Evidence-Based Protocol
Supplement stack ranked by research quality
Primary Stack (Tier 1)
Supports brain function; anti-inflammatory effects may help with PTSD-related changes in brain
Deficiency associated with PTSD; supports brain function and mood regulation
Supporting Stack (Tier 2)
Supports GABA function and nervous system; may help with anxiety and sleep
Modulates glutamate; antioxidant; may help with intrusive symptoms
Gut-brain axis support; may help with stress response and mood
Adaptogen that may reduce cortisol and help with stress/anxiety
Promotes calm alertness; may reduce anxiety without sedation
Involved in stress response; deficiency may worsen PTSD symptoms
Helps with sleep disturbances common in PTSD; may reduce nightmares
How It Works
PTSD develops after experiencing or witnessing a traumatic event - combat, assault, accidents, disasters, or other life-threatening situations. It involves re-experiencing symptoms (flashbacks, nightmares, intrusive memories), avoidance of trauma reminders, negative changes in thoughts and mood, and heightened arousal (hypervigilance, startle response, sleep problems, irritability). PTSD affects the brain's fear circuitry, stress hormone systems, and inflammatory markers.
CRITICAL: PTSD is a serious psychiatric condition that requires professional treatment. Evidence-based therapies include trauma-focused cognitive behavioral therapy (CPT, PE), EMDR, and medication (SSRIs: sertraline, paroxetine are FDA-approved). Effective treatment significantly reduces symptoms and improves quality of life. These supplements may provide adjunctive support but are NOT replacements for therapy and/or medication. If you're experiencing PTSD symptoms, please seek help from a mental health professional. Crisis resources: National Suicide Prevention Lifeline 988, Veterans Crisis Line 1-800-273-8255 (Press 1).
* Omega-3 Fatty Acids support brain health and have anti-inflammatory effects. Some studies show benefit for PTSD symptoms, particularly at higher EPA doses.
* Vitamin D deficiency is very common in PTSD patients and associated with worse symptoms. Optimizing levels may support treatment response.
* Magnesium supports GABA function (the calming neurotransmitter) and may help with anxiety and sleep. Magnesium threonate crosses the blood-brain barrier.
* NAC modulates glutamate and has antioxidant effects. It's being studied for various trauma-related conditions.
* Probiotics support the gut-brain axis, which is increasingly recognized as important in stress and mood disorders.
* Ashwagandha is an adaptogen that may help reduce cortisol and stress response.
* L-Theanine promotes calm alertness without sedation.
* Melatonin can help with the sleep disturbances and nightmares common in PTSD.
Expected timeline: Supplements may provide gradual support over weeks to months. Evidence-based treatments (therapy, medication) typically show improvement within 8-12 weeks. PTSD often requires ongoing management.
