D-Galactose ikoreshwa cyane mubikorwa bya farumasi, ibiribwa no kwisiga.Mu nganda zimiti, zikunze gukoreshwa nkibintu byangiza imiti itandukanye kandi nkibigize itangazamakuru ryumuco.Azwiho ubushobozi bwo kuzamura ituze no kunoza ubushobozi bwibikoresho bya farumasi bikora.Byongeye kandi, D-galactose ikoreshwa muri laboratoire yubushakashatsi kugirango yige imikurire ya selile, metabolism, hamwe na glycosylation.
Mu nganda zibiribwa, D-galactose irashobora gukoreshwa nkibiryo bisanzwe kandi byongera uburyohe.Ikoreshwa mugukora ibirungo, ibinyobwa nibikomoka ku mata.Uburyohe budasanzwe, bufatanije na karori nkeya, bituma busimburwa neza kubakeneye isukari iyindi.Byongeye kandi, D-galactose yasanze ifite imiterere ya prebiotic iteza imbere gukura kwa bagiteri zifata igifu kandi zifasha ubuzima bwigifu.
