Ashwagandha
Ashwagandha (Withania somnifera)
The most clinically validated adaptogen. Ashwagandha has strong evidence for reducing cortisol, improving stress tolerance, enhancing sleep quality, boosting testosterone, and supporting thyroid function. Used for over 3,000 years in Ayurvedic medicine.
How Ashwagandha Works
Ashwagandha's withanolides modulate the HPA axis, reducing cortisol production. It also enhances GABAergic signaling (promoting calm), supports thyroid hormone conversion, and acts as an antioxidant and anti-inflammatory.
📊 Evidence by Outcome
Multiple RCTs show 23-30% reduction in cortisol levels. Meta-analysis confirms significant stress and anxiety reduction.
