Description

cis-4,7,10,13,16,19-Docosahexaenoic Acid Sodium Salt is the sodium salt form of the essential ω-3 fatty acid DHA (docosahexaenoic acid). This highly purified, water-soluble derivative is critical for enhancing bioavailability and stability in advanced formulations. It is primarily utilized by manufacturers in the pharmaceutical, nutraceutical, and advanced food ingredient sectors for its vital role in cognitive and cardiovascular health support.

Application

• Pharmaceutical Intermediates: As a key active pharmaceutical ingredient (API) or precursor in prescription-grade ω-3 supplements and cardiovascular medications.
• Nutraceutical Formulations: For high-potency dietary supplements, including softgel capsules, powders, and liquid emulsions, requiring superior purity and stability.
• Infant Formula & Clinical Nutrition: As a vital additive to infant formula and medical nutrition products to support neurological development and meet stringent regulatory standards.
• Biomedical & Cell Culture Research: Used in specialized cell culture media and as a biochemical reagent for studying lipid metabolism and cellular function.
• Functional Food & Beverage Fortification: For the enrichment of foods and beverages, such as dairy alternatives, health drinks, and baked goods, where a stable, soluble form of DHA is required.
• Cosmeceuticals: Incorporated into advanced skincare formulations for its anti-inflammatory and skin-barrier supporting properties.

Quality Control

Our cis-4,7,10,13,16,19-Docosahexaenoic Acid Sodium Salt is manufactured under strict quality management systems. Each batch is tested to ensure compliance with relevant standards for pharmaceutical and food-grade applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C (refrigerated) to minimize oxidation and hydrolysis. The container must be kept in a cool, dry place with low humidity due to its hygroscopic nature. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
