Capsule ShellCapsule
Generic capsule shell where the label does not specify the material. Common materials are hypromellose (HPMC) for vegetarian capsules and gelatin for traditional capsules — both are GRAS-listed and safe. Fish gelatin and pullulan variants also exist.
On the label
As a dietary supplement, take 1 capsule, 1-2 times daily, with meals.
Labels usually say “with food” because it's gentler on the stomach, not because it absorbs better. Fasted absorbs more — start there, and switch to a light meal if it bothers you.
