Understand The Science

What Cortisol Does To Your Body

Cortisol is your body's main stress hormone. When it stays elevated, especially at night, it works against you.

What Cortisol Does To Your Body
1
Stress Response Kicks InWhen cortisol spikes, your body shifts into fight-or-flight mode — raising heart rate, blood sugar, and alertness so you can react fast.
2
Sleep & Recovery SufferElevated cortisol at night blocks the deep sleep your body needs to repair itself, leaving you groggy and puffy the next morning.
3
Long-Term Wear On The BodyChronically high cortisol contributes to water retention, stubborn fat storage, and a constant feeling of being "wired but tired."

How CortiZen Restores Your Cortisol Balance

CortiZen is a warm cacao blend that targets the effects of excess cortisol at night, in whatever form it shows up.

All clinically dosed ingredients — Reishi, L-Theanine, Magnesium and more — come together in one delicious blend you prepare in under 2 minutes as an evening ritual.

So you no longer need a cabinet full of separate supplements or pills.

The combination actively lowers your cortisol levels, calms your nervous system, and restores the biological rhythm that shifts your body from stress into recovery.

No temporary fix for a single symptom. Sleepy Siren addresses the source, so your body can heal itself.

* Based on clinical studies of CortiZen's functional ingredients at a daily dose of 1 cup. Including a double-blind, randomized, placebo-controlled study on Ashwagandha KSM-66 (300mg) in 64 participants with chronic stress and anxiety, conducted over a 60-day period.

Natural Ingredients, Scientifically Backed

Frequently Asked Questions

Is CortiZen suitable for sensitive stomachs?

Yes. Start with half a portion if you are sensitive to herbs or supplements and increase this over a few days.
Does CortiZen contain melatonin?

No, CortiZen is completely melatonin-free. This allows you to use it safely every evening without habituation.
Can I also use it if I am already taking other supplements?

In most cases, yes. However, if in doubt about combining it with medication or other supplements, it is wise to consult a professional.
When is the best time to take it?

We recommend taking the supplement 30 to 60 minutes before going to sleep. One scoop per day is ideal.
How do these ingredients work together for hormonal problems?

Hormonal fluctuations — caused by PMS, cycle stress, PCOS, or perimenopause — can lead to worrying, tension, and difficulty falling asleep.

CortiZen works in three ways:

Relaxation of the nervous system (magnesium, L-theanine)

Reduction of stress response (adaptogens)

Calming before bedtime (chamomile, passionflower)
This combination supports a natural sleep stimulus without melatonin.
Can I use CortiZen if I have a medical condition?

Even though our ingredients are natural and carefully formulated, we always recommend consulting your doctor or treating specialist first if you have a medical condition or are taking medication. This ensures that this supplement is suitable for your personal situation.
What if I feel like it isn't working?

We offer a 30-day money-back guarantee. If it doesn't feel right for your body, we'll fix it. Send your last jar back within 30 days of purchase and you get your money back. No hassle. No pressure. Just results, or your money back.
