Introduction to Dihydroquercetin (DHQ / Taxifolin)
Dihydroquercetin (DHQ), also known as taxifolin, is a naturally occurring bioflavonoid derived from various plant sources, including Siberian larch (Larix sibirica) and Douglas fir (Pseudotsuga menziesii). As a potent antioxidant, DHQ exhibits exceptional free radical scavenging activity, often surpassing that of other well-known flavonoids like quercetin.
Unlike synthetic antioxidants, dihydroquercetin offers high bioavailability and low toxicity, with no reported embryotoxicity, teratogenicity, or allergenicity. Its stable molecular structure makes it an ideal choice for nutraceutical, pharmaceutical, and food preservation applications.
Botanical Essence specializes in high-purity dihydroquercetin extract, ensuring consistent quality, traceability, and compliance with international standards for dietary supplements, functional foods, and industrial formulations.
