Purity and Safety Standards
Because biopharmaceuticals are injected directly into the body, the "helper" ingredients must be cleaner than almost anything else on Earth.
Low-Endotoxin Grades: In 2026, excipients go through extreme cleaning to remove "endotoxins"—tiny bits of dead bacteria that could cause a fever.
Plant-Based Only: To avoid allergies or religious concerns, many 2026 excipients are moved away from animal sources (like gelatin) and are now made entirely from plants or minerals.
Non-Reactive: Scientists test every excipient to make sure it is "inert," meaning it won't react with the medicine or cause any unexpected side effects for the patient.
