Organic Tart Cherry Powder
Also known as: Tart cherry, Montmorency cherry, Organic Tart Cherry Powder, Prunus cerasus
Overview
Organic Tart Cherry Powder is derived from tart cherries, particularly the Montmorency variety, and is rich in polyphenols and anthocyanins. It is used as a dietary supplement for its antioxidant and anti-inflammatory properties, with potential benefits for exercise recovery, inflammation reduction, sleep improvement, and cardiovascular health. Research includes numerous randomized controlled trials (RCTs) and meta-analyses, though variability in dosing and supplement characterization complicates comparisons. The quality of evidence is generally moderate, with some outcomes supported by meta-analytic data. It is available in various forms, including powder, concentrate, juice, and capsules. The powder form allows for standardized dosing of polyphenols if properly analyzed.
Benefits
- **Exercise Recovery:** Tart cherry supplementation shows small to moderate benefits in reducing muscle soreness (ES = -0.44) and improving recovery of muscular strength (ES = -0.78), muscular power (ES = -0.53), and jump height (ES = -0.82) after strenuous exercise. It also reduces inflammatory markers like CRP (ES = -0.46) and IL-6 (ES = -0.35)[1]. - **Inflammation and Cardiovascular Health:** Tart cherry intake can reduce serum CRP levels with moderate certainty (WMD: -0.39 mg/L) and may reduce TNF-α with very low certainty. Meta-analyses found no significant effects on blood pressure or heart rate[2]. - **Sleep:** Some evidence suggests tart cherry powder improves total sleep time and sleep efficiency, though data are less robust and require further confirmation[3]. - **Population-specific benefits:** Benefits have been demonstrated in healthy adults undergoing strenuous exercise and in adults with elevated inflammatory markers or risk factors.
How it works
Tart cherry powder's benefits are attributed to its high polyphenol and anthocyanin content, which act as antioxidants and anti-inflammatory agents. These compounds scavenge free radicals and modulate inflammatory cytokines such as IL-6 and TNF-α. Tart cherry may also influence nuclear receptors like PPARs, affecting lipid metabolism and inflammation. It acts on the musculoskeletal system by reducing exercise-induced muscle damage and inflammation, and it modulates systemic inflammatory response and oxidative stress markers. Potential effects on sleep regulation may be due to its melatonin content and antioxidant activity.
Side effects
Organic Tart Cherry Powder is generally recognized as safe with minimal side effects. The most commonly reported side effect is mild gastrointestinal discomfort, but this occurs in less than 5% of users. There are no well-documented drug interactions, but caution is advised when taken with anticoagulants due to the potential antiplatelet effects of polyphenols. There are no established contraindications, although individuals with cherry allergies should avoid it. Limited data are available for pregnant or lactating women, so use with caution is recommended. No serious adverse events have been reported in clinical trials.
Dosage
Effective dosages of tart cherry powder vary widely. Polyphenol doses in studies range from approximately 143 mg to over 2,000 mg per day, with anthocyanin doses ranging from 15 to 547 mg per day. Typical effective doses in RCTs include 30-60 ml of tart cherry concentrate or an equivalent powder providing approximately 300-600 mg of total polyphenols daily. Supplementation is often started several days before exercise and continued during recovery for optimal effects. Powder, concentrate, juice, and capsules are common forms. No established upper limit exists, but doses up to 2,140 mg polyphenols per day appear safe.
FAQs
Is tart cherry powder safe for daily use?
Yes, tart cherry powder is generally safe for daily use with minimal side effects reported in clinical trials.
How soon will I see benefits for muscle recovery?
Benefits for muscle recovery typically appear within days to a week of consistent supplementation around exercise periods.
Does tart cherry powder lower blood pressure?
Current evidence does not support significant blood pressure reduction with tart cherry powder supplementation.
Can tart cherry powder improve sleep?
Some evidence suggests that tart cherry powder may improve sleep quality, but more research is needed to confirm these findings.
Is a higher dose of tart cherry powder always better?
Higher doses may increase effects on inflammation, but optimal dosing requires further study to determine the most effective and safe amount.
Research Sources
- https://pubmed.ncbi.nlm.nih.gov/33440334/ – This systematic review and meta-analysis of 14 RCTs found that tart cherry supplementation led to small to moderate reductions in muscle soreness and improved recovery of strength and power after strenuous exercise. The study also reported reductions in inflammatory markers such as CRP and IL-6, suggesting a beneficial role in exercise recovery and inflammation management. The authors noted heterogeneity in dosing and exercise protocols as a limitation.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC10559679/ – This systematic review and dose-response meta-analysis of 21 RCTs examined the effects of tart cherry intake on cardiovascular risk factors and inflammation. The study found that tart cherry consumption reduced serum CRP levels with moderate certainty and possibly reduced TNF-α, but it had no significant effect on blood pressure or heart rate. The authors assessed the quality of evidence using the GRADE approach, noting moderate heterogeneity and some low-certainty outcomes.
- https://www.mdpi.com/2072-6643/16/23/4125 – This systematic review of 43 studies highlighted the variability in polyphenol content reporting in tart cherry supplements and confirmed the antioxidant and anti-inflammatory effects of tart cherry. The review emphasized the lack of standardization in supplement analysis and called for improved methodology in future research. It covered a wide range of populations and supplementation durations, underscoring the need for consistent analytical methods.
- https://www.tandfonline.com/doi/full/10.1186/s12970-015-0102-y – This study investigates the effect of tart cherry juice on markers of recovery and inflammation after marathon running. Results showed that runners who consumed tart cherry juice experienced a faster recovery of muscle function and reduced inflammation compared to the placebo group. This suggests that tart cherry juice can be an effective aid for athletes seeking to minimize muscle damage and inflammation following intense exercise.
- https://www.frontiersin.org/journals/nutrition/articles/10.3389/fnut.2021.652094/full – This research explores the impact of tart cherry supplementation on sleep and cognitive function in older adults with insomnia. The findings indicate that tart cherry consumption can improve sleep duration and efficiency, as well as enhance cognitive performance, particularly in memory tasks. These benefits are attributed to the antioxidant and anti-inflammatory properties of tart cherries, which may protect against age-related cognitive decline and sleep disturbances.
