Contact RiverPharm to confirm your formulation requirements. We provide a competitive quote within 24 hours. Once approved, production begins — our custom capsule manufacturing process is built around precision encapsulation and strict in-process quality checks, making us a reliable capsule contract manufacturing partner for brands at any scale. The final product arrives bottled, labeled, and quality-inspected, ready to sell. Shipments go directly to Amazon FBA warehouses or your designated facility. A Non-Disclosure Agreement (NDA) is available before any proprietary details are shared.

Yes. Provide your existing formula, Supplement Facts panel, or Certificate of Analysis (COA). Our team evaluates it for regulatory compliance, ingredient interactions, and cost optimization. We can replicate your current specification exactly, improve bioavailability through ingredient upgrades, or reduce cost-per-unit without compromising your label claims. Contact us to initiate a reformulation assessment.

RiverPharm operates an in-house laboratory with advanced analytical instruments capable of performing all FDA-required testing in real time — a standard expected of GMP certified supplement manufacturers. All products additionally undergo third-party testing through ISO/IEC 17025-accredited independent laboratories, providing dual-layer quality verification. Testing covers ingredient identity, active ingredient potency, microbiological safety, heavy metal screening, and purity. A Certificate of Analysis (COA) is provided with every order.

RiverPharm does not enforce a strict minimum order quantity. For cost-effectiveness, we generally recommend a starting run of 2,000 units or more. Smaller production runs are available, though per-unit costs will typically be higher at lower volumes. MOQ and pricing vary based on your specific formulation, dosage form, and packaging requirements. Contact us to discuss your project and receive a tailored quote.

Unlike contract supplement manufacturers who bundle costs without visibility, RiverPharm provides itemized cost-per-unit quotes covering raw materials, manufacturing, third-party testing, label printing, and packaging — with no hidden fees. Before production begins, we share a clear cost breakdown so you have full visibility into all estimated expenses. Additional services such as expedited production or specialty packaging are quoted separately and confirmed before order placement.

RiverPharm requires a 50% deposit to initiate production, with the remaining balance due prior to shipment. This structure applies to all new orders and ensures materials procurement and production scheduling can begin without delay. For established customers with a proven order history, NET 30 payment terms may be available upon approval. Accepted payment methods include wire transfer, credit card, and ACH. All final payment terms are confirmed in the official quotation or manufacturing agreement before production begins.

Yes. As turnkey supplement manufacturers, RiverPharm handles Amazon FBA preparation and direct shipment to fulfillment centers across the United States — so your product goes from production line to Amazon warehouse without you managing logistics in between. FBA prep services include product packaging, label placement, carton labeling, pallet preparation, and carrier coordination. Brands should provide Amazon's current FBA requirements, shipment plans, barcode information, and destination warehouse details prior to shipment. RiverPharm ships finished products directly to your designated Amazon fulfillment center on your behalf.
