Dietary Supplement Testing to Meet U.S. FDA Requirements 

When you receive a dietary supplement component or raw material into your facility, you need to be confident that it’s exactly what you ordered. Current Good Manufacturing Practices (cGMPs) outlined in U.S. FDA regulations (21 CFR 111) require… 

$

Verification that the 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. Our supplement lab testing confirms identity, purity, strength, composition, and the absence of potential contaminants, per U.S. FDA regulations in 21 CFR 111. 

IDENTITY

FDA cGMPsrequire 100% identity testing for all dietary ingredients, raw materials, and finished products to confirm identity and determine whether other specifications for components are met.

PURITY

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 supplement purity testing.  

STRENGTH

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. 

COMPOSITION

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.  

CONTAMINANTS

Dietary supplements must be tested to ensure they are free from harmful contaminants like pathogens, pesticides, heavy metals, and residual solvents. Contaminant levels must meet FDA safety limits to prevent adulteration and protect consumer health.

Supplement Testing to Meet Amazon Requirements

In addition to testing to help you meet U.S. FDA requirements, our supplement testing labs also conduct most of the tests required to sell your supplements on Amazon, including contaminant screening for heavy metals, microbial contaminants, and other analytes. We can also perform the testing required to verify product content claims and develop your Supplement Facts Panel.
