Versatile Capsule Manufacturing: Precision, Purity, and Endless Possibilities.

At BRTNUTRA, we excel at encapsulating your vision. From complex herbal powders and probiotics to cutting-edge nootropics, we provide advanced, highly customizable capsule solutions. We are dedicated to delivering clean, effective, and reliable supplements that build your brand’s reputation for quality.

The Ultimate in Versatility & Efficacy: Why Choose Capsules?

Hard capsules offer distinct advantages for clean label formulation, precise delivery, and optimal absorption.

Unmatched Ingredient Versatility

Perfect for a wide range of powders, herbal extracts, vitamins, minerals, probiotics, granules, and even micro-pellets, allowing for complex multi-ingredient formulations.

Abundant Vegetarian/Vegan Options

We offer traditional gelatin capsules, as well as plant-based HPMC (hydroxypropyl methylcellulose) and Pullulan capsules, catering to clean label and diverse dietary needs.

Targeted-Release Technology

Available with enteric coating or advanced delayed-release capsules (e.g., DRcaps®) to protect sensitive ingredients like probiotics from stomach acid and ensure targeted intestinal delivery.

Clean Label Formulations

Capsules typically require fewer excipients (such as binders, disintegrants) than tablets, making it easier to achieve "clean label" product claims that meet premium market demands.

Fast Dissolution

Standard capsules dissolve quickly in the stomach, rapidly releasing active ingredients, ideal for products requiring fast onset of action (e.g., pre-workout supplements).

Cost-Effective Production

For many powdered formulations, hard capsules are a highly cost-effective choice for large-scale manufacturing.

Precise Selection: Which Supplements Are Best Suited for Hard Capsules?

Hard capsules are uniquely advantageous for certain active ingredients and product types, optimizing performance and consumer experience.

Powdered Herbal Extracts & Blends

For various herbal ingredients (e.g., Turmeric, Spirulina, adaptogens) and complex powdered formulations, hard capsules are an ideal encapsulation method, avoiding degradation from tablet compression.

Probiotics

Probiotics are sensitive to moisture, temperature, and stomach acid. Using HPMC vegetable capsules and enteric coating technology, hard capsules effectively protect probiotic viability, ensuring their successful delivery to the intestines.

Powdered Vitamins & Minerals

Powdered fat-soluble or water-soluble vitamins (e.g., Vitamin C, B-vitamins) and various chelated minerals benefit from hard capsules for precise dosing and excellent stability.

Enzymes

Digestive enzymes (e.g., proteases, amylases) are sensitive to stomach acid. Hard capsules (especially enteric-coated) protect their activity, allowing them to function effectively in the intestine.

Hygroscopic Ingredients

For moisture-sensitive ingredients, hard capsules provide a relatively sealed environment, slowing down moisture absorption and extending product shelf life while maintaining ingredient integrity.

Multi-Ingredient Formulations

When a product needs to combine multiple incompatible ingredients or those requiring different release rates, hard capsules can achieve complex fillings of **powders + micro-pellets/beads**, offering versatile solutions.

Engineering Excellence in Every Capsule.

We leverage state-of-the-art equipment and sophisticated processes to ensure every aspect from powder blending to capsule filling meets the highest standards.

Precision Dosing & Blending

Utilizing fully automatic high-speed capsule filling machines, we control dosing accuracy within ±2%. Our V-blenders and 3D mixers ensure perfect powder homogeneity before filling, even for materials with varying densities.

Versatile Content Handling

We not only handle standard powders but also challenging materials such as low-flow herbal powders, hygroscopic ingredients, and can achieve complex fillings of **powder + micro-pellets** or **powder + mini-tablets**.

Capsule Customization & Branding

We offer a full range of capsule sizes from 00 to 4. Customize capsule colors with natural pigments and enhance brand recognition by printing your logo directly onto the capsule body.

Strict Environmental Control

Our capsule filling facilities operate under stringent temperature and humidity control, ensuring the physical stability of capsules and the chemical activity of ingredients, especially for sensitive components like probiotics.

BRTNUTRA Hard Capsule Production Process: From Concept to Market

Every rigorous step, from raw material receipt to finished product dispatch, is designed to ensure exceptional quality for your products.

1. Raw Material Receiving & QA

All raw materials undergo stringent identification verification and quality testing (heavy metals, microbiology, active ingredient content, etc.) before warehousing, ensuring compliance with cGMP standards and client specifications.

2. Precise Weighing & Blending

Ingredients are precisely weighed according to the formula. Multi-stage blending using V-blenders or 3D mixers ensures perfect homogeneity of all active ingredients, forming the foundation for high-quality filling.

3. Capsule Filling

High-speed, fully automatic capsule filling machines precisely fill the blended powder or granular material into selected gelatin or plant-based capsule shells, with strict control over fill weight and encapsulation integrity.

4. Capsule Polishing & Inspection

Filled capsules are polished to remove surface powder residue and undergo multiple stages of automated and manual visual inspection to eliminate defective capsules (e.g., broken, empty, deformed).

5. Stability Testing & QA Release

Each batch undergoes critical quality parameter testing, with accelerated stability testing available upon client request. Products are only released by the Quality Assurance department after full compliance with all quality standards and regulatory requirements.

6. Packaging

Automated or semi-automated packaging according to client-specific needs (bottling, blister packs, sachets, etc.). This stage also includes label application, sealing, batch printing, and carton packing.

7. Finished Product Dispatch

All finished products, after final inspection and approval, are properly stored and prepared for shipment, ensuring product integrity before transportation and timely delivery to the client.

Certified Quality, Guaranteed Trust.

We rigorously adhere to the world’s most stringent industry standards, providing you with hard capsule products that meet the highest quality and safety requirements.

cGMP (Current Good Manufacturing Practices)

Our hard capsule production process, from powder blending to capsule filling, polishing, and packaging, strictly adheres to FDA’s cGMP standards, ensuring product purity, safety, and preventing cross-contamination.

NSF International Certification

As one of the most respected third-party certifications in the industry, NSF verifies that our products meet rigorous standards for purity, ingredient accuracy, and safety, bringing undeniable credibility to your brand.

Quality Control Process Highlights

Multi-Stage Testing: We implement rigorous multi-stage testing, including **raw material identification, homogeneity verification of blended powders, and comprehensive final product analysis** (e.g., microbiology, heavy metals, active ingredient content), ensuring every batch is of superior quality.
Dissolution Testing: Upon client request, we can perform detailed dissolution testing to ensure that capsules dissolve and active ingredients are released in the body as expected for optimal bioavailability.
