A method for determining a folate substance administration regime is disclosed. The method comprises: quantifying, in a sample drawn from a patient, the expression level of at least one of the genes SLC46A1, SLC19A1, FPGS, ABCC3, MTHFD1L, GGH, MTHFD1, MTFMT, and ATIC; and establishing whether the expression level is high or low. A high expression level of at least one of said genes determines that said folate substance administration regime involves the administration of [6R]-methylenetetrahydrofolate and/or a folate substance upstreams of [6R]-methylenetetrahydrofolate in the metabolic pathway. A low expression level of at least one of said genes determines that said folate substance administration regime involves the administration of [6R]-methylenetetrahydrofolate. Also disclosed is a kit for determining such a folate substance administration regime.
