Product Description
KSM-66 is a patented full-spectrum ashwagandha extract by Ixoreal Biomed, standardized to at least 5% withanolides. It is the most commonly used ashwagandha extract in clinical trials. Jarrow Formulas uses KSM-66 in their ashwagandha capsule.
What We Like
- KSM-66 extract: The most researched and standardized ashwagandha extract available
- Price: One of the cheapest sources of KSM-66 — the patented extract often commands a significant premium elsewhere
- 300 mg: Matches the per-dose amount used in studies (often 2x daily = 600 mg total)
- Vegan: Plant-based capsules
What We’re Missing
- No third-party certification
- Dosage: Studies recommend 600 mg daily for maximum stress reduction — one capsule covers only half that
- No direct quality verification of the finished product
Usage Recommendation
1–2 capsules daily, preferably in the evening. KSM-66 can cause drowsiness — evening dosing makes good use of that effect.
