Daily resveratrol supplementation at 500mg for 18 weeks significantly improved balance, gait speed, and knee range of motion in 129 osteoarthritis patients, while increasing plasma SIRT1 levels by mechanisms that correlated strongly with balance improvements (r²=0.322). The longevity protein SIRT1 emerged as a key mediator, suggesting resveratrol's balance benefits extend beyond simple anti-inflammatory effects. This finding addresses a critical gap in osteoarthritis management, where postural instability dramatically increases fall risk—a leading cause of injury-related death in older adults. The SIRT1 connection is particularly intriguing because this longevity pathway regulates cellular stress responses, mitochondrial function, and potentially proprioceptive signaling that governs balance. While promising, the study's 18-week duration leaves questions about long-term efficacy and optimal dosing unanswered. The research represents incremental but meaningful progress, offering osteoarthritis patients a natural intervention that targets both joint symptoms and the dangerous secondary consequence of balance impairment. However, larger studies with longer follow-up periods are needed to establish resveratrol's role in preventing falls and fractures in this vulnerable population.
