Nutraceutical ingredients your formulation team can actually rely on

Most powdered ingredients start at 25 kg. Higher-value standardised extracts start lower, often at 5 kg, and packaging components are sold by the carton. Qualified buyers evaluating a material can request a paid sample of 100 g to 1 kg before committing to a full order.

Yes. Every lot ships with a lot-specific Certificate of Analysis showing identity, assay, heavy metals, microbiological results and residual solvents where relevant. Safety Data Sheets, allergen statements, and Kosher and Halal certificates are available for every product on request.

We are a contract manufacturing partner, and we are explicit about which role applies to each line rather than blurring them.

For bulk raw materials we operate qualified supply programmes: we specify, audit and release the material, and we tell you plainly when we are the producing site and when we are not. For finished products we act as your turnkey manufacturing partner — we develop the formulation and manage the production run under cGMP in an FDA-registered facility through our certified partner network, under our specification, our batch documentation and our release testing.

What you get either way is a single accountable party holding the specification, the documentation and the lot traceability.

It means you own the product and we run the project that produces it. You bring a formula, a competitor sample you want matched, or simply the label claim you want to make. We develop the formulation, manage production under cGMP in an FDA-registered facility through our certified partner network, arrange the testing, then pack and label the finished goods under your brand.

You control the actives and their doses, the dose form, the pack format and the artwork. We control the specification, the qualification of every input, the batch records and the release documentation. The finished goods are yours outright — there is no Zenith branding on them and no restriction on where you sell them.

Materials held in US stock ship within 3–7 business days of a cleared order. Made-to-order production, custom blends and contract manufacturing runs take 3–5 weeks depending on the dose form and component lead times. Samples usually go out within 48 hours.

Yes, and it is the most reliable way to start. Send the specification sheet, target assay, mesh requirement and any Certificate of Analysis from your current supplier. We will confirm in writing whether we can meet it, propose the closest achievable alternative if we cannot, and send a sample against the agreed spec.
