COMPARISON
Corti-Glow vs Melatonin
Melatonin is the best-selling sleep supplement in the world. Corti-Glow works in a completely different way. This page will help you decide which of the two is right for you — without marketing jargon.
TL;DR
Melatonin is fast and cheap — it works the first evening, ideal for jet lag or a short-term problem. Corti-Glow isn't a "sleep pill" — it's built around the stress axis and hormonal balance, for a natural wind-down. It takes 1-2 weeks, but works on the cause, not the symptom.
How do they work?
M
Melatonin
Melatonin is a hormone the brain produces when it gets dark. When you take melatonin as a supplement, you add this hormone directly from outside. The body gets the signal "time for sleep" and starts to relax.
The problem: if the cause of your insomnia is stress (high cortisol), melatonin masks the symptom without addressing the root. Cortisol stays high — you're just "forcing" the body to sleep.
CG
Corti-Glow
Corti-Glow contains 7 ingredients that work on 3 axes:
- 1.Cortisol: In a clinical trial (Salve et al., Cureus, 2019, 60 participants) 600 mg of ashwagandha daily reduced serum cortisol by 32.6% over 8 weeks. In Corti-Glow — 300 mg of ashwagandha per sachet, for long-term evening use in women.
- 2.Nervous system: Magnesium bisglycinate (670 mg / 134 mg elemental, 36.5% RDI) — contributes to normal nervous system function (authorized EU claim) — with L-theanine (200 mg).
- 3.Hormonal balance: Myo-inositol (2000 mg) — studied in women with PCOS and PMS.

| Criterion | Corti-Glow | Melatonin | Advantage |
|---|---|---|---|
| Mechanism | Works on the stress axis — ashwagandha (300 mg; Salve 2019: −32.6% serum cortisol at 600 mg/8 weeks). Magnesium contributes to normal nervous system function (authorized EU claim), with L-theanine. | Mimics natural melatonin — directly tells the brain "sleep now". | Depends |
| How fast it works | 7-14 days for first effect. Full effect after 4-8 weeks. | 30-60 minutes. Works the first evening. | Melatonin |
| Long-term use | Safe for continued use. The effect accumulates over time. | Debatable. Some doctors don't recommend it beyond 3 months. The body may reduce its own production. | Corti-Glow |

When melatonin is the better choice
Let's be honest — in some situations, melatonin is simply the more practical option:
- Jet lag: Flying from Sofia to New York? Melatonin is the gold standard for resetting the internal clock. Corti-Glow isn't designed for that.
- Night shift: If you work nights and have to sleep during the day, melatonin compensates for the missing natural signal from darkness.
- Budget: If budget is a factor and you don't have stress or hormonal issues — melatonin for 5 €/month is a perfectly acceptable option.
- Short-term problem: If you can't sleep for 3-4 days (e.g. before an exam, a stressful event), melatonin will do the job for a few evenings.
When Corti-Glow is more suitable
Corti-Glow is made for women who recognize themselves in these situations:
- Chronic stress: You wake up at 3 AM and your mind immediately starts running through the list of problems. The problem isn't melatonin — the problem is cortisol.
- PMS and PCOS: If insomnia intensifies before your period, the cause is often hormonal. The formula adds myo-inositol (2000 mg) — studied in women with PCOS — and magnesium.
- You've tried melatonin and it didn't help: If melatonin didn't work for you, the problem probably isn't in the melatonin receptors but in the stress axis.
- You want a long-term solution: Instead of taking something "for tonight", you want your body to gradually learn to relax on its own.
- You don't like pills: Corti-Glow is a sachet with forest fruits flavor — dissolve in 200–300ml of cold water and drink it 30-60 minutes before bed.
What the science says
About melatonin
A 2013 meta-analysis (Ferracioli-Oda et al., PLoS ONE) analyzed 19 studies with a total of 1683 participants. The conclusion: melatonin reduces time to fall asleep by an average of 7 minutes and increases total sleep duration by 8 minutes. The effect is statistically significant, but clinically — modest.
For jet lag the effect is significantly stronger — a 2002 Cochrane review (Herxheimer & Petrie) concludes that melatonin is "remarkably effective" when crossing 5+ time zones.
About ashwagandha (in Corti-Glow)
Chandrasekhar et al. (2012, Indian J Psychol Med) — 64 participants (mixed group), 300 mg twice daily (600 mg total) for 60 days. Result: -27.9% serum cortisol in the ashwagandha group vs. placebo. Participants also reported improved sleep quality (on PSS and GHQ-28 scales). In Corti-Glow — 300 mg of ashwagandha per sachet, tailored for long-term evening use in women.
Langade et al. (2019, Cureus) — 58 participants, 300 mg of ashwagandha for 8 weeks. Result: significant improvement in sleep quality (p<0.0001) and reduced time to fall asleep.
About magnesium (in Corti-Glow)
Abbasi et al. (2012, J Res Med Sci) — 46 adults with insomnia. In this trial, 500 mg of magnesium for 8 weeks was associated with improved ISI (Insomnia Severity Index), sleep efficiency, time to fall asleep, and higher serum melatonin.
About myo-inositol (in Corti-Glow)
Unfer et al. (2017, Expert Opinion on Drug Metabolism & Toxicology) — a systematic review of 12 studies in women with PCOS. Myo-inositol (2000-4000 mg/day) improves insulin sensitivity, hormonal balance, and ovulation. For sleep directly — the data is indirect, but hormonal balance is linked to sleep quality.
Note: Corti-Glow is a dietary supplement, not a medicine. It does not diagnose, treat, or prevent disease. Consult a doctor if you have chronic insomnia.
Questions and answers
Can I take Corti-Glow and melatonin at the same time?
Yes, there are no known interactions between the ingredients in Corti-Glow and melatonin. But if ashwagandha and magnesium are already helping you fall asleep, melatonin may be redundant. We recommend trying Corti-Glow alone for 4 weeks before deciding.
Why doesn't Corti-Glow contain melatonin?
The goal of Corti-Glow isn't to "switch off the brain" for sleep. Instead, the formula is built around the stress axis rather than sedation. When the body isn't in stress, it produces its own melatonin in sufficient amounts.
When should I choose melatonin over Corti-Glow?
Melatonin is more suitable for jet lag (travel across time zones), night shift work, or when you need a result the same evening. It's effective for single or short-term use (up to 2-4 weeks). If your problem is chronic stress, anxiety-driven insomnia, or PMS — Corti-Glow targets the root cause.
Melatonin is 10 times cheaper. Why pay more for Corti-Glow?
Melatonin is 1 ingredient in a small dose. Corti-Glow contains 7 ingredients in clinical doses: 2000 mg L-glycine, 2000 mg myo-inositol, 670 mg magnesium bisglycinate, 300 mg ashwagandha root extract, 250 mg choline bitartrate, 200 mg L-theanine, 1.4 mg vitamin B6. If you buy each separately, you'll pay 80-120 EUR per month.
