Raw Material & Private Label Certification Program and List

Based on the popularity of ConsumerLab.com's Product Reviews and Voluntary Certification Program, in which marketed finished products are purchased and tested by CL, suppliers of raw, bulk, and finished materials for supplements and nutritional products have requested that CL test and certify the quality of their materials — using the same tests applied in the Product Reviews.

Suppliers with materials that pass CL's tests receive a certificate and are listed below by name and ingredient. There is also a link to the criteria by which ConsumerLab.com tested the material.

The list below is continually updated. Unless otherwise indicated, the sample tested was supplied by the company.
