The overall estimates and their 95% confidence intervals (CIs) were calculated using a random-effects model.
The results showed that Garcinia cambogia has no significant effect on FBS (weighted mean difference (WMD): 1.02 mg/dl, 95% CI: -1.29, 3.33), insulin (WMD: -0.12 mU/L, 95% CI: -1.50, 1.25), AST (Hedges' g: -0.08, 95% CI: -0.43, 0.26), and ALT (Hedges' g: 0.27, 95% CI: -0.20, 0.73).
Subgroup analysis showed that Garcinia cambogia significantly increased insulin levels in females and also increased insulin and FBS levels in those with a BMI ≥30 kg/m 2 .
Einfach gesagt: Achieving this goal requires collaborative efforts from both consumers and clinicians.

The discussion extends to notable examples of both currently popular and potential future dietary supplements, such as garcinia cambogia, turmeric, and ashwagandha, accompanied by an overview of recent findings.
Causality assessment tools play a crucial role in establishing a connection between these products and instances of liver injury, with consideration of the advantages and disadvantages associated with their use.
Fostering a comprehensive understanding of regulatory standards, coupled with a solid foundation of knowledge of DS, will prove instrumental in preventing DS-related hepatotoxicity.
Einfach gesagt: Proposed mechanisms of toxicity include genetic predisposition to immune-mediated reactions involving the human leucocyte antigen HLA-B*35:01 allele, induction of hepatocyte oxidative stress and inflammation, and hepatocyte apoptosis caused by the active constituent, hydroxycitric acid, which inhibits mitochondria ATP-citrate lyase.
van Breemen RB, Roe AL, Akhtar N. · Pharmaceutical biology (2025)
A total of 34 case reports of Garcinia hepatotoxicity indicated one death and nine liver transplants, with 17 cases receiving CIOMS/RUCAM scores that indicated possible to highly probable causality due to Garcinia dietary supplements.
In one case, causality was confirmed by rechallenge with Garcinia .
Discussion and conclusions Garcinia toxicity was consistent with drug-induced liver injury and included elevated serum liver enzymes alanine aminotransferase (ALT) and aspartate aminotransferase with a high ratio of ALT to alkaline phosphatase.

Using random effects, weighted mean differences (WMDs) and corresponding 95 % confidence intervals (CIs) were computed.
Our analysis, with no indication of publication bias, showed a significantly decreased effect of GC on leptin compared with the placebo (WMD: -5.01 ng/ml; 95 % CI: -9.22 to -0.80, p = 0.02).
However, significant heterogeneity was detected between studies (I 2 =93.5 %, p < 0.001).
Einfach gesagt: This information is expected to be useful for healthcare professionals to detect and intervene on food supplement-drug interactions to ensure the optimization of therapy and patient safety.
Rivas García F, García Sierra JA, Valverde-Merino MI, Zarzuelo Romero MJ. · Pharmaceuticals (Basel, Switzerland) (2024)
As excess weight is a long-term condition, some supplements are expected to be used for long periods of time.
The long-term use of these dietary supplements makes it highly likely that they will be combined with medications, increasing the risk of food supplement-drug interactions, which are not always known or disclosed, and can lead to serious health problems, as has been observed.
This information is expected to be useful for healthcare professionals to detect and intervene on food supplement-drug interactions to ensure the optimization of therapy and patient safety.

This review moves beyond a mere compilation of GA's effects to provide a systematic and critical analysis of its pharmacological landscape.
By directly comparing GA with other natural products (e.g., flavonoids) in terms of structure-activity relationships and translational potential, we highlight its unique position in the natural product pharmacopeia.
We conclude that the future of GA research lies in the integration of multi-omics approaches with precision drug delivery systems, a synergistic strategy that will effectively bridge the gap between its robust mechanistic underpinnings and successful clinical application.
Einfach gesagt: Fortunately, with the formation of major DILI consortiums across the world, the last decade has seen advances in the identification of at-risk genetic phenotypes, the use of chemical analysis on multi-ingredient nutritional supplements, and the publication of data/injury patterns of potentially risky HDS.
Halegoua-DeMarzio D, Navarro V. · Liver international : official journal of the International Association for the Study of the Liver (2025)
Mirroring this trend, HDS-induced liver injury, also known as HDS-induced liver injury (HILI), has increased significantly over the past three decades in the Drug-Induced Liver Injury Network (DILIN), now accounting for 20% of cases of drug-induced liver injury (DILI).
The major implicated agents include anabolic steroids, green tea extract, garcinia cambogia, kratom, ashwagandha, turmeric and multi-ingredient nutritional supplements.
Einfach gesagt: This review underscores the importance of continued investigation into phytochemicals as a complementary approach to addressing the global obesity epidemic, potentially leading to more effective and natural interventions for weight management.
Rao PP. · Current nutrition reports (2025)
However, research in this field also faces challenges, including inconsistent bioavailability and the need for standardized dosing protocols.
Phytochemicals offer a promising avenue for obesity management, acting through multiple pathways to influence weight control.
While clinical evidence supports the efficacy of certain phytochemicals, further research and rigorous clinical validation are necessary to fully understand their potential and overcome existing challenges.
Einfach gesagt: This review also aims to provide adequate knowledge regarding herbalism in traditional practices, pertinent for medical doctors to diagnose, treat, and prevent avoidable liver disease burdens within communities, and improve public health and education.
