Frequently Asked Questions
What is a supplement contract manufacturer?
A contract manufacturer (CM) produces dietary supplements on behalf of other brands. They handle some or all of the production process, from sourcing raw materials through finished packaging. This lets brands sell products without owning manufacturing facilities. CMs range from small batch specialists to large-scale producers making billions of doses per year.
What certifications should a contract manufacturer have?
At minimum, FDA registration and cGMP compliance under 21 CFR Part 111 are legally required. Beyond that, third-party certifications like NSF International GMP, USP Verified, or SQF add independent verification. Some retailers and distributors require specific certifications before they will carry a product.
How do minimum order quantities work?
MOQs vary widely, from 500 bottles for private label stock formulas to 300,000 units for large-scale manufacturers. Your MOQ depends on the dosage form, whether you want a stock or custom formula, and the manufacturer's equipment setup. Getting quotes from 3-5 manufacturers gives you a realistic range for your product type.
What is the difference between private label and custom formulation?
Private label means putting your brand on an existing formula the manufacturer already produces. It is faster and cheaper. Custom formulation means developing a unique formula for your brand: your own ingredient blend, doses, and specifications. Custom takes longer and costs more but gives you a differentiated product.
