Before you believe
Another supplementthat promises everything?
You have every right to be skeptical. The market is full of powder in pretty packaging and promises without a source.
That's why this page is different: every ingredient below comes with a dose from a specific study and a link you can open yourself. If something has no source, it isn't here.

The evidence
7 ingredients. Each with a source.
Stress and the cycle feed each other.
Your body reacts to everything the same way, it gets stressed. Whether it's work, an argument, or just bad sleep. And when stress is high in the evening, you can't fall asleep, you crave sugar, and you wake up as if you hadn't slept at all.
And if this keeps happening, sleep deteriorates, the cycle shifts, and PMS gets harder. It's not in your head. There's an explanation.
1
Stress
Work, family, social feeds, the body reads them all the same way.
2
Bad sleep
In the evening the brain won't stop. You sleep 8 hours and still get up tired.
3
Sugar cravings
At 3 pm all you can think about is chocolate. The body wants quick energy — that's all.
4
Harder PMS
A few days before your cycle everything flips. It's normal, but that doesn't mean it can't be eased.

2000 mg — the dose from studies in women.
Myo-inositol · for sugar cravings, PMS and the cycle
Ever wondered why you crave sugar just before your cycle? The body handles sugar differently on certain days of the month. It's not willpower. That's why the sachet contains myo-inositol 2000 mg, the dose studied in trials with women.
In studies with women, better handling of sugar and lighter symptoms before the cycle are observed. That's why it's the first ingredient in Corti-Glow, not because it's trendy, but because it has the most evidence specifically in women.

Magnesium bisglycinate · 670 mg (134 mg elemental Mg, 36.5% RDI)
It's not about the hours, it's about whether the body actually recovers. Magnesium helps the muscles relax and the brain stop racing. It prepares the body for real rest without forcing sleep.
Why bisglycinate specifically? Because it reaches the brain and doesn't irritate the stomach. Magnesium oxide from the pharmacy is much harder to absorb and can cause discomfort. Bisglycinate is magnesium bound to glycine, which is why the stomach handles it easily.

Ashwagandha · 300 mg · root extract
In the study, 60 participants took 600 mg of ashwagandha daily (300 mg twice) for 8 weeks. Serum cortisol dropped on average by 32.6%. The effect builds gradually — the difference shows after a few weeks.
We want to be honest about two things. First: the study is randomized, double-blind, with predominantly female participants. Second: Corti-Glow has 300 mg of ashwagandha per sachet, half the clinical daily dose. This is calibrated for long-term evening use in women, with lower risk of over-stimulation.

The verdict
What we do NOT promise.
- It does not cure insomnia, anxiety or PMS. It is a food supplement, not a medicine.
- It does not work the same for everyone. The doses come from studies, but your body is not a statistical average.
- It does not replace sleep, movement, or seeing a doctor when one is needed.
