If you are exploring high-potency antioxidant supplements, you may have encountered the branded ingredient Lavitol® DHQ. At its core, Lavitol DHQ consists of Dihydroquercetin (DHQ) – a premium-grade, plant-based flavonoid also known as Taxifolin. Renowned for its potent free-radical neutralizing capacity, this compound is scientifically recognized for supporting cellular health and resilience.

Kintaibio® specializes in the production of high-purity dihydroquercetin, sourced directly from larch tree extract. We offer the same molecular quality and bioactive benefits associated with the Lavitol DHQ brand-but through a more cost-effective and direct supply chain.
Lavitol and DHQ
Lavitol® DHQ is a recognized standardized ingredient brand in the nutritional supplement and functional food industry. Its core value stems from its high-purity active ingredient-Dihydroquercetin, also known as Taxifolin. This is a natural flavonoid compound extracted from the Russian larch tree using advanced technology. Its chemical structure is well-defined; it is not a mixture of plant extracts, but a single molecule with highly consistent and bioactive properties.

For end consumers, choosing products containing Lavitol DHQ means choosing an antioxidant ingredient that has undergone rigorous standardization in purity and efficacy. Its core function is to help the body resist oxidative stress, protect cells from free radical damage, and thus support cardiovascular health, microcirculation function, and overall health maintenance.
For B2B buyers and brand owners, Lavitol DHQ represents more than just an ingredient name; it represents a reliable quality benchmark. The brand ensures that its DHQ purity is typically above 90% through strict production control. This provides clear dosage guidelines and stable efficacy expectations for product formulation, greatly simplifying product development and quality control processes. It's worth emphasizing that while Lavitol has established strong brand recognition in the market, the true driver of its product efficacy is the Dihydroquercetin molecule itself. Therefore, the key to sourcing and branding decisions lies in ensuring that raw materials meet or exceed Lavitol's purity specifications.
Our Dihydroquercetin Powder is precisely such a high-quality raw material, maintaining a purity consistently above 98%. This ensures you can obtain the same core efficacy as well-known brand ingredients in a more cost-effective way, thereby creating a highly competitive end product in the antioxidant niche market.

The Lavitol DHQ Source: Siberian Larch Extract Taxifolin
Siberian larch is a superior natural source of high-purity dihydroquercetin (DHQ), with its bark containing up to 11.80% DHQ, far exceeding other tree species. It has become an important raw material for the global health supplement, pharmaceutical, and cosmetic industries. To ensure the purity and safety of DHQ, Lavitol DHQ manufacturers implement strict control from raw materials to finished products:

For raw materials, Lavitol® DHQ is extracted from Dahurian larch (scientific name: Larix gmelinii), a tree species mainly distributed in Siberia and the Russian Far East (such as Amur Oblast). These areas are generally considered to be places with pristine ecosystems. The raw materials used in the production of Lavitol® DHQ primarily come from tree stumps left after logging. This practice is equivalent to adding value to forestry by-products and has a certain degree of sustainability.
In production, they employ water-ethanol combined extraction and ultrasonic-assisted technology, achieving an extraction rate of up to 36.76 mg/g under optimized conditions. Further purification through resin chromatography and multi-step crystallization increases the final purity to over 90%, meeting pharmaceutical-grade standards for use in the pharmaceutical and dietary supplement markets.
The finished product's quality is verified using multiple technologies, including HPLC.
Currently, DHQ from this source undergoes full-process parameter control from raw material collection and extraction parameter monitoring to finished product drying, ensuring batch-to-batch consistency. It has obtained FDA GRAS certification in the United States, EFSA approval in the European Union, and complies with international system standards such as GMP, ISO9001, and ISO22000, ensuring its global applicability and food safety.
Advantages of Lavitol® DHQ

Powerful Antioxidant Activity
Lavitol® DHQ Has Been Shown To Have A Very High Oxygen Radical Uptake Capacity (ORAC) Value, Exceeding The Antioxidant Capacity Of Some Known Antioxidants. As A Powerful Natural Antioxidant, It Helps Protect Cells From Free Radical Damage.
Excellent Safety Certification
Its safety is supported by numerous toxicological studies, including genotoxicity, subacute and subchronic toxicity tests, all of which support its safety as a food supplement and food additive. Furthermore, it is approved for use as an active pharmaceutical ingredient or food supplement in Russia and the European Union.
Optimization of Bioavailability
Natural dihydroquercetin suffers from poor water solubility, which may limit its absorption and application. However, its water solubility can be significantly improved through "green" processing technologies such as lyophilization (studies show an improvement of at least 30 times). Studies have also explored combining it with L-lysine to improve solubility. Lavitol® DHQ itself employs a standardized extraction process designed to ensure its bioactivity and absorption.
Broad Application Potential
Based on its antioxidant properties, Lavitol® DHQ has applications in dietary supplements, the food industry (such as in cream, chocolate, and milk powder as an antioxidant), and cosmetics. Studies suggest potential benefits in supporting cardiovascular, immune, and liver health.
While Lavitol® DHQ shows promise, careful attention must be paid to the actual formulation and solubility in practical applications. Although technologies such as lyophilization can improve the water solubility of dihydroquercetin, it is still necessary to check the specific technologies used to ensure the dissolution and absorption of the active ingredient when purchasing related products. Furthermore, dosage safety should be considered; according to Russian recommendations, the daily intake of dihydroquercetin is between 25 mg and 100 mg.
