A clinical study found that a daily 200-milligram dose of coffee cherry extract improved memory, attention and accuracy both immediately and over several weeks, even when testing was conducted in real-world conditions.

A decaffeinated extract derived from coffee cherries significantly improved memory performance, focus and accuracy in adults ages 40 to 65, according to a study published in the journal Nutrients, adding to growing research on plant-based compounds and cognitive health.
The study evaluated the effects of a 200-milligram dose of whole coffee cherry extract, known as CCE, compared with a placebo. Researchers reported that participants who received the extract demonstrated faster cognitive processing, improved attention control and fewer memory errors, with benefits observed both one hour after supplementation and after 28 days of continued use.
Unlike caffeine, which is concentrated in coffee beans and produces short-term stimulation, coffee cherry extract is rich in polyphenols—bioactive compounds associated with reduced inflammation and improved neural efficiency. Researchers noted that these compounds may support brain function without the stimulant effects commonly associated with coffee consumption.
Participants completed cognitive assessments remotely from their homes rather than in a laboratory environment, allowing researchers to evaluate performance under everyday conditions that included normal distractions. The tests included a working-memory task requiring participants to recall sequences of visual shapes, as well as an impulse-control task designed to measure attention and response inhibition.
Results showed that one hour after a single dose, participants receiving CCE made approximately 80% fewer memory errors and demonstrated an 11% improvement in accuracy compared with those receiving a placebo. After 28 days of supplementation, accuracy scores were 28% higher, and false responses declined by 64%, indicating sustained improvements rather than short-lived effects.
Researchers highlighted the remote testing design as a strength of the study, noting that it more closely reflects how cognitive performance functions in daily life compared with tightly controlled laboratory settings. The findings suggest that the extract’s benefits are not limited to artificial testing environments.
The study also explored potential biological mechanisms behind the cognitive improvements. Researchers pointed to evidence suggesting that CCE may increase levels of brain-derived neurotrophic factor, or BDNF, a protein involved in neuron growth, learning, memory formation and long-term brain health. Low levels of BDNF have been associated in prior research with cognitive decline and certain neurological and mental health disorders.
Because the extract is caffeine-free, researchers noted that it may be suitable for individuals who are sensitive to stimulants or who wish to avoid caffeine-related side effects. While the findings are limited to the specific dose and duration studied, the authors said future research will focus on optimal dosing strategies and further investigation into the biological pathways involved.
As concerns about age-related cognitive decline continue to grow, the study adds evidence that compounds derived from commonly consumed plants may play a role in supporting brain function across midlife and beyond.
