Reported Mechanism (Provisional)

Mechanism of Action

Cuban guava's vitamin C enhances collagen synthesis through prolyl 4-hydroxylase activation and supports immune function by promoting neutrophil chemotaxis. Quercetin and other flavonoids inhibit pro-inflammatory cytokines like TNF-α and IL-6 while activating antioxidant enzymes. The fruit's pectin content supports digestive health by promoting beneficial gut bacteria growth and improving intestinal barrier function.

Clinical Narrative (Provisional)

Limited human clinical trials exist specifically for Cuban guava, though studies on common guava show promising results. A 12-week study of 120 adults found guava leaf extract reduced systolic blood pressure by 8-10 mmHg. Small-scale studies (n=45-60) suggest guava consumption may improve antioxidant status and reduce inflammatory markers. Most evidence comes from in vitro and animal studies, indicating need for larger human trials.
