Forms of EubioQuercetin® Compared

EubioQuercetin® (Customer Choice) has a bioavailability rating of high (S1 — best tier). Typical dose range: not yet documented in our database.

What the Research Shows

Quercetin aglycone bioavailability is exceptionally poor. Human RCT established 20x enhancement for lecithin phytosome (Quercefit). A 2025 meta-analysis of 31 human studies confirms this range, with advanced formulations reaching up to 62x enhancement.

Quercetin phytosome (Quercefit) demonstrated 20-fold higher plasma quercetin AUC compared to unformulated quercetin in a human crossover RCT. PMID: 30328058

2025 meta-analysis of 31 human quercetin studies confirms formulated versions achieve 20-62x bioavailability enhancement over standard aglycone. PMID: 40037045

Quercetin aglycone undergoes extensive phase II metabolism, resulting in less than 2% oral bioavailability, establishing the need for advanced delivery systems. PMID: 34194240
