Frequently Asked Questions
Does ashwagandha really help with sleep?▼
Yes. A high-quality RCT (n=138, 8 weeks) showed significant improvements in sleep quality (PSQI), sleep onset latency, and sleep efficiency. It's particularly effective for those with stress-related insomnia.
How long does ashwagandha take to work for sleep?▼
Studies show significant improvements after 4-8 weeks of consistent use. Some individuals report benefits within the first week.
Is ashwagandha safe to take long-term?▼
Ashwagandha appears safe for up to 8 weeks. Long-term safety data is limited. Avoid during pregnancy and autoimmune conditions. Consult a healthcare provider for chronic use.
Related Claims
Magnesium supplementation improves sleep quality, especially in deficient or elderly populations
Magnesium supplementation (500mg) for 8 weeks significantly improves sleep efficiency, total sleep time, and PSQI scores in elderly adults with primary insomnia. Effects are most pronounced in individuals with magnesium deficiency.
L-theanine improves subjective sleep quality and reduces anxiety without causing drowsiness
L-theanine (200mg daily) improves subjective sleep quality and reduces anxiety in adults with high anxiety levels. Unlike many sleep aids, it does not cause daytime drowsiness and promotes relaxation via alpha-wave enhancement.
Melatonin reduces sleep onset latency by approximately 7 minutes in adults with primary sleep disorders
A comprehensive meta-analysis of 19 RCTs (1,683 participants) found melatonin reduces sleep latency by ~7 minutes and increases total sleep time by ~8 minutes. Effects are more pronounced in older adults and those with circadian rhythm disruptions.
