Drugs and their metabolites, natural extracts, and cosmetics can have antioxidant properties by helping living organisms defend themselves against oxidative stress. The KRL™ biological test provides a clear answer to the actual antioxidant capabilities of these products.

Food provides the body with numerous antioxidant substances such as vitamins A, C, E, trace elements, carotenoids, polyphenols, ubiquinone, etc. Knowing the real effectiveness of these substances in helping the body effectively fight oxidative stress allows us to choose the foods, drinks and food supplements that are most beneficial for our well-being and health. The KRL™ biological test provides a clear answer on the real antioxidant capacities of these products.


The KRL™ biological test is an in-vitro diagnostic medical device for measuring, on whole blood and on packed red blood cells, the overall antioxidant defense capacity of an individual (human, animal). It can be carried out in the context of preventive medicine ( population monitoring ), nutritional monitoring or therapeutic monitoring (prognostic test) .
The KRL™ biological test can also be used, in the context of clinical or preclinical studies, to measure the overall antioxidant (or pro-oxidant) defense potential of a product (food supplement, food or drink, etc.) or a lifestyle (psychological stress, sedentary lifestyle, smoking, etc.), both in humans and in animals (livestock, livestock, sports, pets).
