The word “adaptogen” gets thrown around supplement marketing with the same precision as “superfood” — which is to say, imprecisely. As a science teacher, I’ve developed strong allergies to hype without mechanism. So let me try to give you the actual science on three popular adaptogens, including both what the evidence supports and where the gaps are.
What Is an Adaptogen?
The term was coined by Soviet pharmacologist Nikolai Lazarev in 1947, later formalized by Brekhman and Dardymov (1969). An adaptogen is defined by three criteria: it must be non-specific (increase resistance to a wide range of stressors), normalize physiological functions (raise what is low, lower what is high), and be non-toxic at normal doses.[1]

The mechanistic plausibility centers on HPA axis (hypothalamic-pituitary-adrenal) regulation — the cortisol stress response system. Adaptogens are proposed to modulate this system, reducing the amplitude of the stress response without eliminating it.
My take: the research points in a clear direction here.

Ashwagandha (Withania somnifera)
Probably the best-studied of the three in human trials.
