Description

Secoisolariciresinol Diglucoside is a naturally occurring lignan compound, primarily extracted from flaxseed (Linum usitatissimum). This phytochemical is valued for its potent antioxidant properties and role as a key metabolic precursor to mammalian lignans like enterodiol and enterolactone. It is a critical ingredient for manufacturers in the nutraceutical, pharmaceutical, and functional food industries seeking to develop products focused on hormonal balance, cardiovascular health, and cellular protection.

Application

• Nutraceutical & Dietary Supplements: Core ingredient for capsules, tablets, and powders targeting antioxidant support, hormonal health, and menopause symptom management.
• Functional Food & Beverage Fortification: Used to enrich health-focused foods, beverages, and nutritional bars with bioactive lignan content.
• Pharmaceutical Research & Development: Serves as a reference standard and active pharmaceutical ingredient (API) in studies related to cancer prevention, metabolic syndrome, and estrogen-related therapies.
• Cosmeceuticals: Incorporated into anti-aging skincare formulations for its antioxidant and potential phytoestrogenic benefits to the skin.
• Veterinary Health Products: Used in supplements for companion animals and livestock to promote overall wellness.
• Analytical & Quality Control: Employed as a high-purity certified reference material (CRM) for HPLC and LC-MS analysis in laboratory settings.
