What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

  • Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
  • Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
  • Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
  • No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

  • Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
  • Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
  • Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

  • Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.

The bottom line

Adrenal extract is a glandular supplement made from the adrenal glands of animals, and it is marketed mainly for fatigue and so-called "adrenal fatigue." There is no good scientific evidence that it works, and "adrenal fatigue" is not a recognized medical diagnosis. Because of possible safety and contamination concerns, talk with your pharmacist or doctor before trying it.

Overview

Adrenal extract is a type of glandular supplement. It is made from the adrenal glands of animals such as cows, pigs, or sheep. The adrenal glands sit on top of the kidneys and normally make hormones like cortisol and adrenaline that help the body handle stress.

The idea behind taking adrenal extract is that giving your body animal adrenal tissue might "support" or "boost" your own adrenal glands. It is sold as capsules, tablets, or powders, sometimes alone and sometimes mixed with vitamins, herbs, or other glandular products.

It is most often marketed for tiredness and a popular concept called "adrenal fatigue." It is important to know that "adrenal fatigue" is not a condition recognized by mainstream medicine.

How it works

Marketers claim that animal adrenal tissue contains hormones and nutrients that can refresh or support your own adrenal glands. This idea is often based on the older theory that "like supports like" — that eating an organ helps the matching organ in your body.

This proposed mechanism is not well supported by modern research. There is little reliable evidence on what active compounds survive digestion or what they actually do in the body.

One real concern is that some adrenal products may contain actual adrenal hormones (such as cortisol-like steroids). If present, these could affect the body in unintended ways. Because supplements are not tightly regulated, the true contents and strength can vary a lot from product to product.

Safety & precautions

Adrenal extract is not well studied for safety. Because it is made from animal glands, there are concerns about contamination and, in theory, the spread of animal-borne diseases. Product quality and contents are not closely controlled.

People who should be especially cautious or avoid it include those with high blood pressure, diabetes, heart disease, autoimmune conditions, or hormone-sensitive problems. Anyone with real adrenal or thyroid disease should not self-treat with glandular supplements and should work with a doctor instead.

Pregnancy and breastfeeding: There is not enough information to call this safe. To be cautious, avoid adrenal extract if you are pregnant or breastfeeding.

Always talk with your pharmacist or doctor before starting adrenal extract, especially if you take other medicines or have a chronic health condition.

Side effects

Because adrenal extract has not been carefully studied, its full side-effect profile is not known. Reported or possible effects include nervousness, a racing heartbeat, trouble sleeping, headache, and increases in blood pressure, especially if the product contains steroid-like hormones.

Some people may have stomach upset or allergic reactions to the animal-based ingredients. Rarely, glandular products could carry contaminants. Stop the product and seek medical care if you notice a rash, swelling, trouble breathing, chest pain, or other concerning symptoms.

Adrenal Extract: Reported Adverse Effects

Documented safety reports on Adrenal Extract from the evidence-graded Natural Medicines (TRC Healthcare) database, shown word-for-word from the licensed record.

Reports by condition
Encephalitis Other

Adrenal extracts are derived from raw cow, pig, or sheep adrenal glands gathered from slaughterhouses and possibly from sick or diseased animals. Products made from contaminated or diseased organs might present a human health hazard. There is also some concern that adrenal extracts produced from cows in countries where bovine spongiform encephalitis (BSE) has been reported might be contaminated with diseased tissue. Countries where BSE has been reported include Great Britain, France, The Netherlands, Portugal, Luxembourg, Ireland, Switzerland, Oman, Belgium, and others; however, there have been no reports of BSE transfer to humans from contaminated adrenal extract products. Until more is known, tell patients to avoid these products unless country of origin can be determined. Patients should avoid products that are produced in countries where BSE has been found.

Dosing

There is no established or standardized dose for adrenal extract. Products vary widely in their source, strength, and ingredients, so there is no reliable "correct" amount.

If you choose to use it despite the limited evidence, follow the directions on the product label and do not take more than recommended. It is best to check with your pharmacist or doctor first so they can review your health history and other medicines. Choosing brands that use independent third-party testing may help with quality, but it does not guarantee that the product works.
