If you've tried everything and still don't feel right, here's why.

Conventional psychiatry is built around symptoms and medications. It isn't designed to ask what's driving those symptoms at a biological level. If nobody has ever tested your gut microbiome, your cortisol rhythm, your nutrient status, your food sensitivities, or your genetic variants — your treatment has been based on incomplete information. That's not a personal failing. That's a gap in the system.

A different kind of investigation.

FxMed Mental Health is a virtual functional medicine group practice built for people with complex, treatment-resistant mental health conditions. We run the most comprehensive testing available — six specialized panels that examine every biological system connected to mood, cognition, and mental health. Then we build a personalized, phased protocol to address what we actually find.
