Introduction: Understanding S-Equol for Industrial Applications
S-Equol has become a focal point in the nutraceutical and functional ingredient industry. As a biologically active metabolite derived from daidzein, a soy isoflavone, S-Equol is highly regarded for its stability, purity, and consistency—qualities essential for manufacturers and bulk suppliers. For businesses exploring functional foods, dietary supplements, or cosmetic formulations, sourcing high-grade S-Equol is critical to ensure product efficacy, safety, and regulatory compliance.
Unlike typical soy isoflavones, S-Equol demonstrates superior bioavailability and industry adaptability, making it a preferred choice for manufacturers seeking standardized, high-purity raw materials. By understanding its production, specifications, and applications, industry buyers can make informed sourcing decisions.
What is S-Equol?
S-Equol is a non-steroidal isoflavone metabolite produced via the biotransformation of daidzein by gut microbiota. In industrial terms, high-quality S-Equol is obtained through controlled fermentation and enzymatic conversion, ensuring a consistent chemical profile and regulatory compliance for large-scale applications.
Key characteristics include:
- Molecular Formula: C₁₅H₁₂O₃
- Molecular Weight: 244.25 g/mol
- Purity Range: ≥ 99% for industry-grade applications
- Physical Form: Fine, pale-yellow powder
S-Equol’s stability under standard manufacturing conditions makes it suitable for integration into capsules, tablets, beverages, or topical formulations without compromising quality.
