This formula's own materials directly disclose a clean hypromellose capsule shell — worth understanding what that specifically means if a vegan or vegetarian diet matters to your decision.
This formula's own materials describe the capsule as "a clean hypromellose capsule" made from plant cellulose, non-GMO and free from gluten, dairy, soy and other major allergens.
Unlike a gelatin-based shell, which is animal-derived, hypromellose (HPMC) is a plant-cellulose-based capsule material — worth confirming this detail matches what's stated on your own bottle if it matters to your decision.
