Learn about MAO inhibitors: how they work in depression, risks of food interactions, and supportive natural treatment options.
Add as Preferred SourceMonoamine oxidase inhibitors (MAO inhibitors, MAOIs) are a class of antidepressants that block the enzyme monoamine oxidase.
Monoamine oxidase breaks down neurotransmitters such as serotonin, norepinephrine, and dopaminein the brain. By inhibiting it, MAOIs increase neurotransmitter levels in the synaptic cleft, improving mood and reducing symptoms of depression.
MAOIs are mainly prescribed for severe or treatment-resistant depression, when other antidepressants fail. Side effects may include hypertensive crises, dizziness, headaches, or weight gain. Because MAOIs interact with certain foods (e.g., cheese, red wine – tyramine-rich foods) and medications, patients must follow a strict diet and remain under close medical supervision.
In addition to pharmacological therapy, natural approaches can provide supportive benefits. These include St. John’s wort for mild depression, regular exercise, a balanced diet, mindfulness practices, and supporting the gut-brain axis. While not a replacement for medication, these measures may help improve symptom management.
