As a Nutritional Therapy Consultant, one of my specialist areas is helping people recover from adrenal fatigue, chronic exhaustion, and unexplained low energy.
Many people feel tired most of the time and simply accept it as “normal” — but persistent fatigue is not normal, and it’s often a sign that the adrenal glands are struggling to cope with long-term stress.
In this article, I’ll explain:
- What adrenal fatigue is
- Common symptoms
- What causes it
- How to restore energy naturally through nutrition, lifestyle, supplements, and nervous system support
What Is Adrenal Fatigue?
Adrenal fatigue refers to a functional imbalance of the adrenal glands, where they struggle to produce adequate levels of stress hormones — particularly cortisol.
While adrenal fatigue is not considered a formal medical diagnosis, it is widely recognised in functional and nutritional medicine as a contributor to ongoing fatigue, poor stress tolerance, disrupted sleep, and hormone imbalance.
Symptoms of Adrenal Fatigue
Common adrenal fatigue symptoms include:
- Persistent low energy
- Feeling exhausted upon waking
- Difficulty handling stress
- Feeling overwhelmed or “burnt out”
- Low blood sugar symptoms
- Brain fog and poor concentration
- Mild anxiety or low mood
- Cravings for caffeine, sugar, or salt
- Frequent colds or low immunity
- Digestive problems
- Low body temperature
- Increased abdominal fat
If several of these symptoms resonate, adrenal fatigue may be playing a role.
The Role of the Adrenal Glands
The two adrenal glands sit above the kidneys and secrete over 50 hormones that regulate:
- Energy production
- Blood sugar balance
- Stress response
- Immune function
- Blood pressure
- Fluid and electrolyte balance
- Sex hormone production
Cortisol and Energy Regulation
Cortisol is one of the most important adrenal hormones. Its functions include:
- Regulating blood glucose
- Mobilising fat and protein for energy
- Supporting blood pressure and heart rate
- Influencing brain function and immune response
Cortisol Rhythm and Adrenal Fatigue
Cortisol follows a daily circadian rhythm:
- Lowest: midnight – 4am
- Highest: 6am – 8am
- Gradually declines throughout the day
In adrenal fatigue, this rhythm becomes disrupted, often leading to:
- Morning exhaustion
- Afternoon energy crashes
- A “second wind” late at night
Typical Adrenal Fatigue Energy Pattern
- Morning fatigue
- Slight improvement after midday
- Energy dip between 2–4pm
- Improvement after 6pm
- Wired but tired feeling after 11pm
Does this sound familiar?
What Causes Adrenal Fatigue?
Adrenal fatigue develops due to chronic stress exposure, including:
- Psychological stress (work, family, emotional strain)
- Over-exercising or under-recovering
- Poor diet and nutrient deficiencies
- Blood sugar instability
- Excess caffeine, alcohol, or sugar
- Chronic inflammation
- Poor sleep quality
- Digestive dysfunction
Over time, the constant demand for stress hormones leaves the adrenals unable to keep up.
Testing for Adrenal Function
Conventional medicine often uses blood cortisol tests to rule out conditions such as Cushing’s Syndrome or Addison’s Disease.
In functional medicine, we use a salivary Adrenal Stress Profile, which measures cortisol levels at multiple points throughout the day. This provides a far more accurate picture of daily adrenal function and hormone patterns.
How to Treat Adrenal Fatigue Naturally
1. Improve Your Diet
Nutrition is foundational to adrenal recovery.
Key principles:
- Eat small, regular meals
- Balance protein, fats, and complex carbohydrates
- Avoid blood sugar spikes
Focus on:
- Lean proteins
- Whole grains
- Healthy fats
- Plenty of vegetables
Avoid:
- Refined sugar
- Ultra-processed foods
- Excess caffeine and alcohol
2. Improve Sleep Quality
Sleep is critical for adrenal repair.
- Cortisol should be lowest overnight
- Disrupted rhythms cause poor sleep and morning fatigue
Tips:
- Create a calming bedtime routine
- Avoid screens close to bedtime
- Try meditation, breathing exercises, gentle yoga, or reading
3. Balance Blood Sugar Before Bed
Low cortisol can lead to night-time blood sugar dips, waking you from sleep.
A small bedtime snack may help, such as:
- Avocado on a wholegrain cracker
- A boiled egg
- Mixed nuts
- Wholegrain toast with nut butter
4. Targeted Supplements for Adrenal Support
Diet alone is often not enough during adrenal fatigue due to impaired nutrient absorption.
Key supplements include:
Vitamin C
Highly concentrated in the adrenal glands and essential for cortisol production. Stress increases vitamin C demand.
B Vitamins
Especially vitamin B5, which supports energy production and adrenal hormone synthesis.
Magnesium
Essential for nervous system regulation, relaxation, and adrenal function.
Adaptogenic Herbs
Help the body adapt to stress:
- Ashwagandha
- Rhodiola
- Siberian Ginseng
- Liquorice root
Ashwagandha has been shown to improve stress resilience and cortisol balance.

Supporting Energy Through the Nervous System: Nurosym Device
Adrenal fatigue is closely linked to nervous system dysregulation, particularly reduced vagal tone.
The Nurosym device supports energy and recovery by stimulating the vagus nerve, helping to shift the body out of chronic “fight or flight” mode and into a state of rest and repair.
Benefits may include:
- Improved energy levels
- Reduced stress and anxiety
- Better sleep quality
- Improved resilience to stress
