Flavonoid Defense Domain™
BioQin™ — Dihydroquercetin (Taxifolin)
BioQin™ is a high-purity dihydroquercetin (taxifolin) concentrated from the protective chemistry of the Dahurian larch (Larix gmelinii). In the tree, this flavonoid helps manage oxidative stress, environmental damage, and metabolic strain in one of the harshest forest ecosystems on Earth. In formulations, BioQin™ functions as a high-activity antioxidant system designed for nutraceuticals, functional foods, advanced animal nutrition, and dermal applications.
Overview
Flavonoid Defense from Dahurian Larch. BioQin™ delivers high-efficacy antioxidant capacity for redox balance and formulation stability, and serves as the lead representative of the Flavonoid Defense Domain™ in the Dahurian Bioactives platform.

Functional Profile — Flavonoid Defense for Redox and Stability
High-Efficacy Antioxidant Activity
BioQin™ exhibits very high hydrophilic ORAC values (≈ 32,700 µmol TE/g), translating into:
- strong radical-scavenging capacity
- robust support for redox homeostasis
- protection of vulnerable biomolecules and formulation components
Redox Modulation & Cellular Protection
- buffers oxidative stress by neutralizing reactive oxygen species
- supports maintenance of endogenous antioxidant systems
- helps protect membrane lipids and structural proteins from oxidation
Context: These effects support cellular “defense readiness” where oxidative load is elevated.
Microcirculation & Vascular Support
Mechanistic literature on dihydroquercetin indicates:
- support for capillary and microvascular integrity
- favorable effects on endothelial function and blood rheology
- antioxidant protection along the vascular wall
Positioning note: BioQin™ is not positioned as a drug; these findings support use in formulas targeting vascular, metabolic, and performance concepts where oxidative stress and microcirculation are relevant.
Gut–Liver–Metabolic Axis Support
- may help mitigate oxidative load in hepatic and intestinal tissues
- supports detoxification processes that rely on balanced redox states
- can complement SCFA- and fiber-mediated effects of arabinogalactan in dual-domain systems
Synergy with Structural Fiber Domain™
- the fiber matrix helps distribute and maintain dihydroquercetin throughout the system
- dihydroquercetin helps protect the overall matrix and co-actives from oxidative depletion
Design pathway: This is the basis of your Synergy Premix (1:3 and 1:5) concept — referenced here, and expandable on the Synergy page.
Formulation Behavior & Delivery
Solubility & Carriers
DHQ is moderately soluble in water; dispersibility and delivery can be enhanced via:
- suitable carriers (e.g., polyols, cyclodextrins, or fiber matrices)
- granulation or encapsulation technologies
- custom formats to improve dispersibility or target specific applications
Color & Sensory Profile
- light yellow hue typical of flavonoids; manageable in most solid and capsule formats
- mild taste impact at typical use levels; easily masked in flavored powders or functional foods
Stability
- good stability in dry form when protected from light, oxygen, and excessive heat
- finished-product stability is enhanced by pairing with structural fiber (BioGala™) and using appropriate carriers and packaging
Origin & Sustainability
BioQin™ is derived from the same winter-harvested Dahurian larch biomass as BioGala™ — a renewable forestry by-product processed with respect for ecosystem cycles. No trees are harvested solely for extraction.
- a unified sustainability story across fiber and flavonoid ingredients
- aligned traceability and documentation
- a coherent dual-domain platform for customers building multi-ingredient systems
