Trial Summary
What is the purpose of this trial?To examine the effects of once daily supplementation with 500mg VeriSperse® resveratrol (VRES) for 17 days on muscle function, delayed onset muscle soreness, systemic concentrations of muscular damage markers and markers of oxidative stress in resistance trained young adult males following a damaging isoinertial squat protocol (ISP).
What safety data is available for resveratrol?The safety data for resveratrol, including its cis and trans isomers, is limited but suggests some biological activity. Studies have shown that resveratrol can decrease platelet aggregation and has antioxidant, anti-inflammatory, and anticarcinogenic properties. However, the cis isomer is not commercially available and less is known about its pharmacological activity. Resveratrol is incorporated into blood cells and lipoproteins, and its metabolism has been studied in humans, rats, and mice. Overall, while resveratrol shows potential health benefits, comprehensive safety data, especially for the cis isomer, is still lacking.13469
Do I have to stop taking my current medications for the trial?The trial requires participants to stop taking any performance-enhancing drugs and nutritional supplements known to improve physical performance, with a 28-day washout period before starting the study. Regular use of prescription or over-the-counter medications that affect performance is also not allowed. The protocol does not specify other medications, but you may need to discuss your current medications with the study team.
Is resveratrol a promising treatment for exercise performance and recovery?Yes, resveratrol is a promising treatment because it can improve exercise endurance and muscle function, and it has beneficial effects on heart health and inflammation.236710
What data supports the idea that Resveratrol for Exercise Performance and Recovery is an effective treatment?The available research does not provide direct evidence supporting the effectiveness of Resveratrol for Exercise Performance and Recovery. The studies focus on its antioxidant properties, effects on blood components, and bioavailability in humans. For example, one study shows that trans-resveratrol has anti-inflammatory and cancer-preventive properties, while another highlights its ability to decrease platelet aggregation. However, these findings are not directly related to exercise performance or recovery. Therefore, more specific research is needed to determine its effectiveness for this purpose.13568

Antiplatelet activity of cis-resveratrol. [2018]The anti-aggregating effect of cis-resveratrol (cis-3,4,5- trihydroxystilbene) has been evaluated in vitro in different concentrations on platelet-rich plasma from health volunteers. Cis-resveratrol at the concentration of 1 x 10(-5) and 1 x 10(-6) M was able to decrease collagen-induced platelet aggregation by 43.5 +/-11.4% and 26.8 +/- 14.6%, while trans-resveratrol at the same concentration showed a slightly lower activity. In view of the behaviour of these two isomers in biological fluids, the evaluation of resveratrol activity in animals and humans take into account the total amount of the two isomers.
Contents of resveratrol, piceid, and their isomers in commercially available wines made from grapes cultivated in Japan. [2019]The presence of resveratrol (3,5,4'-trihydroxystilbene) and its beta-glucoside, piceid (resveratrol-3-beta-D-glucopyranoside), together with their isomers in wine appears to be one of the beneficial factors conferring a protective effect against cardiovascular disease through red wine ingestion. A total of 42 red and white wines was collected in areas from Hokkaido to Kyushu in Japan. The wines were fractionated with a C18 Sep-pak cartridge, and the active principles were eluted with ethyl acetate. Crude trans- and cis-piceid were extracted from a Chinese medicine, 'Kojohkon' (Polygonum cuspidatum), and their retention times and UV absorption were confirmed by HPLC. trans- and cis-Resveratrol, and trans- and cis-piceid were analyzed in a short C18 HPLC column, and cis-resveratrol was quantified from the amount of cis-isomer converted from authentic trans-resveratrol that had been treated by UV irradiation. The content of piceid is shown as the resveratrol equivalent. The average content of total stilbene compounds was 4.37 mg/liter in red wines, while only 0.68 mg/liter in white wines. Red wines made from Pinot noir, Merlot, and Zweigeltrebe grapes all had a high resveratrol content.
Gas chromatographic analysis of resveratrol in plasma, lipoproteins and cells after in vitro incubations. [2019]Resveratrol is a trihydroxystilbene present in certain red wines. It may play a role in the inhibition of lipoprotein oxidation and platelet activity. We have developed the first method to measure resveratrol in animal and human samples and to study its incorporation in vitro. After adding epicoprostanol as an internal standard, samples are subjected to lipid extraction in the presence of antioxidant and under dim light to minimize both denaturation and isomerization of the trans-resveratrol to the cis-form. Extracts were purified by cold acetone precipitation and the resveratrol-containing acetone phase was evaporated under nitrogen. The resveratrol was analyzed as a trimethylsilyl derivative by capillary gas chromatography which resolved the cis- and trans-resveratrol (6.6 and 12.9 min, respectively). Analyses of samples spiked with pure trans-resveratrol (0.1 to 10 microg) indicated that the method was specific and gave excellent linearity and recovery (96.8%) with a high reproducibility (coefficient of variation: 3.3%). The detection limit was about 50 ng/ml. Applications show that resveratrol was incorporated into blood cells and lipoproteins after in vitro incubations with plasma, lipoproteins and cells.
Human, rat, and mouse metabolism of resveratrol. [2019]Resveratrol, a phenolic phytoalexin occurring in grapes, wine, peanuts, and cranberries, has been reported to have anticarcinogenic, antioxidative, phytoestrogenic, and cardioprotective activities. Because little is known about the metabolism of this potentially important compound, the in vitro and in vivo metabolism of trans-resveratrol were investigated.
Bioavailability of trans-resveratrol from red wine in humans. [2018]Many in vitro studies demonstrated significant biological effects of trans-resveratrol. Thus, understanding the rate of intestinal absorption and metabolization in vivo of trans-resveratrol is the prerequisite to evaluate its potential health impact. Bioavailability studies mainly in animals or in humans using the pure compound at very high doses were performed. In this work, trans-resveratrol bioavailability from a moderate consumption of red wine in 25 healthy humans has been studied by three different experiments. The wine ingestion was associated to three different dietary approaches: fasting, a standard meal, a meal with high and low amount of lipids. Trans-resveratrol 3- and 4'-glucuronides were synthesized, purified, and characterized as pure standards. Bioavailability data were obtained by measuring the concentration of free, 3-glucuronide and 4'-glucuronide trans-resveratrol by high-performance liquid chromatography (HPLC), both with ultraviolet (UV) and mass spectrometry (MS) detection, in serum samples taken at different times after red wine administration. Free trans-resveratrol was found, in trace amounts, only in some serum samples collected 30 min after red wine ingestion while after longer times resveratrol glucuronides predominated. Trans-resveratrol bioavailability was shown to be independent from the meal or its lipid content. The finding in human serum of trans-resveratrol glucuronides, rather than the free form of the compound, with a high interindividual variability, raises some doubts about the health effects of dietary resveratrol consumption and suggests that the benefits associated to red wine consumption could be probably due to the whole antioxidant pool present in red wine.
Comparative studies of the antioxidant effects of cis- and trans-resveratrol. [2022]Resveratrol (3,4',5-trihydroxystilbene, RESV) is a natural phenolic compound that exists as cis and trans isomers [c-RESV or (Z)-RESV and t-RESV or (E)-RESV, respectively]. t-RESV is a natural component of Vitis vinifera L. (Vitaceae), abundant in the skin of grapes (but not in the flesh) and in the leaf epidermis, and present in wines, especially red wines. In in vitro, ex vivo and in vivo experiments t-RESV exhibits a number of biological activities, including anti-inflammatory and anticarcinogenic properties. RESV also exists in wines as a cis isomer, which (unlike t-RESV) is not currently available commercially; as a result, little is known about this isomer's pharmacological activity. In this review, I will focus on the few comparative studies of the antioxidant effects of the two RESV isomers in different experimental models.
Determination of trans- and cis-resveratrol in Serbian commercial wines. [2019]Resveratrol (trans-3,5,4'-trihydroxystilbene) is a phytoalexin produced by grapevines in response to fungal infection, particularly to Botrytis cinerea. It has been shown that it possess various biological effects such as prevention of cardiovascular diseases and anti-inflammatory and anticancerogenic properties. Red wines are a primary source of resveratrol. Although a number of investigations have focused on the determination of resveratrol in wines of different countries, there is no similar study about the wines produced in Serbia. As authors are aware, the only study concerning resveratrol content in wine in the Balkan region was conducted in Greece. In this study, the trans- and cis-resveratrol content in samples obtained from 18 commercial Serbian wines (10 red, 7 white, and 1 rose) were analyzed. Analyses were performed after solid-phase extraction by high-performance liquid chromatography with a diode array detection system using an RP-C(18) column with gradient elution [solvent A: acetonitrile-acetic acid-water (20:2:78 v/v), solvent B: acetonitrile-acetic acid-water (90:2:8 v/v)]. Detection of trans- and cis-resveratrol was performed on 306 and 286 nm, respectively. It was clearly established that there was a presence of trans-resveratrol isomers in all analyzed wines (0.11-1.69 mg/L) except in one white wine. Cis-resveratrol was present in 12 from 18 samples in different amounts (0.12-1.49 mg/L).
Steady-State pharmacokinetics and tolerability of trans-resveratrol 2000 mg twice daily with food, quercetin and alcohol (ethanol) in healthy human subjects. [2021]Trans-resveratrol is a polyphenol, which is found in red wine and has cancer chemo-preventive properties and disease-preventive properties. The pharmacokinetics of trans-resveratrol have been investigated in single-dose studies and in studies with relatively low dosages. The present study aimed to investigate the steady-state pharmacokinetics and tolerability of trans-resveratrol 2000 mg twice daily with food, quercetin and alcohol (ethanol).
Anti-tumor properties of cis-resveratrol methylated analogs in metastatic mouse melanoma cells. [2018]Resveratrol (E-3,5,4'-trihydroxystilbene) is a polyphenol found in red wine that has been shown to have multiple anti-cancer properties. Although cis-(Z)- and trans-(E)-isomers of resveratrol occur in nature, the cis form is not biologically active. However, methylation at key positions of the cis form results in more potent anti-cancer properties. This study determined that synthetic cis-polymethoxystilbenes (methylated analogs of cis-resveratrol) inhibited cancer-related phenotypes of metastatic B16 F10 and non-metastatic B16 F1 mouse melanoma cells. In contrast with cis- or trans-resveratrol and trans-polymethoxystilbene which were ineffective at 10 μM, cis-polymethoxystilbenes inhibited motility and proliferation of melanoma cells with low micromolar specificity (IC50
Effect of Resveratrol on Walking Performance in Older People With Peripheral Artery Disease: The RESTORE Randomized Clinical Trial. [2019]Research shows that resveratrol, a sirtuin activator in red wine, improves exercise endurance and skeletal-muscle oxidative metabolism in animals and may enhance vascular function in humans. Resveratrol supplement sales exceed $30 million annually in the United States, but few data are available regarding its efficacy in humans.
