Mucuna Pruriens
Morning
Mucuna pruriens, commonly called velvet bean, is a tropical legume native to Africa and Asia that has been used in Ayurvedic medicine for centuries. Its seeds are uniquely rich in L-DOPA, the direct biosynthetic precursor to dopamine, making it one of the most potent natural sources of this neurotransmitter building block. The supplement has drawn research interest for both neurological and reproductive health applications.

Safety & Cautions
Side Effects
- Nausea and digestive discomfort
- Dopamine crash after effects wear off
- Insomnia at higher doses
- Headache
Mucuna pruriens should not be combined with L-DOPA medications (such as carbidopa-levodopa) due to the risk of dangerously elevated dopamine levels. It is contraindicated for individuals with bipolar disorder, mania, or schizophrenia, and should be used cautiously by those on blood sugar–lowering medications due to potential hypoglycemic effects.
