Taxifolin, also known as Dihydroquercetin, is a naturally occurring flavonoid belonging to the flavanonol class.
It is found in various plants, including Siberian larch (Larix sibirica), Douglas fir, milk thistle, and onions.
Taxifolin is structurally similar to quercetin but lacks the C2=C3 double bond, which significantly enhances its stability and antioxidant capacity.
As a potent antioxidant, taxifolin has demonstrated strong free radical scavenging activity, metal chelation, and inhibition of lipid peroxidation.
Its stability and bioavailability make it a valuable ingredient in dietary supplements, functional foods, and cosmetic formulations.
Taxifolin also exhibits anti-inflammatory, cardioprotective, and hepatoprotective properties.
Taxifolin is available in three purity grades (90%, 95%, and 98%) to meet different formulation and cost requirements.
Taxifolin
Antioxidant activity: Scavenges free radicals and chelates metal ions.
Anti-inflammatory support: Modulates inflammatory pathways (NF-κB, COX-2).
Cardiovascular health: Supports vascular function and reduces oxidative stress.
Hepatoprotective effects: Protects liver cells from oxidative damage.
Skin health: Used in anti-aging and photoprotective cosmetic formulations.
Stability: More stable than quercetin, with better formulation compatibility.
Source: Siberian larch (Larix sibirica) wood extract
