CherryPURE (Prunus avium)

CherryPURE is a concentrated Montmorency tart cherry (Prunus avium) extract standardized for anthocyanins, particularly cyanidin-3-glucoside and cyanidin-3-rutinoside, which drive its antioxidant and anti-inflammatory activity. These polyphenols inhibit cyclooxygenase enzymes (COX-1 and COX-2) and neutralize free radicals, supporting exercise recovery and oxidative stress reduction.

Origin & History

CherryPURE is a branded standardized extract derived from Prunus avium L. (sweet cherry), a deciduous tree native to Europe and western Asia. It is produced through solvent extraction methods using ethanol-water mixtures (70:30 v/v) via heat-reflux or accelerated solvent extraction at 70°C to isolate phenolic compounds from cherry fruits, branches, or waste materials.

Historical & Cultural Context

Prunus avium (sweet cherry) has historical use in traditional medicine for cough suppression, nervous irritability, and dyspepsia, attributed to the cyanogenic glucoside prunasin. Modern interest focuses primarily on waste valorization for antioxidant compounds rather than traditional medicinal applications.

Health Benefits

• Antioxidant activity demonstrated in laboratory studies with reducing power of 11.9 mg AAE/g and DPPH radical scavenging of 16.8 mg TE/g (preliminary evidence only)
• Potential antimicrobial effects from branch extracts shown in vitro (no human data available)
• Traditional use for cough suppression attributed to cyanogenic glucoside content (no clinical validation)
• May support nervous system based on historical use for nervous irritability (traditional evidence only)
• Possible digestive support historically used for dyspepsia (no modern clinical evidence)

How It Works

CherryPURE's primary bioactives, cyanidin-3-glucoside and cyanidin-3-rutinoside, inhibit cyclooxygenase-1 and cyclooxygenase-2 enzymes, reducing prostaglandin synthesis and dampening the inflammatory cascade. These anthocyanins also scavenge reactive oxygen species (ROS) directly, with in vitro data showing a DPPH radical scavenging capacity of 16.8 mg Trolox equivalents per gram and a reducing power of 11.9 mg ascorbic acid equivalents per gram. Additionally, anthocyanins may modulate NF-κB signaling, further suppressing pro-inflammatory cytokine expression at the transcriptional level.

Scientific Research

No human clinical trials, RCTs, or meta-analyses specifically on CherryPURE were identified in the available research. Current evidence is limited to in vitro antioxidant activity studies showing total phenolic content of 14.6 mg GAE/g and total flavonoid content of 24.8 mg QE/g in cherry waste extracts.

Clinical Summary

In vitro laboratory studies confirm CherryPURE's antioxidant potency, measuring DPPH radical scavenging at 16.8 mg TE/g and reducing power at 11.9 mg AAE/g, though these results do not directly translate to human bioavailability. Human clinical data on CherryPURE as a branded ingredient remains limited, but research on Montmorency tart cherry concentrates generally suggests benefits for post-exercise muscle recovery and inflammation reduction in small trials (typically 10–54 participants). Branch extracts have shown antimicrobial activity against select bacterial strains in vitro, with no human trials currently validating this application. Overall, evidence is preliminary-to-moderate; larger randomized controlled trials are needed to establish definitive efficacy and optimal dosing.

Nutritional Profile

CherryPURE (Prunus avium) is a concentrated tart cherry powder standardized to high anthocyanin content. Key bioactive compounds include anthocyanins (primarily cyanidin-3-glucoside and cyanidin-3-rutinoside) at approximately 50-60 mg per gram of concentrate, representing a significant concentration uplift versus whole fruit (whole sweet cherries contain ~82-297 mg anthocyanins per 100g fresh weight). Contains polyphenols including quercetin (~7-9 mg/100g fresh fruit equivalent), chlorogenic acid, and hydroxycinnamic acids contributing to the measured antioxidant reducing power of 11.9 mg AAE/g and DPPH radical scavenging of 16.8 mg TE/g. Cyanogenic glucosides (primarily prunasin and amygdalin) are present predominantly in bark and seed fractions; fruit flesh concentrations are markedly lower and considered negligible at typical serving doses. Melatonin is naturally present in Prunus avium at approximately 0.1-13 ng/g fresh weight, which may contribute to nervous system support claims. Carbohydrate content in the powdered concentrate is primarily from fruit sugars (glucose, fructose, sorbitol); fiber content is minimal post-processing. Micronutrient contribution at typical supplement doses (480-500 mg powder) is limited: trace potassium (~10-15 mg/dose), vitamin C (~1-2 mg/dose). Bioavailability of anthocyanins from cherry sources is generally low (estimated 1-5% absorption), though cyanidin-3-rutinoside demonstrates moderate intestinal uptake; co-ingestion with food may modestly improve absorption via slowed gastric transit.

Preparation & Dosage

No clinically studied dosage ranges for CherryPURE in humans have been established. Laboratory extraction studies used 825 mg plant material in 36 mL 70% ethanol, but no standardization for commercial forms exists. Consult a healthcare provider before starting any new supplement.

Synergy & Pairings

Vitamin C, quercetin, grape seed extract, resveratrol, green tea extract

Safety & Interactions

CherryPURE is generally considered safe for most healthy adults when used as directed, with tart cherry products having a long history of food use and no serious adverse events reported at typical supplement doses. Individuals taking anticoagulants such as warfarin should exercise caution, as anthocyanins may have mild platelet-inhibiting properties that could potentiate bleeding risk. Those with known salicylate sensitivity should note that cherries contain natural salicylates, which may trigger reactions in sensitive individuals. Safety data during pregnancy and lactation is insufficient, so use during these periods should be avoided without medical supervision.
