Review: Life Changing? - I'm a long-perm consumer of anti-depressant and anti-enxiety meds. This Thorne product appears to have have given me the boost that prescription meds cannot match. Such has been the positive change in the six weeks since I began taking it, I am reluctant to put it all down to Quercetin, but I haven't had a single bad day since starting them. Before this, I rarely had a good day. I will update in a few months.

## Questions & Answers

**Q: How is this different then general quercetin?**
A: Thorne's Quercetin Phytosome utilizes the advanced technology of phytosome complexes. Phytosome complexes are created by a patented process that binds a designated botanical extract to a phospholipid. Phospholipids are readily absorbed key components of cell membranes, and when complexed with a botanical, the phospholipid increases the absorbability of the botanical to which it is combined. In Thorne’s Quercetin Phytosome, quercetin is combined with plant-based phospholipids to create a phytosome complex that significantly enhances the absorption of the quercetin through the cell membrane, compared to quercetin by itself.

**Q: What is the standardized quercetin phytosome content of thorne quercetin phytosome from flower extract?**
A: I emailed Thorne and this was their reply:

It is approximately 40% quercetin, so the product contains approximately 100mg of quercetin. Quercetin phytosome demonstrates 20x absorption vs standard quercetin in clinical studies.

**Q: Is the L-leucine derived from corn? Is this product free of corn?**
A: The leucine is derived from duck feathers, which are not pulled from the ducks but collected as they fall out.  None of Thorne’s finished products contain corn, however, occasionally a product might contain an ingredient derived from corn. These are purified and considered non-allergenic. The quercetin in Thorne's Quercetin Phytosome supplement is derived from Saphora japonica, which is a plant. The phospholipid complex is derived from sunflower.

**Q: What Color is the powder suppose to be?**
A: The powder in the capsules of Thorne’s Quercetin Phytosome can vary in color from pale yellow to orange, and can sometimes have a speckled or slightly mottled appearance.
