Best Supplements for Anxiety: Evidence-Based Rankings 2026
Anxiety supplements with genuine clinical evidence include ashwagandha (strongest for chronic anxiety), L-theanine (best for acute situational anxiety), magnesium glycinate (deficiency-driven anxiety), and lavender oil (oral Silexan — a surprising RCT-backed option).
Conclusion
For chronic anxiety: ashwagandha KSM-66 300 mg twice daily, 8 weeks minimum. For immediate effect: L-theanine 200 mg. For underlying deficiency: magnesium glycinate 300–400 mg nightly. Combine as needed — they are safe together.
