Everything about ingredients, doses, use and shipping, in plain language. Search by keyword or filter by category.
Is it safe for daily use?
Yes! Corti-Glow is designed as a daily supplement. The ingredients work best with consistent accumulation over time.
What does it taste like?
It tastes like a light, refreshing cocktail of wild strawberry and lime. Not bland, dissolves fully. We use stevia, so no blood sugar spike.
Can I take it while pregnant?
No. Ashwagandha is not recommended during pregnancy or breastfeeding. If you are pregnant, breastfeeding or planning a pregnancy — do not take Corti-Glow without explicit approval from your doctor.
When will I feel results?
Day 3 — easier falling asleep. Day 7 — reduced bloating. Day 14 — skin looks fresher. Day 30 — you feel the full difference (energy, mood, cycle). Consistent use is key to lasting results.
Are there side effects?
Corti-Glow is made from natural ingredients and is well tolerated. Rarely you may experience mild stomach sensitivity at the start, which passes.
How should I store the product?
Store in a dry, cool place away from direct sunlight. Refrigeration is not required.
What is myo-inositol and why is it in Corti-Glow?
Myo-inositol is a vitamin-like compound the body produces naturally. At 2000mg it has been studied in women with PCOS (polycystic ovary syndrome) — a meta-analysis in Gynecological Endocrinology shows improved menstrual regularity and insulin sensitivity. In Corti-Glow it is included for its effect on cycle regulation and sugar cravings caused by insulin swings. Not a medicine; does not replace treatment for PCOS.
What is the difference between magnesium bisglycinate and citrate?
Bisglycinate is magnesium bound to the amino acid glycine. It absorbs significantly better and doesn't irritate the stomach — unlike citrate or oxide, which at higher doses can have a laxative effect. Glycine itself has a calming action. In Corti-Glow we use bisglycinate (670mg, of which 100mg is elemental magnesium) — the form that reaches the brain and muscles without stomach discomfort.
How much ashwagandha is there and what is the effect?
300 mg of Withania somnifera root extract (≥5% withanolides). In a clinical study (Salve et al., Cureus, 2019), 600 mg daily lowered serum cortisol by 32.6% over 8 weeks. The sachet contains 300 mg — half the studied dose, for daily evening intake. The effect builds over time; it is not instant. The extract is a generic root extract, not a branded one.
Why L-theanine and not melatonin?
Melatonin is a hormone — it tells the brain to sleep, but does not work on the cause of insomnia. L-theanine is an amino acid from green tea: in studies at 200 mg, relaxation without drowsiness was observed (Hidese et al., 2019) — the sachet contains exactly 200 mg. Unlike melatonin, it is not a hormone and there are no data pointing to dependency or morning grogginess.
How do you prepare Corti-Glow?
Open one sachet and pour it into 250ml of cold water. Stir well — it dissolves fully, no lumps. Add ice and squeeze fresh lime if you like. Drink 30-60 minutes before bed. The whole process takes under 2 minutes. The pink colour comes from natural beetroot extract.
Can I take it with medications?
The ingredients in Corti-Glow are sold over-the-counter as dietary supplements. But if you take medications for thyroid, blood pressure, hormone therapy or antidepressants — consult a doctor. Ashwagandha may interact with thyroid medications, and magnesium can affect absorption of some antibiotics.
Can I drink more than one sachet per day?
We don't recommend it. The doses in one sachet are clinical — they match the amounts used in studies. More is not better. 2000mg of myo-inositol and 300mg of ashwagandha per day are enough for effect. If you have a specific health issue, talk to a doctor.
What is the difference between Corti-Glow and ordinary magnesium?
Ordinary magnesium is one ingredient. Corti-Glow contains 7 active ingredients at the doses they were studied at: magnesium bisglycinate 670 mg, L-glycine 2000 mg, myo-inositol 2000 mg, ashwagandha 300 mg (root extract), L-theanine 200 mg, choline bitartrate 250 mg and vitamin B6. Magnesium contributes to normal nervous-system and muscle function, and B6 to the regulation of hormonal activity (authorised EU claims). The remaining ingredients are included based on published studies — the numbers and sources are on the Science page.
Corti-Glow vs melatonin — which is better for sleep?
It depends on the cause. For jet lag or shift work melatonin makes sense — it signals the brain that it is night. Corti-Glow takes a different route: magnesium contributes to normal nervous-system function (authorised EU claim), and ashwagandha is included based on a clinical study — −32.6% serum cortisol at 600 mg over 8 weeks (Salve 2019); a sachet contains 300 mg. Corti-Glow contains no melatonin.
How much does it cost and are there discounts?
One box (30 sachets, for 1 month) is €49.99. Pack of 2 boxes — €89.99 (you save €10). Pack of 3 boxes — €119.99 (you save €30). Free shipping on orders over €80. We accept Visa, Mastercard, Apple Pay, Google Pay and cash on delivery.
How is it shipped and how long does it take?
Shipping is with a courier of your choice — Speedy, ExpressOne or SAMEDAY — to an Econt office or to your address. Order processing: up to 1 business day. Delivery: 1-2 business days. You have 14 days right of return, no questions asked.
What is cortisol belly?
When cortisol (the stress hormone) is chronically elevated, the body stores fat mainly around the belly. It is not a question of calories — even women who eat well and train can have this pattern. The ashwagandha in Corti-Glow is included based on a clinical study: −32.6% serum cortisol at 600 mg over 8 weeks (Salve 2019); the sachet contains 300 mg. Myo-inositol and L-glycine are dosed per their respective studies — the numbers are on the Science page.
Does it help with PCOS (polycystic ovary syndrome)?
Myo-inositol (2000mg in Corti-Glow) is the most-studied supplement for PCOS. A meta-analysis (Unfer et al., 2017) shows improved menstrual regularity, ovulation and insulin sensitivity. Ashwagandha complements by lowering cortisol — elevated stress worsens PCOS. Corti-Glow is not a medicine and does not replace medical treatment. Consult an endocrinologist for a specific plan.
