Yes, creatine use can cause dizziness in rare cases, usually tied to big doses, poor hydration, or stimulant blends.

No, current evidence shows creatine does not cause erectile dysfunction; research finds no direct link between creatine and erections.

No, creatine doesn’t reduce true GFR; it can lower creatinine-based eGFR by raising blood creatinine without harming kidneys.
