Anxiety Relief

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 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]}

Ashwagandha 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 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]}

Saffron 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]}
