When to Choose Ashwagandha Root and Leaf Extract (e.g. Sensoril)
Choose ashwagandha root and leaf extract when you want a lower-dose capsule and accept less traditional precedent. Leaf is not part of traditional Ayurvedic preparations; regulators in some countries restrict leaf use.
Ashwagandha Root and Leaf Extract (e.g. Sensoril)
Sensoril and Shoden include leaf, which raises both the withanolide percentage and the withaferin A content. Separate, smaller evidence base.
What to look for: The dose used in that extract's own trials, such as 240 mg for Shoden. Do not compare withanolide percentages across brands.

Choose ashwagandha root powder when you want the traditional preparation and accept unstandardized content. Most clinical trials used standardized extracts, not raw powder, so trial doses do not translate.
Ashwagandha Root Powder
Cheap and unstandardized. Not what the trials used.
What to look for: Skip it unless you prefer traditional preparations; the withanolide dose per gram is unknown.
