As global population aging accelerates, age-related conditions such as cardiovascular disease and cognitive decline are becoming increasingly prevalent. Oxidative stress and vascular dysfunction are recognized as central mechanisms contributing to neurodegeneration. Dietary antioxidants, particularly anthocyanins, have attracted growing attention for their potential to protect neuronal integrity and support cerebral blood flow. Aronia melanocarpa (chokeberry), a berry exceptionally rich in polyphenols and anthocyanins, has demonstrated promising biological activity. Recent clinical research suggests that supplementation with Aronia extract may improve brain vascular function and cognitive performance in older adults with overweight or obesity. This article reviews current findings on Aronia’s bioactive components, physiological functions, and expanding applications, while maintaining a cautious and evidence-based perspective.
Population aging refers to the social phenomenon in which the proportion of elderly individuals in the total population continues to increase. According to a 2023 United Nations report, the global population aged 65 and above is projected to reach 1.6 billion by 2050, approximately double that of 2023. As the degree of population aging deepens, the prevalence of age-related diseases, especially cardiovascular diseases and cognitive disorders, is also rising.
Oxidative stress and vascular dysfunction are considered core mechanisms leading to neural damage. Antioxidants can effectively inhibit oxidative injury and inflammatory responses in neurons by scavenging free radicals, thereby protecting the integrity of the brain’s microstructure. At the same time, by maintaining vascular endothelial function and promoting cerebral blood circulation, antioxidants help ensure adequate oxygen and nutrient supply for neural metabolism. Through these dual pathways—cellular protection and hemodynamic regulation—cognitive function may be significantly improved.
Against this background, dietary anthocyanins have attracted increasing attention due to their strong antioxidant properties, particularly regarding their potential cognitive benefits. Multiple studies suggest that regular consumption of anthocyanin-rich foods may have a positive impact on cognitive function.
Aronia melanocarpa is a berry with a dark purple-black skin and deep red flesh, rich in polyphenolic compounds, especially anthocyanins. Research indicates that every 100 grams of Aronia fruit contains 1,752 mg of polyphenols, of which proanthocyanidins account for 1,480 mg—far higher than in other common berries such as blackcurrant, blackberry, and cranberry—thus providing stronger antioxidant capacity.
Recently, a randomized, double-blind, placebo-controlled, crossover study published in the journal Clinical Nutrition found that daily supplementation with 160 mg of Aronia melanocarpa extract (AME) significantly improved brain vascular function and cognitive performance in overweight and obese older adults.

Brain Blood Flow and Cognitive Performance Findings
10.8% Reduction in Regional Cerebral Blood Flow, 20% Improvement in Cognitive Performance
The study included 30 healthy overweight or obese older adults aged 59–71 years, with a BMI of 26–31.4. Participants consumed either 160 mg of AME or a placebo daily before breakfast. The AME used in the study contained 25% anthocyanins, including 17% cyanidin-3-O-galactoside and 8% other cyanidin-3-glycosides.
After 6 weeks of intervention, a significant reduction in cerebral blood flow was observed in a specific brain cluster among participants taking AME, with an average decrease of 4.4 mL/100 g/min (10.8%). This region was mainly located in the right insular cortex (probability of localization 30.8%), with partial extension into the temporal lobe (9.8%), orbitofrontal cortex (4.0%), and temporal pole planum (1.8%). These changes suggest that AME may influence cognitive function by modulating neurovascular activity in specific brain regions.

In terms of cognitive performance, after AME supplementation, participants showed significant improvement in spatial working memory tests, with approximately a 20% reduction in errors, indicating enhanced executive function, particularly in spatial working memory and information processing.

Notably, AME has also demonstrated cognitive benefits in healthy populations. Clinical studies show that daily supplementation with 90 mg of AME for 24 weeks significantly improved psychomotor speed in healthy middle-aged adults. In healthy young adults, supplementation with 750 mg of AME daily for just one week resulted in noticeable improvements in attention and psychomotor speed.
The European-Origin “Longevity Berry”
Aronia melanocarpa, also known as black chokeberry and sometimes referred to as the “longevity berry,” is a deciduous shrub in the Rosaceae family. It is native to moist forests and wetlands in eastern North America. China began introducing Aronia cultivation in some regions in 2005, and it is now grown in several provinces including Liaoning, Jiangsu, Zhejiang, and Jilin. In 2018, black chokeberry fruit was approved as a novel food ingredient in China.
Aronia fruit is rich in various bioactive compounds such as proanthocyanidins, phenolic acids, triterpenoids, cyanidin-3-O-galactoside, chlorogenic acid, and quercetin, contributing to physiological functions including antioxidant, anti-inflammatory, and blood glucose–lowering effects.
1) Antioxidant Effects
Studies show that Aronia polyphenols can scavenge DPPH free radicals, ABTS radicals, and superoxide anion radicals, and can inhibit the activity of 15-lipoxygenase and xanthine oxidase. As concentration increases, antioxidant activity also increases, and its antioxidant capacity may even surpass that of vitamin C. In addition, anthocyanin-3-galactoside, anthocyanin-3-glucoside, and anthocyanin-3-arabinoside extracted from Aronia exhibit strong DPPH radical scavenging activity.
2) Cardiovascular Protection
Research suggests that Aronia can reduce oxidative stress and inflammatory gene expression, thereby lowering levels of triglycerides, total cholesterol, and low-density lipoprotein cholesterol. This helps improve lipid balance in individuals with metabolic syndrome and may contribute to the prevention of cardiovascular disease.
3) Blood Glucose Regulation
An acute intervention study in healthy subjects showed that drinking 100 mL of Aronia juice before meals significantly suppressed postprandial blood glucose elevation. Long-term studies also indicate that consuming 200 mL of Aronia juice twice daily for three consecutive months significantly reduced fasting blood glucose, glycated hemoglobin, and cholesterol levels, and helped improve blood pressure. These findings suggest that Aronia has promising potential in supporting the management of type 2 diabetes and related metabolic markers.
Expanding Applications of Aronia
Aronia berries have a long history of consumption in Europe, Asia, and North America, where they are mainly used to produce colorants, syrups, juices, jams, and fruit wines.
Today, growing consumer awareness of Aronia’s health benefits has promoted rapid market development for Aronia extracts. According to WISE GUY data, the Aronia extract market was valued at USD 6.19 billion in 2024 and is projected to grow to USD 11.5 billion by 2032, with a compound annual growth rate of approximately 8.06% from 2025 to 2032. In North America, Aronia products have also been developed into a variety of dietary supplements.
