Industry trends

If you've ever filled a capsule at home, launched a supplement brand, or sourced materials for a pharmaceutical product, there's a good chance you've come across Capsuline. But who are we, really? And why does it matter where your capsules come from?

Capsuline is the world's leading online platform for pharmaceutical-grade, two-piece empty capsules. Based in Dania Beach, Florida, with manufacturing operations in North and South America, Capsuline serves thousands of customers globally, from major pharmaceutical manufacturers to independent formulators. The origin and composition of a capsule shell directly affects product quality, label compliance, and consumer trust, which is why sourcing from a verified, traceable supplier matters.

From the Ground Up: A Vertically Integrated Supply Chain

Maintaining capsule integrity from the moment they are manufactured to the moment they reach your hands is not a given in this industry, it requires deliberate control over every step of the supply chain. That is precisely what Capsuline has built.

Our gelatin capsules are made with 100% bovine hide, sourced from South America, and produced in cGMP-certified facilities that comply with U.S. and international regulations.

Our vegetarian capsules are made from HPMC (Hydroxypropyl Methylcellulose), a 100% plant-derived material sourced from softwood species like Pine and Spruce. Every batch is non-GMO certified and verified by the Vegan Society.

Where We Make Our Capsules

Every capsule in our catalog is manufactured in facilities located in North and South America a deliberate decision that has a direct impact on our customers:

• Faster shipping and fulfillment across the U.S. and global markets
•  A batch acceptance rate of 99%
• Complete traceability by lot number, with Certificates of Analysis (COAs) available on request

We conduct multiple on-site audits every year,  ISO-9001, cGMP, and others. Because it is the standard we hold ourselves to.

A Capsule for Every Need

Capsuline specializes in one thing: empty capsules. And within that focus, the range is broader than most people expect, covering different materials, sizes, formats, and use cases.

Our gelatin and vegetarian empty capsules come in standard numerical sizes: 000, 00E, 00, 0E, 0, 1, 2, 3, 4, and 5. Not sure which size is right for your formulation? This video breaks it down:
