AttoSil bentonite nanoclay binds toxins with high affinity and high capacity. Montmorillonite has been shown to be the active ingredient in bentonites. The proposed mechanism of action of AttoSil bentonite clay is through the adsorption of toxins (mainly onto the interlayer spaces of montmorillonite). Bentonite clay is a common anti-caking agent in animal feeds to adsorb aflatoxins and diminish their bioavailability. Application may include adding into mineral premix and feeds.
