Natrix Srl was founded in year 2000 in Reggio Emilia (Italy) as a laboratory for analysis, and developed the innovative Food Intolerance Test to detect the so-called 'food intolerances', or adverse reactions to foods mediated by IgG antibodies. Over the years, Natrix concentrated their studies on the aging and in particular on the oxidative stress of the cell (Antiaging Profile), then lipidomics, launching the Lipidomic Profile, a method to detect the lipid imbalance. From our extensive experience in the diagnostics, then we developed the Cardio Wellness Profile, the Zone Plus Test and the Cellular Aging Factors, which analyzes specific biomarkers to draw a profile of cellular aging. The latest addition is the Gluten Sensitivity Test, one of the first diagnostic tools in Italy to detect the non-celiac gluten sensitivity. To complete the diagnostics part, Natrix has developed Telenutrizione, an online web based platform that allows patients to follow, in direct contact with the nutritionist, dietary protocols of various types, including diets for the recovery of tolerance.
