Natural Red Clover Extract

Natural Red Clover Extract - 8% Isoflavones | Water-Ethanol Extracted | CGMP Certified

Direct from GAP-certified planting bases in China's Jiangxi Province, our Natural Red Clover Extract delivers consistent isoflavone concentrations for supplement and functional food manufacturers.

Key separation: Not at all like soy-based options, this extricate gives all four major isoflavones (Biochanin A, Formononetin, Daidzein, Genistein) in characteristic ratios—ideal for soy-free formulations.

Product Specifications

Why Formulators Choose This Extract

Verified Source Traceability

Each batch traces back to specific growing regions in Hunan and Jiangxi provinces. Our agronomist team monitors cultivation from seedling selection through harvest timing.

What this means for you: Consistent phytochemical profiles across orders. We provide field-to-facility documentation when regulatory agencies request supply chain verification.

Complete Isoflavone Profile

Red clover naturally contains four isoflavones. Standard soy extracts provide only two (Daidzein and Genistein).

Formulation advantage: The methylated precursors Biochanin A and Formononetin offer different metabolic pathways. This complete spectrum supports "whole plant" marketing claims.

Optimized for Multiple Formats

Tablets & capsules: 80-mesh particle size ensures uniform blending. Bulk density (0.45-0.65 g/ml) works with standard encapsulation equipment.

Powdered beverages: Water-dispersible grade available for drink mixes (contact us for samples).

Topical formulations: Fine particle dispersion suits cream and serum bases. Residual ethanol <50 ppm meets cosmetic safety standards.

US Warehousing via Earth Made Nutritions

Four distribution centers across North America reduce lead times for orders under 500kg. We maintain 2-3 month inventory buffers.

Extraction Process

Our three-stage system preserves heat-sensitive isoflavones:

1. Dynamic extraction(40-60°C): Water-ethanol solvent extracts phytochemicals from dried plant material

2. Nano-membrane concentration: Removes impurities while retaining target compounds

3. Freeze-drying: Converts liquid concentrate to stable powder without high-heat degradation

Quality control: HPLC testing at three checkpoints verifies isoflavone concentration before, during, and after processing. We use aglycone reference standards (versus glycoside standards some suppliers use) for accurate potency measurement.

Common Applications

Women's Wellness Supplements

The 8% standardization enables precise dosing calculations. Typical finished product dosages range from 40-120mg isoflavones per serving.

Formulators often combine red clover with:

· Black cohosh for menopause support products

· Vitex for PMS-focused blends

· Calcium and vitamin D in bone health formulas

Functional Foods

The Natural Red Clover Extract withstands typical food processing temperatures (up to 85°C for 30 minutes). Stability testing shows <10% isoflavone degradation after 24 months in protein bar matrices.

Regulatory note: When used in foods, verify permitted levels with your local authorities. EU and US regulations differ for isoflavone-containing ingredients.

Skincare Products

Cosmetic chemists incorporate the extract into anti-aging formulations. The fine powder disperses in oil and water phases at 0.5-2.0% concentrations.

Solubility tip: Pre-disperse in propylene glycol or glycerin before adding to emulsions. This prevents agglomeration.

Handling & Storage Guidelines

Prevent caking: The powder is hygroscopic. Store sealed containers below 25°C in environments under 60% relative humidity.

Once opened: Use desiccant packs during manufacturing. Reseal unused portions immediately.

Shelf life: 24 months when stored properly in original packaging.

Frequently Asked Questions

How do I verify the isoflavone content matches your specification?

Each shipment includes a Certificate of Analysis with HPLC chromatogram. We use external labs for quarterly verification. Request our inter-lab comparison study showing <5% variance across three independent facilities.

What makes your HPLC testing more accurate than UV methods?

UV spectroscopy measures total compounds absorbing at specific wavelengths—it can't distinguish between individual isoflavones. HPLC separates each compound before quantification. We provide baseline-separated peaks for all four isoflavones.

Can I get samples before ordering 25kg?

Yes. We provide 100-200g samples at no charge for qualified formulators. Email frank@organic-herb.com with your company details and intended application.

Do you offer smaller pack sizes?

Our standard MOQ is 25kg. For development quantities (5-10kg), contact us for case-by-case evaluation. Small packs may incur repackaging fees.

Is the ethanol extraction solvent safe for supplements?

Residual ethanol content is <500 ppm (well below the 5,000 ppm USP limit for Class 3 solvents). We provide residual solvent testing data with each COA.

How does this compare to your 40% isoflavone grade?

The 40% extract undergoes additional purification steps. It costs approximately 3.5x more per kg but requires lower dosages. Most formulators use 8% for cost-effective products and 40% for premium lines.
