Background

Adrenal extracts are derived from the adrenal glands of cows, pigs, or sheep gathered from slaughterhouses. The adrenal glands, which are above the kidneys, secrete adrenal hormones. The adrenal medulla secretes epinephrine (adrenaline) and norepinephrine (noradrenaline) while the adrenal cortex secretes a group of hormones called corticosteroids.
Adrenal extracts have been used medicinally since 1931, primarily in the injectable form. Today, adrenal extract is available only in the form of capsules or tablets. Commercially available adrenal extracts are made from the whole gland (whole or total adrenal extracts) or just from the outer part of the gland (adrenal cortex extracts). Although adrenal extract has been used to treat fatigue and low adrenal function, currently no human trials of adrenal extract have been performed to support these claims.

Tradition / Theory

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Dosing

Adults (18 years and older)
There is no proven safe or effective dose for adrenal extract. Commercially available adrenal extracts are made from the whole gland (whole or total adrenal extracts) or just from the outer part of the gland (adrenal cortex extracts).

Safety

The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.
