1HbA1c reductionMeta-Analysisn=1,337 · large study2025
In plain English: However, further validation of these findings is necessary through extensive clinical studies with larger sample sizes.

Borderline
For HbA1c, silymarin was more effective than resveratrol (MD -2.08, 95%Cl -3.50 to -0.72) (P < 0.05).
For body mass index (BMI), curcumin was more effective than resveratrol (MD -1.27, 95%Cl -2.43 to -0.03) (P < 0.05).
Curcumin, resveratrol, silymarin, and berberine can effectively improve cardio-metabolic risk factors in T2DM, and different herbal phytochemicals have different clinical advantages.
3Total cholesterol reductionMeta-Analysisn=4,838 · very large study2024
In plain English: Berberine, alone or with other nutraceuticals, can provide a modest positive impact on lipid concentrations.
Hernandez AV et al. · Journal of dietary supplements (2024)

Products with berberine alone had less robust effects on TC (MD -12.08 mg/dL [95%CI: -21.79 to -2.37]), LDL (MD -9.26 mg/dL [95%CI: -20.31 to 1.78]), and HDL (MD 1.38 mg/dL [95%CI: -1.27 to 4.03]) but TG effects were similar (MD -17.40 mg/dL [95%CI: -32.57 to -2.23]).
Berberine, alone or with other nutraceuticals, can provide a modest positive impact on lipid concentrations.
4Inflammatory biomarkers reductionMeta-Analysisn=1,600 · large study2023
In plain English: However, more investigation and high-quality evidence must be conducted to obtain more comprehensive and generalizable results.
Vahedi-Mazdabadi Y et al. · Phytotherapy research : PTR (2023)
In addition, the non-linear analysis showed a significant lowering effect of berberine/barberry on IL-6 and TNF-α levels in doses <1000 mg/day and less than 5 weeks of intervention.
There are limitations to our findings, including low-quality studies and significant heterogeneity.
These interventions might be considered adjunct therapy to managing inflammation status.
5Glycemic control improvementMeta-Analysisn=5,000 · very large study2024
In plain English: The finding of our umbrella showed that the supplementation of BBR could be effective in improving glycemic parameters and inflammatory marker in adults.
6Clinical efficacy rate improvementMeta-Analysisn=952 · large study2024
In plain English: BBR demonstrates substantial efficacy in treating UC without causing severe adverse reactions and may serve as a viable complementary therapy.

BBR considerably improved the clinical efficacy rate (RR = 1.22, 95% CI [1.15, 1.30], P < 0.00001), attenuated the Baron score (SMD = -1.72, 95% CI [-2.30, -1.13], P < 0.00001) and reduced the DAI score (SMD = -2.93, 95% CI [-4.42, -1.43], P < 0.00001).
Additionally, it ameliorated clinical symptoms (SMD = -2.74, 95% CI [-3.45, 2.02], P < 0.00001), diminished inflammatory responses (SMD = -1.59, 95% CI [-2.14, 1.04], P < 0.00001), and modulated immune reactions (SMD = 1.06,95% CI [0.24,1.87], P <0.00001).
Nonetheless, the impact of BBR on reducing adverse reactions was not statistically significant (RR = 0.75, 95% CI [0.42, 1.33], P > 0.05).
7Liver enzymes improvementMeta-Analysisn=811 · large study2024
In plain English: This meta-analysis demonstrates berberine's efficacy in improving liver enzymes, lipid profile, and insulin sensitivity in NAFLD patients.
Nie Q et al. · Journal of translational medicine (2024)
This meta-analysis demonstrates berberine's efficacy in improving liver enzymes, lipid profile, and insulin sensitivity in NAFLD patients.
These results indicate that berberine shows promise as an adjunct therapy for NAFLD.
In plain English: Ours is the first study to report that for women with PCOS, myo-inositol combined with D-chiro-inositol and metformin combined with thiazolidinediones appear superior to metformin alone in improving insulin resistance and decreasing total testosterone.
Zhao H et al. · Reproductive health (2021)
Compared with metformin, treatment with myo-inositol + D-chiro-inositol was associated with a greater improvement in menstrual frequency (odds ratio 14.70 [95% confidence interval (CI) 2.31-93.58]).
Ours is the first study to report that for women with PCOS, myo-inositol combined with D-chiro-inositol and metformin combined with thiazolidinediones appear superior to metformin alone in improving insulin resistance and decreasing total testosterone.
Myo-inositol combined with D-chiro-inositol is particularly efficacious in menstrual recovery.
In plain English: Higher quality studies are needed to provide more high quality evidence.
Zhang LS et al. · The American journal of Chinese medicine (2019)
The results of meta-analysis showed that compared with the placebo group, berberine could significantly reduce the total cholesterol and low-density lipoprotein levels and elevate the high density lipoprotein level ( P<0.05 ).
Compared with the simvastatin group, berberine was effective only in reducing the level of triglyceride ( MD=-0.37 , 95% CI: - 0.66, - 0.07, P=0.02 ).
Compared with the simvastatin group, berberine plus simvastatin was more effective in reducing the level of triglyceride ( MD=-0.33 , 95% CI: - 0.46, - 0.20, P<0.00001 ) and total cholesterol ( MD=-0.36 , 95% CI: - 0.60, - 0.12, P=0.003 ).
In plain English: The dosage and treatment duration of Berberine and patients' age may modify the effect.
Liang Y et al. · Endocrine journal (2019)
We calculated weighted mean differences (WMD) and 95% confidence interval (CI) for fasting plasma glucose (FPG), postprandial plasma glucose (PPG) and glycated haemoglobin (HbA1c) levels.
The pool data showed that Berberine treatment was associated with a better reduction on FPG (WMD = -0.54 mmol/L, 95% CI: -0.77 to -0.30), PPG (WMD = -0.94 mmol/L, 95% CI: -1.27 to -0.61), and HbA1c (WMD = -0.54 mmol/L, 95% CI: -0.93 to -0.15) than control groups.
Subgroup-analyses indicated that effects of Berberine on blood glucose became unremarkable as the treatment lasted more than 90 days, the daily dosage more than 2 g/d and patients aged more than 60 years.
In plain English: We found a significant reduction in WHR following berberine consumption in adults.
Amini MR et al. · Complementary therapies in medicine (2020)
We found a significant reduction in WHR following berberine consumption in adults.
Further clinical trials with high quality according to challenges mentioned seem to be helpful to use berberine and barberry as a supplement for certain health conditions, efficiently.
