Neu REFIX is one of the brands in the Nichi Glucan range of products; specifically, this is a produce of N-163 strain of Black Yeast Aureobasidium Pullulans, comes in a box of 20 sachet (each 8.0 gram of gel; 48mg Beta 1,3-1,6 glucan/Sachet)
In pre-clinical studies*, in comparative studies in healthy volunteers, and in patients with Covid-19, the N-163 strain produce has been proven to have potent anti-inflammatory and anti-fibrotic properties. Based on such advantageous outcome, a clinical study in young boys with Duchenne Muscular Dystrophy (DMD) has been completed; a longer duration study under planning, while additional validations in pre-clinical MDX mice models under progress.
