Probiotic Testing in California is available through ISO 17025 accredited laboratories like Qalitex Labs, which operates facilities in Irvine and San Diego, California. These labs use validated analytical methods including HPLC, ICP-MS, and GC-MS to test dietary supplements, cosmetics, and food products for safety, purity, and regulatory compliance.
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.
Qalitex Laboratories provides ISO 17025 accredited probiotic testing services to brands in California and throughout the United States. 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 California-area clients benefit from proximity to our Southern California labs, enabling faster sample delivery and turnaround times as quick as 48 hours.
Why Choose Qalitex for Probiotic Testing in California
Qalitex Laboratories is one of the leading ISO 17025 accredited testing labs in Southern California, with facilities in both Irvine and San Diego. Our proximity to major California shipping hubs means faster sample receipt and quicker results. We combine state-of-the-art instrumentation (HPLC, ICP-MS, GC-MS, LC-MS/MS) with experienced scientists to deliver accurate, regulatory-ready results.
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.
