Licorice root is an underrated natural energy booster for people struggling with persistent low energy, chronic fatigue, and daily tiredness that sleep alone cannot fix. As a herbal pharmacist, I always tell clients: if you’re constantly relying on coffee, energy drinks, or sugar to get through the day, licorice offers a healthier, root-cause solution to restore steady, sustainable energy without jitters or crashes.
Most low-energy issues aren’t caused by lack of sleep alone. More often, they stem from stressed adrenal glands, unbalanced cortisol, chronic gut inflammation, and slow nutrient absorption. While stimulants only force temporary alertness, licorice repairs the internal systems that keep your body energized long-term.

Why You Have Constant Low Energy (The Hidden Causes)
Many people feel drained all day no matter how many hours they sleep. This kind of unshakable low energy usually comes from two overlooked internal problems:
First, adrenal and cortisol burnout. Long-term stress exhausts your adrenal glands, flattening daytime cortisol levels and creating daily energy crashes. Your body simply cannot produce enough steady energy to sustain you through the day.
Second, chronic gut inflammation and poor digestion. If your stomach and intestinal lining are irritated, your body cannot fully absorb nutrients from food. Even if you eat well, you’re essentially “malnourished at the cellular level”, leading to persistent tiredness, body heaviness, and low stamina.
Caffeine and sugar only mask this fatigue temporarily. Licorice fixes both core issues simultaneously.
Real Client Case: Licorice Fixed Years of Constant Low Energy
Here is a very common low-energy recovery case I see regularly in my herbal consultations:
A 36-year-old female client came to me with over two years of persistent low energy. She slept 7–8 hours every night but still woke up exhausted. She relied on two cups of coffee daily just to function, crashed hard every afternoon, and felt physically weak and mentally foggy by evening. Blood work ruled out thyroid problems, anemia, and vitamin deficiencies—her fatigue was purely stress and inflammation-induced.
I recommended cycled morning usage of standard licorice root (not DGL) to support adrenal function, paired with no extra caffeine after noon. Within 2 weeks, her morning fatigue improved significantly, and her afternoon energy crashes became far less severe. After 5 weeks of consistent use, she no longer needed daily coffee, her energy stayed stable all day, and her overall stamina returned completely. Licorice helped her body produce its own natural energy again.
How Licorice Root Boosts Low Energy (Pharmacist Breakdown)
Licorice works differently from stimulant-based energy supplements. It revives your energy by repairing your body’s fatigue triggers in three key ways:
1. Stabilizes cortisol and adrenal function
Licorice’s active compound glycyrrhizin prevents rapid cortisol breakdown, maintaining healthy daytime hormone levels. This eliminates the flat, drained feeling caused by low cortisol and fatigued adrenals, supporting consistent all-day energy without artificial stimulation.
2. Reduces chronic inflammation that drains energy
Hidden systemic and gut inflammation is a major silent energy drain. Your body wastes massive amounts of energy fighting low-grade inflammation daily. Licorice’s strong anti-inflammatory properties calm internal irritation, freeing up your body’s energy reserves for daily stamina and cellular function.
3. Improves nutrient absorption and digestive efficiency
By repairing and protecting the gut mucosal lining, licorice boosts nutrient absorption from your meals. Better digestion means more vitamins, minerals, and energy substrates reach your cells, eliminating the “sleepy after eating” and constant bodily heaviness linked to poor digestion.
Regular Licorice vs DGL for Low Energy
This is the key difference most people miss when trying to fix fatigue:
DGL licorice will not improve chronic low energy.
DGL removes glycyrrhizin to focus solely on gut repair for reflux, gastritis, and ulcers. But glycyrrhizin is the exact compound that supports adrenal health, cortisol balance, and energy restoration.
For low energy and fatigue recovery, always use standard full-spectrum licorice root, not DGL.
That said, standard licorice requires cycled usage to avoid side effects—long-term uninterrupted daily use is not recommended.
Pharmacist-Recommended Routine for Low Energy
Follow this safe, energy-boosting protocol for steady fatigue recovery:
Take standard licorice root extract or mild tea before 10 AM (morning only).
Morning intake supports healthy daytime cortisol and energy levels without disrupting nighttime sleep rhythm. Avoid afternoon or evening use.
Cycle schedule: Use daily for 4–6 weeks, then take a 1–2 week break to prevent glycyrrhizin buildup.
Best pairing: Combine with B vitamins and magnesium for maximum cellular energy and stress relief.
Who Should Avoid Licorice for Energy Support
Avoid standard licorice root if you have any of the following conditions:
- High blood pressure or hypertension
- Heart palpitations or cardiac conditions
- Kidney dysfunction
- Low potassium levels
- Pregnancy or breastfeeding
- Clinically high cortisol or Cushing’s syndrome
- Blood pressure medications or diuretics
FAQs (Licorice for Low Energy Common Questions)
Q: Does licorice give you instant energy like coffee?
A: No. Licorice is an adaptogen, not a stimulant. It doesn’t create jittery artificial energy. Instead, it gradually restores your natural stamina, eliminating fatigue long-term.
Q: How fast does licorice improve low energy?
A: Most people feel more stable daytime energy and fewer afternoon crashes within 1–2 weeks. Full fatigue recovery and consistent all-day stamina take 4–6 weeks of proper cycled use.
Q: Why does DGL not work for tiredness?
A: DGL lacks glycyrrhizin, the compound responsible for adrenal support and cortisol balance. Without it, no energy-boosting or fatigue-repairing effects occur.
Q: Can licorice fix fatigue caused by stress burnout?
A: Yes. It’s extremely effective for stress-induced low energy, adrenal exhaustion, and burnout-related persistent tiredness.
Q: Is long-term daily licorice safe for energy?
A: No. Always cycle usage to avoid blood pressure and electrolyte imbalances.
Final Herbal Pharmacist Verdict
Licorice root is one of the best natural adaptogens for beating chronic low energy and stress fatigue. Instead of relying on caffeine and sugar that drain your body further, it repairs fatigued adrenals, balances your stress hormones, and optimizes digestion to restore your body’s own natural energy reserves.
If you struggle with unshakable daily tiredness, morning grogginess, and afternoon energy crashes that never fully go away, properly cycled morning licorice use is a gentle, sustainable solution for long-term energy recovery.
