Klaire Labs®: Serving Healthcare Professionals For More Than 47 Outstanding Years
Klaire Labs® was founded in 1969 by Claire Farr, whose primary goal was to provide nutritional support for individuals with severe food allergies and environmental sensitivities. Developing some of the very first hypoallergenic nutritional supplements available, Klaire Labs® was truly an innovator in dairy-free probiotics and vegetarian enzymes for gastrointestinal support. An unwavering commitment to hypoallergenicity, product purity, and rigorous quality control has been the hallmark of the Klaire Labs® brand for more than 47 years. And having earned a strong reputation and brand recognition in the medical community, Klaire Labs® products continue to be the choice of physicians worldwide.

In 2004, Klaire Labs® was acquired by ProThera®, Inc., a nutritionally focused healthcare company that specializes in nutraceutical formulation, research, and manufacturing. ProThera® adopted the highly respected Klaire Labs® brand as a source of probiotics, enzymes, and other specialty products. Today, Klaire Labs® maintains its commitment to product purity and hypoallergenicity, offering an extensive selection of probiotics and enzymes for support of gastrointestinal health. By working closely with clinicians and researchers in the areas of intestinal dysbiosis, immune system dysregulation, and neurodevelopmental disorders, Klaire Labs® products have been carefully designed to assist gastrointestinal, neurological, detoxification, and immune system functions.
