For decades, Russian researchers called it Дигидрокверцетин — a powerful natural flavonoid drawn from the heartwood of Siberian and Daurian larch. In the West it is better known as Dihydroquercetin (DHQ) or Taxifolin. Today it is one of the most sought-after plant antioxidants for nutraceuticals, cosmetics and functional food. This guide covers everything global B2B buyers in Russia, Europe and North America need to know to source responsibly, formulate safely, and capitalize on its fast-growing demand.

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.

🔎 Search note: Shoppers rarely agree on the name. In Russia the molecule is almost always searched in Cyrillic — «дигидрокверцетин» or «таксифолин купить» — while buyers across Europe and North America more often type «dihydroquercetin powder» or «taxifolin 99% bulk». A page that uses both spellings (and names the larch source) surfaces for every variant of the query.

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.

GradeAssay (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
⚖️ Why 98% / 99%? At 98%+ the impurity profile is minimized and the HPLC chromatogram is clean — essential for brands that print “Dihydroquercetin 98%” or “Таксифолин 99%” on the label and must defend it with a CoA.

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

8.Industrial Applications

SegmentFormatNotes

Functional Food & BeveragePowder blends, sticksNatural antioxidant & preservative
Cosmetics & SkincareSerums, creamsAnti-aging, brightening, protective
Sports NutritionRecovery blendsOxidative-stress management
Pharma & Research99% reference materialClinical & 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.
  • Format note: Slightly bitter, water-soluble powders blend well into sticks, capsules and beverage mixes.
  • Stability: Store sealed at ≤ 25 °C, away from light and moisture.

10.Safety & Quality Control

Every batch ships with a full Certificate of Analysis: HPLC assay, heavy-metal panel (ICP-MS), microbial limits and solvent-residue report. Our Taxifolin is produced under HACCP/GMP-aligned controls with full traceability to the larch raw material.

⚠️ Responsible labeling: In Russia, Дигидрокверцетин products commonly carry precautions for pregnancy, lactation and children under 12. Always follow the regulatory framework of your target market.

12.Frequently Asked Questions (FAQ)

Q: Is Taxifolin the same as Dihydroquercetin?
A: Yes. Taxifolin and Dihydroquercetin (DHQ) are two names for the same molecule (CAS 480-18-2). Russian labels use Дигидрокверцетин; Western labels use either term.
Q: What is the difference between 98% and 99%?
A: Both are HPLC-validated premium grades. 99% offers the lowest impurity profile for pharma/research; 98% is ideal for high-end supplements and cosmetics at a better value.
Q: Where is your Taxifolin sourced from?
A: From larch (Larix spp.) wood — Siberian/Daurian larch for the Russian-market profile, with full botanical traceability.
Q: Do you ship to Russia, Europe and the USA?
A: Yes. We regularly export to all three regions with the correct documentation for each destination.
Q: Can I get a Certificate of Analysis before ordering?
A: Absolutely — a current CoA, MSDS and HPLC chromatogram are available on request before any commitment.

13.Conclusion

The most successful Taxifolin launches in 2026 share three traits: (1) a clearly stated purity grade (98% or 99%), (2) verifiable HPLC documentation, and (3) correct regional labeling — Дигидрокверцетин in Russia, Dihydroquercetin / Taxifolin in the EU and USA. Get those right and you capture demand across all three markets.

Looking for a Reliable Taxifolin 98% / 99% Supplier?

Whether you need bulk Dihydroquercetin for Russian-market capsules, EU food-grade powder, or US 99% reference material — always verify with a full HPLC CoA, heavy-metal panel and solvent-residue report before committing.
