Functional psychiatry is an approach that seeks to understand the root causes of mental health symptoms by examining how different biological systems and environmental factors influence brain function and emotional regulation.

It focuses on identifying underlying physiological contributors to psychiatric symptoms, such as:

• Nutritional deficiencies (e.g., omega-3s, B-vitamins, iron, vitamin D)

• Gut–brain axis disturbances (microbiome imbalance, malabsorption)

• Inflammatory and immune processes

• Mitochondrial or metabolic dysfunction

• Sleep and circadian rhythm disruption

• Hormonal or adrenal stress responses (HPA axis)

• Environmental stressors and toxin exposure

• Genetics and epigenetic factors

The goal is to understand why symptoms are occurring—not just to treat the symptoms themselves.
