I bought this a couple of times this year for $18/bottle, and now the price is up to $32. Any explanation?

I too was purchasing at around $18/bottle and now it's gone up, not to $32 but $24 which is still a 35% increase. I understand things go up and down but that's quite a difference... I will be looking at other sources.

Which form of querceten is this product? ( dihydrate, glycosides, aglycone, or rutinoside?)

I spoke to Jarrow, per their rep it is anhydrous form. So it is about 10% more quercetin per gram than dihydrate because two H2O molecules have been removed.

What is the source of the quercetin?

I inquired about this in December and this is Jarrow's response: "Jarrow Quercetin is sourced from the Japonica Sophora Tree, and is the anhydrous form."
