Study Summary
This trial will study if a dietary supplement (PEA) can reduce pain in adults with knee osteoarthritis and determine how it works. It will look at protein signatures, inflammation markers & neurobiological pathways.
Who is the study for?
This trial is for adults aged 40-80 with self-reported knee osteoarthritis, who speak English and can consent to the study. Participants must not take any pain medication other than acetaminophen and should have a knee pain level of at least 4 out of 10. Those using opioids, pregnant or breastfeeding women, people with certain allergies or inflammatory arthritis, recent knee injuries or surgeries are excluded.Check my eligibility
What is being tested?
The study tests if taking PEA (a dietary supplement) for six weeks helps change protein signatures related to pain sensitivity in knee osteoarthritis patients. It's also checking if participants will stick to the regimen. Half will get PEA; the other half a placebo without knowing which one they're taking.See study design
What are the potential side effects?
Specific side effects aren't listed but as a dietary supplement, PEA could potentially cause digestive discomfort, allergic reactions based on its ingredients like oat or coconut oils, or interact with other medications.
