L-dopa is a precursor of dopamine and is converted into dopamine in the brain, thus increasing the amount of dopamine available in the brain. Dopamine is a neurotransmitter that is responsible for controlling movement, and its deficiency is the underlying cause of Parkinson's disease. Therefore, increasing dopamine levels through L-dopa helps control the symptoms of Parkinson's disease.
