The creatine transporter needs three charged particles—two sodiums and one chloride—to work, and they fit into specific spots on the protein that help pull creatine into the cell.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Definitive consensus on the stoichiometry and coordination of ions in hCRT across experimental systems.
A systematic review of all functional and structural studies on hCRT ion dependence, synthesizing data on Na+/Cl− requirements and binding sites.
Not applicable—RCTs cannot determine ion coordination in proteins.
Not applicable. Ion coordination is determined by structural biology.
Association between electrolyte imbalances and CCDS1 severity.
A prospective cohort of 100 CCDS1 patients, tracking serum Na+/Cl− levels and correlating with neurodevelopmental outcomes.
Association between hCRT mutations and serum electrolyte levels.
A cross-sectional study of 50 CCDS1 patients, measuring serum Na+, Cl−, and creatine, and correlating with mutation location in ion-binding sites.
Hypothetical models of ion binding based on analogy to other symporters.
A review article proposing ion coordination in hCRT based on LeuT or DAT structures.
