Conditions studied: Cognition Disorders in Old Age

In brief

The goal of this clinical trial is to learn if two food supplements based on olive leaf extract, alone or combined with mullein extract, help maintain cognitive function in older adults with mild cognitive impairment (MCI). It will also evaluate their safety. The main questions it aims to answer are: Do the supplements improve or help maintain cognitive function (such as memory and attention)? Do participants experience any side effects when taking the supplements? Researchers will compare two active supplements to a placebo (a look-alike substance with no active ingredients) to see if the supplements are effective. Participants will: Take either one of the two supplements or a placebo every day for 6 months Take 2 capsules per day, preferably between meals, with a small amount of water Visit the clinic at the start of the study, after 3 months, and after 6 months for cognitive assessments Complete questionnaires to evaluate cognitive function and quality of life Be monitored throughout the study for any side effects
