What is Dihydroquercetin (Taxifolin)?

The world's most potent natural antioxidant

The antioxidative activity of dihydroquercetin or taxifolin far exceeds that of more common antioxidants such as tocopherols (vitamin E), ascorbic acid (vitamin C), or other flavonoids.

Dihydroquercetin, or taxifolin as it is known in medicine, is a compound present in many plant species, but it is found in the highest concentrations in the wood of the Siberian and Dahurian Larch trees which grow abundantly in the northeast of Russia.

Dihydroquercetin, or taxifolin, belongs to the flavanone class of flavonoids. It has two primary effects in humans, it is an extremely potent antioxidant and it has powerful protective effects for the cardiovascular and immune systems, amongst other health promoting properties.

PROPERTIES OF DIHYDROQUERCETIN

Dihydroquercetin or taxifolin is one of the most potent natural antioxidants in the world. The antioxidative activity of dihydroquercetin or taxifolin far exceeds that of more common antioxidants such as tocopherols (vitamin E) and ascorbic acid (vitamin C).

For comparison purposes, the table below presents the antioxidant capacities dihydroquercetin as well as of some other well-known natural antioxidants.

Substance ORAC 5.0 Value
Dihydroquercetin 99.6% purity 104,000 μM TE/g
Dihydroquercetin 98% purity 64,200 μM TE/g
Dihydroquercetin 95-96% purity 32,744 μM TE/g
Dihydroquercetin 92-93% purity 21,940 μM TE/g
Dihydroquercetin 88-90% purity 15,155 μM TE/g
Luteolin 12,100 μM TE/g
Quercetin 10,900 μM TE/g
Vitamin C 2,100 μM TE/g
Vitamin E 1,300 μM TE/g

Research shows that dihydroquercetin or taxifolin offers significant protection from free radicals, which helps to inhibit lipid peroxidation and promotes key detoxification processes, while guarding against the depletion of key antioxidants like glutathione, vitamin A (retinol), vitamin C, and vitamin E.

Dihydroquercetin increases the shelf-life of many common foodstuffs, and its antioxidant properties make it an ideal value added ingredient for the creation of healthy value added food products.. It is used in the meat, dairy, prepackaged food, as well as the fat and oil industries to prolong shelf life. It extends the shelf-life of drinks and juices, and is a beneficial additive to alcoholic beverages. Additionally it has multiple applications in the cosmetics industry.

Several companies produce dihydroquercetin. Most of them manufacture dihydroquercetin with a purity of 70% - 80%; 90%, 92% or up to 94%. Only two Russian companies, Flavit and Taxifolia, with their innovative and patented technologies are able to produce dihydroquercetin from the Siberian or Dahurian Larch trees at over 94% purity and, only one can produce dihydroquercetin with purity 98% and higher to 99.6% in quantities and appropriate price point so that it can be used in the pharmaceutical and cosmetics industry.

High quality dihydroquercetin extraction is a slow and very subtle manufacturing process, which does not use high temperatures. Increasing the purity of dihydroquercetin significantly increases production costs, but as can be seen above, an increased purity results in a significantly higher effectiveness of the product. It appropriately is reflected by comparing ORAC scores of 90% of dihydroquercetin and 98% dihydroquercetin where the increased product purity results in quadruple the ORAC value. Accordingly, triples the price of the product.

If you find discrepancies between the ORAC values presented by us and others, please note that previous values have been determined using low purity (less than 85%) and perhaps highly polymerized forms of dihydroquercetin.
