We have three kits available to the measurement of Dietary Fiber, These are K-TDFR, K-RINTDF and K-INTDF. 


It is possible with each kit to analyse Soluble and Insoluble (Crude) dietary fiber.

We recommend the use of the Rapid Integrated Total Dietary Fiber Assay kit (K-RINTDF) as this it is the most up to date method and better represents physiological conditions. 

Please see the links below to our dietary fiber portal which gives more information about these.
