In addition to the STEP trials, real-world studies and independent reviews further support the effectiveness of a variety of GLP-1 receptor agonists for weight management, with weight loss typically ranging from 5% to 15% depending on dose, duration, and adherence.28,29 A retrospective, noninterventional drug utilization cohort study in the United Kingdom evaluated the use of different varieties of liraglutide for weight management purposes.30 Among 604 individuals using Saxenda (liraglutide 3 g) and 4,853 individuals using Victoza (liraglutide 1.2 mg/1.8 mg), most were able to achieve 5% weight loss within 24 weeks.30 Emerging data on tirzepatide has also shown even greater weight reductions (up to 21% over 72 weeks) over other GLP-1s, as well as improved quality of life.31,32 Together, these findings show the support GLP-1s can provide in long-term weight management

Quercetin was demonstrated to inhibit ferroptosis and improve joint cartilage destruction and degradation, delaying OA progression, by activating the AMP-activated protein kinase (AMPK)/Nrf2/GPX4 signaling pathway (Dong et al., 2025)
