Mucuna Pruriens L-Dopa Capsules

Mucuna Pruriens, or Velvet Bean, is a bean that grows from vines and is very itchy to touch due to serotonin on its surface. It is a good source of L-DOPA, and contains some other molecules that may aid the benefits of L-DOPA. The other psychoactives in Mucuna are dosed too low to be relevant.

Mucuna L-Dopa 15% Capsules

Mucuna pruriens is a legume known as “velvet bean” or “Cowhage” containing a phenolic compound in the seeds, L-Dopa (1).

Mucuna Pruriens (L-Dopa 15%) Capsules Mode of Action

Mucuna belongs to the sub-family Papilionaceae which includes 150 species of legumes.  Mucuna is indigenous to tropical and sub-tropical areas and is regarded as a food source due to its viable proteins and digestibility.  It was widely cultivated in eastern India and southern China and is cultivated for food use in Africa, Asia, America, and the Pacific Islands (1).

“Cowitch” and “cowhage” are the names the English gave to Mucuna for the species that have long hairs on the pod which cause stinging and itching by mucunain.  The other species of Mucuna that have silky hairs which do not sting are known as “velvet bean” (1).

Mucuna’s seeds contain L-Dopa which is a precursor to the neurotransmitter dopamine (1).   L-Dopa, or Levodopa, is the main constituent of Mucuna, along with nicotinic acid, serotonin and the precursor 5-HTP, tetrahydroisoquinoline alkaloids, bufotenine, beta-carboline, mucunain (which causes itching when it comes into contact with skin), behenic acid, CoQ10, NADH (nicotine adenine dinucleotide), Inositol (D-chiro inositol and myo-inositol), selenium, iron, magnesium, and other saponins, flavonoids, anthraquinones, terpenoides, cardiac glycosides, and tannins (2).

Mature seeds contain between 3-12.5% L-Dopa, and the leaves contain only 0.5%(2).  L-Dopa is a direct precursor of dopamine and can also be directly synthesized from the non-essential amino acid tyrosine, or indirectly from acidphnylalanine, an essential amino acid.  Both amino acids are found in protein and tyrosine is the most abundant in food sources (3).

L-Dopa synthesizes dopamine in the body after ingestion through a rapid conversion in the peripheral tissue (2).  Dopamine is a neurotransmitter which functions in a neuromodulatory system known as the dopamine system, consisting of dopaminergic pathways and cell groups.  Dopamine is involved in motor control, executive functions, reinforcement and reward, motivation, and arousal.  Other functions it influences include nausea, lacatation, and sexual gratification. Dopamine is also involved in some aspects of pleasure-related cognition (3).

Dopamine circulating in the bloodstream is small and can be produced by the digestive system or sympathetic nervous system.  Dopamine receptors in the peripheral tissues may receive the dopamine or it can be metabolized and converted in norepinephrine and then released by the adrenal glands (3).

How to Take

Recommended dosage, active amounts, other details

Supplement-wise, 5g of Mucuna Prurients dried powder has been used with efficacy in some human studies on Parkinson’s Disease and Fertility. This dose or doses upwards of it should be a good starting point.

If your supplement is standardized for L-DOPA and you are supplementing for an effect attributed to L-DOPA, then start with about 1/2 the L-DOPA equivalent and work up if needed (this is due to the same amount of L-DOPA in Mucuna being more bioactive relative to isolated L-DOPA without carbidopa).

Mucuna Pruriens can be eaten isolated as a food product, but cooking is required to destroy trypsin inhibitors in the beans (so protein absorption is not hindered) yet cooking also destroys L-DOPA.

Some supplements use the cotyledon of Mucuna Pruriens, which may have different nutrient profiles relative to the bean or whole root.

 Caution Notice

Mucuna Pruriens contains L-DOPA, also known as Levodopa. This is a dopamine precursor and sometimes used as a pharmaceutical to treat Parkinson’s Disease (alongside another compound known as Carbidopa)

Compounds contraindicated with Levodopa/Carbidopa treatment most likely extend to Mucuna Pruriens and should be approached with caution. This appears to be narrow-eye glaucoma suffers, those using pharmaceutical MAO inhibitors, and those who have a history of melanoma or suspicious and undiagnosed skin lesions.
