Probiotic Testing for quality control ensures products meet the specific regulatory and quality standards required for market entry. ISO 17025 accredited laboratories like Qalitex provide validated testing methods, detailed COA reports, and expert guidance to support quality control processes efficiently.
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.
Achieving quality control requires accurate, accredited laboratory testing that regulatory bodies and marketplace platforms trust. Qalitex Laboratories provides probiotic testing tailored for quality control requirements. 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 ISO 17025 accredited methods and detailed COA reports are designed to streamline your quality control process.
How Probiotic Testing Supports Quality control
Quality control requires documented evidence of product safety and quality. Qalitex provides the specific testing and documentation needed to support your quality control process, including detailed COA reports, method validation documentation, and expert consultation on testing scope. Our ISO 17025 accreditation ensures your results are accepted by regulatory bodies and marketplace platforms.
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.
