- Semaglutide
7 Which delivery method uses a protective shell that releases the compounds later during digestion?
- Lipid nanoparticle delivery
- Microencapsulation
Microencapsulation surrounds a compound with a protective coating. The coating protects against stomach acid and helps more of it reach the right place intact. Learn more.
