1. What Are Gelatin Capsules?

Gelatin capsules are one of the most commonly used forms of oral dosage delivery. These capsules are made from gelatin, a natural protein derived from animal collagen. They are prized for their biocompatibility and versatility, as they can be used for both powdered substances and liquid formulations.

Types of Gelatin Capsules

  • Hard Gelatin Capsules: These are composed of two rigid shells fitted together and are typically used for powders, granules, or small tablets.
  • Soft Gelatin Capsules: Unlike hard capsules, these are flexible and seamless, ideal for containing liquids, oils, or pastes.

Why Gelatin Capsules?

  • They dissolve quickly in the stomach, ensuring fast absorption of active ingredients.
  • Tasteless and odorless, they are consumer-friendly and easy to swallow.
  • They provide a robust barrier against moisture and oxygen, extending the shelf life of the contents.

By using gelatin capsules, you ensure precision, convenience, and efficacy in delivering your products to end users.

3. Applications of Gelatin Capsules

Gelatin capsules are not just limited to pharmaceutical applications. Their versatility extends into multiple industries.

Pharmaceutical Industry

Gelatin capsules are widely used for prescription medications and over-the-counter drugs. They can encapsulate both fast-acting and controlled-release formulations, making them adaptable to a variety of medical needs.

Nutraceutical and Dietary Supplements

For vitamins, minerals, herbal extracts, and dietary supplements, gelatin capsules are a preferred choice. Products like fish oils, probiotics, or CBD oils are often encapsulated to maintain potency and ensure a pleasant consumer experience.

Food and Cosmetic Industries

Beyond medicine, gelatin capsules are also used in food flavoring systems and the beauty industry. Encapsulated supplements that promote skin health, for example, are gaining popularity in the cosmetic sector.

Whether your focus is medicine, nutrition, or beauty, gelatin capsules provide a reliable solution for product delivery.

 

4. How Are Gelatin Capsules Made?

Understanding how gelatin capsules are manufactured highlights the precision and care involved in their creation.

Gelatin Preparation

The process begins with extracting collagen from animal sources like bovine, porcine, or fish. This collagen undergoes hydrolysis to form gelatin, which is then purified and mixed with water and plasticizers to achieve the desired consistency.

Capsule Formation

For hard gelatin capsules, pins are dipped into the molten gelatin solution to form the capsule shells. These are dried, trimmed, and separated into two halves: the cap and the body. Soft gelatin capsules, on the other hand, are created using rotary die technology, where the fill material is encapsulated between two sheets of gelatin.

Quality Control

Each capsule is tested for uniformity, strength, and moisture content to ensure compliance with industry standards. Rigorous quality checks guarantee that the capsules meet both functional and aesthetic requirements.

 

5. Choosing the Right Gelatin Capsule

Selecting the perfect gelatin capsule for your product depends on several factors.

Size Matters

Gelatin capsules come in sizes ranging from 000 (the largest) to 5 (the smallest). The right size will depend on your dosage requirements and consumer preferences. Capsuline’s experts can guide you in choosing the best fit.

Color and Finish

Opaque capsules are ideal for light-sensitive contents, while clear ones let consumers see what’s inside. You can also select unique finishes, such as metallic or pearlized, to enhance product appeal.

Compatibility with Fill Material

Hard capsules are great for powders, while soft capsules work best for liquids or oils. Understanding the nature of your fill material is crucial in making the right choice.

 

6. Common Myths About Gelatin Capsules

There are many misconceptions surrounding gelatin capsules. Let’s clear them up:

Myth: Gelatin Capsules Are Unsafe

Gelatin capsules have been used safely in medicine for decades. Allergenic concerns are minimal, as manufacturers adhere to strict labeling requirements.

Myth: They’re Only Animal-Derived

While traditional gelatin comes from animal sources, vegetarian alternatives like HPMC capsules are widely available for ethical or dietary needs.

Myth: They’re Expensive

Thanks to Capsuline’s cost-efficient manufacturing, high-quality gelatin capsules are accessible and affordable, even for small businesses.

 

7. How to Store and Handle Gelatin Capsules

To maintain their quality, proper storage and handling are essential.

Optimal Storage Conditions

Store capsules in a cool, dry place with temperatures between 15–25°C and humidity levels of 35–50%. Exposure to high humidity can make capsules sticky, while low humidity may cause brittleness.

Handling Tips

Avoid stacking capsules under heavy weights to prevent deformation. For large-scale production, use automated filling equipment for consistent results.

Shelf Life

Gelatin capsules typically have a shelf life of 3–5 years when stored correctly. By following proper storage practices, you can maximize their longevity.
