Supplement Containing Multiple Polyphenols May Support Joint Health
Polyphenols are compounds found in fruits and vegetables that give them their vibrant colors. They have strong antioxidant and anti-inflammatory properties. A new study suggests that supplementation with polyphenols from multiple sources may help support joint health.
Participants in the study included 25 adults who were experiencing issues with their knee joints. Half were given a supplement containing 148.4 mg of curcuma phospholipids, 51.9 mg of rosemary extract, and 51.9 mg of resveratrol extract daily for 3 months. The other half were given a placebo.
The researchers used the Visual Analog Scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis (WOMAC) pain subscale to evaluate joint discomfort at baseline and at the end of the study period. They also measured joint stiffness and functionality at baseline and at the end of the study period.
Participants in the supplement group saw a significant decrease in the overall WOMAC score, compared to no change in the placebo group. They also saw greater decreases in the WOMAC discomfort score compared to the placebo group. No changes were seen in stiffness or functionality.
The study was conducted by researchers from Harokopio University,. It was published in the 2022 edition of the journal Dietetics.
Hops extract was found to support joint health in a previous study.
