Ashwagandha Leaf & Root Extract (Sensoril)
Also known as: Sensoril, Withania somnifera leaf and root extract, Sensoril ashwagandha, aqueous ashwagandha extract
A branded water-extracted ashwagandha made from both leaf and root and standardized to a minimum of 10% withanolide glycosides, which lets it work at a smaller dose than root-only extracts. It has been studied in healthy adults for cognitive and psychomotor performance and in recreationally active men for strength during a resistance-training program. Formulators reach for it when capsule space is tight or when a lower-milligram adaptogen is needed alongside other actives.
Research summary
Withanolide glycosides are thought to blunt stress-related cortisol output and support GABAergic tone, similar to root-only extracts but at a higher glycoside concentration.
Dosage
Daily amounts, of extract.
| Lowest studied | Typical range | Highest studied | Upper limit |
|---|---|---|---|
| — | 125–250 mg | 500 mg | — |
Marketed at 125 to 250 mg per day; published trials used 500 mg per day, either as a single dose or 250 mg twice daily, for 12 weeks or as acute dosing. Can be taken with or without food. Effects on stress markers accumulate over several weeks.
Standardization: ≥10% withanolide glycosides, leaf and root, aqueous extract
Source material: leaf and root aqueous extract

Bitter; low dose makes it easier to mask in powders and gummies than root-only extracts.
Formulation notes
Commonly combined with L-theanine, magnesium, or rhodiola in stress and sleep stacks; leaf-inclusive extracts are sometimes avoided by brands that prefer root-only positioning.
- Not for pregnancy
- Restricted in some countries
