Eubio Isoquercetin

Eubio Isoquercetin is a proprietary water-soluble formulation of **isoquercetin** developed by ALPS Pharmaceutical that is designed to improve the poor aqueous solubility and oral absorption of conventional isoquercetin. Isoquercetin is a naturally occurring flavonoid glycoside derived from *Sophora japonica* and has been studied as a small-molecule inhibitor of **protein disulfide isomerase**, a mechanism proposed to reduce thrombosis risk and potentially modulate thromboinflammatory pathways. The Eubio formulation uses all-natural food ingredients and reportedly achieves substantially higher quercetin exposure than ordinary isoquercetin without enzymatic modification, enabling lower doses versus standard isoquercetin preparations. The product appears to sit at the boundary between a drug-like nutraceutical and dietary supplement ingredient rather than a clearly approved pharmaceutical medicine.
