Jennifer Theriault, PMHNP-BC

Psychiatric Nurse Practitioner | Functional & Metabolic Psychiatry | Root-Cause Mental Health

Jennifer Theriault, PMHNP-BC, is a psychiatric 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 28 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 each patient receives a treatment plan tailored to their unique biochemistry, metabolism, and psychological health.

Innovative & Holistic Treatment Approach

Jennifer specializes in addressing conditions such as depression, anxiety, ADHD, PTSD, bipolar disorder, addiction, and neuroinflammatory disorders, focusing on metabolic balance, hormone optimization, and cognitive resilience rather than symptom suppression.

Her comprehensive approach begins by restoring universal lifestyle foundations—circadian alignment, cellular charge (grounding, sunlight, red light), hydration (including EZ water principles), and sleep architecture. These pillars form the fertile ground for biochemical and emotional resilience.

✅ Neuroendocrine and Metabolic Modulation

• GLP-1/GIP therapies (Tirzepatide, Semaglutide) for psychiatric and metabolic recalibration (compounded, out-of-pocket only)

• Oxytocin support for connection, emotional regulation, and parasympathetic tone

• Hormonal optimization for females and males: estradiol, progesterone, testosterone

✅ Mitochondrial & Cellular Vitality

• Niacinamide to support ATP production and neurotransmitter balance

• NAD+ and B12 for detoxification, methylation, and mitochondrial resilience

• Methylene Blue protocols for neuroprotection, cognitive clarity, and oxidative stress management

✅ Targeted Immune & Mood Regulation

• Low-Dose Naltrexone (LDN) to reduce neuroinflammation and stabilize mood

• Peptide therapies for brain-body restoration and metabolic signaling

✅ Thyroid & Biochemical Precision

• Advanced functional testing for thyroid health and hormonal synergy

✅ Lifestyle & Nervous System Coherence

• Sleep science, sensory regulation, and emotional clarity

• Movement, connection, and ancestral living principles

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 integrating foundational health strategies: 🌞 Sleep & circadian rhythm alignment 💧 Hydration & nutrient-dense dietary strategies 🏃‍♂️ Movement & stress mitigation ❤️ Deep relationships & life purpose development

Her philosophy rejects one-size-fits-all medication management, instead weaving in CBT techniques, motivational interviewing, and supportive therapy into a comprehensive care model—never standalone talk therapy.

Currently advancing her expertise in Integrative and Functional Psychiatry through her fellowship with Psychiatry Redefined, Jennifer remains passionate about revolutionizing mental health care. She ensures her patients receive personalized, transformative treatment, helping them build sustainable mental clarity, metabolic balance, and emotional resilience.
