Description

Quercetin-3-Sophoroside is a specific flavonoid glycoside, a derivative of the well-known antioxidant quercetin. This compound is valued for its enhanced bioavailability and stability compared to its aglycone form, making it a sought-after ingredient for advanced nutraceutical and pharmaceutical formulations. It is primarily utilized by manufacturers in the dietary supplement, functional food, and cosmeceutical industries seeking to incorporate a high-purity, standardized bioactive flavonoid.

Application

• Dietary Supplements: As a key active ingredient in antioxidant, anti-inflammatory, and immune-support formulations.
• Functional Foods & Beverages: For fortification to enhance the nutritional profile and shelf-life of health-focused products.
• Cosmeceuticals & Skincare: Incorporated into serums and creams for its potential anti-aging and skin-protective properties against UV radiation.
• Pharmaceutical Research: Used as a reference standard or intermediate in the development of new therapeutic agents.
• Natural Colorants & Additives: Employed as a stable, natural pigment or functional additive in select food and cosmetic applications.
