p < 0.001) and CRP (p < 0.001) concentrations compared with placebo.
Quantitative data synthesis revealed a significant effect of curcuminoids vs. placebo in reducing circulating CRP concentrations (weighed mean difference: -2.20 mg/L; 95% confidence interval [CI]: -3.96, -0.44; p = 0.01).
Curcuminoids could be regarded as natural, safe and effective CRP-lowering agents.

According to the current meta-analysis, curcumin plus piperine administration showed a significantly increased SOD activity and GSH levels while significantly decreased MDA concentrations.
In addition, our study revealed that curcumin plus piperine significantly decreased TNF-α and IL-6 concentrations.

As a conclusive remark, P. nigrum should not only be regarded as "King of spices" but can also be considered as part of the kingdom of medicinal agents, comprising a panoply of bioactive compounds with potential nutraceutical and pharmaceutical applications.
Takooree H et al. · Critical reviews in food science and nutrition (2019)
The major bioactive compound identified in P. nigrum is piperine although other compounds are also present including piperic acid, piperlonguminine, pellitorine, piperolein B, piperamide, piperettine, and (-)-kusunokinin, which also showed biological potency.
Most pharmacological studies were conducted in vitro (n = 60) while only 21 in vivo and 1 clinical trial were performed.
Hence, more in vivo experiments using a pharmacokinetic and pharmacokinetic approach would be beneficial.

To estimate the pooled effect size, weighted mean differences (WMDs) with corresponding 95% confidence intervals (CIs) were calculated, applying a random-effects model to account for potential variability between studies.
However, the reduction in low-density lipoprotein cholesterol (LDL-C) was not statistically significant (WMD: -2.20 mg/mL, 95% CI: -7.22, 2.80, p = 0.387).
Curc + Pipe has clinically meaningful lipid-modulating effects, particularly in reducing TG and TC and modestly increasing HDL-C levels.

Its dual redox behavior-antioxidant at low doses and pro-oxidant at higher doses-confers context-dependent selectivity, enabling oxidative stress-mediated apoptosis in tumor cells.
Compared with other nutriepigenetic agents (curcumin, resveratrol, EGCG), piperine stands out for its multi-target profile and preliminary evidence of activity against cancer stem cell-like phenotypes.
Nonetheless, limited solubility, rapid metabolism, and scarce in vivo validation constrain clinical translation.

The present study was carried out with a total of 120 women with locally advanced/metastatic breast cancer, who were randomized to receive standard chemotherapy alone or chemotherapy with oral curcumin, a 500 mg capsule (1 g/day) containing 95% curcuminoid and 1% piperine given for 12 to 24 weeks.
ORR was significantly higher in the curcumin group than in those who received standard chemotherapy (38.33% vs. 8.33%, p < 0.01) at 4 weeks follow-up post-treatment, which further improved (43.40% vs. 10.64%, p < 0.0031) upon completion of 12 weeks post-treatment.
Curcumin-treated women displayed higher physical performance, better prognosis and QoL, better tolerance to chemotherapy, fewer adverse effects, and better PFS.

Upon investigating the dual nature of Nrf2, it became clear that, in addition to shielding normal cells from numerous stresses, Nrf2 may also promote the growth of tumors.
Among these, 12 Generally Recognized As Safe (GRAS) certified nutraceuticals, sulforaphane is the most extensively studied compound in modulating Keap1-Nrf signaling.
