Understanding and Selecting the Right Hard Gelatin Capsule 

This comprehensive guide explores everything you need to know about hard gelatin capsules, from their composition and manufacturing to their applications and selection criteria. We’ll delve into the various factors influencing capsule choice, helping you make informed decisions for your specific needs. Whether you’re a pharmaceutical professional, a supplement manufacturer, or simply curious about these ubiquitous containers, this article provides valuable insights.

What are Hard Gelatin Capsules?

Hard gelatin capsules are cylindrical containers used primarily for enclosing pharmaceuticals, dietary supplements, and other dry powders or small pellets. They’re made from gelatin, a protein derived from collagen, typically from animal sources (though vegetarian options are emerging). The two-piece design consists of a body and a cap, which fit together to seal the contents. Their widespread use is due to several key advantages: ease of swallowing, accurate dosing, and effective protection of the enclosed material from degradation.

Types of Hard Gelatin Capsules

Size and Capacity

Hard gelatin capsules come in a wide variety of sizes, denoted by numbers (e.g., size 000 to size 5), each corresponding to a specific capacity. Larger numbers indicate smaller capsules. The choice of size depends on the volume of the contents needing encapsulation. Precise sizing charts are readily available from capsule manufacturers.

Color and Opacity

Capsules are available in a vast array of colors and opacities. Color is often used for branding or to distinguish different formulations. Opaque capsules obscure the contents, while transparent capsules allow for visibility. The choice depends on the product and the desired aesthetic appeal.

Special Coatings

Specialized coatings can enhance the properties of hard gelatin capsules. These include enteric coatings for delayed release, moisture-resistant coatings for improved stability, and customized coatings for enhanced aesthetic or functional characteristics.
