L-DOPA

L-DOPA
L-DOPA (Mucuna Pruriens) is known for improving brain health, is an antioxidant and heavy metal chelator, improves memory & cognitive function, lowers symptoms of depression, and boosts libido.  
Key Takeaways
  1. L-DOPA is a vital amino acid precursor of neurotransmitters dopamine, epinephrine, and norepinephrine synthesized in the brain from l-tyrosine.

  2. Mucuna Pruriens is a natural source of L-DOPA, used as a nootropic to enhance brain function by increasing dopamine levels.

  3. L-DOPA from Mucuna Pruriens can improve memory, cognition, mood, and overall brain health while reducing stress and acting as an antidepressant.

  4. Opt for organic Mucuna Pruriens extract with higher L-DOPA concentrations (15% – 30%) to ensure better tolerance and efficacy, avoiding synthetic versions used for Parkinson’s treatment.

  5. Nootropic use of L-DOPA is generally safe and well-tolerated, but caution is necessary to avoid tolerance and dependence issues.

See my article on all of the supplements that have been shown to help with Parkinson’s here: Best Supplements for Parkinson’s Disease

L-DOPA (levodopa, L-3,4-dihydroxyphenylalanine) is an amino acid synthesized in your brain by the amino acid l-tyrosine. L-DOPA is a precursor of several neurotransmitters including dopamine, epinephrine, and norepinephrine.

Mucuna Pruriens contains naturally occurring  L-DOPA in high concentrations. And is used as a nootropic because dopamine itself cannot cross the blood-brain barrier.

Dopamine and norepinephrine are essential for memory, cognition, and a positive mood. A lack of either of these neurotransmitters can lead to a lower mood state, loss of memory, brain fog, poor energy, and more. And if left unchecked will eventually result in neurodegenerative diseases like Parkinson’s.

L-DOPA helps:

  • Brain Health. L-DOPA helps to increase growth hormone levels in the brain. Boosting the production of neurons and glia cells affecting the formation of memories, and overall brain health.
  • Neurotransmitters. L-DOPA is a necessary precursor for your brain to make dopamine. And dopamine is then synthesized into the neurotransmitters epinephrine, and norepinephrine. Affecting cognition, learning, memory, movement, motivation and pleasure.
  • Neuroprotection. L-DOPA produces neuromelanin which is similar to the melanin pigment in your skin. In your brain they absorb toxic quinones, and chelate heavy metals like mercury and lead.

Overview

L-DOPA (levodopa, L-3,4-dihydroxyphenylalanine) is an amino acid that’s naturally synthesized in your brain by the amino acid l-tyrosine.

L-DOPA chemical structure
L-DOPA

L-DOPA is a necessary precursor to the synthesis of the neurotransmitter dopamine. Called a catecholamine, dopamine is then synthesized into the other catecholamines epinephrine (adrenaline) and norepinephrine (noradrenaline).

Unlike Dopamine, L-DOPA can cross the blood-brain barrier. This is why we supplement with L-DOPA rather than dopamine.

Mucuna Pruriens extract contains L-DOPA
Mucuna Pruriens

And for a dopamine boost, neurohackers use Mucuna Pruriens, which contains high levels of L-DOPA.[i] This legume, native to the tropical regions of India, Africa and the West Indies, and also known as velvet bean, has been used in Ayurveda medicine since 1500 B.C.

The ancients used Mucuna Pruriens to treat things like snakebite, intestinal problems, sexual issues, and a melancholy mood.

Raising levels of the neurotransmitter dopamine in your brain helps regulate mood and cognition.[ii]

Mucuna Pruriens vs. L-DOPA: What’s the Difference?

Mucuna Pruriens is an extract of the velvet bean plant that grows 3 – 18 meters in height. L-DOPA (levodopa) is usually synthetic and made in the lab.

The natural version of L-DOPA from Mucuna Pruriens is generally well-tolerated by most people. And the compounds in the plant are bio-identical to those chemicals naturally made in your body. Not so with synthetic L-DOPA.

Synthetic L-DOPA is metabolized into dopamine in your body by an enzyme called aromatic L-amino acid decarboxylase (AADC). And the majority of synthetic L-DOPA will be converted peripherally (not in the central nervous system and brain). This can cause problems.

So when used therapeutically, as in treating Parkinson’s Disease, L-DOPA is administered in combination with an inhibitor of peripheral AADC. Drugs like carbidopa (or other AADC inhibitors) ensure most of the L-DOPA is preserved for conversion to dopamine in the brain. And not the rest of your body.

This is critical for nootropic users to keep in mind. Chronic, or prolonged use of synthetic L-DOPA can lead to things like dyskinesia. This is a movement disorder where neurological discoordination results in uncontrollable, involuntary movements.[iii]

I am not telling you this to dissuade you from using L-DOPA. Stick with an extract of Mucuna Pruriens and you should be fine.

Mucuna Pruriens (L-DOPA) boosts learning and memory

How does L-DOPA Work in the Brain?

L-DOPA boosts brain health and function in several ways. But two in particular stand out.

  1. L-DOPA improves memory. It’s metabolized into dopamine in your body by an enzyme called aromatic L-amino acid decarboxylase (AADC). This increases dopamine levels in your brain.

Researchers at the University of Münster in Germany conducted a study with 40 healthy people. In this randomized double-blind study, they gave one group 100 mg of levodopa daily for 5 days. The other group took a placebo.

90 minutes later on each day, subjects were given a memory test based on vocabulary. The study found that levodopa significantly enhanced the speed, overall success, and long-term retention of novel words.[iv]

  1. L-DOPA promotes brain health. Research suggests Mucuna Pruriens protects your brain by regulating cognitive and neural functions. And even encouraging neural activity.

Researchers in India showed that Mucuna Pruriens is a potent antioxidant. They performed assays to evaluate the enzymatic and nonenzymatic antioxidants in extracts. They found high levels of flavonoids, alkaloids, tannic acids, gallic acids, quercetin equivalents, and sitosterol equivalents.[v]

All of these compounds scavenge for free radical in your brain. Free radicals are formed during normal brain activity, like the synthesis of ATP that is produced in your mitochondria.

Your brain is equipped to eliminate some of these free radicals on its own. But especially in today’s environment in which we live, your brain is overwhelmed. Free radicals cause inflammation which damages and can kill brain cells. Affecting memory, learning, recall, cognition and mood.

Mucuna Pruriens has been proven to be a very effective brain inflammation fighter. It even has the ability to chelate heavy metals like mercury and lead in brain cells. And it’s antibacterial.[vi]

Mucuna Pruriens helps your brain make naturally occurring neuronal pigments called neuromelanin’s. They’re similar to the melanin found in your skin.  And they’re often found in regions of your brain where dopamine is active.

The synthesis of neuromelanin’s in the various regions of your brain is an important protective process. The melanic component is generated through the removal of reactive/toxic quinones that would otherwise cause neurotoxicity.

This melanic component promoted by Mucuna Pruriens is what chelates and accumulates toxic, heavy metals like mercury and lead.[vii] Preventing them from damaging brain cells.

Mucuna Pruriens (L-DOPA) boosts brain health

How things go bad

As we get older, our brain chemistry and energy metabolism changes.

↓ Dopaminergic neurons are damaged or die

↓ Dopamine levels decline

↑ Stress levels increase

↓ Long-term memory and mood decline

All of these age-related changes are contributing factors to the neurodegenerative diseases of aging, including Parkinson’s Disease.

L-DOPA benefits for brain health

Mucuna Pruriens natural herbal supplement extract contains high levels of L-DOPA, the precursor to the crucial neurotransmitter dopamine. Dopamine is further synthesized into the neurotransmitters epinephrine (adrenaline) and norepinephrine (noradrenaline).

Dopamine plays a critical role in learning and absorbing new information. Increasing brain levels of dopamine helps regulate mood and boosts cognition.

Research also suggests that Mucuna Pruriens provides antioxidants that defend against oxidative damage caused by free radicals.[viii]

How does L-DOPA feel?

Neurohackers report that using Mucuna Pruriens helps in multi-tasking, improving motivation, more focus, less stress, and a sense of calm.

You could find your energy levels increase, less brain fog, and a boost in overall mood. A more positive outlook on life. And an increase in libido.

L-DOPA Clinical Research

Mucuna Pruriens reduces stress

A study was conducted to assess the role of Mucuna Pruriens in infertile men. It was done at King George’s Medical University in Lucknow, India. The study included 60 men who were undergoing infertility screening. And no surprise here; were found to be suffering from stress.Mucuna Pruriens (L-DOPA) boosts libido and sperm count

The control group in this study were 60 age-matched men who had initiated at least one pregnancy. The infertile men were given 5 grams of Mucuna Pruriens seed powder per day for 3 months. Semen samples were collected at the beginning of the study. And after 3 months of treatment.

The researchers found that treatment with Mucuna Pruriens significantly decreased stress levels. And increased sperm count to the same level as the fertile control group of men.

They “concluded that M. pruriens not only reactivates the anti-oxidant defense system of infertile men but it also helps in the management of stress and improves semen quality.”[ix]

L-DOPA improves learning

This study in Germany was done with 40 healthy subjects. They were given 100 mg of L-DOPA or a placebo for 5 days in a randomized, double-blind trial.

Subjects were trained on artificial vocabulary using a high-frequency, repetitive approach. This was done 90 minutes after L-DOPA administration on each day of the trial.

The researchers found that L-DOPA significantly enhanced the speed, overall success, and long-term retention of the words.[x]

L-DOPA as an anti-depressant

Increasing dopamine in your brain also boosts your mood and libido. This study was done in India with mice. Researchers used the well-known Forced Swimming Test (FST), Tail Suspension Test (TST), and Chronic Unpredictable Mild Stress (CUMS) test.

The mice were fed Mucuna Pruriens seed extract, and then evaluated while performing, well… what mice do in the lab.  The research team found that Mucuna Pruriens seed extract has significant antidepressant qualities. Which would simply verify what we already know in humans.[xi]

Using Mucuna Pruriens extract is a great anti-depressant.

L-DOPA Recommended Dosage

L-DOPA (Mucuna Pruriens extract) suggested dosage for cognitive benefits is 250 – 500 mg twice per day. Most Mucuna Pruriens extracts only contain 15 – 20% L-DOPA. So you may need to adjust your dose up or down depending on how you respond to this supplement.

You may also find that you need to cycle the use of L-DOPA (Mucuna Pruriens). And use it only 4 or 5 days a week. This can help avoid tolerances and dependencies (which are common with any dopamine agonist). DO NOT attempt to cycle this nootropic if you are using it to treat Parkinson’s Disease.

If you are using Mucuna Pruriens extract (L-DOPA) for Parkinson’s Disease you will likely need 500 – 1,000 mg Mucuna Pruriens 3 or more times per day. And look for a Mucuna Pruriens extract (98% L-DOPA). 

See my article on all of the supplements that have been shown to help with Parkinson’s here: Best Supplements for Parkinson’s Disease

L-DOPA Side Effects

L-DOPA is produced naturally in your body. So is considered well-tolerated and safe. And L-DOPA from Mucuna Pruriens extract is particularly well tolerated by most people.

Research shows that the natural form of L-DOPA from Mucuna Pruriens compared to synthetic versions of L-DOPA provides similar results. But without the common side effects of nausea, vomiting, and involuntary muscle movement.[xii]

But be very careful when working with dopamine. Too much and you can experience symptoms like hair loss, auditory or visual hallucinations, psychosis, Dyskinesia and more.

Of course, if you begin to experience any of these side effects, stop supplementing with L-DOPA (Mucuna Pruriens) immediately.

Like any natural supplement, it’s always better to use an organic source.

Type of Mucuna Pruriens (L-DOPA) to buy

Mucuna Pruriens is typically available in powder, capsule or tablet form. Some are pure, dried Mucuna Pruriens powder.

Several manufacturers offer Mucuna Pruriens extracts ranging from 15% – 30% L-DOPA. Or they tell you how many mg of L-DOPA is in each capsule or tablet.

A few manufacturers call it “Velvet Bean Extract” or “Mucuna Extract” with the percentage of L-DOPA in each capsule or tablet. It’s the same as Mucuna Pruriens.

Try to find “organic” or “certified organic” if you can. And for Nootropic use, avoid synthetic L-DOPA which is typically used to treat Parkinson’s Disease.

Nootropics Expert Recommendation

L-DOPA (Mucuna Pruriens) dosage 250 – 500 mg twice per day

Nootropics Expert Tested and ApprovedI recommend using L-DOPA as a nootropic supplement.

Your body does synthesize some L-DOPA on its own. And converts it into the essential neurotransmitters dopamine, epinephrine, and norepinephrine.

But as you get older, dopamine receptors die or become unresponsive. Or your body doesn’t convert the necessary amino acids well enough to supply the neurotransmitters you need for an optimized brain.

L-DOPA is helpful to boost energy and motivation levels, memory, clear brain fog, improve mood and libido.

L-DOPA is especially helpful for those suffering from neurodegenerative diseases like Parkinson’s. And the natural form of L-DOPA from Mucuna Pruriens often offers better results with fewer side effects than prescription drugs.

I suggest starting with a dose of 100 – 250 mg twice daily for nootropic use at first. And you may find that you need to cycle L-DOPA. Use it for 4 or 5 days and take a break. Tolerance is often a problem when working with dopamine. As is dependence or addiction.

    If properly used, not exceeding dosages, rotating usage, would you suggest Mucuna or L-Tyrosine, when adding to a Concerta stack(or even without), considering all their respective benefits?

    Thank you David

      Salem, L-DOPA increases dopamine which you do not want to increase at night. You need dopamine during the day. Best to use it morning and noon every single day. The days that you do not use L-DOPA are days you’ll not have optimal dopamine levels.

      Kenneth, the L-DOPA in that supplement makes dopamine. And Concerta uses dopamine receptors and transporters to do its job. You are supporting how Concerta works when using that supplement.

    There is confusion between the terms L-DOPA and mucuna pruriens throughout the comments – and throughout your article.

    L-DOPA and mucuna pruriens are not the same thing and the terms cannot be used interchangeably.

    This is especially a problem in your “Nootropics Expert Recommendation
    L-DOPA (Mucuna Pruriens) 250 – 500 mg per day”.

    What exactly are you recommending? 250 – 500 mg of mucuna or 250 – 500 mg equivalent of actual L-DOPA . If it is ground mucuna pruriens seed you must also specify the potency – i.e. the concentration of L-DOPA in the particular mucuna product.

      Jay, L-DOPA is extracted from Mucuna Pruriens. But you cannot buy a pure L-DOPA supplement. Most Mucuna Pruriens supplements are 15 – 20% L-DOPA. For ‘normal’ healthy people I just recommend 250 – 500 mg twice per day Mucuna Pruriens. That is assuming you are getting a standard Mucuna Pruriens extract supplement.

      But if you have Parkinson’s then I recommend a Mucuna Pruriens extract of 99% L-DOPA. That is not what I’m talking about in this review.

          Jay, that is why I welcome feedback and pointing out things that I get wrong. Fortunately, no harm done with this because used just once a day means you only get Mucuna Pruriens benefits for part of the day.

          The half-life of this extract is around 2 hours. So if someone was treating Parkinson’s Disease with Mucuna Pruriens extract and depending on the strength of the extract you’d want to use it 3-times per day to get all day benefits from this supplement.

          The largest study done comparing natural Mucuna Pruriens to levodopa/carbidopa also used much higher doses of the supplement than what I am suggesting (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5539737/). Because it was not an extract.

    Hello David
    I have been following your articles since last year and I feel that I have really got a treasure.

    If you allow some inquiries about Mawkana:

    1- Does it have any effect on women’s hormones and menstruation?
    Because I read it leads to raising the rate of testosterone
    Can women use this herb without fear of hormone problems
    And without increasing body hair or changing sound to roughness?

    – What about its effectiveness to treat attention deficit?

    – Can I take it with Ginkgo Biloba herb ?
    Once again, thank you, your articles are very useful and detailed.

      What is Mawkana? If you are trying to deal with ADD or ADHD then the supplement in the yellow box near the top of this article will help: https://nootropicsexpert.com/best-nootropics-for-adhd-add/. And notice that it uses L-Tyrosine instead of L-DOPA. There are a number of reasons why you should use L-Tyrosine instead of L-DOPA unless you are dealing with Parkinson’s Disease. If that is the case then I do recommend L-DOPA.

          Salem I hear this all the time. And it is wrong. If you are getting benefits from using a supplement that increases dopamine that means you were not making enough dopamine before you started using that supplement. Why after a couple of months would your system magically begin to make enough dopamine on its own? It did not do so before.

      Robert, theoretically the amino acid L-DOPA will compete for transporters with the amino acids in your food which use the same transporters. But it is my opinion that the amount of L-DOPA in the supplement you are using is much much higher compared to the amount in food.

      It has been my experience that I get the benefits from the supplements that I am using every day and long-term that I do not worry about the “empty stomach” and “take it with food” thing.

    Is one of the symptoms of low dopamine, body is out of balance?

      Chris, I let you Google “what are the symptoms of low dopamine”.

      But the difference between L-Tyrosine and L-DOPA is relevant. The dopamine pathway goes like this: Phenylalanine → Tyrosine → L-DOPA → Dopamine → Norepinephrine.

      L-DOPA will make more dopamine as soon as it gets to your brain. You need to get the dose exact or you’ve got problems. L-Tyrosine however is easier to dose, and safer to use long-term. L-Tyrosine is also required to make Thyroid Hormones. L-DOPA does not contribute to making Thyroid Hormones.

      The only time I recommend L-DOPA is if you are dealing with Parkinson’s Disease.

    I have periodic limb movement disorder where I kick a lot during sleep. This is disruptive and leads to waking every night and unrefreshing sleep. I also don’t feel a lot of pleasure and seem to be low on dopamine. I’ve read that some people take synthetic L-DOPA with good results. Do you think taking Mucuna Pruriens is worth trying? If so, what dosage and would I take this before bed?

        I took your recent advice (on a different page of the website) and got my hormone levels tested because I feel like crying every single day and constantly think sad thoughts.

        The test results came back normal, so now I’m trying to decide which nootropic to add to the Lamotrigine I take as a mood stabiliser.

        Do you have any recommendations based on the crying issue please? Sorry to bother you again, I’m just desperate.

          Chris, Lamotrigine is a sodium channel blocker which suppresses the release of the excitatory neurotransmitters glutamate and aspartate. One of its side effects are mood changes. And the only way to avoid those side effects is not use the drug. Which I am NOT recommending. I just want you to know what you may be dealing with.

          You can try increasing dopamine by using L-Tyrosine to see if that helps.

    I have been unable to walk for most of 2022. At one point I tried 2400mg of mucuna extract (360mg L Dopa) once a day in addition to multiple other drugs/supplements and had some noticeable improvement but it wasn’t lasting. Since stopping it I have been taking oral liposomal methylene blue (MB) (100mg a day) and my doctor wants me to try a dopamine treatment again. He suggested starting at a very low dose of Sinemet (5mg/50mg) once a day to test if I have a major dopamine deficiency. I know that Sinemet and Methylene Blue are majorly contraindicated due to both being MAOIs. How does the synthetic levodopa compare in efficacy to naturally occurring L Dopa? Would L Dopa be safer to combine with MB than the Sinemet with less synthetic dopamine than the mucuna has of natural dopamine? Thanks so much!

      Mark, Methylene Blue is a potent MAOI which is why it is contraindicated with anything that directly increases dopamine. That includes L-Tyrosine, natural L-DOPA extracted from Mucuna Pruriens as well as Sinemet. The only way I would suggest trying using both is under the direct supervision of your doctor. Because you must avoid a hypertensive crisis (i.e. heart attack).

      Synthetic levodopa/carbidopa is theoretically similar to natural L-DOPA. Carbidopa is added to levodopa to avoid the side effects caused by using levodopa on its own. Natural L-DOPA on the other hand does not cause the same side effects as synthetic levodopa.

      But both are contraindicated with Methylene Blue.

    I’m a bit confused about the terms used. Please help correct my understanding.

    Levodopa is the synthetic version of L Dopa, it requires Carbidopa to get thru the blood Brain barrier.

    L Dopa is Pure Natural levodopa extract from Mucuna. Doses it contain any other ingredients from the bean to help in getting it to the brain or does it require something to help in the synthesis to get to the brain.

    Mucuna extract is the Mucuna bean and all its natural ingredients including small percentage of L Dopa/levodopa which along with other ingredients help make it to cross the blood brain barrier. Because the amount of L Dopa in the extract is small, it requires large amounts of the extract other wise little L Dopa would get to the brain to be effective.

    Do I have all this right. I so what is the best way to use Mucuna to get away from using Carbidopa Levodopa (Synthetic) For Parkinsons

    Thanks for your insight
    Is my understanding correct?

      Richard, carbidopa is combined with levodopa to prevent it from being converted into dopamine in the bloodstream which is what causes the severe side effects of using levodopa on its own. That combo actually allows more levodopa to cross the blood-brain barrier instead of allowing it to get carried throughout your body.

      Natural L-DOPA extracted from Mucuna Pruriens does not cause the same side effects in your system as does synthetic levodopa. I have consultation clients successfully switching from the drug to natural L-DOPA. But you need to find an extract of 95 – 99% which are difficult to find. But they do exist.

      Ida, the danger is increasing norepinephrine too much. Which will increase once you boost dopamine by using Mucuna Pruriens. So theoretically and most likely clinically it is contraindicated. But I need to know the specific name of the drug to know if it could be a real problem.

          Derek, L-DOPA is a direct precursor to the production of dopamine which goes on to produce norepinephrine. It is moderately contraindicated with desvenlafaxine so you need to be careful. As soon as you start feeling something you should not be feeling then back off of the L-DOPA.
