Nutraceutical Testing That Proves Your Label — and Protects Your Brand
From raw ingredient verification to finished product testing, we deliver the analytical data dietary supplement brands need to meet FDA requirements and earn consumer trust.
Comprehensive Nutraceutical Testing Panels
Everything your supplement brand needs to prove safety, purity, and label accuracy.
Microbial Safety & Pathogen Detection
FDA's cGMP regulations (21 CFR Part 111) require that every dietary supplement batch be tested for microbial contamination. Our rapid pathogen methods detect threats in your finished product before they leave your facility.
- Salmonella spp.
- E. coli (STEC)
- Listeria monocytogenes
- Staphylococcus Aureus
- Aerobic Plate Count
- Yeast & Mold
- Total Coliforms
- Bile-tolerant gram-neg.
Heavy Metals Testing (LC-MS/MS)
Consumer Reports, class-action lawsuits, and state regulations (including California Prop 65) have made heavy metals testing a non-negotiable for supplement brands. We use LC-MS/MS for the most sensitive, accurate detection available.
- Lead (Pb)
- Arsenic (As — total & inorganic)
- Cadmium (Cd)
- Mercury (Hg)
- Chromium (Cr)
- Nickel (Ni)
- California Prop 65 compliance
- USP <232>/<233> aligned
