Scope

Liquid Formulation Review compares manufacturers that make oral liquid supplements under a buyer's brand: private label (an existing formula with your label, sometimes called white label) and custom formulation (a formula developed for you). It covers tinctures, drops, syrups, shots and liquid multivitamins.

Method

The Guide editorial desk read each manufacturer's public website on November 8, 2026. We compared launch route, published minimums and their units, formulation, filling and testing support, packaging options and scale-up handoffs. Order reflects fit for the stated buyer, not a numeric score.

Limits

• No factory visits, sample orders or certificate-registry checks.
• Company statements are not independent verification. Minimums, lead times and certifications change; confirm them in writing.
• Nothing here is medical, dosing or regulatory advice.
