Anxiety Relief
About this protocol
Where to start
Start with L-theanine for acute moments. 200 mg 30-60 minutes before a known stressor (presentation, social event, difficult call) reduces subjective anxiety without sedation. Non-habit-forming.
Add magnesium glycinate as daily baseline. Subclinical magnesium deficiency is overrepresented in chronically anxious adults; supplementation has modest but consistent effects on subjective anxiety. Effect builds over 2-4 weeks.
Add ashwagandha (KSM-66) if chronic stress is part of the picture. The trial evidence is strongest for general anxiety symptoms and HPA-axis modulation over 8 weeks. Not appropriate for pregnancy, thyroid conditions, or autoimmune flares.
Add passionflower as an evening option for "anxious wakefulness." Modest evidence for sleep-onset anxiety and GAD symptoms.
Saffron is emerging — small trials suggest comparable effects to SSRIs for mild-to-moderate anxiety, but the literature needs replication.
If your anxiety is severe, includes panic attacks, persistent intrusive thoughts, or significantly disrupts work/relationships, see a therapist or psychiatrist. CBT and SSRIs/SNRIs have far larger effect sizes than any supplement.
5 nutrients
Start here
Strongest evidence — the foundation of the stack.
L-Theanine
100-200 mg, as needed for acute anxious moments (or 200 mg twice daily for ongoing use)L-theanine increases alpha-wave brain activity associated with relaxed alertness. Trial evidence supports an acute reduction in stress and anxiety symptoms after a single dose, with effect onset within 30-60 minutes. Non-sedating — does not impair cognition or motor function. Excellent for acute situations (presentations, flying, social events) and as a daily baseline supplement for ongoing low-level anxiety.[1, 2, 3]
Magnesium Glycinate
200-400 mg elemental, daily (split AM/PM if higher dose)Magnesium modulates NMDA receptors (excitatory) and GABA-A receptors (inhibitory), shifting the balance toward calm. Systematic reviews suggest a small but consistent effect of supplementation on subjective anxiety, particularly in adults with low dietary intake. The glycinate form is gentle on the GI tract and pairs with the calming glycine carrier. Effect builds over 2-4 weeks of consistent use.[4, 5, 6]
Add if needed
Add these only if the foundation isn't enough.
Ashwagandha (KSM-66)
600 mg, with breakfastAshwagandha lowers HPA-axis activation. Multiple randomized trials in chronically stressed adults found reductions in serum cortisol, subjective anxiety, and PSS scores after 8 weeks. KSM-66 is the most-studied standardized extract. Not sedating — works on the chronic anxious baseline, not acute episodes.[7, 8, 9]
Passionflower (Passiflora incarnata)
400-500 mg standardized extract, eveningPassionflower has historical use for anxiety and small randomized trials supporting effects on generalized anxiety disorder and sleep-onset anxiety. The mechanism appears to involve GABAergic modulation. Modestly sedating — best taken in the evening. Use a standardized extract.[10, 11, 12]
Experimental
Emerging evidence — try last, only if curious.
Saffron (Affron or Crocus sativus)
28-30 mg standardized extract daily, with breakfastSaffron has emerging trial evidence for mood and anxiety symptoms — small studies suggest effects comparable to SSRIs for mild-to-moderate symptoms. The literature is dominated by Iranian trials and the sample sizes are small. Treat as the most speculative item — worth a 12-week structured trial with measurable endpoints.[13, 14, 15]
Warnings
Lifestyle improvements
Therapy beats supplements for chronic anxiety
CBT (cognitive behavioral therapy) has the strongest evidence base of any anxiety intervention — typically larger effect sizes than medications, and far larger than supplements. If you have ongoing anxiety, finding a CBT-trained therapist is the highest-leverage step.
Breath work for acute anxiety
Box breathing (4-4-4-4) or physiological sighs (two quick inhales, one long exhale) measurably lower anxiety in 30-60 seconds. Free, fast, and works in any setting.
Cardio 3-4× weekly
Moderate aerobic exercise reduces anxiety symptoms with effect sizes comparable to some pharmacological interventions. 20-30 minutes, zone 2 (you can hold a conversation).
Reduce caffeine
Caffeine is biochemically anxiogenic — it raises cortisol and amplifies adrenaline. Many chronically anxious adults are over-caffeinating without realizing the connection. Try cutting caffeine in half for 2 weeks as a self-experiment.
Limit alcohol
Alcohol provides short-term relief but rebound anxiety the next day is well-documented. The chronic anxiety/alcohol cycle is one of the most common patterns in adult mental health.
Sleep is upstream
A single night of poor sleep raises next-day anxiety reactivity. Address sleep first if it's compromised — see the Better Sleep protocol.
Reduce news and social media
Chronic exposure to threatening or polarizing content trains the nervous system to scan for threat — measurable in cortisol and HRV studies. Time-bound your news consumption.
Connect with people in person
Loneliness and chronic anxiety are strongly linked. One 30-minute in-person interaction with a trusted person daily is a baseline most anxious adults under-deliver on.
