Capsuline is one of the leading wholesale capsule suppliers in the United States, serving the global pharmaceutical and dietary supplement markets.  

Capsuline offers a vertically integrated supply chain model to ensure reliable long-term supply, complete traceability, and superior quality of raw materials

Our raw materials pass through strict quality control assessments before going to the manufacturing stage. We conduct multiple on-site audits every year (ISO-9001, cGMP, and others) to maintain good industry practices and to comply with U.S. and International laws and regulations.  

• Our gelatin capsules are made with 100% bovine hide, sourced from our cattle, and raised in South America. 
• Our empty vegetarian capsules are made of 100% plant-derived material (HPMC), sourced from a reputable source to guarantee quality and safety. 

• Our empty capsules are BSE-free, and both Kosher Pareve and Halal certified.
• Our vegetarian capsules (clear and white) are non-GMO certified and verified by the Vegan Society.
• Capsuline tracks each batch of capsules manufactured by lot numbers. This system allows us to provide all our customers with a certificate of analysis (COA) by-product. COAs are available by request, via email

We are proud to manufacture all our capsules in cGMP-certified facilities that comply with all international regulations; based in North and South America.  

Our manufacturing plants are equipped with the latest technologies, ensuring customers' long-term supply and superior quality.

Our quality control process is strict. Every step of the manufacturing process is documented and evaluated by batch. That allows us to offer high-quality and reliable capsules all the time. Our batch acceptance rate is 99%.
