Adrenal Fatigue: Real Struggle or Total Myth? Let’s Break It Down

Chances are you’ve heard your friends or family claim they have what they self-proclaim as “adrenal fatigue.” Now when someone confides in you about their recent health “issues,” unless you’re a practitioner, I doubt the first words out of your mouth are going to be, “Oh really, Jennifer? You’re full of sht.”* Yeah… not likely.

So we’re here today to blow the whistle on ‘adrenal fatigue’ and get to the bottom of what it really is—or isn’t. Spoiler alert: it’s probably not what you think.

In This Article, We'll Cover:

• What adrenal fatigue is (and isn’t)

• The theory behind it

• Symptoms often associated with it

• Legitimate conditions like adrenal insufficiency

• What foods and strategies can help you feel better

• Why your symptoms are real, even if the label isn’t

What Is Adrenal Fatigue?

Let’s be clear: adrenal fatigue is not a medically recognized condition.

According to Harvard Medical School, adrenal fatigue is “an attractive theory that links stress exposure to adrenal exhaustion as a possible cause of lack of energy.” In simpler terms, it’s a catch-all buzzword for feeling like crap due to stress, overwork, and life chaos—but it’s not an actual diagnosis.

“There is no scientific proof that exists to support adrenal fatigue as a true medical condition.”
— Endocrine Society

The Theory Behind Adrenal Fatigue

The adrenal glands—located above your kidneys—produce hormones like cortisol, the so-called “stress hormone.” The theory behind adrenal fatigue suggests that chronic stress burns out these glands, leaving you hormonally depleted and feeling like a zombie. Sounds logical, right?

But here’s the problem: this theory assumes your adrenals physically can’t keep up, when in reality, research shows the glands are still functioning. What's likely happening instead? You're stressed, inflamed, under-recovered, and potentially undernourished.

Symptoms People Associate with Adrenal Fatigue

Even though adrenal fatigue isn’t an official diagnosis, the symptoms people report are very real:

• Chronic fatigue

• Low mood or depression

• Anxiety

• Brain fog

• Insomnia

• Irritability

• Trouble recovering from exercise

• Cravings for salty or sugary foods

• Morning exhaustion despite sleep

“These people are suffering from something… we need to take the suffering seriously, even if the label 'adrenal fatigue' is inaccurate.”
— Dr. Lynnette Nieman, Endocrine Society

Where Did the Term Come From?

Blame it on the internet. In 1998, James L. Wilson, a chiropractor—not an MD—coined the term on his website to describe what he believed was “suboptimal adrenal function caused by stress.” While well-intended, the term lacks medical validity, and there’s no accepted lab test that can confirm it.

A comprehensive literature review published in BMC Endocrine Disorders concluded:
“There is no substantiation that adrenal fatigue is an actual medical condition.”
— Cadegiani & Kater, 2016

Is Adrenal Insufficiency Real? Yes.

Unlike adrenal fatigue, adrenal insufficiency is a medically recognized and serious condition. Often referred to as Addison’s Disease, this disorder occurs when the adrenal glands fail to produce enough hormones, especially cortisol and aldosterone.

Symptoms of adrenal insufficiency include:

• Fatigue and muscle weakness

• Weight loss

• Low blood pressure

• Nausea and vomiting

• Darkening of the skin

• Dizziness or fainting

If you suspect this, testing for cortisol levels before and after ACTH stimulation is the gold standard for diagnosis.

Adrenal Fatigue Treatment: What's the Real Fix?

There’s no pill for adrenal fatigue—because it’s not a condition. But the symptoms? Those can and should be addressed.

Step 1: See a Doctor

Don’t barrel into their office demanding an adrenal fatigue diagnosis. Instead, talk to your provider about your symptoms. Rule out actual endocrine disorders, thyroid issues, sleep apnea, or anemia.

Step 2: Address Lifestyle Factors

You’re not broken—you’re probably burnt out. The solution?

• Better nutrition

• Stress management

• Improved sleep

• Slower training load

• Reducing caffeine and alcohol

Step 3: Food First, Not Pills

You don’t need overpriced adrenal supplements or shady powders. You need micronutrients, balanced macros, and foods that support neurotransmitter production like:

• Tryptophan & Tyrosine (turkey, dairy, oats, eggs)

• Vitamin B6, Magnesium, and Folate (leafy greens, legumes, whole grains)

• Complex carbs for sustained energy

Best Diet for "Adrenal Fatigue" Symptoms

A nutrient-dense, balanced diet is your best weapon against stress-driven dysfunction. Focus on:

• High-protein meals to support recovery

• Healthy fats for hormone balance

• Complex carbs to stabilize energy

• Adaptogenic foods (like berries, green tea, and turmeric)

The Takeaway: Adrenal Fatigue Isn’t Real—But Your Symptoms Are

Here’s the truth: adrenal fatigue is a label for a deeper issue—chronic stress, poor recovery, under-eating, or underlying health concerns. Dismissing it entirely doesn’t help people who are struggling. Neither does overmedicalizing normal stress-related symptoms.

So, next time your friend Jen says she’s dealing with adrenal fatigue, don’t laugh—ask her how she’s really doing. Ask about her stress, sleep, nutrition, and workload. Because chronic burnout is real, and it deserves more than a shrug and a supplement ad.
