Processes are described for the production of an isolated medicinal composition for administration to mammals which comprises an effective amount of a free acid, salt or chelate of at least one naturally occurring form of an alpha hydroxyl organic acid comprising combining at least one naturally occurring form of an alpha hydroxy organic acid with an amount of base in an aqueous solution, wherein a total content of alpha hydroxyl organic acids amounts to between about 0.5% and about 35% w/w of the solution, for a time to hydrolyse substantially all forms of alpha hydroxyl organic acids present, neutralizing the solution to a pH between about 6.9 and about 7.6 to yield a free acid, salt or chelate of free acids of substantially all naturally occurring forms of alpha hydroxyl organic acids, and optionally lyophilizing the solution to produce an isolated medicinal composition. Compositions produced by these processes are disclosed and claimed. Method are described of enhancing DNA repair, enhancing an immune response, controlling inflammation, or inhibiting the progress of a tumor, comprising administering an effective amount of a composition produced by the processes described herein.Cette invention concerne des processus de production dune composition médicinale isolée destinée à être administrée à des mammifères et comprenant une quantité efficace dun acide libre, dun sel ou dun chélate dau moins une forme naturelle dun acide organique alpha hydroxyle, lesquels processus consistent à combiner au moins une forme naturelle dun acide organique alpha hydroxyle à une quantité de base dans une solution aqueuse, une teneur totale en acides organiques alpha hydroxyle représentant entre environ 0,5 % et environ 35 % en poids de la solution, pendant une durée permettant dhydrolyser substantiellement toutes les formes dacides organiques alpha hydroxyle présentes, à neutraliser la solution à un pH compris entre environ 6,9 et environ 7,6 pour produire un acide libre, un sel ou
