Mucuna and L-DOPA: Parkinson's Medicines and MAOIs

What is mucuna pruriens, and why does L-DOPA matter?

Mucuna pruriens is a climbing tropical bean, and its seeds contain L-DOPA, the compound Parkinson's medicines are built around.

The HoneyBoost panel row reads "Mucuna (Mucuna pruriens) Seed Extract standardized to 98% L-DOPA (9.8 mg)", with 10 mg beside it (HoneyBoost label). A Dutch assessment found mucuna labels listing levodopa at 15% to 40% of the extract (RIVM 2024, mucuna risk assessment). The HoneyBoost row says 98%; no lab report is on file.

How much L-DOPA is in one HoneyBoost gummy?

One gummy holds 10 mg of mucuna extract, and at 98% that is 9.8 mg of L-DOPA (10 x 0.98).

The one study we read gave 5 g (5,000 mg) of seed powder a day for 3 months to 60 stressed, infertile men, with no placebo group (Shukla 2010, mucuna in men). The gummy's 10 mg is 0.2% of that (10/5,000), and powder differs from extract. No trial tested HoneyBoost.

Is mucuna safe with Parkinson's medicines and MAO inhibitors?

Nobody can promise that, so ask a pharmacist first: the Dutch assessment could set no safe dose.

It called the MAO-inhibitor and Parkinson's medicine interactions theoretical and advised avoiding mucuna in pregnancy, breastfeeding and with liver or kidney problems (RIVM 2024, mucuna risk assessment). The label says not to take the gummy if you take other medications. More in our medicine interactions guide.

Keep taking prescribed medicine

Who should talk to a clinician first?

Anyone on regular medicine, with heart, liver or kidney disease, or pregnant, breastfeeding or under 18 should talk to a clinician first.

Tongkat ali, another row, is a possible rare cause of liver injury; dark urine, yellow skin or eyes means get care (LiverTox, tongkat ali). See who should not take HoneyBoost.

Answer all 8Your result shows here. It is a checklist, not medical advice.

Are you under 18, pregnant, lactating, or buying for someone who is? The label says not intended for use under 18 and not to be taken if pregnant or lactating.

Do you take any prescription medicine, especially nitrates, an ED drug, blood pressure, Parkinson's, MAO-inhibitor, diabetes or blood-thinning medicine? The label says not to take it if taking other medications, and the Dutch mucuna assessment flags MAO-inhibitor and Parkinson's medicines. Ask your doctor or pharmacist.

Do you have a heart condition, low or high blood pressure, or chest pain with effort? Arginine can lower blood pressure, and erectile problems can be an early sign of heart disease. Ask your clinician first.

Do you have liver disease, or have you had liver trouble before? LiverTox rates tongkat ali a possible rare cause of liver injury. Talk to your clinician before taking it.

Are you hoping this treats erection problems or low testosterone? Neither is treated by a supplement: erectile problems can signal heart or blood-vessel disease, and low testosterone needs blood tests. A clinician can help.

Do you have a medical condition under treatment, such as diabetes or a thyroid problem? The label says not to take it with a medical condition and to consult a physician. Do not change a prescribed medicine because of a supplement.

Do you have chest pain, fainting, trouble breathing, or an erection that has lasted 4 hours or more right now? Chest pain, fainting or trouble breathing: call 911 now. An erection of 4 hours or more is an emergency: go to the emergency room.

Are you allergic to peanuts, tree nuts, wheat, soy or milk? The label says it is packaged in the same facility as peanuts, tree nuts, wheat, soy and milk products. Ask your clinician.

FAQ

HoneyBoost questions people ask

Does HoneyBoost contain L-DOPA?

Yes. The panel prints a mucuna seed extract standardized to 98% L-DOPA, 10 mg per gummy, or 9.8 mg of L-DOPA (10 x 0.98). L-DOPA is also used in Parkinson's medicines.

Can I take mucuna with an MAO inhibitor?

Ask a pharmacist first. The Dutch assessment called the interaction theoretical but worth a warning, with no safe dose set.

Is the 98% L-DOPA figure verified?

We cannot say. The panel prints it, but no lab report is on file and the label names no measurer.
