Hersoncare Red Clover Isoflavones Extract – High-Purity Phytoestrogen Plant Extract

Latin Name: Trifolium Pratense L. | Part Used: Flowering Stems & Leaves

Minimum Order Quantity: 10 Kilogram | Certifications: ISO9001, HACCP, BRC, Kosher

1. Product Overview

Hersoncare’s Red Clover Isoflavones Extract is a premium Plant Extract derived from the flowering stems and leaves of Trifolium Pratense L. (red clover), a herbaceous plant renowned for its high phytoestrogen content. As a leading supplier of natural functional ingredients, we use a proprietary low-temperature extraction process to isolate and concentrate key isoflavones – ensuring maximum retention of bioactive compounds while eliminating impurities like chlorophyll and cellulose.

Unlike generic red clover extracts (which often have inconsistent isoflavone levels), our product is standardized to three high-purity grades: 10%, 20%, and 40% total isoflavones (HPLC-verified). These isoflavones – including daidzein, genistein, formononetin, and biochanin A – exhibit unique bidirectional hormone-regulating properties, making them a cornerstone ingredient in women’s health supplements. The extract appears as a fine yellow-brown powder with a characteristic plant aroma and excellent water solubility, enabling seamless integration into various formulations.

Complementary to our core product lineup, this extract pairs naturally with Vitamins and Minerals (e.g., calcium for bone health) and Food Grade Trehalose (as a stabilizer in oral supplements). It aligns with global consumer demand for clean-label, plant-based solutions for menopausal support, bone density maintenance, and overall hormonal balance – making it a trusted choice for nutraceutical, pharmaceutical, and cosmetic brands.

3. Product Features & Competitive Advantages

High-Purity, Standardized Isoflavones: Our extract is HPLC-verified to 10–40% total isoflavones – 2–3x higher than unstandardized "crude" extracts (which typically contain only 3–5% isoflavones). This ensures consistent efficacy across batches, eliminating the need for clients to test raw materials.
Bidirectional Hormone Regulation: The four key isoflavones (daidzein, genistein, formononetin, biochanin A) act as phytoestrogens, balancing estrogen levels in the body: they mimic estrogen when levels are low (e.g., menopause) and block excess estrogen when levels are high (e.g., premenstrual syndrome). Competitor extracts often lack formononetin, reducing this dual-action benefit.
Gentle Extraction Preserves Bioactivity: We use a water-ethanol co-solvent extraction process at ≤50℃, preserving 98% of isoflavone integrity. High-heat extraction (used by many suppliers) degrades 30–40% of bioactives, resulting in less effective products.
Clean-Label & Safety Compliant: Free of pesticides, heavy metals, PAHs, and irradiation – meeting EU Regulation (EC) No. 1881/2006, US FDA cGMP standards, and Chinese GB 1886.311-2021. This eliminates regulatory barriers for global markets.
Multi-Industry Versatility: Designed for cross-application use:
- Nutraceuticals: Tablets, capsules, and powders for menopausal support (paired with Vitamins and Minerals like calcium for bone health)
- Pharmaceuticals: Topical creams for hormonal skin issues or oral formulations for digestive health
- Cosmetics: Anti-aging serums (paired with Sodium Hyaluronate for moisturization) – isoflavones support collagen production and reduce fine lines
Long Shelf-Life & Stability: Low moisture content (≤5%) and oxygen-barrier packaging extend shelf-life to 2 years – 6–12 months longer than extracts with higher moisture levels. This reduces waste and inventory turnover for clients.
