Cowhage is a tropical legume also called Mucuna pruriens or velvet bean. Its seeds supply L-DOPA, the direct precursor to the neurotransmitter dopamine. Extracts are standardized to a set L-DOPA content.
People take it for mood balance, everyday stress, and sharper focus. Some use it to support vitality and sex drive, though the evidence is weaker there. Benefits are tied to the brain having more dopamine available.
Take it once daily. Morning or early afternoon works best, and having it with food often prevents nausea. Avoid late-day doses. Since the extract is stimulating, taking it too close to bedtime can disrupt sleep. Potency differs between products, so follow the label for the product you have.
Watch for interactions. Cowhage can interfere with MAOIs, antipsychotics, and drugs for Parkinson's disease. It may drop blood pressure or cause stomach upset. Skip it if you are pregnant, nursing, or have a history of psychosis.
