Frequently Asked Questions
How much ashwagandha should I take for anxiety?
For stress and anxiety, take 300–600 mg of KSM-66 ashwagandha extract daily, split into two doses (morning and evening). Studies show significant cortisol reduction within 4–8 weeks.
What is the difference between KSM-66 and Sensoril?
KSM-66 is a root-only extract (5%+ withanolides) and is the most studied form. Sensoril uses root + leaf (10%+ withanolides) and is effective at lower doses. Both work — KSM-66 has more clinical trials behind it.
Can I take ashwagandha every day?
Yes, for up to 3 months continuously. Most experts recommend cycling: 2–3 months on, 2–4 weeks off. Long-term daily use beyond 3 months has less safety data.
