NAD+ Liquid Manufacturer for Supplement Brands

NAD+ liquids are typically filled into amber glass dropper bottles, PET bottles or single-serve sachets. EUPHM runs four liquid filling lines with inline checkweighing and nitrogen flushing. Fill accuracy is ±1% for bottles from 15 ml to 60 ml. Changeover between SKUs takes 4–6 hours, which keeps small retail batches practical. We can run 1,000-unit pilot batches and scale to 60,000 bottles per day without changing the formulation or supplier.

Every batch is mixed in jacketed stainless steel tanks with temperature control between 2°C and 8°C where required. For NAD+ solutions, we use deionised water and adjust pH to the target range before sterile filtration. Filling rooms are classified to ISO 8 or better, depending on the preservation system. If you already have a formula, we can match it. If not, our team can develop a shelf-stable base from 1,000 units.

NAD+ is sensitive to heat, light and high pH. A liquid format needs careful buffering and chelation to slow degradation. EUPHM formulates with sodium or potassium buffers, EDTA alternatives and antioxidants such as sodium metabisulfite where permitted. We test accelerated stability at 40°C/75% RH for 3 months and real-time stability for 12–24 months. Typical shelf life for a well-buffered NAD+ liquid is 18 months unopened.

Taste is the second constraint. NAD+ has a bitter, slightly metallic profile. We can mask it with glycerin, stevia or monk fruit, and adjust acidity with citric or malic acid. Preservative systems include potassium sorbate and sodium benzoate, or a preservative-free hot-fill option for 30 ml bottles. Flavour options range from neutral to berry, citrus or mint. We provide 2–3 flavour iterations during sampling at no extra cost.

EUPHM operates a GMP-certified facility with ISO 22000 and HACCP systems. Incoming NAD+ raw material is tested for identity, purity and heavy metals by HPLC and ICP-MS. Each production batch has a certificate of analysis covering assay, pH, microbial limits and fill weight. We retain samples for 24 months. Documentation for US, EU, UK and Middle East shipments includes COA, MSDS, halal certificates, and organic transaction certificates where applicable.

For US-bound products, our facility is FDA-registered. We do not claim FDA approval for any supplement. Labels can be reviewed for FDA and EU compliance before printing. Lead times for export documents are 3–5 working days after batch release. We ship FOB Shenzhen or Yantian, with air freight options for pilot runs. MOQ for retail bottling starts at 1,000 units per SKU, and we support private label and white label formats.

NAD+ liquids are typically filled into amber or cobalt glass dropper bottles (15 ml, 30 ml, 50 ml, 60 ml) or into PET bottles for larger formats. For single-serve formats we offer 10–30 ml stick packs and 15–30 ml sachets with tear notches. Closures include dropper assemblies with graduated pipettes, tamper-evident screw caps and child-resistant options where required. Bottles can be supplied with induction seals or pressure-sensitive liners. Cartons are specified with dimensions, board grade and print process.

For US-bound dietary supplements, labels must carry the Supplement Facts panel, serving size, amount per serving, percent daily value where applicable, other ingredients, and the mandatory allergen declaration. We also include the “Distributed by” statement, net quantity, and storage instructions. Lot number and expiry date are inkjet-coded on the bottle and on the carton, with a check that the two match. We can apply FDA-compliant labels supplied by the brand owner, or coordinate label printing through approved vendors.

Retail-ready packing includes Amazon FNSKU labels, poly-bagging where required, and carton markings that meet the retailer’s inbound requirements. We can print and apply FNSKU labels in-house and confirm that each unit is scannable before sealing. Master cartons are typically 5-ply corrugated with a maximum weight of 15 kg for manual handling, or up to 20 kg where the buyer agrees. Pallet configurations are built to a standard 1,200 × 1,000 mm or 1,200 × 800 mm footprint, stretch-wrapped and edge-protected.

For EU retail, we can include the responsible person address, the EC number where applicable, and the batch code in a format the buyer specifies. We do not write or approve claims; the brand owner is responsible for label content and claim substantiation. Artwork is checked against a pre-press checklist covering barcode grade, font size for net quantity, and country of origin. A digital proof is issued for written approval before printing. Packaging components are inspected on receipt for dimensions, colour and print defects.

Sampling for NAD+ liquids starts with a formulation brief and target fill size. We issue a quotation within 2–3 working days and produce samples in 7–10 working days after receipt of the brief and any reference sample. Sample cost is quoted separately and is typically credited against the first mass-production order. If a new label or carton is required, add 5–7 working days for artwork and printing before filling can be scheduled.

Mass production runs 20–35 working days after sample approval and receipt of packaging components. This window covers raw material release, bulk preparation, sterile filtration, filling, capping, coding, and quality release. If components are delayed, the production slot may be reallocated, so we ask for component delivery dates at least 10 working days before the planned fill date. We provide a production schedule with milestones and a weekly status update once the batch is in process.

Shipping options include air freight (5–10 days door-to-door for most destinations) and sea freight (25–40 days port-to-port depending on route). We quote EXW, FOB Shenzhen or Hong Kong, and DDP for select markets. DDP quotes include duties and delivery to the buyer’s warehouse but exclude destination storage or demurrage. For small pilot orders, air freight is usually more economical; for full pallets, sea freight reduces unit cost. We can consolidate with other suppliers on request.

Documents provided with each shipment include the commercial invoice, packing list, COA per lot, safety data sheet (MSDS) in the required language, and a free-sale certificate where the destination requires one. For plant-based ingredients, a phytosanitary certificate can be arranged if the importing country asks for it. Certificates of origin can be issued for preferential tariff treatment where applicable. We do not provide a certificate of analysis for a lot that has not been produced; each COA is tied to a specific batch record.
