What is the Difference Between Quercetin and Quercetin Dihydrate?

🆚 Go to Comparative Table 🆚

Quercetin and quercetin dihydrate are both flavonoids with antioxidant properties, but they differ in their sources and chemical structures. The main differences between quercetin and quercetin dihydrate are:

  1. Source: Quercetin is a plant flavonoid found in fruits, vegetables, leaves, seeds, and grains, such as capers, radish leaves, red onion, and kale. Quercetin dihydrate, on the other hand, is a synthetic chemical compound.
  2. Chemical Structure: Quercetin dihydrate is a modified form of quercetin, where two additional atoms of hydrogen are added per molecule. This modification makes dihydroquercetin a more powerful antioxidant compared to quercetin.
  3. Solubility: Quercetin dihydrate is practically insoluble in water. In contrast, quercetin is soluble in alcohol, which contributes to the health-promoting effects of red wine.
  4. Bioavailability: Quercetin dihydrate has a low bioavailability due to its poor solubility in water. However, when quercetin is transformed into a water-soluble form, its absorption in the gastrointestinal tract and bioavailability are significantly improved.

Both quercetin and quercetin dihydrate are used in quercetin supplements, which are known for their anti-inflammatory and allergy symptom-relieving properties.
