Short description: high-purity botanical extract standardized for isoflavones, formulated for supplements, beverages, and cosmetic actives.
When buyers ask about red clover powder, they usually mean a standardized extract made from Trifolium pratense blossoms. And yes, the hype around phytoestrogen-rich botanicals is back (again). To be honest, the market cycles every few years—yet the science and the specs matter more than the buzz.
Red Clover Extract Powder is typically produced from dried aerial parts—mainly flowers—using food-grade ethanol/water extraction. A modern facility will run percolation or counter-current extraction, followed by membrane clarification, concentration under vacuum, then spray-drying on maltodextrin or directly, depending on target potency. Actually, good manufacturers lean on HPLC to standardize total isoflavones (biochanin A, formononetin).
| Product Name | Red Clover Extract Powder |
| Botanical Name | Trifolium pratense L. |
| Active Markers | Total Isoflavones ≥ 20% or ≥ 40% (HPLC, biochanin A + formononetin) |
| Appearance | Brown to reddish-brown fine powder, 80–100 mesh |
| Moisture | ≤ 5% (loss on drying, AOAC) |
| Ash | ≤ 5% |
| Heavy Metals | Pb ≤ 0.5 mg/kg, As ≤ 0.5 mg/kg, Cd ≤ 0.3 mg/kg, Hg ≤ 0.1 mg/kg (ICP-MS, USP & EU limits) |
| Microbiology | TPC ≤ 10,000 CFU/g; Yeast/Mold ≤ 1,000 CFU/g; E. coli/S. aureus absent (USP & ISO) |
| Certifications | GMP, ISO 22000, HACCP; optional Halal/Kosher |
| Origin | NO.12, XIJIAN STREET, SHIJIAZHUANG CITY, HEBEI PROVINCE, CHINA |
Many customers say red clover powder blends cleaner than soy extracts and surprises with consistent color. Anecdotal, sure—but I’ve seen fewer batch-to-batch headaches when the supplier owns their standardization step.
| Vendor | Isoflavones | MOQ | Certs | Lead Time | Customization |
|---|---|---|---|---|---|
| HEX Herbal Medicine (China) | 20% / 40% (HPLC) | ≈ 25 kg | GMP, ISO 22000, HACCP | 7–15 days | Mesh, carrier, private label |
| Vendor A (EU) | 15% / 25% | ≈ 10–20 kg | ISO 22000, Kosher | 10–20 days | Label & small runs |
| Vendor B (US) | 20% (USP verified lot-by-lot) | ≈ 20 kg | cGMP, NSF | 7–12 days | Custom testing panels |
Note: specs and timelines are indicative; real-world use may vary by season, crop, and compliance checks.
A functional drink brand swapped soy for red clover powder at 0.35% in a 10% solids premix. Outcome: sensory astringency dropped slightly, filterability improved (fewer fines), and stability at 40°C/75% RH held for 3 months without color drift. Not earth-shattering, but in operations, that’s gold.
Common requests: 20% vs 40% isoflavones, 80–120 mesh, maltodextrin-free versions, and low-odor batches for gummies. Labels: Halal/Kosher, non-GMO statements, and allergens. If your brand story leans clean-label, push for carrier disclosure up front.
Bottom line? If you need consistent red clover powder with documentation, look for GMP + ISO 22000, a real HPLC chromatogram in the COA, and a pesticide panel that matches your market.
