1.What Is Taxifolin (Dihydroquercetin)?
Taxifolin — also called Dihydroquercetin (DHQ) or simply Дигидрокверцетин / Таксифолин in Russian-speaking markets — is a natural flavonoid (specifically a flavanonol) belonging to the same family as quercetin. The key structural difference: the C2–C3 double bond of quercetin is saturated in taxifolin. That single hydrogenation step makes taxifolin markedly more stable in water, heat and light, while retaining exceptional free-radical scavenging power.
2.Botanical Source & Origin
Commercial Taxifolin is extracted from the wood and bark of larch trees (Larix spp.), most importantly:
- Siberian larch (Larix sibirica) — the traditional, high-yield Russian source.
- Daurian larch (Larix gmelinii) — widely used across the Russian Far East.
- European larch (Larix decidua) — relevant for EU-sourced material.
The molecule also occurs in trace amounts in milk thistle, French maritime pine and citrus, but larch wood remains the only economically viable bulk source — which is why “Siberian larch taxifolin” is the dominant quality signal in B2B procurement. Russian brands lean heavily on Siberian and Daurian larch, while European and North American formulators increasingly ask for traceable, sustainably harvested larch — so naming the exact botanical origin on the spec sheet prevents costly back-and-forth later.

4.98% vs 99% — Purity Grades
We supply Taxifolin at two premium concentrations. Both are validated by HPLC; the choice depends on your finished-product positioning.
| Grade | Assay (HPLC) | Typical Application |
|---|---|---|
| Taxifolin 90% | ≥ 90.0% | Food & beverage antioxidant, industrial use |
| Taxifolin 95% | ≥ 95.0% | Standard nutraceutical blends |
| Taxifolin 98% | ≥ 98.0% | Premium supplements, cosmetics, capsules |
| Taxifolin 99% | ≥ 99.0% | Pharma research, high-end & clinical formulations |
5.Antioxidant Mechanism of Action
Taxifolin's value comes from a multi-pathway mechanism rather than a single trick:
- 🔥 Free-radical scavenging — donates phenolic hydrogens to neutralize ROS and RNS.
- 🛡️ Metal chelation — binds Fe²⁺/Cu²⁺ to suppress Fenton reactions.
- 🩸 Capillary & vessel support — strengthens vascular endothelium and microcirculation.
- 🌿 Anti-inflammatory modulation — helps down-regulate oxidative stress pathways.
Because the molecule is more chemically stable than quercetin, it survives formulation, stomach acid and shelf storage far better — a decisive advantage for supplement and cosmetic brands.
6.Evidence-Based Benefits
Cardiovascular & Capillary Health
Supports healthy blood vessels, microcirculation and capillary resilience — the core claim behind long-established Russian Дигидрокверцетин supplements and a fast-growing heart-health category for EU and US brands.
Evidence: Strong (traditional + preclinical)Skin & Anti-Aging (Cosmetics)
Potent antioxidant for serums and creams — a favorite of European and North American clean-beauty formulators for UV- and pollution-induced oxidative stress.
Evidence: Strong (topical)Immune & Seasonal Support
A winter staple in Russian wellness routines for seasonal respiratory support, and an everyday antioxidant defense increasingly folded into Western immune blends.
Evidence: ModerateSports Recovery & Endurance
Reduces exercise-induced oxidative damage; popular in recovery and longevity stacks.
Evidence: EmergingLiver & Detox Support
Hepatoprotective activity noted in preclinical models; used in detox formulations.
Evidence: Moderate (preclinical)Diabetic & Metabolic Wellness
Studied for antioxidant support of metabolic health and capillary protection in diabetics.

8.Industrial Applications
| Segment | Format | Notes |
|---|---|---|
| Dietary Supplements | Capsules, tablets, powders | 25–100 mg/day typical; solo or with Vitamin C |
| Functional Food & Beverage | Powder blends, sticks | Natural antioxidant & preservative |
| Cosmetics & Skincare | Serums, creams | Anti-aging, brightening, protective |
| Sports Nutrition | Recovery blends | Oxidative-stress management |
| Pharma & Research | 99% reference material | Clinical & lab use |
In practice the ingredient shows up a little differently by region: 25–100 mg capsules dominate the Russian shelf, EU brands favor food-grade blends and sticks, and US laboratories plus premium supplement houses drive most of the demand for 99% reference-grade material. The spec sheet and label claims should flex accordingly — without ever changing the underlying molecule.
9.Recommended Dosage & Formulation
- Typical daily dose: 25–100 mg of Dihydroquercetin, often split into two servings with meals.
- Synergy: Frequently paired with Vitamin C for enhanced antioxidant effect.
