In June 2018 researchers from Iran and Australia published the results of their study to assess the effect of garlic supplementation on knee osteoarthritis in overweight or obese women. A total of 76 postmenopausal overweight or obese women with knee osteoarthritis were involved in the study. The degree of osteoarthritis was assessed, including levels of pain, stiffness and mobility, both before and after the study. The individuals were divided into two groups and received a daily dose of either 1000 mg odourless garlic tablet, or placebo for a period of 12 weeks. Results showed that pain, stiffness and mobility all improved significantly following the garlic supplementation. The level of stiffness was significantly lower in the garlic group when compared to the placebo group, but not the pain or mobility. However, it was also noted that the level of pain was also reduced in the placebo group.
