This guide provides a thorough overview of empty gelatin capsules, covering their types, uses, sourcing, and considerations for various applications. Learn about different capsule sizes, filling methods, and best practices for handling and storage. We’ll also explore common questions and address potential concerns related to using empty gelatin capsules.

Empty gelatin capsules are cylindrical containers made from gelatin, a protein derived from collagen. They are widely used as a convenient method for administering powders, liquids, or oils. These capsules offer a clean, easy-to-swallow alternative to tablets or loose powders, making them popular in various industries, including dietary supplements, pharmaceuticals, and nutraceuticals. The gelatin used is typically sourced from bovine or porcine sources, although vegetarian/vegan alternatives using seaweed-derived materials are increasingly available. Always check the product label to verify the gelatin source. Many companies offer a range of sizes, from very small (size 000) to large (size 5), accommodating different fill amounts and particle sizes.
Empty gelatin capsules come in various sizes, colors, and compositions. Size is denoted by a number, with smaller numbers indicating larger capsules. Colors can be customized for branding purposes or to differentiate products. Beyond standard gelatin, some capsules are designed with specific properties, such as enhanced moisture resistance or delayed-release capabilities. You can find capsules with different levels of hardness and transparency depending on your needs. When choosing your empty gelatin capsules consider your specific requirements for your application.
The size of an empty gelatin capsule is critical; the right size ensures proper filling and swallowing. The following table shows some common sizes and their approximate dimensions. These are average values, and slight variations may exist depending on the manufacturer.

High-quality empty gelatin capsules can be purchased from various suppliers. Many online retailers specialize in selling these products to individuals and businesses. When choosing a supplier, consider factors such as price, quality, and reputation. Look for companies with transparent sourcing practices and certifications ensuring product quality and purity. Ensure the supplier provides detailed product specifications, including size, material, and manufacturing processes.
Manually filling empty gelatin capsules is a common approach for smaller quantities. For larger-scale production, automated capsule filling machines are used. There are a variety of hand-held tools that can significantly improve the efficiency of filling capsules. Ensure proper hygiene and clean working conditions are maintained throughout the process to prevent contamination.

Proper storage is crucial to maintain the quality and integrity of your empty gelatin capsules. Store them in a cool, dry place, away from direct sunlight and moisture. The shelf life depends on the manufacturer and storage conditions, but typically ranges from one to two years. Always check the manufacturer’s instructions for specific recommendations.
Always handle empty gelatin capsules with care to avoid damage or contamination. Avoid exposing them to extreme temperatures or humidity. Ensure proper hygiene practices are followed during filling and handling.
