Stronger Defences
Rosehip has long been used in traditional medicine to help prevent colds and infections - now supported by modern research. Its antioxidants help strengthen immune defences and may reduce the duration of respiratory infections (Mármol et al., 2017).
Among its polyphenols, quercetin stands out for its antiviral and anti-inflammatory effects. It helps block viral entry and replication, modulates inflammatory responses, and provides antibacterial support (Chen et al., 2006; Rojas et al., 2016; Uchide & Toyoda, 2011; Wang et al., 2016).
Notably, quercetin, especially combined with vitamin C, has been shown to shorten the duration of colds and support immune resilience (Biancatelli et al., 2020; Kinker et al., 2014).
