Ketamine targets the glutamate system imbalance at the core of OCD while metabolic psychiatry addresses the mitochondrial dysfunction and inflammation that keep your brain stuck in obsessive loops. Emerging Harvard research shows ketogenic metabolic therapy can reduce OCD symptoms by over 90%.
OCD involves dysfunction in the cortico-striato-thalamo-cortical (CSTC) circuit — a brain network that gets “locked” into repetitive patterns. Research increasingly points to glutamate system dysregulation as a primary driver of OCD. Elevated glutamate in the orbitofrontal cortex and caudate nucleus creates excessive neural excitability — the biological basis of the obsessive loop. Standard SSRIs address serotonin but leave the glutamate imbalance untouched.
Up to 40-60% of OCD patients don’t achieve adequate relief from SSRIs. Exposure and Response Prevention (ERP) is the gold standard psychological treatment, but it requires the brain to have sufficient flexibility (neuroplasticity) to form new patterns — something many treatment-resistant patients lack. When the underlying neurobiology isn’t addressed, willpower and exposure alone may not be enough.
Harvard researchers Dr. Christopher Palmer and Aaron MacDonald published a groundbreaking case series (2024) of three individuals with OCD who achieved medication-free remission and a 90.5% reduction in symptoms after adopting a ketogenic diet. This builds on the Brain Energy theory: when brain cells — particularly in the OFC and basal ganglia — lack adequate energy from mitochondrial dysfunction, the CSTC circuit malfunctions. Providing ketones as alternative brain fuel may restore normal circuit function.
Most conventional depression treatment focuses narrowly on symptom suppression. While SSRIs can be helpful for some patients, they represent just one small piece of a much larger biological puzzle.

A: OCD is increasingly understood as a glutamate system disorder. Ketamine directly modulates glutamate signaling, reducing the excessive neural excitability in the cortico-striato-thalamo-cortical (CSTC) circuit that drives obsessive-compulsive patterns. It also promotes rapid neuroplasticity, making the brain more responsive to behavioral therapies like ERP.
A: Harvard researchers have demonstrated that mitochondrial dysfunction — impaired cellular energy production — may underlie OCD by disrupting the brain circuits that normally suppress repetitive thoughts and behaviors. A 2024 case series by MacDonald & Palmer showed three patients with treatment-resistant OCD achieved 90.5% symptom reduction and medication-free remission using a ketogenic diet, which provides ketones as alternative brain fuel.
A: Emerging evidence from Harvard suggests yes. The MacDonald & Palmer case series showed dramatic results in three patients with treatment-resistant OCD. This is consistent with the Brain Energy theory and parallels the well-established use of ketogenic diets for epilepsy — another condition involving excessive neural excitability. Clinical trials are ongoing. At Seaside Ketamine, we assess metabolic factors and may recommend dietary interventions as part of a comprehensive plan.
A: Several supplements have evidence supporting their use in OCD, including N-Acetylcysteine (NAC) which modulates glutamate, inositol, magnesium, and certain B vitamins. However, we don’t recommend generic supplements. Through Seaside Longevity, we use genetic and metabolomic testing to identify your specific biochemical imbalances and create truly personalized protocols.
A: Treatment plans are individualized. Many patients begin with a series of ketamine sessions combined with metabolic optimization. OCD typically requires integration with behavioral therapy (ERP) to achieve lasting results.
A: Absolutely. We encourage collaboration with your existing OCD therapist. The neuroplastic window created by ketamine may enhance the effectiveness of ERP and other behavioral interventions.
A: Yes. Ketamine’s effect on the glutamate system is well-established in research literature. Metabolic approaches to OCD are newer but supported by published case series from Harvard researchers and aligned with the broader metabolic psychiatry evidence base. Multiple clinical trials of ketogenic therapy for psychiatric conditions are now underway at major research institutions worldwide.
A: Most patients begin treatment while continuing their current medications. When appropriate and desired, we can support gradual medication adjustments as part of the treatment plan. Pharmacogenomic testing helps optimize any medications you continue taking.
If SSRIs and ERP haven’t given you the relief you deserve, emerging metabolic and ketamine-based approaches offer real hope.
