Clinical effectiveness of probiotic organisms is dependent on many variables. Identification and selection of appropriate, documented probiotic species as well as maintenance of maximum viability throughout all stages of handling is central to expression of the full potential of beneficial flora. Klaire Labs’ probiotic quality assurance commitment consists of an aggressive, independent testing program that monitors and ensures the identity, activity, and hypoallergenicity of our finished products.

Clinically documented effectiveness.
Probiotic species used in our formulations have been researched, genetically documented, and representative microorganisms have been banked in recognized microbial culture collections.

Human-compatible species of Lactobacillus, Bifidobacterium, Saccharomyces, and other beneficial flora
Colonizing and transient species with documented benefit

Genetic Identification by RNA Ribotyping

Ribotyping is a highly reproducible, precise diagnostic genetic fingerprint that identifies and classifies bacteria based upon differences in ribosomal RNA. This method establishes the authenticity of probiotic microorganisms by comparing them to strains documented in the literature to possess a specific genetic makeup or pattern. Strains used in Klaire Labs’ probiotic formulations have undergone ribotyping to validate the specific genetic pattern in comparison to established, documented strains.

Vegetarian, dairy free.

Cow’s milk allergy is one of the most common food allergies in infants and children. Evidence suggests that probiotics cultured using dairy products may be associated with an increased risk of developing sensitivity to cow’s milk. Ensuring the absence of dairy proteins in probiotic supplements is a difficult task, as almost all commonly available probiotic materials are grown on dairy-containing media.

Klaire Labs’ probiotic bacteria are specially cultured on a proprietary, vegetarian growth media to help ensure maximum tolerance and absence of dairy proteins.

Viability and purity independently verified.

Probiotics are highly sensitive to handling, transport, and storage. Our rigorous testing program monitors stability throughout all manufacturing stages. Upon receipt, all probiotic raw materials undergo independent laboratory analysis for verification of purity and stated potency prior to use in manufacturing.

Humidity and Temperature Monitoring.
Moisture and heat are enemies of probiotic viability. Our probiotic formulations are manufactured and packaged at a GMP-compliant facility, where filtered air systems and a humidity and temperature-monitored environment help ensure product stability and purity at this critical stage of handling.

Verification of purity and potency.

To ensure that manufacturing and packaging processes do not adversely affect potency, all Klaire Labs® finished probiotic products are independently tested prior to release. Probiotic enumeration, microbial content, and coliform content are evaluated on each batch to ensure quality of the final product.

Highly sensitive Neogen® Veratox assay.

Each finished batch of Klaire Labs’ probiotics is analyzed using Neogen® Veratox testing, a highly sensitive technique that detects levels as low as 0.00025% (<2.5 ppm) of milk allergens such as casein. Other methods commonly employed in the industry have higher detection levels of 0.1% (1,000 ppm) and may inaccurately report absence of dairy even though it is present. Dairy-sensitive individuals can use Klaire Labs’ probiotics with confidence.

Refrigerated storage and shipping.
Routine inclusion of higher quantities of microorganisms than stated on our labels coupled with refrigerated storage and temperature-control packs ensure that our probiotics, when properly stored and refrigerated, will retain their stated potency for at least one year from the date of manufacture. Shelf-life is confirmed by stability testing.
