The Claim
Daily supplementation with 300 mg of a standardized polyphenol-rich grape and blueberry extract (Memophenol™) for 24 weeks significantly improves the speed of information processing by 9.53% in adults aged 60–80 with mild cognitive impairment compared to placebo.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults aged 60–80 with mild cognitive impairment, taking 300 mg of a standardized grape and blueberry extract daily for 24 weeks results in a 9.53% increase in the speed of information processing compared to taking a placebo.
See the scientific wording
Supplementation with 300 mg daily of a standardized polyphenol-rich grape and blueberry extract (Memophenol™) for 24 weeks significantly improves the speed of information processing by 9.53% in adults aged 60–80 with mild cognitive impairment, compared to placebo, suggesting a potential benefit for cognitive processing efficiency in this population.
Polyphenols from grape and blueberry extract increase blood flow in the brain, which delivers more oxygen and nutrients to nerve cells. This helps nerve cells communicate faster and more efficiently, making the brain process information quicker.
What the research says
1 studyThis study found that older adults with mild memory problems who took a grape and blueberry supplement for six months got noticeably faster at reacting to cognitive tasks, compared to those who took a placebo. So yes, the supplement helped them think quicker on these tasks.
