Evidence Strength

3/5 — Moderate
EvidenceModerate

Moderate evidence. Multiple RCTs show benefits for cortisol reduction, anxiety, and sleep. Long-term safety data is limited. Cycling recommended.

Overview

Take 300-600mg of KSM-66 ashwagandha root extract daily. This adaptogen has been shown to reduce cortisol, anxiety, and improve sleep quality and testosterone levels in multiple clinical trials.

Wellness education and routine support only. Review the evidence, caveats, and interactions before trying this protocol, and ask a clinician when medical conditions, pregnancy, medications, or symptoms are involved.

How To Do It

  1. 1

    Choose KSM-66 extract

    KSM-66 is the most clinically studied extract. Full-spectrum root extract.

  2. 2

    Start with 300mg/day

    Take in the evening. Increase to 600mg if well-tolerated.

  3. 3

    Cycle usage

    8 weeks on, 2 weeks off. Long-term continuous use is not well-studied.

The Evidence

Each claim is linked to its source study. Confidence reflects the study design — systematic reviews and RCTs rank highest.
