Probiotic Testing for dietary supplements involves analyzing product samples using validated scientific methods to verify safety, purity, potency, and regulatory compliance. Accredited labs like Qalitex use instrumentation such as HPLC, ICP-MS, and microbiology assays to generate Certificates of Analysis (COA) required by FDA, Amazon, and retail partners.
FDA Alert: Probiotic Products Fail to Meet Label Claims for CFU Count
A review of popular probiotic products found that over 40% failed to meet the advertised CFU count at expiration, highlighting the critical importance of independent potency and viability testing.
Dietary supplements brands require specialized testing to ensure product safety, regulatory compliance, and consumer trust. Qalitex Laboratories provides probiotic testing specifically designed for the dietary supplements industry. Probiotic products require specialized testing to validate that the claimed strains are present, viable, and at the labeled potency at both manufacture and throughout shelf life. Qalitex Laboratories provides ISO 17025 accredited probiotic testing using culture-based and molecular methods to deliver accurate, defensible results. Our testing protocols are calibrated to the unique requirements of dietary supplements products, from raw material verification to finished goods release testing.
Probiotic Testing Tailored for Dietary supplements
The dietary supplements industry has specific testing requirements driven by FDA regulations, marketplace compliance (Amazon, retail), and consumer safety expectations. Qalitex designs testing panels specifically for dietary supplements products, ensuring you meet all applicable standards while optimizing your testing budget. Our scientists understand the unique matrices and formulation challenges of dietary supplements products.
Probiotic Enumeration
We perform total viable count (TVC) and species-specific enumeration for commonly used probiotic strains including Lactobacillus, Bifidobacterium, Streptococcus, and Saccharomyces. Results are reported in CFU/g or CFU per serving as required for label compliance.
Strain Identification
We use 16S rRNA sequencing and culture-based identification to confirm strain identity at the species level. Essential for brands making specific strain claims on labels (e.g., Lactobacillus acidophilus NCFM).
Probiotic Stability Testing
Probiotic viability decreases over time. Our stability studies test products at defined intervals to establish accurate expiration dating, ensuring your potency claim is valid at end of shelf life — as required by NPA, USP, and industry standards.

常见问题解答
What probiotic testing do dietary supplements brands need?
Dietary supplements brands typically require identity testing, purity analysis, contaminant screening (heavy metals, pesticides, microbiology), and potency verification. Specific requirements depend on the product type, target market, and applicable regulations (FDA, FTC, state laws).
Do you provide COA reports for dietary supplements products?
Yes. Every test at Qalitex generates a detailed Certificate of Analysis (COA) that includes test methods, results, specifications, and pass/fail determinations. Our COAs are accepted by FDA, Amazon, retailers, and international regulatory bodies.
Is Qalitex Laboratories ISO 17025 accredited?
Yes. Qalitex Laboratories holds ISO/IEC 17025 accreditation, the international standard for testing and calibration laboratories. This ensures our methods, equipment, and quality systems meet the highest standards of accuracy and reliability.
What is your turnaround time?
Standard turnaround is 5–7 business days. Rush service with 48-hour turnaround is available for most test types. Contact us to discuss your timeline requirements.
What types of products do you test?
Qalitex tests dietary supplements (capsules, powders, gummies, liquids), cosmetics and personal care products, food and beverage items, botanical extracts, and raw materials. We serve brands, contract manufacturers, and Amazon FBA sellers.
How do I submit samples for testing?
Ship your samples to our Irvine or San Diego laboratory with a completed sample submission form. We provide prepaid shipping labels for qualifying orders. Results are delivered electronically via secure portal.
How are probiotic CFU counts measured?
Probiotic CFU (Colony-Forming Units) are measured through culture-based enumeration methods that count viable organisms. Qalitex performs total viable count and species-specific enumeration for Lactobacillus, Bifidobacterium, Streptococcus, and Saccharomyces strains.
