Adrenal hyperfunction or overactive adrenals occur when the adrenal glands produce excessive amounts of hormones, including cortisol.
All stress, good or bad, activates the hypothalamic-pituitary-adrenal (HPA) axis and the release of associated stress hormones (Anderson 2008). This is commonly known as the “fight or flight” response. The hormones (e.g., cortisol) released in this process have numerous effects on the body that are intended to provide a burst of energy and heighten alertness to deal with acute threats. For example, the body’s energy stores are mobilized; non-essential bodily functions, like digestion and reproduction, are suppressed; and the delivery of oxygen and nutrients to vital organs and muscles via the cardiovascular system is improved (Todorova 2021). When activation of the HPA axis and release of adrenal hormones becomes constant or chronic, health problems develop (Anderson 2008).
The HPA axis organs may become desensitized and damaged, leading to a “kink” in the system and an overproduction of cortisol (Anderson 2008). Chronically elevated cortisol levels have been shown to affect reproduction, growth hormone, and thyroid function (Anderson 2008). Excess cortisol can be a cause of and a result of oxidative stress, which adversely affects adrenal function. Endogenous antioxidants, including glutathione, glutathione peroxidase, catalase, and superoxide dismutase, and exogenous antioxidants, including vitamins C, E, carotenoids, selenium, and zinc, help counteract oxidative stress and protect adrenals (Patani 2023).

Adaptogen is a term applied to herbs that normalize physiology and encourage non-specific resistance to stressors (Anderson 2008). They are associated with improving the body’s ability to adapt to stress and normalizing metabolic functions (Todorova 2021). The following adaptogens are recommended:
250 mg of standardized extract once or twice daily (Stengler 2016)
125 mg of a standardized extract twice daily (Lopresti 2022)
200 mg/d of a standardized extract (Anghelescu 2018)
350 to 500 mg/d (Schutten 2020)
1 to 2 g/d (Jahangard 2019, Kiecolt-Glaser 2011)
1,000 mg two to three times daily (Stengler 2016)
25 to 200 mg/d (Kroboth 2003; Genazzi 2006; Chen 2021)
400 to 800 mg/d (Monteleone 1992, Hellhammer 2004)
