ABOUT
Jennifer Theriault, PMHNP-BC
Psychiatric Nurse Practitioner — Functional & Metabolic Psychiatry
Jennifer Theriault, PMHNP-BC, is a nurse practitioner specializing in functional and metabolic psychiatry, dedicated to uncovering the root causes of mental health challenges and guiding patients toward long-term emotional and cognitive wellness.
With over 27 years in healthcare, Jennifer's approach integrates hormonal, nutritional, and metabolic interventions alongside circadian psychiatry, functional testing, and personalized therapeutics. Her practice blends evidence-based strategies with cutting-edge science, ensuring every treatment plan is tailored to a patient's unique biochemistry, metabolism, and psychological health.
HER APPROACH
Jennifer specializes in conditions such as anxiety, depression, bipolar disorder, ADHD, PTSD, and OCD, focusing on metabolic balance, hormone optimization, and cognitive resilience rather than symptom suppression alone.
Her method begins with a foundations first approach, establishing the core pillars of how you move, eat, and sleep. Once these are stabilized, the focus shifts to restoring circadian alignment, optimizing cellular charge through grounding, sunlight, and red light exposure, supporting hydration, and refining sleep architecture. Together, these create the conditions for both biochemical stability and emotional resilience.
Genetic & Biochemical Precision
Genetic testing informs psychopharmacologic decisions and individualized diet and supplement strategies, integrating long-term preventive and restorative care into every plan.
AREAS OF FOCUS
Metabolic & Hormonal Psychiatry
Diet, movement, and when appropriate, GLP-1/GIP therapy support psychiatric and metabolic recalibration. Hormonal optimization for both women and men, alongside oxytocin support for connection and emotional regulation.
Cellular & Nervous System Resilience
Treatment stacks supporting ATP production and neurotransmitter balance, including NAD+, B12, and methylene blue protocols for neuroprotection and cognitive clarity, plus low-dose naltrexone and peptide therapies for inflammation and mood stability.
Beyond Traditional Psychiatry
Jennifer believes mental health cannot be addressed in isolation. Her practice is not a conventional psychiatry clinic, but a metabolic psychiatry model built on sleep and circadian alignment, nutrient-dense hydration and diet, movement and stress mitigation, and deep relationships and life purpose.
Rather than one-size-fits-all medication management, she weaves in CBT techniques, motivational interviewing, and somatic and supportive therapy as part of a comprehensive care model, never standalone talk therapy.
Currently advancing her training in Integrative and Functional Psychiatry through a fellowship with Psychiatry Redefined, and studying to sit for The Menopause Society board certification
