Watch out for
- Iron binds (chelates) levodopa in the gut and can cut its absorption sharply — studies measured peak levels dropping by roughly half when the two are swallowed together — which can show up as worse Parkinson's symptom control. High-dose vitamin B6 can also speed up levodopa's breakdown outside the brain when the carbidopa component is not fully protective. Pharmacists commonly advise keeping iron or a multivitamin at least 2 hours away from levodopa doses — follow the prescriber's directions, and mention any new supplement so timing can be reviewed; B6 levels are sometimes monitored on this medication, so B6 decisions belong with the prescriber.
