We conducted random-effects network meta-analysis with a Frequentist framework to estimate mean difference [MD] and 95% confidence interval [CI] of the effect of nutraceuticals on weight loss.
Supplementations with green tea (MD: -1.25 kg, 95%CI: -1.68, -0.82) and glucomannan (MD: -1.36 kg, 95%CI: -2.17, -0.54) demonstrated small weight loss, also the certainty of evidence was rated low.
Based on our findings, supplementations with nutraceuticals can result in a small weight loss in adults with overweight or obesity.

STW5 (Iberogast) may moderately improve global symptoms of dyspepsia compared with placebo at 28 to 56 days; however, the evidence is very uncertain (MD -2.64, 95% CI -4.39 to -0.90; I2 = 87%; 5 studies, 814 participants; very low CoE).
STW5 may also increase the improvement rate compared to placebo at four to eight weeks' follow-up (RR 1.55, 95% CI 0.98 to 2.47; 2 studies, 324 participants; low CoE).
There was little to no difference in adverse events for STW5 compared to placebo (RR 0.92, 95% CI 0.52 to 1.64; I2 = 0%; 4 studies, 786 participants; low CoE).

Subgroup analysis showed that, an intervention of more than 12 weeks was found to have a reducing effect on aspartate- aminotransferase (AST) measures (2 trials, n = 201 participants, WMD= -11.317; 95 % CI: -15.007, -7.626; P = 0.000; I2 = 0.0 %; P-heterogeneity = 0.977).
Creatinine levels increased significantly in studies that considered adjusted analysis based on covariates (3 trials, n = 152 participants, WMD = 0.070; 95 % CI: 0.027, 0.112 U/L; P = 0.001; I2 = 0.0 %; P-heterogeneity = 0.788).
Longer duration of intervention and normal daily dosages of N.S supplements led to significant reductions in ALP and AST concentrations, respectively, while higher daily dosages increased BUN levels.

In one study, Nigella sativa L. caused a significant decrease in weight (P=0.004) and body mass index (BMI) (P=0.002).
TSH levels were reported to be decreased and T3 increased in the treatment group (P =0.03) (P=0.008), respectively.
In another study on Nigella sativa L., results did not show a significant difference between the two groups (p=0.02).

High-quality large sample RCTs are necessary to confirm the benefit of NS supplementation for NAFLD.
Tang G et al. · Phytotherapy research : PTR (2021)
Mean differences (MD) or risk ratio (RR) and 95% confidence intervals (CI) were calculated.
Six articles from five trails with a total of 358 participants were included.
In summary, this study showed that NS supplementation was effective in the treatment of NAFLD and could improve the levels of ALT, AST, FBS, HDL, and hs-CRP in patients with NAFLD, as well as the severity of NAFLD.

Black seed supplementation appears to significantly improve FBG, HbA1c, TC, and LDL levels in patients with T2DM.
Karimi M et al. · Complementary therapies in medicine (2025)
Black seed supplementation appears to significantly improve FBG, HbA1c, TC, and LDL levels in patients with T2DM.
However, no significant effects were observed on other metabolic parameters, including insulin, TG, liver enzymes, kidney function, or body weight.
These findings suggest that black seed may be a beneficial adjunct therapy for glycemic and lipid control in T2DM patients but require further research to confirm its broader metabolic effects.

Finally, a total of 30 studies were found to be eligible for this meta-analysis.
Additional research, featuring extended durations and robust study designs, is necessary to determine the ideal dosage and duration of N. sativa supplementation for achieving a positive impact on glycemic markers.

The results revealed that N. sativa intake significantly decreased total cholesterol (SMD: -0.71; 95% CI, -1.44 to -0.38; p = 0.00), LDL-C (SMD: -1.06; 95% CI, -1.45 to -0.66; p = 0.00) and HDL-C (SMD: -0.31; 95% CI, 0.09 to 0.53; p = 0.01) concentrations.
In addition, N. sativa significantly decreased FBS (SMD: -0.8; 95% CI, -1.21 to -0.39; p = 0.00) and HbA1c (SMD: -0.37; 95% CI, -0.66 to -0.09; p = 0.01) concentrations.

In conclusion, dietary plant-derived essential oil compounds have potential anti-diabetic effects by influencing different signaling pathways and molecular targets linked to glucose metabolism, and should be safe and beneficial against diabetes and related complications.

They can also significantly inhibit the generation of TBARS and MDA, reduce oxidative stress, increase insulin levels, adiponectin, and glycoprotein enzymes, boost antioxidant enzymes like SOD, CAT, and GPx, as well as reduce glutathione and vital glycolytic enzymes.
Besides, they can significantly lower the levels of liver enzymes and lipid profile markers.
Moreover, most essential oil compounds are generally safe based on animal studies.
Therefore, there is a great need for further experimental studies to determine whether any nutritional interventions are beneficial in Hashimoto's disease.

These interventions improved antibody levels against peroxidase (anti-TPO), (thyrotropin) TSH, and free thyroxine (fT4).
No improvement was seen on the iodine-restricted diet.
Varied outcomes of analyzed dietary interventions may be due to the heterogeneous thyroid condition, high variability between patients, and differences in habitual intake of critical nutrients (e.g., iodine, selenium, and iron) in different populations.
