Novel L-carnitine and alkanoyl L-carnitine salts and a process for their preparation are disclosed. The salts have the general formula <IMAGE> wherein X- is an anion of acid aspartate, acid citrate, acid phosphate, acid fumarate, lactate, acid maleate, acid oxalate, acid sulphate or orotate; R is hydrogen provided that X- is other than the orotate anion, or lower alkanoyl selected among acetyl, propionyl and butyryl; and n is 1/2 if X- is orotate, and 1 if X- is one of the other anions. Since they are not hygroscopic, these salts can be easily compounded and are favorably suitable for manufacturing solid administration forms. Their aqueous solutions are less acid than those of the corresponding chlorides: consequently, these salts are also suitable for manufacturing injectable administration forms.
