Taxifolin Dihydroquercetin Powder
Products Description
Its active compound, dihydroquercetin, is a rare flavanol that is structurally similar to quercetin, but has higher bioavailability and stronger antioxidant capacity. It works by neutralizing free radicals, reducing oxidative stress, and supporting vascular and immune function. Compared with quercetin, dihydroquercetin is more water-soluble and more stable, making it ideal for formulation in dietary supplements, skin care products and functional foods.
Global demand for dihydroquercetin has grown steadily in recent years, especially in markets focused on natural anti-aging, cardiovascular health and clean label antioxidants. However, due to differences in raw material sources and extraction methods, the quality and purity of this ingredient may vary significantly between different suppliers.
At Botanical Cube Inc., we focus on providing dihydroquercetin powder with a purity of ≥98% (HPLC) and use advanced low-temperature extraction technology for batch-by-batch verification. Our products have a uniform and consistent off-white fine powder structure and good solubility, which can better meet various application requirements.
Why choose our Dihydroquercetin powder (Taxifolin, Siberian Larch Extract)?
Our product is extracted entirely from Siberian larch wood (Larix sibirica), and each batch is verified by HPLC (not UV) to contain ≥98.0% dihydroquercetin.
2. Low heavy metal content
Our tests show an average lead (Pb) content of <0.5ppm, arsenic (As) content of <0.2ppm, cadmium (Cd) content of <0.1ppm, and mercury (Hg) content below most global regulatory limits (including EU and USP standards).
3. Fine particle size for better dispersibility
Our powder is ground to D90 < 80μm, ensuring more uniform dispersion in capsule, tablet and beverage formulations without agglomeration or precipitation - a problem often overlooked by other bulk suppliers.
4. True Water Compatibility - No Sedimentation in Cold Water
Thanks to our low temperature processing methods and fine grade control, our powders have less than 5% sedimentation after 24 hours in cold water at pH 7, making them suitable for liquid and ready-to-drink products.
