About Ashwagandha Withanolides
The steroidal lactones responsible for much of ashwagandha's activity, listed on some labels as a standardized marker rather than total extract weight. Evidence tracks the ashwagandha entry (stress/cortisol, sleep). Listed standalone so withanolide-marker rows resolve without misapplying the whole-extract dose range.

How much Ashwagandha Withanolides to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
5–50
mg
Withanolides are the standardized active marker of ashwagandha; clinical extracts deliver roughly 5-50 mg of withanolides (e.g. KSM-66 ~5%, Sensoril ~10%). Scored separately here because withanolide mg is ~10-20x smaller than whole-extract mg.
Clinical evidence
Moderate clinical evidence. Standardized active fraction of ashwagandha; see ashwagandha for trials
