The goal of this clinical trial is to determine whether the extra-virgin olive oil (EVOO) phenolic dietary supplement can improve memory function and modulate biomarkers among individuals with mild cognitive impairment (MCI). The main questions it aims to answer are:
* Does dietary supplementation with EVOO phenolics improve cognitive function? * What would be the effect of the EVOO dietary supplement on other MCI-related biomarkers, including vascular function and biological pathways?
Researchers will compare the EVOO dietary supplements with a placebo (a look-alike substance that contains no EVOO phenolics)
Participants will:
* Take EVOO dietary supplements or a placebo daily for 6 months * Visit the study site during the 6-month study for screening and testing.
