About Capsule Sizes

Empty capsules come in standardized sizes, designated by numbers and codes. The most common sizes by capacity (smallest to largest): 5, 4, 3, 2, 1, 0, 00, 000. Size "0" holds approximately 500 mg of typical herbal powder and is the most common consumer size - fits comfortably in adult hands, easy to swallow, and matches the dose of most commercial single-herb capsules.

How to Fill Capsules

Pull the two halves apart. Fill the larger (body) half by gently scooping or pressing the herb powder into it. Press the smaller (cap) half back onto the body - the capsule will snap closed. For volume filling, a capsule-filling tray (we carry the Capsule Machine "0" for this purpose) lets you fill 24 or more capsules at once.
