L-DOPA otherwise known as levodopa or l-3,4-dihydroxyphenylalanine is the active compound contained in the beans from the velvet bean plant (Mucuna pruriens). As a herbal medicine it is commonly been used as an aphrodisiac, cure for male infertility, mental disorders and in Parkinson’s disease.
L-DOPA itself is an amino acid manufactured by the brain which is a precursor to the critical neurotransmitters dopamine, epinephrine and norepinephrine. L-DOPA is sold as a prescription in the United States for the treatment of Parkinson’s disease. However it can be purchased as a supplement in the form of Mucuna pruriens extract.
L-DOPA from Mucuna pruriens is included in Rejuvenation Support by Beyond Vita®.
1. Growth Hormone
Human growth hormone also known as HGH has a number of effects on the body including healing, regeneration, fat loss and increasing muscular strength.
L-DOPA through it’s action on stimulating the release of hypothalamic growth hormone-releasing hormone can increase the production of growth hormone by the pituitary.1
In a study on the effects of L-DOPA on growth hormone levels, researchers found that L-DOPA supplementation can raise growth hormone levels. The researchers also found that pretreatment with a growth hormone releasing hormone made L-DOPA ineffective which further supports that L-DOPA cause an increase in growth hormone releasing hormone itself.2
L-DOPA promotes the production of growth hormone.
L-DOPA can increase the production of testosterone through raising dopamine levels. When dopamine levels are elevated prolactin is inhibited and prolactin suppresses the production of testosterone.3
In a 2009 study on infertile men, L-DOPA supplementation significantly raised testosterone levels. Sperm count and motility were also significantly increased as well.4
L-DOPA helps increase testosterone levels by inhibiting the production of prolactin.
3. Libido and Sexual Function
L-DOPA also may be able to improve libido and sexual function.
In a study involving 7 males with Parkinson’s disease researchers found increased libido with L-DOPA treatment.5
In another study with impotent males L-DOPA improved nocturnal erections and increased libido in some of the participants.6
L-DOPA supplementation may be able to improve libido and sexual function.
4. Parkinson’s Disease
L-DOPA is sold as a prescription medication for the treatment of Parkinson’s disease. However Mucuna pruriens extract is standardized to contain L-DOPA so this extract could be beneficial.7
A double blind clinical study on a Mucuna pruriens extract containing L-DOPA and Parkinson’s disease found the herbal extract was effective and researchers noted the natural source may have advantages over current L-DOPA preparations.8
L-DOPA from Mucuna pruriens extract may be beneficial for Parkinson’s disease.
L-DOPA is an important amino acid that may help increase HGH production and raise testosterone in addition to other benefits.*
