Project Description
Product Description
Levodopais a naturally occurring amino acid and the direct metabolic precursor to dopamine. Our product is derived from the seeds of Mucuna pruriens (velvet bean), a natural botanical source. However, for B2B pharmaceutical and nutraceutical buyers, the critical factors are purity, impurity profile, and batch-to-batch consistency — not the source alone. Our L-DOPA is manufactured under strict quality controls to meet or exceed USP/EP pharmacopoeial standards, ensuring reliable performance in finished formulations.
The product is a white to off-white crystalline powder, used as an active pharmaceutical ingredient (API) in Parkinson‘s disease treatments and as a standardized ingredient in nutraceutical formulations for dopamine support.

Benefits
It is effective to improve muscle rigidity and motor retardation, and continuous medication is also effective for tremor, salivation, postural instability and dysphagia.
- Parkinson’s disease (primary tremor paralysis).
It can reduce the symptoms of tremor paralysis, improve muscle tension and make limb activity more normal. The effect is better for patients with mild and moderate illness, and worse for severe or elderly patients. - Hepatic encephalopathy.
It can make the patient awake and improve the symptoms. Hepatic encephalopathy may be related to the abnormality of central neurotransmitter dopamine, which can improve the central function after taking it. It is also believed that levodopa can improve the tolerance of the brain to ammonia, but can not improve liver injury and liver function. - Neuralgia.
Early use can relieve neuralgia. - Hyperprolactinemia.
It can inhibit thyrotropin-releasing hormone in hypothalamus and excite prolactin release inhibitory factor, so it can reduce the secretion of prolactin, which can be used in the treatment of hyperprolactinemia and has a certain effect on galactagia. - Depilation.
The mechanism may be to increase the concentration of catecholamines from blood to tissue and promote hair growth. - Promote the growth and development of children.
It can accelerate the growth and development of children’s bones by promoting the secretion of growth hormone. Treatment of children with hypophysis.
