結論
CBD may support better sleep in people whose rest is disrupted by anxiety, though results are mixed and the best dose and formulation are still being studied.
- 35 studies with 17,358 participants — the largest evidence base among anxiety-sleep supplements
- Roughly 54% of studies show positive effects, with others showing mixed results
- May work through 5-HT1A serotonin receptors to reduce anxiety and promote sleep
- Dosing varies widely across studies (25 mg to 300+ mg), making direct comparisons difficult
