Ashwagandha as a daily adaptogen, answered.

What is an adaptogen, and is ashwagandha one?
Adaptogens are plants that help the body resist and adapt to stress. Ashwagandha (specifically KSM-66®) is among the most clinically studied adaptogens available.
Can I take ashwagandha every day, long term?
It is studied for daily use across 8 to 12 week trials and commonly taken longer. Optibio is root-only and third-party tested. Check with your prescriber if you take medication or are pregnant or nursing.
Do I need to cycle ashwagandha?
There is no strong evidence you must cycle KSM-66®. Many take it continuously; others take breaks. Consistency is what drives results.
