EubioQuercetin
EubioFlavonoid® delivery technology allows EubioQuercetin to have excellent water solubility. It leads to significant enhancement of oral absorption of the active flavonoids ( Highly absorbable Qurecetin ) based on rutin*. EubioQuercetin is produced only with safe ingredients and additives. This product is very different from artificial flavonoids that have been enzymatically or chemically modified.
*Rutin is quercetin-3-O-rutinoside.
Water Solubility of EubioQuercetin
The bar chart shown in Fig 1 allows to compare the water-solubility difference between EubioQuercetin and rutin.
Since EubioQuercetin is at least 240,000 times more water soluble compared to quercetin, it is expected to have wide application, including in cosmetic, beverage, food, supplement, and pharmaceutical industries.
