Resveratrol

Resveratrol (CAS 501-36-0) is a naturally derived polyphenol sourced primarily from Japanese knotweed and grape-derived materials. It functions as an antioxidant active across nutraceutical, cosmetic, and pharmaceutical formulations. Buyers source it as a standardized botanical extract or as a highly purified synthetic equivalent depending on application requirements. In dietary supplements, it is formulated into capsules, tablets, and softgels.

These products target antioxidant and longevity-positioned product lines. Cosmetic formulators incorporate it into anti-aging serums, creams, and facial treatments where it provides antioxidant protection for the skin matrix. It supports UV-induced oxidative stress mitigation in various topical applications. Food and beverage manufacturers use it as a functional ingredient in fortified products where clean-label positioning is relevant.

Pharmaceutical researchers and contract manufacturers also source high-purity grades for use in investigational formulations. It is also utilized in standardized reference applications across the global industry. The material is supplied as a white to off-white crystalline powder. Standard grades include 98%+ purity (HPLC) for pharmaceutical and nutraceutical use, with food-grade and cosmetic-grade specifications available.

Suppliers ensure compliance with international quality standards such as USP, FCC, and Ph.Eur. to meet regulatory needs. Botanical extract forms are commonly offered alongside synthetic high-purity material.
