Capsule Types We Manufacture

Gelatin Capsules

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.

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.

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.

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.

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.

Size Matters

Choosing Your Perfect Capsule Size
