Answers to Common Questions About Capsule Manufacturing
What is your minimum order quantity for capsule manufacturing?
Most capsule manufacturing projects begin at approximately 1,000–1,500 bottles. Minimums vary slightly by formulation complexity: capsules and powders generally start at 1,000–1,500 bottles, tinctures at 1,000–2,500 bottles, and tablets/softgels at 2,500 bottles. Stock formulas start as low as 500 bottles.
How long does capsule manufacturing typically take?
Most capsule projects are completed in approximately 4–8 weeks after your formula and order are confirmed. Timelines depend on ingredient sourcing, lab testing, packaging delivery, and scheduling. We provide a transparent, milestone-tracked timeline for your specific project.
Can you help develop my capsule formula?
Yes. Whether you have an existing formula that needs optimization or a brand-new concept, our in-house formulation chemists work with you to engineer an efficacious, compliant, and production-ready formula.
What capsule shell options do you offer?
Yes. We manufacture two-piece bovine gelatin, vegetarian HPMC (veggie), and acid-resistant capsules in sizes 00, 0, 1, and 2. We can also help evaluate shell options for extended-release formulation goals.

Which capsule sizes do you manufacture?
We regularly manufacture two-piece capsules in industry-standard sizes: Size 00 (high capacity), Size 0 (standard), Size 1 (medium), and Size 2 (compact). Sizing is determined by powder volume, bulk density, and desired serving size.
Do you manufacture probiotic capsules or other specialty formulations?
Yes. We manufacture probiotics, botanicals, herbals, multivitamins, and complex multi-ingredient formulations with specialized handling for strain viability, low-moisture encapsulation, and excipient compatibility.
How do you help ensure product quality?
