HelloPharmacist Scorecard of Mucuna by Moon Juice

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Moon Juice Mucuna is a single-ingredient powder: Mucuna pruriens seed extract, commonly called cowhage. This plant contains levodopa, an amino acid precursor that your body converts to dopamine, a brain chemical involved in mood, movement, and motivation.

The extract is the active ingredient here — there are no other active ingredients and no inactive fillers listed.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Cowhage's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: mood and dopamine support.
  • We looked for evidence on: Anxiety, Parkinson disease, Sexual desire, depression, motivation, stress resilience.
  • The closest evidence on file: Cowhage is rated "Insufficient Reliable Evidence To Rate" for Anxiety (Natural Medicines).
  • Also on file: Cowhage is rated "Insufficient Reliable Evidence To Rate" for Parkinson disease, Sexual desire.

The evidence we hold does not establish that cowhage is effective for anxiety, erythema (skin redness), hyperprolactinemia (elevated prolactin hormone), myalgia (muscle pain), Parkinson disease, or rheumatoid arthritis. All six conditions in our data are rated insufficient reliable evidence to rate, meaning the research to support its use is not yet solid enough to draw a conclusion.

The evidence, ingredient by ingredient Cowhage

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Cowhage is generally well tolerated when taken by mouth, though some people report diarrhea, flatulence, gas, dry mouth, nausea, stomach distention, vomiting, headaches, or insomnia — a small number of trial participants experienced insomnia. The safety data advises against use during pregnancy because there isn't enough safety information and its dopamine effects are a concern.

Similarly, the safety data advises against use while breastfeeding because levodopa can lower prolactin and reduce milk supply. Because this product contains levodopa, an active drug-like compound, it should be used carefully and with professional guidance.

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Cowhage.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: diabetes medications; Parkinson's medications.
  • For scale: 193 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take monoamine oxidase inhibitors (MAOIs) such as phenelzine or tranylcypromine, methyldopa, or levodopa, do not use this product — these are Major-level interactions. You should also check with your doctor or pharmacist if you take antidiabetes drugs, antipsychotics, tricyclic antidepressants, guanethidine, or if you're planning to have anesthesia involving cyclopropane or halogenated hydrocarbons.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

Moon Juice Mucuna is a straight levodopa supplement, which makes it powerful but also risky if you take any blood pressure medications, antidepressants (especially older ones), Parkinson's drugs, diabetes medications, antipsychotics, or are planning anesthesia. Before you start, talk it over with your doctor or pharmacist to make sure it's safe alongside anything else you take.

Macuna pruriens seed extract8 drug types · 193 drugs

Levodopa

Concomitant use can increase the risk of levodopa-related adverse effects.
Cowhage contains levodopa. Some cowhage products have been standardized to contain 75-400 mg of levodopa per dose.

Likelihood Likely Evidence D
Methyldopa (Aldomet)

Theoretically, concomitant use of cowhage and methyldopa might increase the risk of hypotension.
Cowhage contains levodopa. Use of levodopa with methyldopa might cause additive hypotension. In addition, methyldopa may inhibit peripheral decarboxylation of levodopa and increase levodopa levels in the central nervous system; avoid using.

Likelihood Probable Evidence D
Monoamine Oxidase Inhibitors (Maois)

Theoretically, concomitant use of cowhage and non-selective MAOIs might increase the risk of hypertensive crisis.
Cowhage contains levodopa. Use of levodopa with non-selective MAOIs might cause hypertensive crisis. However, this interaction has not been reported with MAO-B selective inhibitors such as selegiline.

Likelihood Probable Evidence D
Anesthesia

Theoretically, concomitant use of cowhage and anesthesia might increase the risk of arrhythmias.
Cowhage contains levodopa. Use of levodopa with cyclopropane or halogenated hydrocarbon anesthesia has led to arrhythmias. Other anesthetics have not been implicated. Use other anesthetics in patients taking cowhage or tell patients to stop taking cowhage at least 2 weeks before surgery.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of cowhage and antidiabetes drugs might increase the risk of hypoglycemia.
Animal research shows that cowhage might have hypoglycemic effects.

Likelihood Possible Evidence D
Antipsychotic Drugs

Theoretically, use of cowhage might decrease the clinical effects of antipsychotic drugs.
Cowhage contains levodopa. Use of levodopa might counteract the antidopaminergic effects of antipsychotic medications.

Likelihood Possible Evidence D
Guanethidine (Ismelin)

Theoretically, concomitant use of cowhage and guanethidine might increase the risk of hypotension.
Cowhage contains levodopa. Use of levodopa with guanethidine might cause additive hypotension; avoid using.

Likelihood Probable Evidence D
Tricyclic Antidepressants (Tcas)

Theoretically, use of TCAs might reduce the levels and clinical effects of cowhage.
Cowhage contains levodopa. Use of TCAs might reduce the absorption of levodopa. Some case reports describe patients that developed hypertension and dyskinesia when taking both levodopa and TCAs.

Mucuna by Moon Juice: Common Questions

Does Mucuna by Moon Juice interact with any medications?
Yes. Based on its ingredients, Mucuna has a known interaction with 193 medications, including 17 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Mucuna contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this while I'm pregnant?
No. The safety data advises against using cowhage during pregnancy because there isn't enough safety information and its dopamine effects raise concerns. Talk with your doctor or pharmacist about what's safe for you.
Can I take this while breastfeeding?
No. Levodopa, the active compound in cowhage, can lower prolactin levels and reduce milk supply. The safety data advises against use while breastfeeding.
What are the side effects?
Most people tolerate it well, but some experience diarrhea, gas, nausea, vomiting, dry mouth, stomach distention, headaches, or insomnia. A small number of trial participants reported insomnia.
Does this actually work for what it claims?
The evidence we hold does not establish that cowhage is effective for anxiety, skin redness, high prolactin, muscle pain, Parkinson disease, or rheumatoid arthritis. The research so far is insufficient to draw a conclusion.
Is this the same as L-dopa I might take for Parkinson's?
Both contain levodopa, but taking a cowhage supplement alongside Parkinson's medication could amplify unwanted levodopa side effects. Do not combine them without your doctor's approval.
