Mucuna Pruriens, more commonly known as Velvet Bean or Cowitch, is a tropical bean that contains phenomenal levels of a substance called levodopa, or L-DOPA. Levodopa is the direct precursor to Dopamine, Norepinephrine, and Epinephrine, typically synthesized in the body from the amino acid tyrosine.
Levodopa is unique in that it can cross the blood-brain barrier whereas dopamine itself cannot; once in the brain it's then converted into a reserve of usable dopamine (and the other neurotransmitters as well).
Reading up on Wikpedia and elsewhere, I read enough things about dopamine / L-DOPA (its precursor, after all) to see if supplementation with Mucuna Pruriens might do anything for me. My interest is triple-pronged:
1. Dopamine levels in the brain appear to be related to motivational behavior; in test subjects (rats) low dopamine levels result in unmotivated, lazy, apathetic creatures. In extreme cases they even lacked the willpower to move themselves to a food dish to eat, despite obvious signs of hunger. This interests me because I have been suffering for some time from what I like to call (half-jokingly) "extreme apathy(! ," where at times even things like walking to a dining hall or playing a game feel like immense wastes of time that couldn't possibly have any benefit. My enjoyment of these activities doesn't diminish, but the drive to do them does. I'd like to see if artificially pumping my dopamine levels has any effect on this.
2. Increasing dopamine levels in the brain appears to be a useful tactic for fighting Parkinson's disease. This interests me because while I don't have Parkinson's (lucky me), I do have a benign essential tremor in my hands that destroys my ability to perform fine motor movements with any sort of grace (my writing is chicken scratch, my lines are zigzags, my circles are... let's not get into it). I have irrational hope that if pumping up dopamine levels can decrease the impact of Parkinson's, that it can have an impact on other sorts of tremors as well.
3. What you're all interested in: Dopamine plays a role in proper sleep and dreaming. People with Parkinson's (low dopamine, remember) typically exhibit signs of sleep disorder to some extent or another. Lab results on rats at least do show that animals with severely reduced dopamine levels are unable to sleep, and that increased brain levels of the neurotransmitter showed, as seen under brain scan, brain patterns mimicking those of REM sleep and the dream state, even in wakefulness. Schizophrenics and psychotics (Who have too much dopamine, all the time) are thought to experience their hallucinations and delusions because of their heightened levels of dopamine. And finally, well, Wikipedia mentions that one of the "side-effects" of taking L-DOPA is "vivid dreams."
All this under consideration, I placed an order for a bottle of 60 500mg capsules of Mucuna Pruriens (w/ ~40mg levodopa per pill), and it should be here around next monday/tuesday.
Stay tuned...!
