Supplement Test Solutions to Meet Regulatory Guidance

We help you to meet Federal Regulations found in 21 CRF 111 for cGMPs, including confirmation of established specifications for identity, purity, strength, and composition. Additionally, we conduct Amazon-compliant lab testing, support your international GFSI compliance, help you create accurate supplement facts panels, facilitate Food Fraud Mitigation plans, and defend against adulteration and counterfeiting. We also support day to day testing for all your dietary supplement products, providing brand protection, validations and support. 

Certified Laboratories provides all your testing needs with competitive turnaround times. 

For a subset of finished dietary supplement batches that you identify through a sound statistical sampling plan (or for every finished batch), you must verify that your finished batch of the dietary supplement meets product specifications for identity, purity, strength, composition, and for limits on those types of contamination that may adulterate or that may lead to adulteration of the finished batch of the dietary supplement.


FDA cGMPs require 100% identity testing for all dietary ingredients and finished products to confirm the identity of components and determine whether other specifications for components are met.


Dietary supplement ingredients and finished products must be free from adulteration and contamination, including pathogens, residual solvents, heavy metals, and other contaminants as confirmed through laboratory testing. 


The strength or potency of a dietary supplement is evaluated via the concentration, weight, or measure of each dietary ingredient and for the finished product. 


Dietary supplement components include ingredients such as vitamins, minerals, herbs, amino acids, enzymes, and other ingredients, all of which must have defined specifications clearly articulated and documented in Master Manufacturing Records against which Batch Manufacturing Records will be evaluated.
