Does Ashwagandha really help with anxiety and stress?

Yes, Ashwagandha is clinically shown to reduce cortisol levels (the stress hormone) and alleviate symptoms of anxiety. Studies suggest taking 300-600 mg daily for 6-8 weeks can significantly improve stress resilience. However, it's not a substitute for medical treatment in severe cases.

What are the side effects of Ashwagandha?

Most people tolerate Ashwagandha well, but possible side effects include mild drowsiness, digestive upset, or headaches. Rare cases may experience thyroid hormone fluctuations. Avoid if pregnant, breastfeeding, or with autoimmune conditions unless approved by your doctor.

Can I take Ashwagandha at night for better sleep?

Yes, Ashwagandha's relaxing properties may improve sleep quality when taken 30-60 minutes before bed. The typical dose is 300-500 mg of root extract. However, some individuals report increased energy, so morning intake might be better for them.

How long does it take for Ashwagandha to work?

Most studies show noticeable effects within 2-4 weeks of consistent use, with peak benefits around 8-12 weeks. Stress relief may appear sooner (1-2 weeks), while cognitive or hormonal changes take longer. Consistency is key as effects are cumulative.
