Description

γ-Linolenic Acid (GLA) is an ω-6 polyunsaturated fatty acid (PUFA) of significant commercial and biochemical interest. It serves as a critical biosynthetic intermediate and a valuable direct supplement due to its anti-inflammatory and lipid-regulating properties. This high-purity compound is essential for manufacturers in the nutraceutical, pharmaceutical, and cosmetic industries, where consistent quality and reliable supply are paramount for product efficacy and safety.

Application

• Dietary Supplements & Nutraceuticals: A key active ingredient in capsules and softgels targeting inflammatory conditions, skin health (e.g., eczema), and hormonal balance.
• Pharmaceutical Intermediates: Used in the synthesis of prostaglandin E1 (PGE1) and other specialized lipid mediators for therapeutic applications.
• Cosmetic & Skincare Formulations: Incorporated into creams, serums, and lotions for its moisturizing, skin-barrier repairing, and anti-aging benefits.
• Clinical & Research Nutrition: A vital component in specialized medical nutrition products and infant formulas designed for specific metabolic needs.
• Biochemical Research: Employed as a standard or reagent in lipidomics, cell signaling studies, and metabolic pathway research.
• Functional Food & Beverage Fortification: Used to enrich health-focused food products with essential fatty acids.
