Cycling & duration.
Ingredient timeframes describe the cited preparation; they do not establish a cycle for every finished formula.
Ashwagandha root preparation
- On/off pattern
- No validated on/off schedule is established for this ashwagandha preparation.
- Duration & evidence
- NCCIH describes short-term use up to 3 months, with long-term safety uncertain. That does not establish a recommended three-month course or a safe repeat cycle.
- When to review
- Review the exact root preparation, withanolide amount, response and medicines before continuing.
- KSM-66 research does not automatically set a duration for a different root extract or an extract-plus-powder combination.
- Pregnancy, breastfeeding, thyroid or autoimmune disorders and liver-injury concerns require particular attention; an off-week does not remove them.
