How does protein intake affect Parkinson’s medication efficacy?
Protein intake can greatly influence the effectiveness of Parkinson’s medication, particularly levodopa (L-DOPA)—the most common and effective therapy for the motor signs of Parkinson’s disease (PD).

???? Why This Happens:
Levodopa blocks the absorption of certain amino acids (building blocks of protein) in the small bowel and transport through the blood-brain barrier.

If one has a high-protein meal near the time that he or she takes levodopa, the drug won’t be absorbed well, or won’t be absorbed at all until some time later, lessening its capacity to manage motor symptoms.
