As the average age of population increases, memory impairment has become an increasingly prevalent issue. This study investigates effects 14 days oral birch sap administration on functions in healthy rats using Morris water maze (MWM) test and explores underlying mechanisms. A compositional analysis revealed that soap is rich polysaccharides, specifically a low-molecular weight polysaccharide (MW 1.29 kDa), exhibits no hepatotoxicity or renal toxicity at tested dose. The results from MWM demonstrated time distance required to reach platform were significantly shorter sap-treated group compared control group, suggesting supports preservation. Moreover, treated with showed improved cerebral blood flow rats. Additionally, hippocampal nerve terminals (synaptosomes), exhibited significant increase evoked glutamate release, as well elevated levels presynaptic proteins, including vesicular transporter 1 (VGluT1), synaptophysin, synaptobrevin, synaptotagmin, syntaxin, synapsin I, 25 kDa synaptosome-associated protein (SNAP-25). Transmission electron microscopy also notable number synaptic vesicles synaptosomes birch-sap-treated These findings suggest enhances glutamatergic flow, contributing its memory-preserving
