Ashwagandha Root Extract

Reviewed by the Nimbera editorial team · Last updated May 2026

A randomized, double-blind, placebo-controlled trial found ashwagandha supplementation significantly increased free testosterone and luteinizing hormone in aging overweight males compared to placebo.$20-$45 per month

How to use

Take 300-600 mg of standardized root extract (KSM-66 or Sensoril) daily, typically split into two doses with meals. Most trials run 8-12 weeks before measuring results.

How it works

Ashwagandha is classified as an adaptogen - it lowers cortisol, which at chronically elevated levels suppresses the hypothalamic-pituitary-gonadal axis. By reducing cortisol, it may allow the body to restore normal luteinizing hormone signaling and testosterone production.

Where to buy

Health food stores, iHerb, Amazon - look for KSM-66 or Sensoril branded extract with standardized withanolide content (5% or higher).

Typical cost: $20-$45 per month
