About this guide

Peakfinity Labs owns this guide and appears in its manufacturer rankings.

DTC Supply Desk compares supplement manufacturers for brands that sell through their own store, Amazon or a subscription program. Entries were chosen from public manufacturer pages read on November 8, 2026. We compared the launch route offered, any published minimum and its unit, formulation, filling and testing support, packaging, and handoffs to fulfillment or Amazon.

This is desk research coordinated by the publisher. No factory visits, product tests or certificate-registry checks were made. Company statements are not independent verification. The numbered order reflects fit for the stated use, not a score.
