Supplements for stress
Stress isn't in your head.
It's in your blood.
Cortisol is a hormone. It can be measured with a blood test. When it's chronically elevated, neither meditation nor "positive thinking" fix it. What helps is addressing it directly, with ingredients that have clinical data.
Available today, for stress
The ashwagandha carries a stated root-extract dose per capsule. Magnesium contributes to normal nervous system function. Others make them, we sell them.
The vicious cycle you don't see
When cortisol is high in the evening, the brain can't fall asleep. When you don't sleep enough, cortisol is even higher in the morning. The result: fatigue, irritability, afternoon sugar cravings, poor sleep, and back to start.
Evening
High cortisol, you can't fall asleep. You toss, think about tomorrow.
Morning
You slept 5 hours. Body compensates with more cortisol. You wake up exhausted.
Afternoon
Energy crash. Reaching for sugar. Cortisol spikes again.
Not a discipline problem. The body works this way.
What the clinical studies show about cortisol
Not everything labeled "for stress" works. Here's the data:
Ashwagandha 300 mg (root extract)
Root extract, standardised to withanolides, 300 mg per sachet. Root, not leaf: the leaf is cheaper to harvest, which is why so many labels just say "ashwagandha" and leave the part out.
Corti-Glow dose: 300 mg per sachet. Study dose: 300 mg twice daily.

L-theanine 200 mg
Amino acid from green tea. Raises alpha brain waves in about 30 minutes, the frequency associated with calm focus. Doesn't sedate or stun. Just lowers tension.
Corti-Glow dose: 200 mg per sachet.
Magnesium bisglycinate 670 mg
A highly absorbable form that is gentle on the stomach — unlike pharmacy magnesium oxide, which can loosen the stomach at higher doses. Magnesium contributes to normal muscle function and normal functioning of the nervous system — authorized EU claims.
Corti-Glow dose: 670 mg per sachet (134 mg elemental Mg, 36.53% RDI).

Choline Bitartrate 250 mg
Supports normal nervous system function. Choline is a building block for cell membranes and is essential for normal neurotransmitter synthesis. Not a stimulant — it supports day-to-day nervous system maintenance.
These are the ingredients with clinical data on stress. The full Corti-Glow formula has 7 ingredients — including myo-inositol 2000 mg and L-glycine 2000 mg. All doses are on the label.
Work stress vs PMS stress, why it's more complex in women
Men have relatively stable cortisol day to day. In women, estrogen and progesterone shift every day of the cycle, directly affecting cortisol response.
Before your period
Progesterone drops sharply in the 2 weeks before your period. The body reacts like it's under threat, cortisol rises. Add a work deadline and you have a double hit.
Work stress
Chronic, predictable, but unavoidable. In the evening cortisol should drop, but in the days before your period, the body is already on high alert.
Corti-Glow was built for that reality: one sachet in the evening, seven ingredients in evening doses, and magnesium that contributes to normal nervous system function and to the reduction of tiredness and fatigue. Thirty evenings to a box, and every number on it sits on its own line.
Frequently asked questions
How fast do stress supplements work?+
L-theanine raises alpha brain waves within ~30 minutes, you feel calm without drowsiness. Ashwagandha works cumulatively: the effect on cortisol builds over 4–8 weeks of daily intake.
Can I take Corti-Glow with other medications?+
Corti-Glow is a dietary supplement with natural ingredients. If you take medication (especially for thyroid, blood pressure or antidepressants), consult your doctor before use.
Why a sachet, not a tablet?+
A sachet allows higher doses in one serving — for example 2000 mg L-glycine, 2000 mg myo-inositol and 670 mg magnesium out of the 7 ingredients total. A tablet with those amounts would be huge, you'd need 8+ capsules. Plus, you dissolve it in water and drink in the evening as a calming moment before bed, not just another pill. The magnesium bisglycinate form is gentle on the stomach.
What is bisglycinate and why not regular magnesium?+
Magnesium bisglycinate is magnesium bound to the amino acid glycine. It absorbs far better than magnesium oxide — the cheapest pharmacy form, at only ~4% absorption (Firoz & Graber, 2001) — and doesn't irritate the stomach.
Is Corti-Glow safe during pregnancy?+
No. Ashwagandha is not recommended during pregnancy or breastfeeding. If you're planning pregnancy, consult your doctor.
