Active Ingredients
The core value of our Genistein 98% lies in its ultra-high purity and targeted active composition, setting it apart from conventional isoflavone blends that dilute genistein with other less effective compounds. We prioritize the bioactive, free aglycone form of genistein-unlike most products that contain bound glycosides (which require intestinal hydrolysis to become active)-ensuring immediate efficacy:
- Genistein (Free Aglycone): The primary active component, with a guaranteed 98% concentration (min. 98.0%, max. 99.5%). This is the bioactive form of genistein (5,7,4'-trihydroxyisoflavone), a natural plant estrogen (phytoestrogen) with a molecular structure similar to human estrogen, enabling it to bind to estrogen receptors (ERα and ERβ) and exert balanced hormonal effects. Unlike glycosylated genistein (e.g., genistin), our free aglycone form is directly absorbed by the intestinal tract without needing to be broken down, delivering faster and more consistent results.
- Minor Bioactive Isoflavones: Trace amounts (≤2%) of naturally occurring co-isoflavones, including daidzein and glycitein, which work synergistically with genistein to enhance its overall efficacy. These minor components are retained intentionally to mimic the natural isoflavone profile of soybeans, supporting holistic health benefits without diluting the core genistein concentration.
- Natural Antioxidant Co-Factors: Small quantities of soy-derived phenols and trace minerals (e.g., magnesium, zinc) that complement genistein's antioxidant activity, protecting cells from oxidative damage and amplifying its anti-aging effects. These co-factors are naturally present in the raw soybean source and preserved during our gentle extraction process.
- Simply put, our Genistein 98% focuses on quality over quantity-prioritizing the most bioactive form of genistein at the highest purity, rather than filling the product with inactive ingredients or diluted blends.
Source Transparency: Natural vs. Synthetic
We at TIANJIN YINAO are aware that various formulas have various label specifications. To fit the positioning of your business, we provide both quality sources of genistein.
| Feature | Natural Genistein | Synthetic Genistein |
|---|---|---|
| Origin | Extracted from Sophora japonica (standard) or Soy. | Chemical synthesis (identical molecular structure). |
| Purity | Standardized to ≥≥ 98% (HPLC). | Ultra-high purity, typically ≥≥ 99%. |
| B2B Benefit | Ideal for "Plant-based" and "Clean Label" brands. | Most cost-effective for large-scale industrial supply. |
| Traceability | Full botanical identification provided. | Consistent batch-to-batch stability. |
Women's Health Application Cases
Genistein is a potent isoflavone that acts as a natural selective estrogen receptor modulator (SERM). It is an essential component of sophisticated women's health practices.
Menopause Management (Hormonal Balance)
Objective: Reduction of hot flashes and night sweats.
Synergy: Combine Genistein with Black Cohosh Extract or Red Clover Isoflavones.
Formulation Logic: Without the dangers of synthetic hormone replacement, genistein relieves menopausal symptoms by binding to ER-β receptors.
Bone Density & Osteoporosis Support
Objective: Prevention of postmenopausal bone loss.
Synergy: Pair Genistein with Vitamin D3, Vitamin K2 (MK-7), and Calcium AEP.
Formulation Logic: According to clinical research, genistein inhibits bone resorption while increasing osteoblast activity, or bone-forming cells.
Function
- Anticancer effect: It can induce tumor cell apoptosis by inhibiting tyrosine protein kinase (PTK) and topoisomerase, and inhibit breast cancer, prostate cancer, etc.
- Cardiovascular protection: Regulating hormone receptor signaling pathways to improve cardiovascular health.
- Neuroprotection: By activating the PI3K/Akt signaling pathway, it improves neuronal damage caused by high glucose.
- Other applications: As a dietary supplement, improve menopausal symptoms and prevent osteoporosis.
