Adrenal Cortex
Description
Adrenal cortex extract provides concentrated bovine adrenal cortex tissue, delivering naturally occurring adrenal hormones, peptides, and cofactors that support the adrenal glands during periods of chronic stress or fatigue. This type of glandular supplementation follows the principle that like supports like, providing the specific proteins and hormonal precursors the adrenal cortex needs to recover and function optimally. It is commonly used for adrenal fatigue syndromes marked by low morning cortisol, persistent exhaustion, poor stress tolerance, and salt cravings. Best used under the guidance of a functional medicine practitioner.

Commonly Referenced Amount
Independent lab analysis of commercial adrenal-support supplements has repeatedly found undisclosed thyroid hormone and steroid hormones (most often pregnenolone), unlisted on the label. 'Adrenal fatigue' is also not a recognized medical diagnosis. Given the undisclosed hormone content, we're not publishing a consumer dose here.
Referenced Upper Limit
Not applicable outside clinical or research supervision
