Understanding Capsule Sizes
Capsule sizes are labeled with a numerical value, with higher numbers indicating the smallest capsule size (such as 4 or 5) and the smaller number indicating the larger size. In cases where capsule sizes are indicated with "0" names, the 000s are the largest, while the 0s are the smaller. We sell gelatin capsules in sizes ranging from 000 to 4, and vegetarian capsules from sizes 00 to 2.
