LENTIN PLUS 1000 is a functional food manufactured using a water-soluble rice bran dietary fiber component (hemicellulose B). Collaborative research with Prof. Mamdooh Ghoneum Ph.D. at the University of California, Los Angeles, USA (UCLA/Drew University of Medicine and Science) on rice bran dietary fiber components has led to the discovery and establishment of processing and manufacturing methods of a food that optimally modulates the innate immune function of the body. It was subsequently demonstrated that LENTIN PLUS 1000 has not only an immunostimulatory effect but also an immunomodulating effect. It is now distributed to more than 50 countries worldwide, mostly through health practitioners.
