A high protein intake interferes with optimal levels of L-dopa due to competition for protein carriers.

Question

Quizplus · Accepted Answer

L-dopa uptake in the brain relies on the same protein transporters that also transport large neutral amino acids, such as those found in dietary protein. As a result, a high protein intake can compete with L-dopa for these transporters and interfere with the optimal levels of L-dopa in the brain. It is recommended to take L-dopa supplements on an empty stomach or with a low protein meal to minimize this interference.
