Pathway
Taken up by muscle and brain; converted to phosphocreatine; spontaneously degraded to creatinine
Elimination
Urine (as creatinine)
Important Nuances
Plasma half-life reflects clearance from blood into tissue stores; cognitive effects are from maintained brain phosphocreatine levels, not plasma concentration. Loading phase (20g/day for 5 days) is optional; 3–5g/day maintenance is sufficient.
