1Cardiometabolic risk factorsMeta-AnalyseCited 6×n=1,685 · large study2025
Supplementation with PBE may ameliorate specific cardiometabolic risk factors, as indicated by reductions in body weight, DBP, SBP, FBS, LDL, and HbA1c levels.
Mohammadi S et al. · BMC complementary medicine and therapies (2025)
Supplementation with PBE may ameliorate specific cardiometabolic risk factors, as indicated by reductions in body weight, DBP, SBP, FBS, LDL, and HbA1c levels.
This approach can be regarded as an adjunct therapeutic strategy for CMS management.
Further high-quality trials with larger sample sizes and longer durations are required to validate these findings.
2ADHD symptom improvement with antioxidantsMeta-AnalyseCited 5×n=3,650 · very large study2024
The rankings of safety and efficacy of the 12 antioxidants vary.
Zhou P et al. · PloS one (2024)
The rankings of safety and efficacy of the 12 antioxidants vary.
Due to the low methodological quality of the included studies, the probability ranking cannot fully explain the clinical efficacy, and the results need to be interpreted with caution.
More high-quality studies are still needed to verify our findings.
4Adverse eventsMeta-AnalyseCited 47×n=7,690 · very large study2020
There is moderate-certainty evidence that phlebotonics probably reduce oedema slightly, compared to placebo; moderate-certainty evidence of little or no difference in QoL; and low-certainty evidence that these drugs do not influence ulcer healing.

Pooled data suggest that phlebotonics probably increase adverse events slightly, compared to placebo (RR 1.14, 95% CI 1.02 to 1.27; 37 studies; 5789 participants; moderate-certainty evidence).
There is moderate-certainty evidence that phlebotonics probably reduce oedema slightly, compared to placebo; moderate-certainty evidence of little or no difference in QoL; and low-certainty evidence that these drugs do not influence ulcer healing.
Moderate-certainty evidence suggests that phlebotonics are probably associated with a higher risk of adverse events than placebo.
5HbA1c reductionMeta-AnalyseCited 26×n=1,641 · large study2020
Small sample sizes, limited numbers of RCTs per condition, variation in outcome measures, and poor reporting of the included RCTs mean no definitive conclusions regarding the efficacy or safety of pine bark extract supplements are possible.

In a mixed group of participants with type 1 and type 2 DM we do not know whether pine bark extract decreases HbA1c (MD -0.20 %, 95% CI -1.83 to 1.43; one study; 67 participants; very low-certainty evidence).
We do not know whether pine bark extract increases bone alkaline phosphatase in post-menopausal women with osteopenia (MD 1.16 ug/L, 95% CI -2.37 to 4.69; one study; 40 participants; very low-certainty evidence).
Small sample sizes, limited numbers of RCTs per condition, variation in outcome measures, and poor reporting of the included RCTs mean no definitive conclusions regarding the efficacy or safety of pine bark extract supplements are possible.
6HDL cholesterol increaseMeta-AnalyseCited 12×n=1,065 · large study2019
Since there are few phytochemicals that have a significant increasing effect on HDL-C levels, pycnogenol may have important role in prevention of cardiovascular diseases.

Likely real
To estimate the effect size, changes in blood lipids were implemented.
A systematic review and meta-analysis of 14 clinical trials with 1,065 participants suggested a significant increase in plasma concentration of high density lipoprotein cholesterol (HDL-C; 3.27 mg/dL; 95% CI [0.19, 6.36]; p = 0.038).
Since there are few phytochemicals that have a significant increasing effect on HDL-C levels, pycnogenol may have important role in prevention of cardiovascular diseases.

9Biological, nutraceutical and clinical aspects of pine bark extractSystematische Übersicht2011
The objective of this paper is to review the current research on this extract in terms of extraction methods, its pharmacological, toxicological and nutraceutical effects and clinical studies.
Maimoona A et al. · Journal of ethnopharmacology (2011)
Bark extract of Pinus pinaster has a long history of ethnomedicinal use and is available commercially as herbal dietary supplement with proprietary name pycnogenol.
It is used as a food supplement to overcome many degenerative disorders.
Sixty-nine research articles were extracted, relating to its clinical, biological and nutraceutical aspects.
10Erectile dysfunction improvementMeta-AnalyseCited 35×n=540 · large study2019
The results of our systematic review and meta-analysis provide evidence on the effectiveness of arginine supplements for mild to moderate ED.

Likely real
The analysis demonstrated that arginine supplements with dosage ranging from 1,500 to 5,000 mg significantly improved ED compared with placebo or no treatment (odds ratios, 3.37 [1.29, 8.77], P = .01, I2 = 44).
Arginine supplements also caused significant improvements in the IIEF subdomain scores of overall satisfaction, intercourse satisfaction, orgasmic function, and erectile function, whereas the IIEF sexual desire score remain unchanged.
The adverse effect rate in the arginine-treated group was 8.3%, and that in the placebo group was 2.3%, none of which were severe.
11Sexual function in erectile dysfunctionMeta-AnalyseCited 5×n=184 · medium study2023
These results indicate that the combination of PAL may have a significant effect on improving sexual function in patients with mild to moderate ED.
Tian Y et al. · Frontiers in endocrinology (2023)
These results indicate that the combination of PAL may have a significant effect on improving sexual function in patients with mild to moderate ED.
This study will provide clinicians with more options for treating patients with ED.
More randomized controlled trials are needed in the future to further demonstrate the effect of combination therapy on sexual function in patients with ED.
Current evidence supports the use of ginger and turmeric for glycaemic control in type 2 diabetes, however, given the high clinical heterogeneity and low quality of the review, our confidence in this finding is somewhat limited.

Ginger, turmeric, and Jinlida granules significantly decreased HbA1c compared to placebo (mean differences (MD): -0.467%, -0.486%, -0.283%, respectively) with moderate to high certainty evidence.
Current evidence supports the use of ginger and turmeric for glycaemic control in type 2 diabetes, however, given the high clinical heterogeneity and low quality of the review, our confidence in this finding is somewhat limited.
Herbal medicines should be used only as an adjunct to conventional treatment, with shared decision-making between clinicians and patients.
Further, high quality randomized clinical trials are needed to confirm this result.
Pourmasoumi M et al. · Phytotherapy research : PTR (2020)
Pooled analysis suggested that pycnogenol supplementation can reduced systolic blood pressure (SBP) of (-3.22 mmHg; 95% CI [-5.52, -0.92]) and diastolic blood pressure (DBP; -1.91 mmHg; 95% CI [-3.64, -0.18]).
Effect of pycnogenol on SBP was more pronounce in subgroup in which pycnogenol was administered along with other treatments.
A significant effect of pycnogenol on DBP in studies with >12-week duration, whereas this favorable effect was not observed in subgroup with ≤12-week supplementation.
Currently the scientific evidence is insufficiently robust to establish definitive clinical practice guidelines, but processes could be established to track the impact of these ingredients.
Crawford C et al. · Pain medicine (Malden, Mass.) (2019)
Currently the scientific evidence is insufficiently robust to establish definitive clinical practice guidelines, but processes could be established to track the impact of these ingredients.
Until then, providers have the evidence needed to make informed decisions about the safe use of these dietary ingredients, and future research can address existing gaps.
The overall analysis including all trials showed that supplements provided moderate and clinically meaningful treatment effects on pain and function in patients with hand, hip or knee osteoarthritis at short term, although the quality of evidence was very low.
Liu X et al. · British journal of sports medicine (2018)
Another six (undenatured type II collagen, avocado soybean unsaponifiables, methylsulfonylmethane, diacerein, glucosamine and chondroitin) revealed statistically significant improvements on pain, but were of unclear clinical importance.
Chondroitin demonstrated statistically significant, but not clinically important structural improvement (effect size -0.30, -0.42 to -0.17).
