l-DOPA, also known as l-3,4-dihydroxyphenylalanine and used medically as levodopa, is made and used as part of the normal biology of some plants [2] and animals, including humans. Humans, as well as a portion of the other animals that utilize l -DOPA, make it via biosynthesis from the amino acid l -tyrosine .

Levodopa, also known as L-DOPA and sold under many brand names, is a dopaminergic medication which is used in the treatment of Parkinson's disease and certain other conditions like dopamine-responsive dystonia and restless legs syndrome. [3]

2023年4月17日 · Levodopa is the precursor to dopamine. Most commonly, clinicians use levodopa as a dopamine replacement agent for the treatment of Parkinson disease. It is most effectively used to control bradykinetic symptoms apparent in Parkinson disease.

2025年1月8日 · L-Dopa (also known as levodopa or L-3,4-dihydroxyphenylalanine) is a naturally occurring amino acid precursor of the neurotransmitter dopamine. It’s a medication that has U.S. Food and Drug Administration approval (since 2018) to treat Parkinson’s disease symptoms by increasing dopamine levels in the brain.

L-DOPA is a direct precursor to dopamine often synthesized in the body from L-tyrosine. As a supplement, L-DOPA is often used for enhancing cognition and well-being or as a treatment for certain diseases, such as Parkinson’s disease. This article is about the main benefits of L-DOPA, its potential side effects, the best time to take it, and more.

2021年11月3日 · What is L-DOPA (Levodopa)? L-DOPA is an amino acid derivative also known as levodopa or L-3,4-dihydroxyphenylalanine. It is naturally produced in animals and plants. In humans, it is produced from the amino acid L- tyrosine [1]. It has been the prime treatment for Parkinson’s disease since the 1960s.
