Adaptogens

Evidence-informed definition Updated September 23, 2026 How to cite this entry

Adaptogens are natural substances, often herbs, that help the body adapt to stress and maintain balance. They regulate stress response systems, protecting against chronic stress’s negative effects. Examples include Rhodiola Rosea, Ashwagandha, and Ginseng, which are traditionally used for stress reduction and resilience.
