Stress is something everyone experiences, sometimes without even realizing it. For some, it's a one-off, but for others, it becomes chronic. And behind this feeling of constant pressure lies a key hormone: cortisol .
Secreted by the adrenal glands, this hormone plays a vital role in our survival. It gives you the energy you need to react quickly in times of danger: fleeing from a bear, passing a surprise exam, or surviving an unscheduled meeting. But when these levels remain elevated for too long , the effects can be detrimental to your health.
The Role of Cortisol in Your Body
Think of cortisol like a fire alarm: It's essential in an emergency, but if it's ringing continuously, that's when the trouble starts.
Chronically high levels of cortisol can cause:
- An increase in blood sugar levels , which can lead to long-term insulin resistance.
- Chronic fatigue , because cortisol disrupts energy production and can disrupt deep sleep.
- Loss of muscle mass and increased fat storage , due to a pronounced catabolic effect.
Anti-stress supplements to the rescue?
This is where some natural solutions come into play. Two main supplements stand out in stress management based on my experience and trial and error:
1. Ashwagandha
This adaptogenic herb is widely studied for its cortisol-lowering effects. Clinical studies show that regular intake of ashwagandha can reduce cortisol levels by 14–30% in stressed individuals*.
- Recommended dosage : 300 to 600 mg of standardized extract (with 5% withanolides) per day.
- Should you cycle ashwagandha? Yes! Ashwagandha can be taken for 6 to 12 weeks, followed by a few weeks off to prevent habituation and maintain its effectiveness.
2. Theanine
This amino acid, naturally present in green tea, is known for its effects on the balance between dopamine, serotonin, and GABA. It helps relax the brain without causing drowsiness, making it useful for daytime stress management.
- Recommended dosage : 100 to 200 mg per day.
- Where can I find it? As a supplement or also used in some natural energy drinks like Guru, to provide stimulation without the jitters often associated with caffeine.
Are these supplements for everyone?
While effective, these supplements are not miracle solutions. They must be integrated into a comprehensive approach that includes good sleep management, a balanced diet, and regular physical activity.
So, can anti-stress supplements transform your daily life? Maybe not overnight, but they can certainly give you a big boost in stress management and optimizing your recovery. Your body and mind will thank you.
👉 One last tip : Before adding any supplement to your routine, consult a healthcare professional. Every body is unique, and the approach should be tailored to your hormonal profile and stress levels.
