Question 1

What is the best form of Ashwagandha to take?

Accepted Answer

KSM-66 and Sensoril are the two most clinically validated ashwagandha extracts, each with multiple published RCTs. KSM-66 uses a full-spectrum root extract standardised to 5% withanolides and has the strongest evidence for stress, cortisol, and testosterone. Sensoril uses both root and leaf at 10% withanolides and has more data on sleep and anxiety. Generic 'ashwagandha root extract' without a declared withanolide percentage is harder to evaluate and less predictable in effect. Either branded extract at 300–600 mg per day is the evidence-backed approach.

Question 2

How quickly does Ashwagandha reduce stress?

Accepted Answer

Trials measuring cortisol and self-reported stress typically show statistically significant reductions after 4–8 weeks of daily use at 300–600 mg of standardised extract. Some participants report improved sleep quality within the first 1–2 weeks, which may indirectly reduce perceived stress sooner. Ashwagandha is an adaptogen — its effects build over time rather than providing immediate relief, and benefits are generally maintained while supplementation continues.
