Solving Stability Issues Enteric-Coated Fish Oil Capsules
Solving Stability Issues: Enteric-Coated Fish Oil Capsules – Tianzhong Kangyuan Protects Potency from Factory to Gut
Omega-3 fatty acids are among the most sensitive nutrients in the nutrition vitamins supplements industry. As polyunsaturated fatty acids (PUFAs), they are highly susceptible to oxidation—a degradation process that compromises bioavailability, creates unpleasant rancidity, and ultimately reduces therapeutic efficacy . Tianzhong Kangyuan Pharmaceutical Group Co., Ltd. solves these stability challenges through advanced enteric-coated capsules technology that protects sensitive fish oils through two critical stages: shelf storage and gastrointestinal transit.
The Dual Oxidation Challenge for Fish Oil Capsules
Dietary Capsules containing fish oil face oxidative threats at multiple points. During storage, exposure to oxygen, light, and elevated temperatures triggers lipid peroxidation—measured through peroxide values and anisidine values that indicate rancidity progression . Quality manufacturers maintain peroxide values below 10 milliequivalents O2/kg and anisidine values under 30, thresholds our vitamin e dietary supplement formulations consistently meet through rigorous antioxidant protection .
The second oxidative challenge occurs during digestion. Research demonstrates that the highly acidic gastric environment can result in up to 80% loss of omega-3 bioactivity before the oil reaches intestinal absorption sites . This gastric-phase degradation forces conventional vitamin food supplement manufacturers to overdose capsules—adding more oil than necessary to compensate for stomach losses.
Tianzhong Kangyuan: Engineering Enteric Protection
Tianzhong Kangyuan Pharmaceutical Group Co.,Ltd manufactures enteric-coated capsules using pharmaceutical-grade polymers that remain intact in gastric fluid (pH 1.2) and release precisely when they reach the small intestine's higher pH environment (5.5-7.0) . In simulated gastric conditions, enteric-coated formulations release only 10% of lipid content compared to 70% release from standard capsules—demonstrating effective gastric resistance .
This protection offers multiple advantages:
Preserved Bioactivity: By shielding PUFAs through the oxidative gastric phase, enteric technology ensures more intact omega-3 reaches intestinal absorption sites .
Extended Release Profile: While standard capsules release 50% of contents within 90 minutes in intestinal conditions, enteric Dietary Capsules provide sustained release over 6 hours—potentially prolonging therapeutic effects .
Reduced Side Effects: Enteric coating minimizes the "fishy burp" phenomenon that causes patient non-compliance, as documented in clinical studies of coated fish oil preparations for Crohn's disease patients .
Service Response: Comprehensive Stability Solutions
Understanding that oxidation management requires integrated approaches, our US-dedicated account team provides complete technical support. We incorporate natural antioxidants including tocopherols (vitamin E) and rosemary-derived carnosic acid into nutrition vitamins supplements formulations, which demonstrate stronger antioxidant effects than vitamin E alone in long-term storage studies . For vitamin e dietary supplement compatibility, our formulation scientists optimize antioxidant blends that work synergistically with enteric protection.
