Why Care About Cortisol Levels?
Briefly: increased cortisol is not only stress, but also a source of immunity, digestion, skin and hormone imbalances. This article will help you understand how cortisol works, how to control it, and what supplements are most effective for restoring inner peace and energy.
Cortisol is a stress hormone produced by the adrenal cortex in response to physical or emotional stress. Although its short-term upswings help to adapt to challenges, chronic cortisol excess has serious health consequences - from obesity, fatigue to visible external changes, the so-called "cortisol face" features.
What is cortisol and why is it important?
Cortisol regulates:
- Stress response
- Blood glucose levels
- Blood pressure
- Immune system activity
- Sleep-wake cycle
However, persistently high cortisol levels cause catabolism (muscle breakdown), accumulation of abdominal fat, hormonal imbalance, weakening of the digestive and immune systems.
Signs of elevated cortisol
✔️ Chronic fatigue, even after sleep
✔️ Anxiety, irritability, mood swings
✔️ Accumulation of fat around the abdomen
✔️ Poor sleep or early awakening
✔️ Decreasing muscle mass, especially in the limbs
✔️ High blood pressure and glucose levels
✔️ Weak immunity, frequent illness
✔️ Desire for sweets, emotional overeating
✔️ Irregular menstrual cycle, decreased libido
What is the "cortisol face"?
"Cortisol face" cortisol face) is a term used to describe changes in appearance associated with increased levels of cortisol in the body:
🔸 Rounding of the face ("moon face")
🔸 Swelling, fluid retention
🔸 Accumulation of fat in the neck and jaw areas
🔸 Dark circles under the eyes
🔸 Skin thinning, acne, redness
These signs are usually seen in the disease Cushing's syndrome, but chronic stress and poor nutrition can also cause similar symptoms.
Supplements that lower cortisol levels
1. Ashwagandha (Withania somnifera)
✔ An adaptogen that reduces stress levels and cortisol levels
✔ Improves sleep, helps concentration
✔ Popular form: KSM-66®
Recommendation: 300-600 mg per day
2. Rhodiola rosea (Rhodiola root extract)
✔ Helps the body adapt to physical and emotional stress
✔ Reduces fatigue and cortisol levels, increases energy
Dosage: 200-400 mg in the morning
3. Phosphatidylserine
✔ Reduces cortisol released during exercise
✔ Useful for those who exercise and suffer from anxiety disorders
Dosage: 300-400 mg per day
4. Magnesium (especially in the form of bisglycinate)
✔ Depresses the sympathetic nervous system (fight or flight mode)
✔ Calms, improves sleep, reduces the effects of cortisol
Dosage: 200-400 mg in the evening
5. L-Theanine (from green tea)
✔ Stimulates alpha wave activity in the brain
✔ Improves the sense of calm without sedation

6. Omega-3 fatty acids (EPA/DHA)
✔ Reduces inflammation and normalizes cortisol release
✔ Useful for the heart, mental activity, hormonal balance
Dosage: 1-3g EPA/DHA daily
7. GABA (gamma-aminobutyric acid)
✔ A natural neurotransmitter that reduces the activity of the nervous system
✔ Promotes deep sleep, reduces anxiety
Dosage: 250-500 mg at bedtime
Lifestyle recommendations
In addition to supplements, the following habits are essential to lowering cortisol:
- Quality sleep (7-9 hours per night)
- Moderate intensity physical activity
- Breathing exercises, Yoga Nidra, meditation
- Limiting sugar and caffeine
- Regular eating rhythm
- Protein for breakfast, avoid fasting under stress
What is the difference between the cortisol-lowering adaptogens Ashwagandha and Rhodiola?
Ashwagandha (Withania somnifera) works soothingly, reduces hyperactivity of the nervous system and slowly, steadily lowers cortisol levels. Especially useful for people with insomnia, chronic stress, I'm tired or anxiety. Best for use in the evening, before bed.
Rhodiola rosea have stimulating, tonic effect, improves faster physical and mental resistance to stress, but also reduces cortisol spikes, especially those associated with physical exertion. It is best to consume in the morning or the first part of the day.
Differences:
- Ashwagandha – calms and stabilizes, slower effect, more for hormonal balance
- Rhodiola – activates and tones, faster effect, useful for athletes and mental work
How does cortisol imbalance affect women's menstrual cycle and skin condition?
Elevated cortisol suppresses pituitary signals ovaries, reduces luteinizing hormone (LH) and follicle-stimulating hormone (FSH) production. As a result:
- The cycle becomes irregular or disappears altogether (amenorrhea)
- Decreases progesterone and estrogen quantity
- Increasing androgens level that causes acne, increase in oily skin, hair loss
Skin changes:
- Acne in the area of the jaw, chin
- Skin sensitivity, redness
- Inflammatory reactions (due to reduced immunity)
- Slowed wound healing
Can I take multiple cortisol-lowering supplements at the same time, and which combinations are most effective?
yes, it is possible and even recommended to combine certain supplements if they work by different mechanisms. It is only important to follow the dosage and time recommendations.
The most effective combinations:
Ashwagandha + magnesium bisglycinate
→ For the evening, a perfect combination for sleep, nervous system, hormonal balance.
Rhodiola + omega-3
→ In the morning, for physical resistance, concentration, reduction of inflammation.
L-theanine + phosphatidylserine
→ In case of anxiety or mental burnout, during work or in the evening.
Ashwagandha + GABA
→ In the evening, when there is tension, heart palpitations, it is difficult to fall asleep.
Important: Avoid an excess of adaptogens (no more than 2 different ones per day).
Each person's body reacts individually - start with a lower dose.
About cortisol and the effectiveness of supplements
Which supplements have the fastest effect - within hours or days?
Quickly (within 30 minutes - 3 hours):
- L-theanine – affects the nervous system extremely quickly, calms and reduces cortisol. Suitable for situational stress, anxiety.
- GABA – quickly relaxes, reduces the feeling of anxiety and cortisol spikes.
- Phosphatidylserine - reduces cortisol levels after physical or emotional stress within a few hours.
- Magnesium (especially bisglycinate or threonate) - within 1-3 hours can reduce muscle tension, pulse, promote parasympathetic relaxation.
Medium duration (2-7 days):
- Ashwagandha (KSM-66 or Sensoril®) - the effect is felt after a few days, but the full effect - after 2-4 weeks.
- Rhodiola rosea - the tonic effect can appear already after the first dose, but the full adaptogenic effect develops within a week.
Long-term (2-4 weeks or more):
- Adaptogenic Blends (eg Reishi, Cordyceps) – gradually improves HPA axis function, but the effect is not immediate.
- Omega-3 (EPA/DHA) – suppresses inflammatory processes, but the effect on cortisol is evident only after a few weeks.
Do you need to cycle the use of adaptogens - take breaks, change products?
Yes, cycling is recommended for the following reasons:
-
To avoid tolerance:
Long-term use of the same adaptogen may make the body less responsive to it. -
To restore the natural rhythm of the HPA axis:
Prolonged stimulation (such as Rhodiola) can have the opposite effect of exhaustion. -
Optimal cycle:
- 6-8 weeks of use
- 2-4 week breaks
- Next cycle: can continue the same or change the adaptogen
-
The best examples of rotation:
- Ashwagandha ↔ Rhodiola
- Reishi ↔ Cordyceps
- Milder options during rest cycles: Maca, Shatavari
What dietary habits enhance or weaken the effect of supplements on cortisol control?
- 🥑 Healthy fats (avocados, olive oil, eggs) → stabilizes sugar levels, suppresses cortisol spikes
- 🥦 A diet rich in fiber → supports the intestinal microflora, which modulates the activity of the HPA axis
- 🧂 Products rich in magnesium and potassium (bananas, spinach, nuts) → promotes relaxation of the nervous system
- 🥩 Protein in the morning → stabilizes sugar level and cortisol rhythm
- 💧 Hydration → even mild dehydration increases cortisol
Weakens or interferes with the effects of supplements:
- 🍬 Refined carbohydrates and sugar → causes spikes in insulin and cortisol
- ☕ Too much caffeine (especially without eating) → increases cortisol and inhibits the calming effect of adaptogens
- 🍷 Alcohol → interferes with liver function, HPA axis, reduces reserves of magnesium and group B vitamins
- 🍕 Trans fats, processed foods → causes systemic inflammation and long-term elevation of cortisol
About cortisol spikes, their influence and differential diagnosis
How do morning and evening cortisol spikes affect productivity and sleep?
Morning cortisol spike (normal, physiological):
- Helps to wake up, promotes alertness, concentration, energy.
- If too high, causes anxiety, palpitations, appetite suppression, indigestion (eg, empty stomach, nausea).
- If too low, severe fatigue in the morning, head fog, slow start, craving for coffee and sweets.
Evening cortisol spike (abnormal):
- Interferes with the production of melatonin, making it difficult to fall asleep.
- Can cause hyperactive mind, anxiety, spinning thoughts.
- Often associated with a "second wind wave" in the evening (activity after 9-10pm).
- The evening leap is often observed to constantly burnt out, overworked people.
What natural methods (without supplements) are the most effective for reducing cortisol in 10 minutes?
✅ 1. Slow diaphragmatic breathing (box breathing):
4-4-4-4 breathing (inhale-hold-exhale-hold) activates the parasympathetic system and reduces cortisol.
✅ 2. Cold washing of the face or wrists with cold water:
Immersion of the face or cold water of the hands activates the vagus nerve - reduces sympathetic tone and calms.
✅ 3. A slow walk in nature or even a short 10 min. grounding:
Walking barefoot on grass or on the ground lowers cortisol levels, especially in the morning.
✅ 4. Body relaxation techniques (progressive muscle relaxation, Yoga Nidra):
One of the most effective practices for short-term cortisol suppression without supplements.
✅ 5. A short hug or contact with a loved one/animal:
Stimulates the release of oxytocin, which suppresses cortisol.
How can you tell if high cortisol is causing fatigue or if it's an imbalance of other hormones?
Fatigue-causing high cortisol:
- Lack of energy in the middle of the day or in the evening.
- Sleep quality is poor, but falling asleep is difficult.
- It can be in the morning nervousness, but not sleepiness.
- Common symptom: craving for sweets + accumulation of belly fat.
- Often accompanied by: irritability, anxiety, indigestion, thin sleep.
Thyroid imbalance (hypothyroidism):
- Tiredness all day, even after a good night's sleep.
- Constant feeling of cold, slow digestion.
- Weight gain despite low appetite.
- Dry skin, thinning hair, weak pulse.
Estrogen Dominance/Low Progesterone (Women):
- Fatigue is cycle related (usually in phase 2).
- PMS symptoms: irritability, migraines, mood swings.
- Water retention, breast tenderness, bloating.
Insulin imbalance:
- Fatigue after eating.
- Energy "shocks" are big ups and downs throughout the day.
- A strong craving for sweets, it is difficult to endure without snacks.
An accurate way to assess is to perform a cortisol test (in saliva or blood) at different times of the day and simultaneously assess TSH, ft3, ft4, progesterone, estradiol, insulin.
7-day routine, timing of supplementation, and effects of circadian rhythms on cortisol
How to create a 7-day routine for cortisol control (morning, afternoon, evening)?
Purpose: to synchronize cortisol secretion with the natural circadian rhythm - high in the morning, low in the evening.
🕗 Eastern part (07:00 - 11:00) – cortisol activation (if too low)
- Sunlight in the eyes 10-15 minutes after waking up (outside).
- Light physical activity – stretching exercises, walking (stimulates the HPA axis).
- Cold face wash / short shower (activates the sympathetic system).
- Adaptogens for energy: Rhodiola rosea, Panax ginseng, Cordyceps.
- Caffeine - only after breakfast.
🕛 Day part (11:00-17:00) – cortisol stabilization
- A protein-rich, stable lunch (avoid sugar spikes).
- Avoid too intense training or fasting.
- If there is stress - use it breathing 4-4-4-4 or a short 5-10 min. a break.
- Extras: B vitamins, magnesium (glycinate or threonate).
🌙 Western part (18:00 - 22:00) – lowering cortisol
- Reduce screen light, blue light - use night shift.
- Slow dinner, without sugar and caffeine.
- Avoid mental activity after 9 p.m.
- Extras: Ashwagandha, L-Theanine, Phosphatidylserine, Melatonin (as needed).
The 7-day routine may be structurally the same, but you need to monitor individual reactions and use weekends as "reset" days – more sleep, less stimulation.
What supplements help in the morning when cortisol is too low and in the evening when it is too high?
☀️ In the morning (when cortisol is lacking):
- Rhodiola Rosea (200-400mg) - increases alertness, reduces fatigue.
- Panax ginseng (100-200 mg) – strengthens the tone of the HPA axis.
- Vitamin C (500-1000 mg) – important for adrenal function.
- Vitamin B5 + B6 + B12 – for energy production.
- Cordyceps sinensis – naturally activates mitochondrial energy production.
🌙 In the evening (when cortisol is too much):
- Ashwagandha (KSM-66 or Sensoril, 300-600 mg) – reduces HPA activity.
- Phosphatidylserine (100-400 mg) - directly suppresses cortisol secretion in the evening.
- L-theanine (200-400 mg) – inhibits mental hyperactivation.
- Magnesium (threonate, glycinate - 200-400 mg) - relaxes the nervous system.
- Melatonin (0.5–3 mg, only if sleep is bad) – helps to synchronize rhythms.
How do sleep and circadian rhythms affect HPA axis activity and stress hormone balance?
1. Synchronization of sleep and circadian rhythm = healthy cortisol cycle
- Cortisol naturally rises between 06:00 and 08:00 → highest level at the beginning of the day.
- Must fall by 9-10pm., to start producing melatonin and help you fall asleep.
- If you stay up late, eat late or use screens - this cycle balances out.
2. Lack of sleep = chronically elevated cortisol
- When sleeping <6 hours - increases morning and evening cortisol, rises inflammatory markers.
- This leads to accumulation of abdominal fat, insulin resistance and anxiety.
3. Going to bed late / "night life" = inverted cortisol cycle
- In the evening, energy jumps up (high cortisol) and in the morning there is a "state of zero".
- Often occurs: difficulty falling asleep, difficulty getting up in the morning, lost hunger-satiety cycle.
4. Quality of sleep is more important than quantity
- Even if you sleep for 8 hours, but falls asleep late or with frequent awakenings - the cortisol rhythm will be skewed.
What should you know before you start?
- Before starting to use several supplements at the same time, it is useful to consult a specialist.
- It is recommended to perform a cortisol test in the morning and in the evening (saliva or blood) to assess your daily rhythm.
- Prioritize: Sleep, stress reduction and regularity are more important than supplements.
