Evidence-Based Protocol

Supplement stack ranked by research quality

Moderate Evidence

Primary Stack (Tier 1)

2-3g EPA+DHA daily (higher EPA ratio)

Supports brain function; anti-inflammatory effects may help with PTSD-related changes in brain

12 studies | 600 participants
2000-4000 IU daily (target 40-60 ng/mL)

Deficiency associated with PTSD; supports brain function and mood regulation

8 studies | 500 participants

Supporting Stack (Tier 2)

300-400mg daily (glycinate or threonate)

Supports GABA function and nervous system; may help with anxiety and sleep

8 studies | 400 participants
1200-2400mg daily in divided doses

Modulates glutamate; antioxidant; may help with intrusive symptoms

5 studies | 200 participants
20-50 billion CFU daily (multi-strain)

Gut-brain axis support; may help with stress response and mood

6 studies | 300 participants
300-600mg standardized extract daily

Adaptogen that may reduce cortisol and help with stress/anxiety

6 studies | 300 participants
200-400mg daily

Promotes calm alertness; may reduce anxiety without sedation

5 studies | 200 participants
15-30mg daily

Involved in stress response; deficiency may worsen PTSD symptoms

4 studies | 150 participants
1-5mg 30-60 minutes before bed

Helps with sleep disturbances common in PTSD; may reduce nightmares

6 studies | 250 participants

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.
