Proponents believe so, though more research is needed. Adaptogens may do for your adrenal glands what exercise does for your muscles, Powell says. “When we exercise, it’s a stress on our body. But as we continue to train and exercise, our body becomes better at dealing with the stress of it, so we no longer get as tired or as high a heart rate,” she says. When you take adaptogens, meanwhile, “you’re training your body to handle the effects of stress.”
