How is quercetin dihydrate from Japanese pagoda tree different from ordinary quercetin? — Quercetin VEGE, 90 Capsules – OstroVit

Quercetin is a flavonoid found in many plants: onions, apples, tea, berries. In supplements, though, it can differ in form and raw-material source, and that affects exactly what you get in a capsule.

OstroVit Quercetin VEGE uses quercetin dihydrate — a form in which the quercetin molecule is bound to two water molecules. This is a standard pharmacopoeial form used in making food supplements. The source is Sophora japonica L. (Japanese pagoda tree), whose fruit contains a high concentration of flavonoids and has long been used as a plant raw material for obtaining them.

For the buyer this means several practical things:

• A clear origin: the active component is obtained from a specific plant source rather than being a synthetic analogue.
• One key ingredient: the formula is not overloaded with extra flavonoids or plant extracts — you get quercetin itself, without complex combinations.
• Vegan status: the capsules are plant-based, which matters for anyone avoiding ingredients of animal origin.

If you are already taking other antioxidants or flavonoids, consult a specialist before adding quercetin to your diet — especially if you are taking medication.
