Biogena Quercetin Phytoactive Gold

The secret of Quercetin Phytoactive Gold lies in an Italian raw material and its very special production method: The valuable flavonoid is not present here in free form but is encased in sunflower phospholipids. This proprietary technological innovation on plant basis enables the contained quercetin to be absorbed particularly well by our body. The optimal bioavailability of quercetin in this form was shown in a clinical study. The basis of the unique raw material is the most popular source of quercetin, the Japanese cord tree (Sophora japonica).
