A good fit for Comparing the exact composition of an ashwagandha combination with simpler single-ingredient root extracts.
- The manufacturer separates the actual 250mg root extract from the larger 3000mg equivalent headline.
- Its table declares L-tryptophan, vitamin B6 and black pepper quantities, so the additional ingredients are visible rather than hidden in a blend total.
A combination has different evidence and interaction questions from standalone ashwagandha. The stress, sleep and hormone marketing is not proof of those effects for this exact capsule.

Ashwagandha KSM-66 — Some extract-specific short-term stress and sleep evidence exists; broad hormone and long-term claims remain uncertain. Benefits, women’s context & cautions

The details that matter.
- Photographed pack
- 60 vegan capsules in a resealable pouch
- Manufacturer serving
- 1 capsule
- Ashwagandha extract
- 250mg KSM-66 root extract, listed as 12:1 and standardised to 5% withanolides
- Ashwagandha root equivalent
- 3000mg; not the extract weight
- Other amounts per capsule
- L-tryptophan 200mg; vitamin B6 1.7mg; black pepper 10:1 extract 20mg
- Black pepper equivalent
- 200mg powder equivalent; not 200mg extract
- Avoid during pregnancy or breastfeeding. Thyroid or autoimmune disorders, liver concerns and regular medicines require professional review.
- Do not infer safety or effectiveness of the entire mixture from studies of KSM-66 alone. L-tryptophan and black pepper are additional ingredients to review.
- NCCIH notes rare liver-injury reports and uncertainty about long-term use. A manufacturer cycling suggestion does not resolve those concerns.
Cycling & duration.
Ingredient timeframes describe the cited preparation; they do not establish a cycle for every finished formula.
Calm+ KSM-66 Ashwagandha Complex - 60 Capsules
- On/off pattern
- No clinically validated on/off schedule for this complete Calm+ formula.
- Duration & evidence
- NCCIH describes ashwagandha safety evidence for up to about 3 months, with longer-term safety uncertain. This is not a recommended course or a validated repeat-cycle for the mixture.
- When to review
- Review the goal, exact formulation, response and medicines before continued use, and sooner if unwanted effects develop.
- The manufacturer FAQ suggests breaks, but that suggestion is not evidence that a particular on/off calendar improves effectiveness or prevents harm.
- L-tryptophan, vitamin B6 and black pepper make this different from an ashwagandha-only trial; the pouch's two-month supply is not a validated treatment duration.
