Study of Wild Blueberry Powder Effects on Gut Health, Inflammation, and Joint Pain in Adults Aged 40 to 75

What this Trial Is About

Researchers are studying how dietary wild blueberries affect gut microbiome, inflammation markers in the blood, and joint function in adults with arthritis. The study aims to better understand the potential relationship between blueberry consumption and joint health. This is a randomized, double-blind trial sponsored by the University of Nevada, Las Vegas, focusing on adults aged 40 to 75 years with multi-joint or knee arthritis. Participants will be randomly assigned to consume either 25 grams of freeze-dried wild blueberry powder or a placebo powder without polyphenols but matched for calories daily for 12 weeks. There is a 2-week washout phase between treatment periods. The study involves two groups one taking the blueberry supplement and the other taking the matched placebo. During the study, participants will have their joint function assessed through blood tests measuring serum biomarkers after 12 weeks. Researchers will also analyze changes in the gut microbiome. The study includes monitoring for signs of inflammation and joint pain. Participants will attend scheduled visits for assessments throughout the trial, which lasts approximately three months.
