Capsule Types We Manufacture: Tailored for Your Brand and Customers
At NutraSeller MFG, we believe that no two supplements are the same—and neither should their capsules be. That’s why we offer a diverse range of capsule types to meet your product’s unique needs and your customers’ preferences. Here’s what we bring to the table:
1. Gelatin Capsules: The Classic Choice
Time-tested and reliable, gelatin capsules are the go-to option for most traditional dietary supplements. They’re smooth, easy to swallow, and perfect for delivering powders and granules. Whether you’re launching a multivitamin or a herbal blend, gelatin capsules offer unbeatable performance and appeal.
2. Vegetarian Capsules: For the Plant-Based Consumer
As demand for plant-based products continues to rise, our HPMC (hydroxypropyl methylcellulose) capsules provide a perfect solution. These capsules are derived from natural, plant-based sources, making them ideal for vegan and vegetarian customers who value cruelty-free options.
3. Liquid-Filled Capsules: Innovation Meets Functionality
When it comes to oils, extracts, or liquid formulations, liquid-filled capsules are the ultimate delivery method. These capsules lock in potency, ensure precise dosing, and enhance bioavailability. Whether you’re packaging fish oil or CBD, liquid-filled capsules elevate your product to a whole new level of effectiveness.
4. Enteric-Coated Capsules: Precision for Targeted Absorption
Some supplements work best when they bypass the stomach and reach the intestines intact. Enteric-coated capsules are engineered for delayed release, ensuring active ingredients survive stomach acid and are absorbed where they’re needed most. Perfect for probiotics, enzymes, and sensitive compounds.
5. Custom Capsules: Your Brand, Your Way
Want to stand out on the shelf? With our custom capsule options, you can choose branded colors, imprints, or even unique shapes to reflect your brand identity. Whether it’s your logo, a signature color scheme, or a one-of-a-kind design, we make sure your capsules are as distinct as your vision.
Our Capsule Manufacturing Process: Precision at Every Step
Creating high-quality capsules isn’t just about filling shells—it’s about crafting a product that delivers results for your customers while elevating your brand. At NutraSeller MFG, we’ve perfected a six-step process that combines cutting-edge technology, rigorous quality control, and a client-first approach. Here’s how we bring your vision to life:
Step 1: Formulation Development – The Blueprint for Success
Every great product starts with a rock-solid formula. We work closely with you to refine and perfect your supplement blend, ensuring the active ingredients are stable, effective, and optimized for encapsulation. Whether it’s a potent herbal blend or a cutting-edge liquid supplement, we help you build the foundation for success.
Step 2: Raw Material Sourcing – Pure Ingredients, Superior Results
Quality begins with sourcing. We procure only the highest-grade, certified raw materials, meticulously testing for purity, potency, and safety. Every ingredient that enters our facility is thoroughly vetted to ensure it meets the highest industry standards. With us, you’ll never have to second-guess the integrity of your product.
Step 3: Encapsulation – Where Science Meets Efficiency
This is where the magic happens. Our high-speed encapsulation machines deliver precision at scale, perfectly filling each capsule with powders, granules, or liquids. Whether it’s gelatin or vegetarian capsules, our process ensures consistency in weight, fill, and overall quality—down to the very last capsule.
Step 4: Inspection and Quality Control – Excellence Guaranteed
We don’t just meet standards; we exceed them. Each batch undergoes both automatic and manual inspections to ensure capsules are uniform in weight, fill, and appearance. Advanced testing ensures stability, proper disintegration, and optimal dissolution rates, guaranteeing every capsule performs as promised.
Step 5: Packaging and Labeling – Your Brand’s Final Touch
Presentation matters. From blister packs and bottles to bulk packaging, we tailor the packaging to your needs. Pair this with our custom label design services, and your product will be retail-ready with a look that reflects your brand identity and attracts your audience.
Step 6: Final Testing and Release – Peace of Mind, Every Time
Before your product reaches the market, it undergoes rigorous final testing to ensure compliance with FDA regulations and any specific industry standards. Each batch comes with a Certificate of Analysis (COA), giving you and your customers the confidence that your capsules are safe, effective, and market-ready.
