What is Ashwagandha?
Ashwagandha is a traditional Ayurvedic herb classed as an adaptogen—a plant that helps the body adapt to physical and emotional stressors and maintain balance (homeostasis). Most supplements use root extracts standardized to withanolides.
How Ashwagandha Works in the Body
HPA Axis & Cortisol Modulation
Adaptogens like ashwagandha act on the HPA axis (hypothalamus–pituitary–adrenal), helping smooth cortisol peaks so you feel calmer and more resilient.
Neurotransmitter Balance
Emerging research suggests ashwagandha can influence GABAergic signalling and oxidative stress pathways, supporting calm focus without sedation.
Inflammation & Recovery
Antioxidant and anti-inflammatory actions may support joint comfort, exercise recovery, and general wellbeing.

2) Sleep Quality & Wind-Down
