%X <B>BACKGROUND: </B>Several studies indicate that changes in cerebrospinal fluid (CSF) composition depend on the disease stage and reflect modification of brain energy metabolism (BEM). Also, it has been reported that a decline in cognitive functions may be mitigated by incorporating nutraceuticals in the diet.<BR><B>OBJECTIVE: </B>Assuming the beneficial effect of nutraceuticals on BEM and oxidative damage, the aim of this study was to determine if the administration of a nutraceutical compound results in changes of select CSF biomarkers in healthy adult Beagle dogs.<BR><B>METHODS: </B>Two separate CSF and blood samples were obtained from 11 healthy adult Beagle dogs, before and after 50 days of treatment with a veterinary combined nutraceutical. CSF analysis included a total nucleated cell count, total protein, glucose, sodium, chloride, potassium, pyruvate, and lactate concentrations, and calculation of lactate/pyruvate ratio. CBC and serum biochemistry were also performed. The Wilcoxon test was used to analyze the significance of the changes after nutraceutical treatment.<BR><B>RESULTS: </B>All studied variables remained within reference intervals, before and after treatment. A significant increase in CSF sodium and glucose concentration, and a decrease in lactate levels, was observed after treatment (P < .05), and the lactate/pyruvate ratio was decreased after treatment (P = .05). In serum, sodium and chloride concentrations were significantly increased (P < .05), and creatinine concentration was significantly decreased (P < .05) after treatment.<BR><B>CONCLUSIONS: </B>After 50 days of treatment with a nutraceutical compound, CSF glucose, sodium, and lactate concentrations, and L/P ratio were significantly different, suggesting an influence of nutraceuticals' administration on CSF composition.
