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.
