The Capsule Manufacturing Process
Capsules are one of the most versatile and widely used delivery forms in nutraceutical manufacturing due to their ease of consumption, accurate dosing, and formulation flexibility. They are suitable for a wide range of ingredients, including vitamins, minerals, herbal extracts, probiotics, and specialty compounds.
Our capsule manufacturing process supports both stock and fully custom formulations. We manage everything from ingredient sourcing and formulation support to encapsulation, in-process quality checks, and final inspection. Whether you are launching a new supplement or scaling an existing product, our process is designed to ensure consistency, compliance, and efficiency. With cGMP-controlled production and scalable capacity, we help brands bring high-quality capsule supplements to market with confidence.
Capsule Blend Preparation Process
Before capsules are filled, the formula must be carefully prepared to ensure uniformity, stability, and accurate dosing. Capsule blends are processed to achieve consistent particle size, proper flow, and optimal bioavailability.
The preparation stage typically follows one of two methods, depending on the ingredients and formulation requirements:
- Wet Granulation Process – Uses a binding liquid to form granules, improving blend uniformity and flow for complex or low-density ingredients.
- Dry Granulation Process – Compresses ingredients without liquids, ideal for moisture-sensitive formulas and heat-stable production.
Both methods ensure reliable encapsulation and consistent capsule quality.
Capsule Encapsulation Process
The nutraceutical capsule manufacturing process is completed only after the prepared blend is accurately filled into the capsule shell. Once all raw materials are gathered and verified, capsule shell production begins using carefully controlled conditions to ensure consistency and quality.
The capsule material is combined with hot, demineralized water and mixed under vacuum in specialized equipment to create a uniform solution. During this stage, additional hot water is gradually added, along with approved dyes and opacifiers when required, to achieve the desired color, opacity, and strength. The finished mixture is then molded around precision steel pins to form the capsule cap and body in the correct size and shape.
After molding, both capsule halves are dried together in a controlled environment. Temperature and humidity levels are continuously monitored to ensure optimal drying and structural integrity. Once dried, the capsule cap and body are trimmed to a precise 0.15 mm tolerance, assembled, and prepared for accurate filling, final inspection, and distribution.
Capsule Shell Options
Capsule shells are typically made from either animal-derived gelatin or plant-based vegetarian materials, providing options that cater to different formulation needs, dietary preferences, and ingredient compatibility requirements.
Gelatin Capsules
- Made from animal-derived sources such as bones and cartilage
- Commonly produced using bovine collagen
- Smooth texture and easy to swallow
- Fast dissolution for efficient ingredient release
- Compatible with a wide range of nutraceutical formulations
Vegetarian Capsules
- Made from plant-based materials such as hypromellose (HPMC)
- Pullulan capsules are produced through starch fermentation
- Suitable for vegetarian and vegan formulations
- Free from animal-derived ingredients
- Compatible with most nutraceutical formulas

Fill weights depend on the density of the powder or ingredients used.
What Capsule Numbers Mean
Capsule sizes are inversely related to their volume. For example, size “000” is the largest, while size “5” is the smallest.
Density and Volume Considerations
Capsule fill capacity is determined by the density of your active ingredients and excipients. Our experts can help you calculate the optimal size for your product.
Most Popular Capsule Sizes
The most commonly used sizes are 00 and 0, which provide a balance between volume and ease of swallowing.
Customization Options
Size Options: From 000 (largest) to 5 (smallest), we manufacture capsules that fit your exact needs.

Different Types of Capsule Contents
Capsules are one of the most versatile dosage forms in nutraceutical manufacturing, capable of delivering a wide range of ingredient types while ensuring accurate dosing and ease of consumption. The type of capsule content directly influences both performance and the choice of capsule shell.
Common Types of Capsule Contents
Powders
The most widely used capsule fill. Suitable for vitamins, minerals, herbal extracts, probiotics, and blends. Requires good flow and uniform particle size.
Pellets or Beads
Used for controlled or delayed release formulas. Pellets allow multiple ingredients with different release profiles in a single capsule.
Granules
Formed through wet or dry granulation to improve flow, stability, and content uniformity, especially for complex formulations.
Liquids and Semi-Solids
The most commonly used sizes are 00 and 0, which provide a balance between volume and ease of swallowing.
Common Types of Capsule Contents
- Some liquids and oils perform best in gelatin capsules due to their sealing properties.
- Moisture-sensitive or plant-based formulations may require vegetarian (HPMC or pullulan) capsules.
- Acidic or reactive ingredients may need specific shell compatibility to maintain stability.
Choosing the right combination of capsule content and shell type ensures product stability, bioavailability, and consistent performance throughout the product’s shelf life.

FAQ About Capsule Manufacturing
What is the MOQ for Capsules?
The minimum order quantity (MOQ) for capsules depends on the type of formula. Stock capsule formulas from Aurinutra can start as low as 1,000 bottles, while custom capsule formulations typically require a higher MOQ of 150,000 pieces (e.g., 2,500 bottles of 60-count). This ensures efficient production while maintaining quality and compliance.
Why Gelatin is Used in Capsules
Gelatin is widely used in capsule manufacturing because it:
- Protects contents from contamination and microbial growth
- Shields ingredients from light and moisture
- Ensures easy swallowing and smooth texture
- Provides fast dissolution for efficient ingredient release
- Maintains capsule integrity during storage and handling
Why Choose Capsules Over Tablets
Capsules are often preferred because they:
- Are easier to swallow than tablets
- Dissolve faster, ensuring quicker ingredient absorption
- Can encapsulate powders, liquids, or blends that may be difficult to compress into tablets
- Allow for customized release profiles such as delayed or enteric release
Should I Choose Gelatin or Vegetable Capsules?
The choice depends on your product and target market:
- Gelatin capsules are ideal for fast dissolution and traditional formulations.
- Vegetable capsules (HPMC or pullulan) suit vegan, vegetarian, or plant-based products.
- Consumer preference may dictate the choice, while some formulations require specific shell compatibility for stability and performance.
