Background/Objectives: Drinking natural bicarbonate water (NBW) has been associated with decreased bone resorption, improved lipid profile, and reduced cardiovascular risk. However, the specific molecular mechanisms underlying these effects remain unclear. Methods: Twenty 10-month-old female Sprague Dawley rats were randomly allocated to two experimental groups; one received purified water (PW) and the other was administered NBW over a three-month intervention period. The liver’s metabolic properties were analyzed using a comprehensive quantitative targeted metabolomics technique. Results: Sixty-nine differential metabolites (67 upregulated and 2 downregulated) were detected in the NBW group compared to the PW group. These metabolites included 34 amino acids, 11 carbohydrates, 7 fatty acids, 7 short-chain fatty acids (SCFAs), and 10 other biomolecules. Furthermore, 10 metabolic pathways exhibited significant alterations: aminoacyl-tRNA biosynthesis; alanine-aspartate-glutamate metabolism; nitrogen-butanoate metabolism; histidine-phenylalanine metabolism; arginine-proline metabolism; glycine-serine-threonine metabolism; valine-leucine-isoleucine biosynthesis; and phenylalanine-tyrosine-tryptophan biosynthesis. The NBW group demonstrated a statistical tendency toward lower urinary calcium/creatinine ratio compared to the PW group. Conclusions: These findings suggest that the consumption of NBW may induce positive nitrogen balance, enhance the level of certain polyunsaturated fatty acids and SCFAs, and improve calcium balance. Such metabolic alterations could potentially explain the beneficial effects of NBW.
