Nichi GLOW is one of the brands in the Nichi Glucan range of food supplements, a produce of AFO-202 strain of Aureobasidium Pullulans, a yeast, Which comes in a box of 30 sachet (each 1.0 gram of granule; 21mg Beta 1,3-1,6 glucan/gram). Contains none of the 28 ingredients, notified in the list of commonly known allergens.


Clinical study of Nichi Glow in children with autism spectrum disorders (ASD) after consumption for 90 days helped in improvement of behaviour and sleep with corresponding increase in serum Alpha-Synuclein levels and endogenous melatonin. When the fecal gut microbiome was evaluated, a significantly beneficial reconstitution was observed, proving that the Nichi GLOW B-glucans addressing one of the root causes, i.e., the gut dysbiosis.












Alpha-synuclein is a presynaptic neurotransmitter that plays a key role in the synaptic functions of neurons. The gut-microbiota axis is the connecting link wherein Gram-negative enteric bacteria such as the Enterobacter and Escherichia coli secrete the pathological curli proteins and amyloids that cause abnormal misfolding of Alpha-Synuclein, whose accumulation in the gut nervous system plays a major role in the pathogenesis and progression of the neurodevelopmental disorders such as ASD and in future may cause neurodegenerative diseases through the gut-brain-axis.


In the clinical study, consumption of Nichi Glow regulated bowel movement as reported subjectively and the metagenome evaluation of the fecal gut microbiome, revealed a beneficial reconstitution, especially a significant decrease in Enterobacteriaceae and E. Coli thus, demonstrating the health benefits of this Nichi Glow supplementation in ASD.
