Description
Quercetin Dihydrate is a naturally occurring flavonoid compound found abundantly in many fruits, vegetables, and plants, including onions, apples, berries, and tea leaves. Recognized for its antioxidant capacity, Quercetin Dihydrate is widely valued in the nutraceutical, food, and pharmaceutical industries. Unlike its anhydrous counterpart, the dihydrate form has two water molecules attached, contributing to improved stability and solubility in certain applications. As a dietary supplement ingredient, it is frequently included in formulations designed to support immune balance, circulatory health, and cellular defense against oxidative stress. Its long history of presence in human diets, combined with increasing scientific interest, has positioned Quercetin Dihydrate as one of the most versatile plant-derived bioactive compounds.
Nutritional Profile
Quercetin Dihydrate is not a vitamin or mineral but a polyphenolic flavonoid categorized within the flavonol subclass. While it is not considered an essential nutrient, its role in human health is increasingly recognized through its strong antioxidant and anti-inflammatory characteristics. In supplement form, Quercetin Dihydrate is generally standardized to high purity, often exceeding 95%, ensuring consistent quality for both research and commercial applications.
This compound exhibits a unique ability to neutralize free radicals and reactive oxygen species (ROS), helping to protect biomolecules like lipids, proteins, and DNA from oxidative damage. In addition, Quercetin Dihydrate may work synergistically with vitamin C and other antioxidants, enhancing their biological effects. The dihydrate structure contributes to higher stability compared to some other flavonoid derivatives, making it a reliable option for formulation in capsules, powders, and functional foods.
