1. What are the key barriers to entering the Vitamin C Injection Market?
The market is protected by high capital costs for sterile manufacturing, rigorous GMP approval processes, and cold-chain logistics requirements. New entrants must invest at least $50 million in an FDA-inspected filling line and complete stability studies lasting 24 to 36 months. Established players like Pfizer and American Regent benefit from long-term hospital GPO contracts and validated regulatory dossiers.
