Cambridge Nutritional Sciences plc Cambridge Nutritional Sciences plc (AIM: CNSL) is a United Kingdom-based specialist medical diagnostics company that develops, manufactures, and distributes products focused on food sensitivity testing and gut health diagnostics; its core offerings include FoodPrint kits for detecting immune reactions to food via IgG antibody testing, the point-of-care Food Detective self-test kits, CNSLab functional testing services for healthcare professionals and consumers, the My Health Tracker app for symptom tracking and result management, and the newly launched Gut Detective stool biomarker panel assessing gut inflammation, enzyme production, and permeability. The company operates globally across more than 75 countries, serving over 170 laboratories, private clinics, nutritionists, naturopaths, and functional medicine practitioners in regions including the UK, Europe, North America, India, Asia, Africa, and the Middle East. Founded in 2004 and headquartered at Eden Research Park, Henry Crabb Road, Littleport, Cambridge, United Kingdom, the company rebranded from Omega Diagnostics Group PLC in September 2023 to emphasize its nutritional sciences focus. In recent developments, Cambridge Nutritional Sciences completed a sales team restructure in 2025 to separate customer acquisition, service, and success functions aimed at accelerating new distributor and laboratory signings amid slower sales cycles in Europe and the Americas; it launched the CE-marked Gut Detective product in August 2025 exclusively for the UK practitioner market initially; operational enhancements drove gross margins to 67.7% for the six months ended 30 September 2025 through improved FoodPrint production yields and product mix, despite a 6% revenue decline to £3.9 million; and the company invested in new manufacturing machinery, a Laboratory Information Management System upgrade, IVDR compliance development, and website enhancements while suspending new My Health Tracker app onboarding.
