Dear Purchasing Managers and Importers
By 2050, nearly half of the world‘s population will be myopic, and 9.8% will suffer from high myopia. As the global prevalence of vision problems surges, are you stocking the right natural ingredients to meet rising consumer demand for eye health supplements?
Meet quercetin – a flavonoid “antioxidant star” that new research shows can alleviate myopia progression.
How Quercetin Protects the Retina
The retina relies on glycolysis for normal function, making it vulnerable to oxidative damage – a key driver of myopia. Studies reveal that during myopia progression, the AKT/FOXO/HK2 pathway becomes abnormally activated, inhibiting glycolysis and promoting retinal oxidative stress. Quercetin neutralizes reactive oxygen species, regulates NF-κB and MAPK signaling pathways, and reduces retinal cell apoptosis – slowing myopia advancement.
Beyond Eye Health: Multi‑Benefit Ingredient
Quercetin (GRAS certified by FDA since 2010, up to 500 mg per serving) offers a broad range of clinically supported benefits:
| Application | Key Findings |
| Anti-depression | Inhibits NLRP3 inflammasome, reduces neuroinflammation (animal model) |
| Obesity prevention | Activates AMPK-DAPK3-ULK1 axis, induces fat autophagy |
| Liver protection | Lowers ALT/AST, reduces inflammation & fibrosis in NAFLD |
| Anti-allergy | Inhibits IgE, regulates immune cells and histamine release |
| Immune support | Enhances cytokine secretion, reduces oxidative damage |
Quercetin Bioavailability – What Importers Must Know
Raw quercetin has low water solubility (0.01 mg/ml) and poor bioavailability (~2%). The market offers five main enhancement technologies. Justgood Health formulates quercetin into gummies, capsules, and soft gels using advanced delivery systems to improve absorption – ensuring your end products deliver real efficacy.
