DOES IT WORK?
Hypromellose (HPMC) is hydroxypropyl methylcellulose, a plant-derived polymer used to make vegetarian capsule shells. It dissolves in your stomach within 20-30 minutes, releasing the contents inside. No health benefits on its own. It's simply the delivery vehicle. Popular with vegans, vegetarians, and people who avoid animal-derived gelatin for religious or dietary reasons.
