Thorne Research, Quercetin Phytosome, 60 Capsules

The crucial advantage that is attributable to Quercetin Phytosome is its advanced phytosome technology. Phytosome complexes are created by a patented process that binds a botanical extract to phosphatidylcholine, a key component of cell membranes. In the case of Quercetin Phytosome, quercetin is combined with sunflower-sourced phosphatidylcholine to create a phytosome complex that easily crosses the gut barrier.*
