Thorne Adrenal Cortex – Adrenal Gland Support for Stress, Fatigue & Cortisol Balance

Thorne Adrenal Cortex provides a freeze-dried, decorticated (cortisol-removed) bovine adrenal cortex extract to support healthy adrenal gland function. The adrenal glands produce hormones including cortisol, DHEA, and aldosterone that regulate stress response, energy, blood pressure, and immune function. This supplement is used by practitioners for adrenal fatigue, HPA axis support, and hormonal balance — particularly in people experiencing chronic stress or burnout.

Frequently Asked Questions

What does Thorne Adrenal Cortex do?

It supports the adrenal glands — the stress-response glands located above the kidneys — by providing adrenal cortex-derived peptides and hormonal precursors. It is used to support people experiencing adrenal fatigue, chronic stress, HPA axis dysfunction, and low cortisol symptoms.

What is adrenal fatigue?

Adrenal fatigue is a term used to describe a collection of symptoms — including persistent fatigue, difficulty waking, low stress tolerance, brain fog, and salt cravings — that may be linked to suboptimal adrenal gland function following prolonged stress. It is not universally recognised as a medical diagnosis, but many practitioners use adrenal glandular supplements for these symptoms.

Does Thorne Adrenal Cortex contain cortisol?

No. Thorne Adrenal Cortex is decorticated, meaning the cortisol has been removed. This makes it safer for long-term use than non-decorticated adrenal glandular products, which may contain variable amounts of active cortisol.

How do I take Thorne Adrenal Cortex?

Typical dosing is 1–2 capsules in the morning and/or early afternoon. Avoid taking late in the day as adrenal stimulation may affect sleep. Follow your practitioner's guidance for personalised dosing.

Is Thorne Adrenal Cortex suitable for vegetarians?

No. Thorne Adrenal Cortex is derived from bovine (cow) adrenal glands and is not suitable for vegetarians or vegans.
