Hops Extract May Provide Joint Health Benefits
Hops are the flower of the hop plant and are widely used to flavor beer. A new study suggests that supplementation with hops extract may provide joint health benefits.
For their study, the researchers enrolled 36 adults with an average age of 57 years. All had been diagnosed with osteoarthritis of the knee. They received 1 gram of standardized hops extract, 2 grams of standardized hops extract, or a placebo daily for 14 days.
Perceived pain was evaluated at baseline and at the end of the study period using the Western Ontario and McMaster Universities Osteoarthritis Index. Participants’ performance in a 20-meter walking test was also evaluated at baseline and every day of the study period.
Participants in both hops groups saw significant reductions in discomfort while walking on a flat surface compared to the placebo group. Participants in the 2-gram hops group began to see reductions in discomfort on days 2 and 4. Participants in the 1-gram group began to see reductions in discomfort on days 2, 4, and 6.
Participants in the 1-gram hops group saw the greatest improvements in discomfort while sitting or lying in bed at the end of the study. Participants in the 2-gram hops group saw greater improvements in discomfort while sitting or lying in bed compared to the placebo group.
The study was conducted by researchers from Lindenwood University. It was published online ahead of print on July 28, 2022 in the Austin Journal of Nutrition & Metabolism.
Curcumin was found to help relieve knee joint discomfort in a previous study.
