Absorption & Bioavailability
When it comes to Quercetin supplementation, form selection is one of the most consequential decisions you can make. Different chemical forms of Quercetin vary significantly in how well your body absorbs and uses them — and Quercefit Phytosome vs Quercetin Dihydrate is one of the most commonly compared pairs.
Quercefit Phytosome has a higher bioavailability tier (high (S1 — best tier)) compared to Quercetin Dihydrate (moderate (S3)), meaning more of the active compound reaches the bloodstream per dose unit.
Quercefit Phytosome carries a bioavailability tier of S1 (high (S1 — best tier)) and is classified as T1 Preferred in the FormulaForge formulary. Quercetin Dihydrate carries a bioavailability tier of S3 (moderate (S3)) and is classified as T3 Customer Choice.
Quercefit uses a phospholipid phytosome complex to achieve 20x greater bioavailability than standard quercetin dihydrate. The phytosome technology enables reliable plasma levels at practical doses, supporting antioxidant, anti-inflammatory, and immune responses that standard quercetin cannot match at typical supplement doses.
