Conditions
Summary
The goal of this study is to learn if an olive oil extract works to improve knee pain and discomfort in adults. The main questions it aims to answer are: 1) Does the olive oil extract improve the perceptions of knee pain and discomfort, and 2) Does the olive oil extract improve knee function in adults? The main procedures in the study include: * Screening and informed consent * Take one assigned study capsule (supplement or placebo) daily with food for 6 weeks * Complete digital questionnaires about your knee pain, stiffness, and function at scheduled times * Complete a Day 1 acute assessment and two simple functional movement tests at home as described below * If possible, connect a compatible wearable device to allow collection of sleep and physical activity data as detailed below. * Collect saliva samples at home using a provided kit at designated timepoints * Record any pain medications taken during the study or any side effects

Interventions
The investigational product is an olive oil extract dietary supplement formulated for oral consumption. The product is provided in capsule form and is intended for general wellness use, including support of joint comfort and function. Each capsule delivers a standardized amount of olive-derived bioactive compounds, including oleocanthal and oleacein.
The comparator product is a matched placebo formulated from refined olive oil extract and is similar in appearance, taste, and packaging to the investigational product. The placebo is intended to serve as a control for study comparisons and does not contain the standardized olive-derived bioactive compounds present in the investigational product.
