Probiotic Testing Laboratory Services for Dietary Supplements & Nutraceuticals

Accurate CFU Count, Strain ID, Contamination & Stability Testing for Supplements and Functional Products

 

At Qalitex, our state-of-the-art probiotic testing laboratory provides scientifically rigorous analysis for dietary supplements, functional foods, and nutraceuticals. Whether you’re launching a new probiotic capsule, formulating a multi-strain symbiotic, or verifying the CFU count on a commercial yogurt product, we deliver fast, accurate, and regulatory-compliant probiotic testing.

As industry experts in microbiological analysis and stability testing, we help brands validate probiotic strain identity, potency (CFU), shelf life, and contamination risk—all essential for label claims, safety, and consumer trust.


Why Probiotic Testing Matters

Probiotics are living organisms. Their viability and effectiveness depend on proper formulation, packaging, and storage. Regulatory bodies like the FDA, Health Canada, and EFSA require accurate probiotic labeling and safety validation. Without routine testing, your product may:

  • Contain fewer CFUs than claimed

  • Lose potency before expiration

  • Be contaminated with pathogens or spoilage organisms

  • Contain mislabeled or undeclared strains

Our laboratory helps you stay ahead of compliance requirements and build a credible, science-backed brand.
