Einfach gesagt: In conclusion, bilberry and blackcurrant extract appears effective in lowering HbA1c and total and LDL cholesterol, whereas grape seed extract may lower total and LDL cholesterol, and blood pressure, in specific population groups.
Grohmann T et al. · Nutrients (2021)
Intervention with grape seed extract may reduce systolic and diastolic blood pressure in subjects with hypertension or metabolic syndrome.
Differential responsiveness in cholesterol and blood pressure outcomes between stratified populations could not be explained by age, dose or study duration.

However, contradictory results as regard the efficacy of some supplements such as Allium sativum, Juglans regia, and Lycium barbarum on glucose homeostasis have emerged from some clinical studies.
Further studies are also required for Cinnamomum, Cynara scolymus, Momordica charantia, Olea europaea, and Opuntia streptacantha.

Einfach gesagt: Further studies are needed to explore the bioavailability of encapsulated polyphenols, especially in the functional food context.
Ali Redha A, Kodikara C, Cozzolino D. · Nutrients (2024)
Encapsulation has been an effective technique in improving the bioavailability of individual polyphenols like hesperidin, fisetin, and curcumin.
However, this approach has not yielded consistent results when applied to groups of polyphenols, such as bilberry anthocyanins or cocoa phenolic acids.
Encapsulation by micellization has shown promising results in improving the bioavailability of curcumin in a nutraceutical context.
6Antiaging effects of bilberry compoundsÜbersicht2026
Einfach gesagt: This review offers a summary of the existing information on the antiaging potential of bilberry fruits and leaves, and analytically reviews the outcome of clinical trials, with special attention towards its medicinal properties.

It is also stated to promote antioxidant defense and lower oxidative stress, having antiaging, anti-inflammatory, lipid-lowering, antimicrobial effects, lowering blood glucose and other age-related diseases, etc.
Reports suggest that apart from the fruit, the leaves of bilberry are equally rich in numerous bioactive compounds of medicinal importance.
This current review offers valuable insights on bilberry fruits, leaves, and extracts, providing an inclusive assessment of their bioactive compound configuration, related biological prospects, and the extraction methodology of their major compounds.

At D84, the wrinkle depth had decreased by 10.6%, Ra had improved by 7.9%, Rz had decreased by 7.3%, R0 had improved by 13.3%, R2 had improved by 12.4%, and skin antioxidant capacity had increased by 20.8%.
ITA° increased by 20.8% and was accompanied by a decrease in the skin's redness component by 16.8% and an increase in the lightness component by 2.2%.
The variation of all the above-mentioned parameters was statistically significant between the FBE and PL groups.
11High-frequency component (HFC)-1 valueRCTn=109 · medium study2020
Einfach gesagt: This study shows that oral consumption of 240 mg SBE extract for 12 weeks relieves the tonic accommodation of the ciliary muscle caused by VDT tasks and near-vision tasks.
Kosehira M et al. · Nutrients (2020)
Likely real
Results showed that post-load HFC-1 values at weeks 8 and 12 were significantly improved in the SBE group than in the placebo group (p = 0.014 and 0.017, respectively).
Regarding the difference between before and after the task load (ΔHFC-1), the values were significantly better in the SBE group than in the placebo group at week 4 and 12 (p = 0.018 and 0.049, respectively).
Tests were performed before and after VDT tasks at week 0, 4, 8, and 12; high-frequency component (HFC)-1 value was the evaluation outcome.

Borderline
Compared to controls, the anthocyanin group exhibited significant decreases (P < 0.05, all comparisons) in plasma alanine aminotransferase (-19.1% vs 3.1%), cytokeratin-18 M30 fragment (-8.8% vs 5.6%) and myeloperoxidase (-75.0% vs -44.8%).
Significant decreases from baseline in fasting blood glucose and homeostasis model assessment for insulin resistance were observed in the anthocyanin group; however, these differences were not significant relative to placebo controls.
