Product Description
Dihydroquercetin (taxifolin) from larch wood is a flavanonol, typically 90%, 95% or 98%. It is not quercetin, even though the names are close.
It is used as an antioxidant in capsules and in some food-antioxidant and cosmetic systems, and as a high-purity reference. The larch source matters for the residual-wood and solvent story.
When buying, use both names on the PO so a quercetin lot cannot be substituted, and set the assay.

Antioxidant Blends
Name taxifolin or dihydroquercetin on the label so it is not read as quercetin.
Pale Grades
98% tints less than 90%. Ask for the colour if the drink is clear.
