 Capsules getting manufactured


In the dynamic world of nutraceuticals, capsule manufacturing plays a pivotal role in delivering safe and effective dietary supplements. Whether you're a brand looking to develop your own line of supplements or a distributor seeking high-quality products, understanding the ins and outs of capsule manufacturing is essential. By gaining a deeper understanding of capsule manufacturing, you'll be equipped with the knowledge to make informed decisions and ensure the production of top-notch nutraceuticals. In this comprehensive guide, we will explore what capsule manufacturing entails, the types of capsules produced, the process involved and the benefits of manufacturing capsules. 

What is Capsule Manufacturing?

Capsule manufacturing refers to the process of producing capsules, which are widely used in the nutraceutical industry to encapsulate different varieties of dietary supplements. Capsules provide a convenient and efficient delivery system for consumers, ensuring accurate dosing and easy consumption.

Types of Capsules Produced:

  1. Gelatin Capsules: These are the most common type of capsules in the industry, made from gelatin derived from animal sources. Gelatin capsules are suitable for a wide range of formulations and are available in different sizes and colors. 
  1. Vegetarian Capsules: For individuals with dietary restrictions or preferences, vegetarian capsules offer a suitable alternative to gelatin capsules. They are typically made from plant-based materials like cellulose or pullulan. Summit Rx provides full-service contract capsule manufacturing and packaging and specializes in certified organic capsules with pullulan shells. Here are the best explained pros and cons of Gelatin vs Vegetarian capsules.
  1. Enteric Coated Capsules: Enteric coated capsules have a special coating that prevents them from dissolving in the stomach. Instead, they dissolve in the intestines, allowing for targeted delivery of the active ingredients. This type of capsule is commonly used for supplements that are sensitive to gastric acid or need to be released in the intestine. Here is the importance of capsule coating in vitamin and minerals capsules.


The 4-Step Process of Capsule Manufacturing

Capsule manufacturing involves 4 key steps to ensure quality and consistency:

  1. Formulation Development: The process begins with the formulation of the supplement, including selecting the active ingredients and determining the appropriate dosage. 
  1. Preparing the Capsule Shells: Gelatin or vegetarian capsules are produced by mixing the respective materials with water and other additives. The mixture is then formed into capsules using specialized equipment. Learn more about various capsule sizes and their role in nutraceuticals.
  1. Filling the Capsules: The capsules are filled with the desired supplement through an automated filling process, ensuring accurate and consistent dosages.
  1. Sealing and Packaging: Once the capsules are filled, they are sealed to prevent leakage and contamination. The sealed capsules are then packaged into bottles, blister packs, or other suitable containers.

Why Manufacture Capsules?

Capsule manufacturing offers numerous advantages for both consumers and businesses:


  1. Versatility: Capsules can accommodate a wide range of formulations, including powders, liquids, and even small particles. 
  1. Accurate Dosage: Capsules provide precise dosing, ensuring consistent intake of active ingredients. Using our in-house powder manufacturing services, Summit Rx can help increase or decrease the particle size through dry granulation for obtaining capsules with the required amount of dosage. Here are the top 3 solutions for dosage accuracy in capsule manufacturing.
  1. Shelf Stability: Capsules offer protection against oxidation, moisture, and light, preserving the product's potency and extending its shelf life. 
  1. Consumer-Friendly: Capsules are easy to swallow and digest, making them a preferred choice for individuals who have difficulty with tablets or prefer a more convenient delivery method. We take pride in manufacturing capsules without or minimal use of excipients and making the final product with a “ clean label” tag.
