A new study from Baghdad’s Al-Rafidain University College found that osteoarthritis patients who were administered resveratrol, an antioxidant found in red grape skin, reported reduced pain and inflammation in their knees.

The study, published online in the Journal of Medicinal Food on Aug. 30, 2018, is the first to examine the effects of the compound on knee osteoarthritis patients, the Spectator reports.

Following 110 knee osteoarthritis patients over a three-month period, half were given a 500mg dose of resveratrol each day, while the other half received a placebo. Both were taken in conjunction with NSAIDs (non-steroidal anti-inflammatory drugs, like Ibuprofen).

Patients who took resveratrol reported lower pain scores, as well as significant reduction in inflammation, the latter measured via biomarkers from blood tests.

Other reported benefits of resveratrol include longer fertility, weight loss, and staving off aging. Go ahead and grab a glass, and enjoy responsibly.
