    Polyphenols have been shown to have neuroprotective effects. The present secondary research titled as a critical review: Effect of polyphenol supplementation on cognitive function in older adults, aimed to identify the benefits of polyphenol supplementation on cognitive function in older adults. The clinical question was: Does polyphenol supplementation improve cognitive function in older adults? The Evidence-Based Nutrition (NuBE) methodology was used. The search was carried out in the descriptors PubMed, Scielo, Dialnet, Science Direct, finding 298 articles. Ten articles were selected and evaluated with the CASPe critical reading tool, finally choosing the article titled “A Randomized, Double-Blinded, Clinical Trial on Effects of a Vitis vinifera Extract on Cognitive Function in Healthy Older Adults.” The critical commentary allowed us to conclude that supplementation with the polyphenols proanthocyanidins and anthocyanidins from the extract of the Vitis vinifera grape variety improves some cognitive domains in older adults; however, further studies are required to clarify the underlying mechanisms and recommended doses.
