Is this trial a fit for you?

Likely a good fit

Ideal candidates are English-speaking adults aged 40–75 with self-reported knee discomfort for at least three months who can take a daily capsule, complete digital questionnaires and at-home functional tests, and use a compatible activity tracker.

Probably not a fit

People with diagnosed inflammatory joint diseases, a prior diagnosis of knee disease, recent or significant knee surgery, or other systemic conditions affecting the knee are unlikely to benefit from this intervention.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, double-blind, placebo-controlled study gives adults with at least three months of knee discomfort one capsule daily of either an olive oil extract or a matched placebo for six weeks. Participants complete baseline and follow-up digital questionnaires about knee pain, stiffness, and function, perform two self-administered functional movement tests (Stair Climb Test and Timed Up and Go), and record any pain medication use or side effects. Optional wearable data on sleep and activity and home-collected saliva samples will provide supportive real-world and exploratory measures. The trial is conducted through the Alethios platform with remote consent and at-home procedures to minimize participant burden.

Why it matters

Potential benefit: If successful, daily olive oil extract could reduce knee discomfort and improve day-to-day knee function for adults with chronic knee pain.

How similar studies have gone: Some small clinical and preclinical studies of olive oil polyphenols and related extracts suggest potential benefits for joint comfort and inflammation, but large, definitive trials are limited.
