What Is Genistein 98%?
Genistein 98% refers to high-purity genistein isoflavone powder with a minimum 98% content tested by HPLC. It is naturally extracted from mature Sophora japonica fruit, a classic natural phytoestrogen and flavonoid compound with the CAS number 446-72-0. As a professional plant extract manufacturer, we produce it via low-temperature purification and recrystallization to reduce impurities. This off-white crystalline powder boasts stable physical properties, excellent antioxidant activity, and is widely applied in dietary supplements, skincare cosmetics and pharmaceutical research fields.

Key Benefits of Genistein 98%
1. Phytoestrogen & Hormonal Balance
Genistein binds to estrogen receptors (ERα and ERβ) and acts as a selective estrogen receptor modulator (SERM). It is widely formulated into women’s health supplements to help ease menopausal symptoms—hot flashes, night sweats, and mood fluctuations—without the side effects associated with synthetic hormone therapy.
2. Antioxidant & Anti-Aging
As a potent free-radical scavenger, Genistein enhances endogenous antioxidant enzymes (SOD, GSH-Px) and neutralizes UV-induced reactive oxygen species. In anti-aging skincare, it supports collagen synthesis, reduces the appearance of fine lines, and helps protect against photoaging.
3. Bone Health & Cardiovascular Support
Clinical research links Genistein intake to improved bone mineral density in postmenopausal women, supporting its use in bone-health formulations. It also promotes vascular endothelial function, supports healthy lipid metabolism, and may inhibit thrombus formation—making it valuable for cardiovascular supplements.
4. Metabolic & Cellular Health
Genistein modulates insulin signaling and supports healthy blood glucose management. As a recognized tyrosine kinase inhibitor (PTK inhibitor, IC₅₀ ≈ 2.6 μM), it is extensively studied in oncology and cellular-signaling research for its role in inducing cell-cycle arrest and apoptosis in hormone-dependent cancer cell lines.
5.Applications by Industry
Nutraceuticals & Dietary Supplements
Genistein 98% is a go-to active for women’s health capsules, bone-density tablets, antioxidant blends, and cardiovascular formulas. Typical dosage forms include hard capsules, tablets, and softgels. Our powder’s fine particle size supports uniform blending and tablet compression.
6.Cosmetics & Skincare
Formulators incorporate Genistein 98% into anti-aging creams, serums, eye treatments, and barrier-repair emulsions. Its phytoestrogen activity makes it especially suited for mature-skin and post-menopausal skincare lines. Recommended use level: 0.1–1.0%.
7.Pharmaceutical & API Research
As a well-characterized isoflavone with documented mechanisms, Genistein 98% serves as a pharmaceutical intermediate and research reference material for studies in chemoprevention, hormonal therapy, and signal-transduction pathways. It is compatible with USP-grade reference standards.
8.Functional Food & Beverages
Genistein 98% can be fortified into functional drinks, plant-based protein products, and nutritional foods targeting middle-aged and elderly consumers.
